1 00:00:09,200 --> 00:00:06,760 welcome to NASA's Jet Propulsion 2 00:00:11,600 --> 00:00:09,210 Laboratory I'm Jane Platt with the media 3 00:00:14,330 --> 00:00:11,610 relations office oh the Mars Curiosity 4 00:00:17,090 --> 00:00:14,340 rover is settling in well into its new 5 00:00:19,670 --> 00:00:17,100 home on Mars and I guess we could say 6 00:00:21,400 --> 00:00:19,680 it's really on a roll right now we're 7 00:00:23,420 --> 00:00:21,410 going to be hearing from a panel of 8 00:00:25,880 --> 00:00:23,430 scientists and engineers to tell us 9 00:00:27,349 --> 00:00:25,890 what's going on but first I did want to 10 00:00:29,810 --> 00:00:27,359 mention that today has been declared 11 00:00:32,420 --> 00:00:29,820 space day by California Governor Jerry 12 00:00:34,940 --> 00:00:32,430 Brown who will be visiting JPL and 13 00:00:36,229 --> 00:00:34,950 meeting with the rover team later on but 14 00:00:38,720 --> 00:00:36,239 in the meantime we're going to start 15 00:00:40,310 --> 00:00:38,730 with our panel and we're going to 16 00:00:42,889 --> 00:00:40,320 introduce them first of all we have 17 00:00:45,260 --> 00:00:42,899 Michael Meyer he's the lead scientist 18 00:00:47,959 --> 00:00:45,270 for the Mars exploration program NASA 19 00:00:51,439 --> 00:00:47,969 headquarters in Washington we have Pete 20 00:00:54,200 --> 00:00:51,449 tysinger the MSL project manager for a 21 00:00:56,330 --> 00:00:54,210 Jet Propulsion Laboratory and we have 22 00:00:59,119 --> 00:00:56,340 Roger Weems principal investigator of 23 00:01:05,750 --> 00:00:59,129 the chemcam instrument Los Alamos 24 00:01:07,850 --> 00:01:05,760 National Laboratory in New Mexico Matt 25 00:01:10,520 --> 00:01:07,860 hive early mat heavily is next and he's 26 00:01:13,370 --> 00:01:10,530 the lead Rover planner for he's are at 27 00:01:15,530 --> 00:01:13,380 JPL and Roger Weems then is the 28 00:01:18,230 --> 00:01:15,540 principal investigator at chemcam from 29 00:01:20,810 --> 00:01:18,240 Los Alamos in New Mexico and we have 30 00:01:24,020 --> 00:01:20,820 last but not least joy crisp the deputy 31 00:01:25,370 --> 00:01:24,030 project scientist at JPL we're going to 32 00:01:27,280 --> 00:01:25,380 start things off this morning with a 33 00:01:30,230 --> 00:01:27,290 special announcement from Michael Meyer 34 00:01:31,730 --> 00:01:30,240 well thank you actually before I make 35 00:01:33,620 --> 00:01:31,740 the announcement which I think all of 36 00:01:37,100 --> 00:01:33,630 you will enjoy I would like to show you 37 00:01:40,810 --> 00:01:37,110 a short video this video was made on the 38 00:01:45,469 --> 00:01:40,820 eve of the arrival at Mars of Mariner 9 39 00:01:47,090 --> 00:01:45,479 this was in November of 1971 and in the 40 00:01:50,380 --> 00:01:47,100 video you'll see a couple people you 41 00:01:54,530 --> 00:01:50,390 might recognize like Bruce Murray and 42 00:01:57,679 --> 00:01:54,540 Carl Sagan and Ray Bradbury so we can 43 00:02:00,200 --> 00:01:57,689 look at that video I was hoping that 44 00:02:03,469 --> 00:02:00,210 during the last few days as we got 45 00:02:05,240 --> 00:02:03,479 closer to Mars and the dust cleared that 46 00:02:12,750 --> 00:02:05,250 we see a lot of Martian standing there 47 00:02:22,980 --> 00:02:14,570 you 48 00:02:24,990 --> 00:02:22,990 brought along too though I'm going to 49 00:02:27,480 --> 00:02:25,000 keep this short because I much rather 50 00:02:29,700 --> 00:02:27,490 listen to our scientific friends here 51 00:02:31,980 --> 00:02:29,710 today tell us about what's coming up 52 00:02:33,690 --> 00:02:31,990 this week but I every time I get a group 53 00:02:37,020 --> 00:02:33,700 of people together and have them trapped 54 00:02:40,800 --> 00:02:37,030 in a pile like this i bring a poem say 55 00:02:43,200 --> 00:02:40,810 and you can't escape me but luckily it's 56 00:02:45,630 --> 00:02:43,210 a short poem but it sums up some of my 57 00:02:47,370 --> 00:02:45,640 feelings on why i love space travel why 58 00:02:49,290 --> 00:02:47,380 i write science fiction why i'm 59 00:02:53,360 --> 00:02:49,300 intrigued with what's going on this 60 00:02:55,500 --> 00:02:53,370 weekend of Mars and part of this has my 61 00:02:57,840 --> 00:02:55,510 philosophy about space travel and 62 00:03:00,390 --> 00:02:57,850 initial permit are read it to you it's 63 00:03:02,700 --> 00:03:00,400 very very short the fence we walked 64 00:03:05,340 --> 00:03:02,710 between the years that balance us serene 65 00:03:07,230 --> 00:03:05,350 was a place half in the sky we're in the 66 00:03:09,720 --> 00:03:07,240 green of leaf and promising of peach 67 00:03:12,210 --> 00:03:09,730 we've reached our hand attention almost 68 00:03:15,750 --> 00:03:12,220 touched the sky if we could reach and 69 00:03:20,130 --> 00:03:15,760 touch me said it strategist not to never 70 00:03:22,380 --> 00:03:20,140 to be dead we ate and almost touched 71 00:03:25,290 --> 00:03:22,390 that stuff our reach was never quite 72 00:03:28,410 --> 00:03:25,300 enough if only we had Tyler bin and 73 00:03:30,479 --> 00:03:28,420 touched God's cuff is his hem we would 74 00:03:33,540 --> 00:03:30,489 not have to go with them who have gone 75 00:03:36,540 --> 00:03:33,550 before who sure does us two towels they 76 00:03:38,760 --> 00:03:36,550 could stand and hopes by stretching tell 77 00:03:41,240 --> 00:03:38,770 that they might keep their land their 78 00:03:44,009 --> 00:03:41,250 home their heart their flesh and sold 79 00:03:47,910 --> 00:03:44,019 but they like us for standing in a hole 80 00:03:51,060 --> 00:03:47,920 Oh Thomas will erase one day stand 81 00:03:53,280 --> 00:03:51,070 really tower across the void across the 82 00:03:56,280 --> 00:03:53,290 universe and all and measured out with 83 00:03:59,430 --> 00:03:56,290 rocket fire at last put Adams finger 84 00:04:02,940 --> 00:03:59,440 fourth as on the Sistine ceiling and 85 00:04:06,120 --> 00:04:02,950 God's hand come down the other way to 86 00:04:09,240 --> 00:04:06,130 measure man and find him good and gift 87 00:04:13,620 --> 00:04:09,250 him with forevers day I worked for that 88 00:04:16,830 --> 00:04:13,630 short man large dream i send my rockets 89 00:04:19,240 --> 00:04:16,840 forth between my ears hoping an inch of 90 00:04:22,240 --> 00:04:19,250 good is worth a pound of years 91 00:04:25,180 --> 00:04:22,250 aching to hear a voice cried back around 92 00:04:39,540 --> 00:04:25,190 the universal man we've reached Alpha 93 00:04:51,880 --> 00:04:45,610 and today Saul 16 we had the first 94 00:04:53,620 --> 00:04:51,890 roving astrobiology rover on Mars and we 95 00:04:56,980 --> 00:04:53,630 have truly extended our reach and 96 00:05:01,420 --> 00:04:56,990 touched another planet today would have 97 00:05:03,460 --> 00:05:01,430 been Ray Bradbury's 92nd birthday but he 98 00:05:05,440 --> 00:05:03,470 has already reached in mortality with 99 00:05:10,750 --> 00:05:05,450 the hundreds of short stories he's 100 00:05:12,730 --> 00:05:10,760 written and nearly 50 books his books 101 00:05:15,490 --> 00:05:12,740 have truly inspired us the Martian 102 00:05:18,250 --> 00:05:15,500 Chronicles have inspired our curiosity 103 00:05:22,480 --> 00:05:18,260 and open our minds of the possibility of 104 00:05:25,420 --> 00:05:22,490 life on Mars in his honor we declared 105 00:05:28,990 --> 00:05:25,430 the place that that curiosity touched 106 00:05:34,330 --> 00:05:29,000 down to be it forever known as Bradbury 107 00:05:36,880 --> 00:05:34,340 landing I kind of like the name for one 108 00:05:39,730 --> 00:05:36,890 it was you know the majority vote of the 109 00:05:42,640 --> 00:05:39,740 science team having been inspired by Ray 110 00:05:46,630 --> 00:05:42,650 Bradbury landing is actually an event 111 00:05:49,000 --> 00:05:46,640 it's not an object also it harkens back 112 00:05:51,850 --> 00:05:49,010 to the time when ships landed on the 113 00:05:58,810 --> 00:05:51,860 shores of other new worlds to explore 114 00:06:03,520 --> 00:05:58,820 and this place might in fact with its 115 00:06:06,159 --> 00:06:03,530 water reference be even more apropos so 116 00:06:07,990 --> 00:06:06,169 I would like to choose I would like to 117 00:06:10,120 --> 00:06:08,000 relay to you one of my favorite scene 118 00:06:12,700 --> 00:06:10,130 from the Martian Chronicles and that was 119 00:06:16,330 --> 00:06:12,710 when the humans peer over the rim of one 120 00:06:18,719 --> 00:06:16,340 of the Martian canals and there they see 121 00:06:23,320 --> 00:06:18,729 reflected in the water Martians and 122 00:06:25,930 --> 00:06:23,330 themselves and so as we look forward to 123 00:06:27,909 --> 00:06:25,940 one of those days I would like to now 124 00:06:31,390 --> 00:06:27,919 turn it over to peek tysinger who will 125 00:06:33,600 --> 00:06:31,400 tell us about our intrepid Martian the 126 00:06:37,270 --> 00:06:33,610 rover Curiosity 127 00:06:39,640 --> 00:06:37,280 thank you Mike um i would like before i 128 00:06:48,219 --> 00:06:39,650 start to give a small hand of applause 129 00:06:50,439 --> 00:06:48,229 to Ray Bradbury he was a friend of JPL 130 00:06:52,600 --> 00:06:50,449 as well as of the total space program 131 00:06:54,670 --> 00:06:52,610 and and and several people including 132 00:06:58,809 --> 00:06:54,680 myself had the honor of meeting him and 133 00:07:00,969 --> 00:06:58,819 and so very apropos gesture um you are 134 00:07:04,240 --> 00:07:00,979 looking here today at a very smiley 135 00:07:06,520 --> 00:07:04,250 ecstatic project manager we have 136 00:07:09,040 --> 00:07:06,530 completed 16 souls on the surface and 137 00:07:13,270 --> 00:07:09,050 everything has been going extremely well 138 00:07:14,950 --> 00:07:13,280 I mean really extremely well we have no 139 00:07:17,020 --> 00:07:14,960 anomalies or other issues that we're 140 00:07:19,420 --> 00:07:17,030 working with the exception of the rims 141 00:07:22,390 --> 00:07:19,430 win sensor anomaly which is still in 142 00:07:25,270 --> 00:07:22,400 work and if I could have the first slide 143 00:07:28,059 --> 00:07:25,280 please I kind of like to take you back 144 00:07:29,529 --> 00:07:28,069 to to the day before landing I think 145 00:07:31,480 --> 00:07:29,539 Richard cooks that on the stage and 146 00:07:33,790 --> 00:07:31,490 talked about what the near-term plans 147 00:07:35,469 --> 00:07:33,800 were going to be after 10 31 on that 148 00:07:37,540 --> 00:07:35,479 Sunday evening I'd like to kind of let 149 00:07:39,820 --> 00:07:37,550 you know what's happened in the early 150 00:07:40,990 --> 00:07:39,830 first week of the planned activities we 151 00:07:42,850 --> 00:07:41,000 were going to do the high-gain antenna 152 00:07:45,459 --> 00:07:42,860 deploy mass deploy instrumen aliveness 153 00:07:46,839 --> 00:07:45,469 checks acquire panorama we had a quiet 154 00:07:48,640 --> 00:07:46,849 day planned and we were going to start 155 00:07:50,320 --> 00:07:48,650 and then a few days later finish the 156 00:07:52,029 --> 00:07:50,330 flight software changed the surface load 157 00:07:53,469 --> 00:07:52,039 and notice that check marks because 158 00:07:56,769 --> 00:07:53,479 we've successfully completed all those 159 00:08:00,550 --> 00:07:56,779 activities basically on plan next slide 160 00:08:03,219 --> 00:08:00,560 please and this was kind of the longer 161 00:08:04,540 --> 00:08:03,229 view going forward in early August we 162 00:08:06,010 --> 00:08:04,550 were going to get the first images and 163 00:08:08,860 --> 00:08:06,020 finished the engineering check out and 164 00:08:10,570 --> 00:08:08,870 we've completed that activity in mid to 165 00:08:14,170 --> 00:08:10,580 late august we were complete the payload 166 00:08:15,490 --> 00:08:14,180 checkouts and we've done that and and 167 00:08:17,499 --> 00:08:15,500 we're going to check out the sample 168 00:08:20,379 --> 00:08:17,509 system and we have not quite completed 169 00:08:21,730 --> 00:08:20,389 that work we have done a short drive 170 00:08:23,469 --> 00:08:21,740 today that Matt will talk about in a 171 00:08:26,189 --> 00:08:23,479 second and with that activity we have 172 00:08:30,159 --> 00:08:26,199 completed the characterization phase a 173 00:08:32,319 --> 00:08:30,169 1-1 both a and B if you recall in that 174 00:08:34,449 --> 00:08:32,329 plan of there's going to be an 175 00:08:37,060 --> 00:08:34,459 intermission between cap 1 and cap too 176 00:08:38,649 --> 00:08:37,070 and that is going to take place and and 177 00:08:41,920 --> 00:08:38,659 that intermission is likely to be a 178 00:08:44,350 --> 00:08:41,930 little bit more extended and so and so 179 00:08:46,060 --> 00:08:44,360 rather than do the surface sample 180 00:08:46,480 --> 00:08:46,070 checkouts and then the first drive I 181 00:08:47,710 --> 00:08:46,490 think this 182 00:08:49,620 --> 00:08:47,720 scientists have decided we're going to 183 00:08:51,850 --> 00:08:49,630 take a little bit of an extensive drive 184 00:08:54,340 --> 00:08:51,860 since we now know the system works well 185 00:08:57,550 --> 00:08:54,350 and and then we will complete the sample 186 00:08:59,110 --> 00:08:57,560 system checkouts later in August we 187 00:09:01,510 --> 00:08:59,120 still ought to be able to complete a 188 00:09:04,240 --> 00:09:01,520 scoop sample in midair late-september on 189 00:09:06,280 --> 00:09:04,250 plan and Anna first drill symbol in 190 00:09:08,079 --> 00:09:06,290 October November so right now a little 191 00:09:10,930 --> 00:09:08,089 bit more intermission a little bit more 192 00:09:13,210 --> 00:09:10,940 science from that and and and but we're 193 00:09:15,579 --> 00:09:13,220 basically on plan with what I like to 194 00:09:18,130 --> 00:09:15,589 repeat is that extremely well behaved a 195 00:09:21,190 --> 00:09:18,140 flight system on Mars and Matt will tell 196 00:09:22,720 --> 00:09:21,200 us about today's drive thanks Pete so 197 00:09:25,540 --> 00:09:22,730 let's get straight to the good stuff and 198 00:09:28,090 --> 00:09:25,550 put up the image from today the very 199 00:09:30,280 --> 00:09:28,100 beautiful image so I'm pleased to report 200 00:09:39,160 --> 00:09:30,290 that curiosity today had our first 201 00:09:41,530 --> 00:09:39,170 successful drive on Mars so this this 202 00:09:43,210 --> 00:09:41,540 Drive check out coupled with yester 203 00:09:45,190 --> 00:09:43,220 Sol's check out of the steering 204 00:09:47,949 --> 00:09:45,200 actuators on cell 15 means that we have 205 00:09:50,199 --> 00:09:47,959 a fully functioning mobility system on 206 00:09:52,210 --> 00:09:50,209 our Rover and in this image you can see 207 00:09:53,650 --> 00:09:52,220 our touchdown point you can see the 208 00:09:56,769 --> 00:09:53,660 tracks driving away from that location 209 00:09:58,960 --> 00:09:56,779 as well as the scour marks to the right 210 00:10:01,630 --> 00:09:58,970 and the left of the rover's initial 211 00:10:04,269 --> 00:10:01,640 position we drove forward did it turn in 212 00:10:06,069 --> 00:10:04,279 place and backed up and you can see that 213 00:10:08,500 --> 00:10:06,079 the the soil underneath the rover it 214 00:10:11,199 --> 00:10:08,510 kind of confirms our expectations that 215 00:10:13,780 --> 00:10:11,209 the soil is firm great for mobility 216 00:10:15,310 --> 00:10:13,790 we're not in seeing too much sinkage and 217 00:10:17,740 --> 00:10:15,320 that we should have smooth sailing ahead 218 00:10:19,810 --> 00:10:17,750 of us I've also got another graphic 219 00:10:23,819 --> 00:10:19,820 showing the animation of the drive today 220 00:10:26,170 --> 00:10:23,829 if we can move to that so this is our 221 00:10:28,090 --> 00:10:26,180 simulation and visualization tool which 222 00:10:30,280 --> 00:10:28,100 shows our first drive so we initially 223 00:10:32,800 --> 00:10:30,290 bumped forward 90 centimeters to image 224 00:10:34,650 --> 00:10:32,810 the wheels and then drove an additional 225 00:10:37,600 --> 00:10:34,660 distance to total four and a half meters 226 00:10:38,949 --> 00:10:37,610 where we did our first turn in place and 227 00:10:40,480 --> 00:10:38,959 you can see we're imaging every once in 228 00:10:41,829 --> 00:10:40,490 a while to look at the wheels as we're 229 00:10:44,880 --> 00:10:41,839 driving to inspect them and check them 230 00:10:47,500 --> 00:10:44,890 out turning half of our 120 degree turn 231 00:10:50,260 --> 00:10:47,510 turning the remaining distance and then 232 00:10:52,449 --> 00:10:50,270 backing up two and a half meters so this 233 00:10:55,000 --> 00:10:52,459 final location places us in a good spot 234 00:10:56,650 --> 00:10:55,010 to do some good science here we've got 235 00:10:58,780 --> 00:10:56,660 the gold burns scour off to the right 236 00:11:00,100 --> 00:10:58,790 side of the rover where we can view it 237 00:11:00,310 --> 00:11:00,110 with the chemcam instrument and the 238 00:11:02,290 --> 00:11:00,320 other 239 00:11:04,270 --> 00:11:02,300 instruments the key things about the 240 00:11:05,830 --> 00:11:04,280 drive today were that we were able to do 241 00:11:07,750 --> 00:11:05,840 one full revolution of the drive 242 00:11:09,700 --> 00:11:07,760 actuators in the forward direction we 243 00:11:11,380 --> 00:11:09,710 were able to turn and see that the 244 00:11:13,540 --> 00:11:11,390 inertial measurement unit telling the 245 00:11:15,100 --> 00:11:13,550 rover how it's heading is changing is 246 00:11:16,780 --> 00:11:15,110 working properly and we were able to 247 00:11:19,180 --> 00:11:16,790 back up another full revolution of the 248 00:11:20,590 --> 00:11:19,190 drive actuators so we were able to see 249 00:11:22,840 --> 00:11:20,600 motor currents we were able to get the 250 00:11:25,780 --> 00:11:22,850 data and everything looks perfectly 251 00:11:28,900 --> 00:11:25,790 nominal so we're very excited to to have 252 00:11:30,820 --> 00:11:28,910 this kind of milestone behind us we see 253 00:11:32,920 --> 00:11:30,830 that the system is performing very well 254 00:11:34,780 --> 00:11:32,930 and we're in a great place to do some 255 00:11:38,830 --> 00:11:34,790 science so with that I'll pass it over 256 00:11:41,590 --> 00:11:38,840 to Roger thanks Matt exciting so I'm 257 00:11:43,900 --> 00:11:41,600 going to talk about the check out of the 258 00:11:47,080 --> 00:11:43,910 chemcam instrument and some of the first 259 00:11:50,110 --> 00:11:47,090 science with it the chemcam is the laser 260 00:11:54,160 --> 00:11:50,120 instrument which fires high-energy 261 00:11:58,270 --> 00:11:54,170 pulses at targets up to almost 25 feet 262 00:12:00,940 --> 00:11:58,280 away so it that produces plasmas that 263 00:12:05,080 --> 00:12:00,950 provide chemical composition of the 264 00:12:07,600 --> 00:12:05,090 samples for us to to understand so we're 265 00:12:09,850 --> 00:12:07,610 going to cut to a video here which will 266 00:12:11,350 --> 00:12:09,860 show a demonstration before we 267 00:12:14,170 --> 00:12:11,360 integrated this instrument onto the 268 00:12:15,970 --> 00:12:14,180 rover so here is the mast part of the 269 00:12:18,220 --> 00:12:15,980 chemcam instrument you see a four and a 270 00:12:20,830 --> 00:12:18,230 half inch telescope there the laser is 271 00:12:22,240 --> 00:12:20,840 right behind and we're going to show a 272 00:12:24,190 --> 00:12:22,250 little demonstration where this 273 00:12:26,950 --> 00:12:24,200 instrument is going to be used to fire 274 00:12:29,410 --> 00:12:26,960 at an iron pyrite target about eight 275 00:12:31,660 --> 00:12:29,420 feet away so we're setting it up here 276 00:12:34,120 --> 00:12:31,670 the laser beam is invisible but you 277 00:12:36,820 --> 00:12:34,130 actually see the plasmas first at three 278 00:12:38,620 --> 00:12:36,830 hurtz here and then at ten Hertz so 279 00:12:40,840 --> 00:12:38,630 you'll see how it can shoot and then we 280 00:12:42,040 --> 00:12:40,850 just show a still image of the plasma so 281 00:12:45,280 --> 00:12:42,050 you can see what it really looks like 282 00:12:47,440 --> 00:12:45,290 missed this test was done at terrestrial 283 00:12:50,560 --> 00:12:47,450 pressure it was done in Los Alamos 284 00:12:52,600 --> 00:12:50,570 National Lab and the plasmas are more 285 00:12:54,910 --> 00:12:52,610 confined in a terrestrial atmosphere 286 00:12:56,890 --> 00:12:54,920 than the air on Mars and so if we show 287 00:12:58,620 --> 00:12:56,900 the next image you'll actually see the 288 00:13:02,050 --> 00:12:58,630 difference so on the Left you'll see 289 00:13:04,270 --> 00:13:02,060 what a plasma looks like at in a 290 00:13:05,710 --> 00:13:04,280 terrestrial environment that's but this 291 00:13:07,900 --> 00:13:05,720 was in a chamber and so then we 292 00:13:10,360 --> 00:13:07,910 evacuated it down to Mars pressure which 293 00:13:12,700 --> 00:13:10,370 is about 1% of Earth's pressure and on 294 00:13:13,870 --> 00:13:12,710 the right you can see the size and 295 00:13:16,480 --> 00:13:13,880 brilliance of the plasma 296 00:13:18,130 --> 00:13:16,490 mars pressure and so on the right is 297 00:13:22,660 --> 00:13:18,140 what's actually happening now on Mars 298 00:13:24,580 --> 00:13:22,670 and so as you and you know the the short 299 00:13:30,880 --> 00:13:24,590 of this is that that we were getting 300 00:13:33,640 --> 00:13:30,890 great signal so far so basically chemcam 301 00:13:37,710 --> 00:13:33,650 also includes a remote micro imager so 302 00:13:40,210 --> 00:13:37,720 this imager is designed to take close-up 303 00:13:42,400 --> 00:13:40,220 high-resolution images to provide the 304 00:13:44,830 --> 00:13:42,410 context for these small analysis spots 305 00:13:47,650 --> 00:13:44,840 that we hit with the laser but it can 306 00:13:50,260 --> 00:13:47,660 also image other areas as well so until 307 00:13:51,670 --> 00:13:50,270 we pull out the mastcam 100 and start 308 00:13:55,560 --> 00:13:51,680 using that this is a highest resolution 309 00:13:58,810 --> 00:13:55,570 imager on the rover for right now so 310 00:14:02,320 --> 00:13:58,820 basically in the next image will show 311 00:14:04,960 --> 00:14:02,330 the rock that we first analyzed on the 312 00:14:08,200 --> 00:14:04,970 surface of Mars this was a rock called 313 00:14:11,140 --> 00:14:08,210 coronation it was it was selected 314 00:14:14,020 --> 00:14:11,150 because it was at a nice distance from 315 00:14:16,060 --> 00:14:14,030 the rover it had a nice flat face the 316 00:14:19,210 --> 00:14:16,070 rock itself is about only three inches 317 00:14:22,390 --> 00:14:19,220 across and it's about let's see about 318 00:14:24,580 --> 00:14:22,400 eight feet from the instrument and so we 319 00:14:28,270 --> 00:14:24,590 sent up the commands on Saturday night 320 00:14:31,030 --> 00:14:28,280 and the spectra came back on early on 321 00:14:33,850 --> 00:14:31,040 Sunday morning and we had a very excited 322 00:14:36,040 --> 00:14:33,860 team to look at this and actually the 323 00:14:37,930 --> 00:14:36,050 way the way we did this we actually took 324 00:14:40,510 --> 00:14:37,940 an image the day before and then and 325 00:14:42,460 --> 00:14:40,520 then repointed just slightly so the 326 00:14:44,110 --> 00:14:42,470 image you see on this on this picture is 327 00:14:46,390 --> 00:14:44,120 just a little bit off but the next day 328 00:14:48,520 --> 00:14:46,400 we got it right in the middle and we 329 00:14:51,160 --> 00:14:48,530 show a little inset of where where it 330 00:14:54,180 --> 00:14:51,170 hit on the rock and I'll show another 331 00:14:57,490 --> 00:14:54,190 one like that a little bit later but the 332 00:15:01,030 --> 00:14:57,500 next slide will show is actually the the 333 00:15:04,030 --> 00:15:01,040 spectrum from this rock in short we got 334 00:15:06,810 --> 00:15:04,040 excellent signal we actually saturated 335 00:15:09,610 --> 00:15:06,820 one emission-line oxygen just slightly 336 00:15:12,580 --> 00:15:09,620 so that just shows what good signal 337 00:15:17,140 --> 00:15:12,590 we're getting from from Mars so the 338 00:15:19,600 --> 00:15:17,150 spectrum consists of 6144 channels that 339 00:15:23,320 --> 00:15:19,610 span the wavelength range from 240 to 340 00:15:25,620 --> 00:15:23,330 850 nanometers and so that covers the 341 00:15:27,220 --> 00:15:25,630 ultraviolet with one spectrometer a 342 00:15:28,720 --> 00:15:27,230 violet and blue ray 343 00:15:31,260 --> 00:15:28,730 change with another spectrometer and 344 00:15:34,840 --> 00:15:31,270 then the visible and near-infrared range 345 00:15:36,880 --> 00:15:34,850 that Ric with the third spectrometer and 346 00:15:40,600 --> 00:15:36,890 so a color covers all the rainbow colors 347 00:15:42,670 --> 00:15:40,610 plus a bunch on both sides and so you 348 00:15:44,530 --> 00:15:42,680 can see labeled on there a number of 349 00:15:46,270 --> 00:15:44,540 emission lines that represent different 350 00:15:48,400 --> 00:15:46,280 elements and so those are the things we 351 00:15:51,160 --> 00:15:48,410 look for and so we can see the major 352 00:15:55,260 --> 00:15:51,170 elements on here oxygen silicon 353 00:15:57,910 --> 00:15:55,270 magnesium iron sodium potassium calcium 354 00:15:59,620 --> 00:15:57,920 but there's also minor and trace 355 00:16:01,450 --> 00:15:59,630 elements that we can really pick up with 356 00:16:04,600 --> 00:16:01,460 this instrument and so the inset on the 357 00:16:07,920 --> 00:16:04,610 upper left actually shows titanium and 358 00:16:11,680 --> 00:16:07,930 manganese which are which are quite 359 00:16:13,600 --> 00:16:11,690 lower in composition and also if you'll 360 00:16:15,580 --> 00:16:13,610 if you look you can see a lithium 361 00:16:18,760 --> 00:16:15,590 pointed out as well and that's probably 362 00:16:20,200 --> 00:16:18,770 less than 50 parts per million so 363 00:16:22,300 --> 00:16:20,210 there's a lot of detail we can get from 364 00:16:24,520 --> 00:16:22,310 this instrument and so we're really 365 00:16:26,590 --> 00:16:24,530 excited about that just one more thing 366 00:16:30,280 --> 00:16:26,600 about that is the inset near the center 367 00:16:33,340 --> 00:16:30,290 which shows the peaks of hydrogen and 368 00:16:35,560 --> 00:16:33,350 carbon the carbon peak on the right of 369 00:16:37,780 --> 00:16:35,570 this inset is from the atmosphere so 370 00:16:40,300 --> 00:16:37,790 there's nothing real big there in terms 371 00:16:43,690 --> 00:16:40,310 of findings the peak on the left showing 372 00:16:46,960 --> 00:16:43,700 hydrogen this is actually a sequence 373 00:16:50,260 --> 00:16:46,970 plot which shows every single laser shot 374 00:16:52,690 --> 00:16:50,270 as a separate spectrum and we did 30 375 00:16:55,870 --> 00:16:52,700 shots here and so the the first shot is 376 00:16:57,430 --> 00:16:55,880 shown in the white and that curve shows 377 00:16:59,530 --> 00:16:57,440 that we actually had hydrogen on the 378 00:17:00,850 --> 00:16:59,540 first shot but then I went down we could 379 00:17:02,770 --> 00:17:00,860 barely see it on the second shot and 380 00:17:04,840 --> 00:17:02,780 then it went away so it shows us that on 381 00:17:07,480 --> 00:17:04,850 the very surface of this rock we had 382 00:17:09,280 --> 00:17:07,490 hydrogen another thing that we saw on 383 00:17:12,550 --> 00:17:09,290 the surface was an enhancement of 384 00:17:13,960 --> 00:17:12,560 magnesium so we saw this on Coronation 385 00:17:15,640 --> 00:17:13,970 we also saw this on all of the samples 386 00:17:17,800 --> 00:17:15,650 we've looked at so far including the 387 00:17:19,750 --> 00:17:17,810 calibration target on the rover so this 388 00:17:21,460 --> 00:17:19,760 may be indicative of something from the 389 00:17:24,610 --> 00:17:21,470 dust where we've got to look into this a 390 00:17:27,190 --> 00:17:24,620 little bit more okay so after this rock 391 00:17:28,960 --> 00:17:27,200 we kind of told the science team that 392 00:17:31,840 --> 00:17:28,970 they were free to start choosing some 393 00:17:34,180 --> 00:17:31,850 targets and they went and selected the 394 00:17:37,150 --> 00:17:34,190 Goulburn scour this is the area where 395 00:17:38,710 --> 00:17:37,160 the rover's or the sky cranes thrusters 396 00:17:40,570 --> 00:17:38,720 actually sort of dug in a little bit 397 00:17:43,090 --> 00:17:40,580 with the blast 398 00:17:45,190 --> 00:17:43,100 and they uncovered a small rock outcrop 399 00:17:47,470 --> 00:17:45,200 which is of interest because of the way 400 00:17:49,419 --> 00:17:47,480 it looks it looks as if may have some 401 00:17:51,130 --> 00:17:49,429 some of the layers in it and it's 402 00:17:55,810 --> 00:17:51,140 bedrock so if we can go to the next 403 00:17:59,409 --> 00:17:55,820 image umm so the this image shows a mast 404 00:18:01,990 --> 00:17:59,419 cam a 34 image in the center and it is 405 00:18:05,970 --> 00:18:02,000 labeled with the locations of the remote 406 00:18:08,680 --> 00:18:05,980 micro imager that's chem cams imager 407 00:18:10,240 --> 00:18:08,690 pictures that were taken pictures one 408 00:18:13,149 --> 00:18:10,250 through six these are the little round 409 00:18:15,279 --> 00:18:13,159 images that show high resolution and so 410 00:18:18,909 --> 00:18:15,289 we targeted this for both imaging and we 411 00:18:21,669 --> 00:18:18,919 targeted Goulburn locations two three 412 00:18:24,669 --> 00:18:21,679 and four for the laser as well and so we 413 00:18:28,690 --> 00:18:24,679 shot the laser at the center of these of 414 00:18:31,149 --> 00:18:28,700 these images and so the the results we 415 00:18:33,940 --> 00:18:31,159 got there are pretty consistent with 416 00:18:36,580 --> 00:18:33,950 what we saw on coronation the coronation 417 00:18:39,789 --> 00:18:36,590 results really look like a basaltic 418 00:18:41,950 --> 00:18:39,799 composition and so that's not too 419 00:18:43,659 --> 00:18:41,960 surprising for the surface of Mars we 420 00:18:47,860 --> 00:18:43,669 know that basalt is the major igneous 421 00:18:49,690 --> 00:18:47,870 rock on Mars the fact that goulburn 422 00:18:52,419 --> 00:18:49,700 which looks a little bit sedimentary 423 00:18:54,490 --> 00:18:52,429 shows a basaltic composition is also not 424 00:18:56,950 --> 00:18:54,500 too surprising because when we look at 425 00:18:58,860 --> 00:18:56,960 this close up with our mi the remote 426 00:19:01,690 --> 00:18:58,870 micro imager we see that there are 427 00:19:03,970 --> 00:19:01,700 clasts or rock fragments that look like 428 00:19:06,340 --> 00:19:03,980 they were probably basaltic as well and 429 00:19:08,620 --> 00:19:06,350 so if this is a sedimentary rock and 430 00:19:11,409 --> 00:19:08,630 incorporated and loosely cemented some 431 00:19:13,240 --> 00:19:11,419 of these basaltic rock fragments some of 432 00:19:15,759 --> 00:19:13,250 them are our angular so they looked like 433 00:19:18,279 --> 00:19:15,769 they didn't get much altered and some of 434 00:19:21,220 --> 00:19:18,289 them are a little bit more rounded so 435 00:19:23,529 --> 00:19:21,230 that's kind of the story we've also shot 436 00:19:25,779 --> 00:19:23,539 a couple of other rocks one of them did 437 00:19:27,850 --> 00:19:25,789 give a different composition but it's 438 00:19:29,799 --> 00:19:27,860 still consistent with an igneous rock it 439 00:19:33,879 --> 00:19:29,809 looks like we hit more of a mineral 440 00:19:35,680 --> 00:19:33,889 grain potentially plagioclase but it's 441 00:19:37,629 --> 00:19:35,690 still consistent with a basaltic 442 00:19:39,700 --> 00:19:37,639 composition but because of the small 443 00:19:41,710 --> 00:19:39,710 spots that chemcam can shoot we can get 444 00:19:43,960 --> 00:19:41,720 single mineral grains if that's a larger 445 00:19:46,990 --> 00:19:43,970 grained rock what we'll need to do is 446 00:19:49,659 --> 00:19:47,000 move towards doing rasters and in line 447 00:19:51,879 --> 00:19:49,669 scans so we get more analysis spots on 448 00:19:53,409 --> 00:19:51,889 single rocks so we can really tell so 449 00:19:54,220 --> 00:19:53,419 we're still working on checking some of 450 00:19:56,260 --> 00:19:54,230 those things out 451 00:19:59,710 --> 00:19:56,270 so I'm just going to show up a final 452 00:20:03,010 --> 00:19:59,720 image which is actually the Goulburn 453 00:20:04,960 --> 00:20:03,020 number three and this is a an animation 454 00:20:07,810 --> 00:20:04,970 to just cuts between a before-and-after 455 00:20:10,510 --> 00:20:07,820 image that we shot that we took with 456 00:20:12,039 --> 00:20:10,520 with the micro imager showing what the 457 00:20:14,320 --> 00:20:12,049 rock looks like just before and just 458 00:20:16,270 --> 00:20:14,330 after shooting with the laser and so you 459 00:20:19,240 --> 00:20:16,280 can see how we can see where the laser 460 00:20:20,320 --> 00:20:19,250 shot so there you have it and we're 461 00:20:23,260 --> 00:20:20,330 going to be looking forward to doing 462 00:20:25,060 --> 00:20:23,270 more lots more science with the chemcam 463 00:20:27,430 --> 00:20:25,070 instrument but we're excited that it's 464 00:20:28,840 --> 00:20:27,440 looking great so far so I'll turn it 465 00:20:30,640 --> 00:20:28,850 over to joy crisp who's going to talk 466 00:20:33,250 --> 00:20:30,650 more about the overall science status of 467 00:20:34,840 --> 00:20:33,260 the mission thank you so I'm going to go 468 00:20:37,750 --> 00:20:34,850 over some more specifics about what 469 00:20:41,049 --> 00:20:37,760 we've done for science and what's coming 470 00:20:43,870 --> 00:20:41,059 in our science plans the engineering 471 00:20:45,700 --> 00:20:43,880 cameras are now fully checked out and 472 00:20:49,090 --> 00:20:45,710 being used to measure atmospheric dust 473 00:20:51,880 --> 00:20:49,100 winds and clouds we've taken color 474 00:20:54,430 --> 00:20:51,890 images from Mali and mask am we've also 475 00:20:57,909 --> 00:20:54,440 performed thorough check outs on 8 of 476 00:21:00,400 --> 00:20:57,919 our 10 scientific instruments as we've 477 00:21:03,610 --> 00:21:00,410 described in previous press briefings 478 00:21:06,100 --> 00:21:03,620 the the rad radiation monitor the REMS 479 00:21:08,110 --> 00:21:06,110 weather station that Dan neutron 480 00:21:11,049 --> 00:21:08,120 subsurface sounder and chemcam laser 481 00:21:14,020 --> 00:21:11,059 spectrometer and imager are already 482 00:21:15,730 --> 00:21:14,030 taking scientific measurements the Dan 483 00:21:17,919 --> 00:21:15,740 team is busy assessing their first 484 00:21:20,650 --> 00:21:17,929 active measurement that they reported in 485 00:21:22,539 --> 00:21:20,660 the previous press conference chemcam 486 00:21:24,850 --> 00:21:22,549 team is poring over their data as you 487 00:21:27,789 --> 00:21:24,860 heard from Roger and we've got several 488 00:21:30,520 --> 00:21:27,799 days of all day all night weather 489 00:21:32,560 --> 00:21:30,530 readings we're studying and we've 490 00:21:34,900 --> 00:21:32,570 partially checked out the remaining two 491 00:21:39,130 --> 00:21:34,910 instruments our analytical laboratories 492 00:21:42,070 --> 00:21:39,140 Sam and chemin so we're about to go into 493 00:21:45,250 --> 00:21:42,080 this intermission period which we have 494 00:21:48,310 --> 00:21:45,260 three major activities going on in this 495 00:21:50,919 --> 00:21:48,320 period so we'll have two separate days 496 00:21:54,220 --> 00:21:50,929 where we do some Sam atmospheric 497 00:21:56,970 --> 00:21:54,230 checkouts and first time we do that that 498 00:21:59,919 --> 00:21:56,980 will be the first turn on of Sam's pumps 499 00:22:02,649 --> 00:21:59,929 quadrupole mass spectrometer and tunable 500 00:22:06,430 --> 00:22:02,659 laser spectrometer will be very exciting 501 00:22:06,630 --> 00:22:06,440 we will have a campaign to do some of 502 00:22:09,900 --> 00:22:06,640 the 503 00:22:12,990 --> 00:22:09,910 advanced capabilities of mastcam like 504 00:22:16,440 --> 00:22:13,000 the precise focusing over the range that 505 00:22:20,340 --> 00:22:16,450 that it can focus on taking long-range 506 00:22:22,860 --> 00:22:20,350 3d images by positioning the rover at 507 00:22:26,280 --> 00:22:22,870 different parking spots and using those 508 00:22:28,800 --> 00:22:26,290 spots like different I positions to get 509 00:22:31,920 --> 00:22:28,810 the 3d range information and check that 510 00:22:34,380 --> 00:22:31,930 out and and then also thirdly the 511 00:22:36,510 --> 00:22:34,390 chemcam laser spectrometer we're going 512 00:22:38,580 --> 00:22:36,520 to do some more characterization of that 513 00:22:40,440 --> 00:22:38,590 to understand how well the optics are 514 00:22:44,400 --> 00:22:40,450 aligned and how sensitive the 515 00:22:46,470 --> 00:22:44,410 spectrometer is so after the 516 00:22:49,620 --> 00:22:46,480 intermission then we're currently 517 00:22:52,170 --> 00:22:49,630 planning to drive towards glenelg which 518 00:22:53,850 --> 00:22:52,180 is 400 meters to the east that's the 519 00:22:55,980 --> 00:22:53,860 triple Junction that we've shown 520 00:23:00,930 --> 00:22:55,990 pictures of before and we're thinking of 521 00:23:03,990 --> 00:23:00,940 spending a few more days before we start 522 00:23:07,710 --> 00:23:04,000 driving towards that examining the 523 00:23:12,330 --> 00:23:07,720 scours these scours from the sky crane 524 00:23:16,980 --> 00:23:12,340 thrusters using mass cam cam cam and Dan 525 00:23:19,590 --> 00:23:16,990 okay now on the way to glenelg we'd like 526 00:23:23,010 --> 00:23:19,600 to stop as soon as we encounter 527 00:23:25,800 --> 00:23:23,020 scoopable fine material to get going 528 00:23:28,850 --> 00:23:25,810 testing out the sample handling system 529 00:23:32,460 --> 00:23:28,860 and getting sample into Sam and chemin 530 00:23:35,070 --> 00:23:32,470 the first material would be scoopable 531 00:23:37,500 --> 00:23:35,080 fines and we would be trying to clean 532 00:23:40,200 --> 00:23:37,510 out that sample acquisition the scoop 533 00:23:42,510 --> 00:23:40,210 and sample handling system by doing that 534 00:23:44,820 --> 00:23:42,520 several times just tossing it out on the 535 00:23:49,800 --> 00:23:44,830 ground and then taking a sample to put 536 00:23:51,840 --> 00:23:49,810 into Sam and Kim in we might uh likely 537 00:23:54,840 --> 00:23:51,850 hold off on doing our first contact 538 00:23:57,810 --> 00:23:54,850 science with apxs and Molly until we get 539 00:23:59,580 --> 00:23:57,820 to that that area but that is to be 540 00:24:02,160 --> 00:23:59,590 determined we may encounter something 541 00:24:06,240 --> 00:24:02,170 that we want to do that on before we get 542 00:24:11,190 --> 00:24:06,250 there this stop at the scoopable finds 543 00:24:13,350 --> 00:24:11,200 is likely to take a few weeks but so all 544 00:24:16,290 --> 00:24:13,360 of this is it's still fairly uncertain 545 00:24:18,900 --> 00:24:16,300 in terms of the timing when we finally 546 00:24:20,659 --> 00:24:18,910 get to glenelg after doing that we want 547 00:24:23,269 --> 00:24:20,669 to study the outcrop there 548 00:24:25,779 --> 00:24:23,279 and take a look at the contacts between 549 00:24:28,789 --> 00:24:25,789 the three different terrain types and 550 00:24:31,690 --> 00:24:28,799 maybe there is where we would decide to 551 00:24:35,389 --> 00:24:31,700 do our first drilling into rock and 552 00:24:37,549 --> 00:24:35,399 after glenelg we head for Mount sharp 553 00:24:41,119 --> 00:24:37,559 and that will be a much longer drive 554 00:24:45,229 --> 00:24:41,129 with probably some few brief stops along 555 00:24:47,720 --> 00:24:45,239 the way and that that's going to take 556 00:24:50,840 --> 00:24:47,730 several months before we get to that 557 00:24:53,570 --> 00:24:50,850 point that's pretty much sums up what 558 00:24:56,060 --> 00:24:53,580 we've done what we're doing we really 559 00:24:58,430 --> 00:24:56,070 are ramping up from having the initial 560 00:25:00,499 --> 00:24:58,440 checkouts under our belt and now we're 561 00:25:02,779 --> 00:25:00,509 doing very complicated activity plans 562 00:25:05,060 --> 00:25:02,789 each day and working hard on these 563 00:25:06,649 --> 00:25:05,070 strategic plans what the order of 564 00:25:09,049 --> 00:25:06,659 activity should be and how long 565 00:25:12,739 --> 00:25:09,059 everything's going to take so I'll hand 566 00:25:16,220 --> 00:25:12,749 it back to rosemary for QA okay thank 567 00:25:18,200 --> 00:25:16,230 you joy I like to start with a couple of 568 00:25:20,210 --> 00:25:18,210 questions here in the auditorium at JPL 569 00:25:22,159 --> 00:25:20,220 we do have some reporters on the line so 570 00:25:24,289 --> 00:25:22,169 we will get to those as well if you have 571 00:25:27,259 --> 00:25:24,299 a question please raise your hand high 572 00:25:29,840 --> 00:25:27,269 and wait for the mic to get to you and 573 00:25:32,749 --> 00:25:29,850 then identify yourself your name and 574 00:25:34,820 --> 00:25:32,759 your affiliation so do we have a 575 00:25:38,359 --> 00:25:34,830 question yeah let's go in the third row 576 00:25:41,269 --> 00:25:38,369 right here yes Steve Federman from CBS 577 00:25:44,450 --> 00:25:41,279 Pete and matt i guess or anyone wants a 578 00:25:46,999 --> 00:25:44,460 chip comment how significant is this 579 00:25:51,259 --> 00:25:47,009 landmark moment the first drive as short 580 00:25:53,119 --> 00:25:51,269 as it might have been um they couldn't 581 00:25:55,970 --> 00:25:53,129 be more important I mean we build a 582 00:25:58,039 --> 00:25:55,980 rover so unless the rover rose we really 583 00:26:00,080 --> 00:25:58,049 haven't accomplished anything and and so 584 00:26:02,769 --> 00:26:00,090 yes tremendous and and the fact that we 585 00:26:05,419 --> 00:26:02,779 were completely exercised it in 586 00:26:08,659 --> 00:26:05,429 everything was on track is a big moment 587 00:26:10,999 --> 00:26:08,669 very big moment yeah I mean we've got an 588 00:26:13,190 --> 00:26:11,009 amazing team that built this very 589 00:26:14,180 --> 00:26:13,200 capable Rover we had a lot of confidence 590 00:26:15,289 --> 00:26:14,190 that it was going to work but you're 591 00:26:17,659 --> 00:26:15,299 always a little nervous until you get 592 00:26:20,210 --> 00:26:17,669 the data so seeing that you know 593 00:26:21,289 --> 00:26:20,220 everything was nominal as Pete said all 594 00:26:23,989 --> 00:26:21,299 the steer actuators all the drive 595 00:26:25,489 --> 00:26:23,999 actuators work all the instruments you 596 00:26:27,190 --> 00:26:25,499 know the inertial measurement unit that 597 00:26:29,690 --> 00:26:27,200 tells us how we're returning all works 598 00:26:31,489 --> 00:26:29,700 we can now kind of focus on moving to 599 00:26:32,779 --> 00:26:31,499 checking out higher level behaviors for 600 00:26:33,500 --> 00:26:32,789 the rover which will allow us to drive 601 00:26:35,300 --> 00:26:33,510 further every day 602 00:26:37,790 --> 00:26:35,310 a allow us to do kind of autonomous 603 00:26:39,020 --> 00:26:37,800 terrain assessment visual odometry to 604 00:26:42,080 --> 00:26:39,030 more accurately track where the river 605 00:26:43,730 --> 00:26:42,090 goes so we're on pace to having this 606 00:26:45,860 --> 00:26:43,740 amazingly capable rover that can 607 00:26:48,170 --> 00:26:45,870 traverse over to the base of Mount sharp 608 00:26:50,750 --> 00:26:48,180 if I'd like to have just one of the 609 00:26:52,970 --> 00:26:50,760 thing as as you know in the past when 610 00:26:54,500 --> 00:26:52,980 the project got into difficulty one of 611 00:26:55,910 --> 00:26:54,510 the principal double melodies 612 00:26:58,250 --> 00:26:55,920 developmental issues we were working 613 00:27:01,280 --> 00:26:58,260 with with the actuators and I think we 614 00:27:03,680 --> 00:27:01,290 need to recognize the actuator aeroflex 615 00:27:06,020 --> 00:27:03,690 actuator supplier and the actuator team 616 00:27:08,300 --> 00:27:06,030 here at JPL for what has been perfect 617 00:27:10,250 --> 00:27:08,310 performance so far on Mars and it's not 618 00:27:13,670 --> 00:27:10,260 just the drive it's also the arm and the 619 00:27:15,770 --> 00:27:13,680 mast and and the high-gain antenna so so 620 00:27:17,720 --> 00:27:15,780 far they've been just perfect over what 621 00:27:19,040 --> 00:27:17,730 is a very demanding environment so those 622 00:27:21,950 --> 00:27:19,050 that take those people things we 623 00:27:24,890 --> 00:27:21,960 congratulated for that okay do we have 624 00:27:28,010 --> 00:27:24,900 another question here at JPL if so raise 625 00:27:30,140 --> 00:27:28,020 your hand let's go to the phones then we 626 00:27:31,670 --> 00:27:30,150 can always jump back here the first 627 00:27:34,790 --> 00:27:31,680 question on the phone will come from 628 00:27:37,070 --> 00:27:34,800 Eric hand at nature go ahead Eric hi 629 00:27:40,940 --> 00:27:37,080 thanks yeah my questions for joy crisp 630 00:27:44,660 --> 00:27:40,950 hi joy if you could give me a more 631 00:27:48,590 --> 00:27:44,670 specific timeline for the intermission 632 00:27:50,180 --> 00:27:48,600 when I guess in terms of the specifics 633 00:27:52,580 --> 00:27:50,190 all in which the activity would happen 634 00:27:56,870 --> 00:27:52,590 can you say when intermission would 635 00:28:00,320 --> 00:27:56,880 begin when the Sam first Sam atmospheric 636 00:28:05,780 --> 00:28:00,330 study would happen and then when you 637 00:28:07,670 --> 00:28:05,790 might begin the drive take Leonard well 638 00:28:12,020 --> 00:28:07,680 all I can say is we're beginning it 639 00:28:14,720 --> 00:28:12,030 tomorrow and it will span several days 640 00:28:17,980 --> 00:28:14,730 and we can't know exactly what days 641 00:28:20,360 --> 00:28:17,990 we're going to do each thing I believe 642 00:28:24,350 --> 00:28:20,370 that we're going to be trying to do the 643 00:28:26,750 --> 00:28:24,360 first Sam atmospheric tests on Saul 18 644 00:28:29,150 --> 00:28:26,760 but these things are subject to change 645 00:28:34,070 --> 00:28:29,160 as we do the planning things can change 646 00:28:36,020 --> 00:28:34,080 the order in which we do things so the 647 00:28:39,720 --> 00:28:36,030 best answer I can give you is in a 648 00:28:42,450 --> 00:28:39,730 period of a few days 649 00:28:44,990 --> 00:28:42,460 and and like on the order of a week is 650 00:28:49,890 --> 00:28:45,000 what that intermission will will last 651 00:28:51,720 --> 00:28:49,900 and that's the best I can do so on the 652 00:28:54,090 --> 00:28:51,730 order of a week later you might begin 653 00:28:57,570 --> 00:28:54,100 the drive to Leonard on that order and 654 00:29:00,330 --> 00:28:57,580 as a quick follow-up how quickly do you 655 00:29:02,070 --> 00:29:00,340 think you might be able to have a trace 656 00:29:04,860 --> 00:29:02,080 gas result from Sam is that's something 657 00:29:08,580 --> 00:29:04,870 you'll you'll be able to to know in a 658 00:29:10,890 --> 00:29:08,590 day or two the the first atmospheric 659 00:29:13,950 --> 00:29:10,900 measurements done by Sam are really 660 00:29:16,950 --> 00:29:13,960 check out not so much meant to be 661 00:29:20,130 --> 00:29:16,960 definitive measurements so they really 662 00:29:25,020 --> 00:29:20,140 need to to they're not optimized yet for 663 00:29:27,210 --> 00:29:25,030 making good measurements and so you'll 664 00:29:29,010 --> 00:29:27,220 just have to stay tuned for for what 665 00:29:31,020 --> 00:29:29,020 they can say about those measurements 666 00:29:33,450 --> 00:29:31,030 but really they're meant for just the 667 00:29:36,780 --> 00:29:33,460 first checkouts very first one is very 668 00:29:38,460 --> 00:29:36,790 short integration time they they will 669 00:29:41,610 --> 00:29:38,470 learn from those how to set up the 670 00:29:44,730 --> 00:29:41,620 measurements for a very good careful 671 00:29:47,310 --> 00:29:44,740 analysis so it's not possible that you 672 00:29:50,730 --> 00:29:47,320 could maybe see signs of methane in this 673 00:29:54,030 --> 00:29:50,740 first check out I I will leave that to 674 00:29:56,730 --> 00:29:54,040 the San pi/2 report after he sees his 675 00:29:59,310 --> 00:29:56,740 measurements but for now it's it's being 676 00:30:02,520 --> 00:29:59,320 it's it's really meant to be a check out 677 00:30:04,200 --> 00:30:02,530 okay thank you okay we're going to take 678 00:30:07,200 --> 00:30:04,210 another question by phone from the LA 679 00:30:08,550 --> 00:30:07,210 Times Amina kaun hai I think we're 680 00:30:09,630 --> 00:30:08,560 taking my question I just wanted to see 681 00:30:12,810 --> 00:30:09,640 if you could talk a little bit more 682 00:30:14,250 --> 00:30:12,820 about glenelg and the three types of 683 00:30:17,100 --> 00:30:14,260 terrain there you know what do they look 684 00:30:18,600 --> 00:30:17,110 like is it just that layered bedrock 685 00:30:20,040 --> 00:30:18,610 that you guys are looking to drill and 686 00:30:21,660 --> 00:30:20,050 you know before you get there is there 687 00:30:26,250 --> 00:30:21,670 any sort of sense of what the story is 688 00:30:28,620 --> 00:30:26,260 geologically there we have seen very 689 00:30:31,430 --> 00:30:28,630 many interesting cartoons by the science 690 00:30:35,480 --> 00:30:31,440 team trying to look at different 691 00:30:39,630 --> 00:30:35,490 possibilities for what the geologic 692 00:30:43,110 --> 00:30:39,640 situation is there and so they're really 693 00:30:45,590 --> 00:30:43,120 in the hypothesis stage and it's too 694 00:30:49,620 --> 00:30:45,600 early to say what we can see is 695 00:30:51,450 --> 00:30:49,630 different textures to these terrains in 696 00:30:55,049 --> 00:30:51,460 terms of cratering and 697 00:30:58,169 --> 00:30:55,059 looks to them they're albedo's it's it's 698 00:31:01,169 --> 00:30:58,179 it's nearby and it looks like we should 699 00:31:03,570 --> 00:31:01,179 be able to encounter bedrock there so 700 00:31:05,940 --> 00:31:03,580 the that's that's a really good reason 701 00:31:09,690 --> 00:31:05,950 for going there is is to be able to 702 00:31:12,120 --> 00:31:09,700 examine three different materials that 703 00:31:16,380 --> 00:31:12,130 are in place that look like we could 704 00:31:20,070 --> 00:31:16,390 sample rock not much more I can say 705 00:31:21,870 --> 00:31:20,080 about it at this point but that it does 706 00:31:26,899 --> 00:31:21,880 look intriguing I don't know if anybody 707 00:31:31,620 --> 00:31:29,070 okay well then let's take our next 708 00:31:34,830 --> 00:31:31,630 question again by phone that's Irene 709 00:31:37,710 --> 00:31:34,840 Klotz from Reuters hi thanks very much 710 00:31:39,960 --> 00:31:37,720 ever just one quick follow-up about the 711 00:31:43,110 --> 00:31:39,970 drive just wanted to know if indeed it 712 00:31:46,049 --> 00:31:43,120 took 30 minutes as we were told 713 00:31:48,330 --> 00:31:46,059 yesterday that that would be the likely 714 00:31:51,779 --> 00:31:48,340 duration of it and then I have a couple 715 00:31:54,659 --> 00:31:51,789 questions about cam cam thanks so the 716 00:31:58,139 --> 00:31:54,669 drive started local solar time at 1332 717 00:32:00,840 --> 00:31:58,149 which was 717 am here pacific daylight 718 00:32:03,330 --> 00:32:00,850 time and with all the imaging it took 719 00:32:06,419 --> 00:32:03,340 roughly 16 minutes and the majority of 720 00:32:08,490 --> 00:32:06,429 that time is spent taking the images the 721 00:32:14,159 --> 00:32:08,500 rover actually probably only drove for 722 00:32:17,370 --> 00:32:14,169 45 minutes of that motion and that for 723 00:32:18,960 --> 00:32:17,380 Roger the one of the things I think you 724 00:32:21,240 --> 00:32:18,970 all have talked about earlier with chem 725 00:32:24,990 --> 00:32:21,250 can as you are curious if you were going 726 00:32:27,419 --> 00:32:25,000 to see different spectra as you as you 727 00:32:29,720 --> 00:32:27,429 pulse deeper into the rock and was 728 00:32:33,019 --> 00:32:29,730 wondering if you did see any composition 729 00:32:34,769 --> 00:32:33,029 changes and then I think I might have 730 00:32:36,870 --> 00:32:34,779 wasn't sure about this but his 731 00:32:38,460 --> 00:32:36,880 coronation actually at the Goulburn 732 00:32:42,120 --> 00:32:38,470 scour or was that in a different 733 00:32:43,830 --> 00:32:42,130 location thanks um no I'll answer your 734 00:32:46,560 --> 00:32:43,840 first question or your last question 735 00:32:50,130 --> 00:32:46,570 first coronation was not a part of the 736 00:32:52,440 --> 00:32:50,140 Goulburn scour it was just sort of ahead 737 00:32:54,180 --> 00:32:52,450 of and a little bit to the right of the 738 00:32:56,669 --> 00:32:54,190 rover where it was sitting when it 739 00:32:59,879 --> 00:32:56,679 landed the Goulburn scour was off to the 740 00:33:02,010 --> 00:32:59,889 left and so if you look back at image at 741 00:33:04,440 --> 00:33:02,020 the image of coronation you'll actually 742 00:33:05,790 --> 00:33:04,450 see the rover's shadow in it 743 00:33:09,540 --> 00:33:05,800 and that's sort of looking to the 744 00:33:11,850 --> 00:33:09,550 forward side of the rover so let's see 745 00:33:13,680 --> 00:33:11,860 the other was about asking whether we 746 00:33:16,680 --> 00:33:13,690 were seeing differences in the spectra 747 00:33:19,740 --> 00:33:16,690 as we as we dug down into the rock so 748 00:33:23,130 --> 00:33:19,750 the the little inset of the spectrum did 749 00:33:25,530 --> 00:33:23,140 show the hydrogen at the very surface so 750 00:33:27,570 --> 00:33:25,540 of course the surface is one thing we 751 00:33:31,620 --> 00:33:27,580 were interested in and we'll be looking 752 00:33:33,300 --> 00:33:31,630 into that further there there was a hint 753 00:33:36,120 --> 00:33:33,310 of some other variations and one other 754 00:33:38,430 --> 00:33:36,130 measurement we made but this can be say 755 00:33:40,620 --> 00:33:38,440 a transition between looking at one 756 00:33:43,860 --> 00:33:40,630 mineral grain to another so we have to 757 00:33:46,500 --> 00:33:43,870 look at that a little bit more okay 758 00:33:48,180 --> 00:33:46,510 before we before we go back to another 759 00:33:50,730 --> 00:33:48,190 phone question just want to make sure 760 00:33:52,620 --> 00:33:50,740 anybody reporters here at JPL who have a 761 00:33:54,420 --> 00:33:52,630 question just go ahead and raise your 762 00:33:56,040 --> 00:33:54,430 hand and we will get to you but in the 763 00:33:59,580 --> 00:33:56,050 meantime let's take a phone question 764 00:34:01,380 --> 00:33:59,590 from Leo and right at irish TV thanks 765 00:34:03,720 --> 00:34:01,390 very much Jane there just a quick 766 00:34:06,450 --> 00:34:03,730 question about coronation and the 767 00:34:08,910 --> 00:34:06,460 spectra you said that is it a basaltic 768 00:34:12,150 --> 00:34:08,920 composition so I mean what do you say 769 00:34:15,240 --> 00:34:12,160 you think this is Bassel Jim but not as 770 00:34:17,040 --> 00:34:15,250 we know it or is this the standard bath 771 00:34:18,930 --> 00:34:17,050 salt and can you make any comparison 772 00:34:21,240 --> 00:34:18,940 with you know where on earth you might 773 00:34:23,250 --> 00:34:21,250 find similar bath salts given that you 774 00:34:26,550 --> 00:34:23,260 seem to know so much about this already 775 00:34:29,580 --> 00:34:26,560 thanks to this instrument yeah thanks 776 00:34:34,470 --> 00:34:29,590 we're still working on the calibrations 777 00:34:36,720 --> 00:34:34,480 in a big way yet on on cam cam we have a 778 00:34:38,160 --> 00:34:36,730 number of different types of calibration 779 00:34:41,900 --> 00:34:38,170 we have to do first of all wavelength 780 00:34:44,670 --> 00:34:41,910 calibration this is much this this 781 00:34:46,320 --> 00:34:44,680 spectrometer has much higher sensitivity 782 00:34:48,900 --> 00:34:46,330 to the wavelength than anything that 783 00:34:50,820 --> 00:34:48,910 we've we've used in this spectral region 784 00:34:53,370 --> 00:34:50,830 before and so we're working to make sure 785 00:34:55,290 --> 00:34:53,380 that that is characterized I mean the 786 00:34:57,240 --> 00:34:55,300 wavelength shifts just a little bit when 787 00:34:59,190 --> 00:34:57,250 when the rover changes temperature just 788 00:35:02,130 --> 00:34:59,200 slightly during a day and so we're 789 00:35:04,950 --> 00:35:02,140 working on that we also have a spectral 790 00:35:06,860 --> 00:35:04,960 library that we built up back here 791 00:35:09,900 --> 00:35:06,870 before we sent the instrument off and 792 00:35:11,180 --> 00:35:09,910 and so we have those to compare with but 793 00:35:14,190 --> 00:35:11,190 right now all we're doing is looking 794 00:35:16,790 --> 00:35:14,200 qualitatively at that spectrum and sort 795 00:35:18,089 --> 00:35:16,800 of you know matching it up against a 796 00:35:20,039 --> 00:35:18,099 spectrum 797 00:35:21,719 --> 00:35:20,049 that we have from the laboratory and it 798 00:35:23,789 --> 00:35:21,729 just looks like some of the basalts 799 00:35:26,489 --> 00:35:23,799 we're going to get into the quantitative 800 00:35:29,370 --> 00:35:26,499 aspects in a little bit but I also want 801 00:35:32,579 --> 00:35:29,380 to say that that chemcam is is a bit 802 00:35:34,979 --> 00:35:32,589 less quantitative actually then then the 803 00:35:37,440 --> 00:35:34,989 apxs instrument on board for many 804 00:35:40,380 --> 00:35:37,450 elements and so we're also looking 805 00:35:42,479 --> 00:35:40,390 forward to when apxs gets deployed on 806 00:35:44,460 --> 00:35:42,489 the arm and when we can make some cross 807 00:35:46,650 --> 00:35:44,470 calibrations which will make us more 808 00:35:48,450 --> 00:35:46,660 certain of our of our compositions as 809 00:35:51,779 --> 00:35:48,460 well these two instruments really 810 00:35:53,880 --> 00:35:51,789 complement each other very well chemcam 811 00:35:57,599 --> 00:35:53,890 gets some elements very sensitively that 812 00:35:59,519 --> 00:35:57,609 apxs didn't does not an apxs tends to 813 00:36:04,769 --> 00:35:59,529 have more accuracy overall than chemcam 814 00:36:06,120 --> 00:36:04,779 so it's a great duo to have our next 815 00:36:16,499 --> 00:36:06,130 question is going to come from ken 816 00:36:18,269 --> 00:36:16,509 kremer @ Space Flight magazine hello ken 817 00:36:21,989 --> 00:36:18,279 are you still there so you can go ahead 818 00:36:24,319 --> 00:36:21,999 and ask your question ok I guess yeah 819 00:36:26,940 --> 00:36:24,329 we'll come back to can if he reappears 820 00:36:29,299 --> 00:36:26,950 the next question is going to come from 821 00:36:34,049 --> 00:36:29,309 Robert Perlman at collectspace.com 822 00:36:38,579 --> 00:36:34,059 Robert you there I am looking at the 823 00:36:43,529 --> 00:36:38,589 track can you quantify how deep or how 824 00:36:45,509 --> 00:36:43,539 shallow the the track marks are and if 825 00:36:47,130 --> 00:36:45,519 for example if a good windstorm came by 826 00:36:48,479 --> 00:36:47,140 would they just be blown away or what 827 00:36:51,359 --> 00:36:48,489 does that tell you about the nature of 828 00:36:54,120 --> 00:36:51,369 the land that you landed on I have a 829 00:36:56,249 --> 00:36:54,130 follow I can answer maybe just how deep 830 00:36:58,380 --> 00:36:56,259 we sink so we've got the cleats which 831 00:37:01,049 --> 00:36:58,390 are about a centimeter or so tall and 832 00:37:02,549 --> 00:37:01,059 what happens is we dig into the terrain 833 00:37:03,989 --> 00:37:02,559 with the cleats and then the ground 834 00:37:05,880 --> 00:37:03,999 pressure is absorbed by the rest of the 835 00:37:07,709 --> 00:37:05,890 wheel and we don't see much sinkage 836 00:37:09,029 --> 00:37:07,719 beyond that where if you were driving on 837 00:37:11,670 --> 00:37:09,039 really soft sand you would see 838 00:37:13,829 --> 00:37:11,680 significantly more sinkage so we can 839 00:37:16,049 --> 00:37:13,839 tell just from the properties of looking 840 00:37:18,450 --> 00:37:16,059 at these tracks kind of how firm the 841 00:37:19,799 --> 00:37:18,460 soil is but I don't think I can 842 00:37:21,359 --> 00:37:19,809 necessarily answer a question about the 843 00:37:26,180 --> 00:37:21,369 dust and how they might get covered up 844 00:37:29,150 --> 00:37:26,190 maybe joy depend on what the winds do 845 00:37:30,530 --> 00:37:29,160 and whether there's fine material that 846 00:37:34,340 --> 00:37:30,540 will get deposited on these tracks or 847 00:37:36,980 --> 00:37:34,350 not i think if i'm not mistaken it's the 848 00:37:40,550 --> 00:37:36,990 tracks should be somewhat similar in 849 00:37:41,780 --> 00:37:40,560 depth to mur tracks so there still could 850 00:37:43,700 --> 00:37:41,790 be a difference in the material 851 00:37:46,880 --> 00:37:43,710 properties here but if you treat them as 852 00:37:50,450 --> 00:37:46,890 murder tracks then there were times it 853 00:37:52,820 --> 00:37:50,460 took a little when the tracks would get 854 00:37:55,910 --> 00:37:52,830 covered and doesn't start to disappear 855 00:37:58,970 --> 00:37:55,920 so I don't expect that this would happen 856 00:38:01,310 --> 00:37:58,980 rapidly but maybe after many months or 857 00:38:05,900 --> 00:38:01,320 years get harder and harder to see these 858 00:38:08,450 --> 00:38:05,910 tracks I think and just a quick 859 00:38:12,010 --> 00:38:08,460 follow-up with regards to Bradbury 860 00:38:14,210 --> 00:38:12,020 landing is it defined by the borders of 861 00:38:15,980 --> 00:38:14,220 curiosities wheels where it's set where 862 00:38:18,530 --> 00:38:15,990 it landed or it does it accomplish this 863 00:38:20,900 --> 00:38:18,540 whole area where you're now even sitting 864 00:38:23,240 --> 00:38:20,910 now well we're actually thinking of 865 00:38:29,050 --> 00:38:23,250 using the the wheel marks as the corner 866 00:38:31,790 --> 00:38:29,060 posts for Bradbury landing a great thing 867 00:38:33,950 --> 00:38:31,800 i'm told that ken Kramer of spaceflight 868 00:38:36,830 --> 00:38:33,960 magazine has reappeared so go ahead Ken 869 00:38:39,530 --> 00:38:36,840 okay I here can you hear me I hope we 870 00:38:41,900 --> 00:38:39,540 didn't get disconnected again my 871 00:38:44,480 --> 00:38:41,910 question is for Roger Weems I wonder if 872 00:38:47,060 --> 00:38:44,490 you could talk about how many targets in 873 00:38:49,520 --> 00:38:47,070 a day can you can you analyze with with 874 00:38:51,380 --> 00:38:49,530 chemcam I understand it's 14,000 overall 875 00:38:55,100 --> 00:38:51,390 but almost wondering in a day how many 876 00:38:58,010 --> 00:38:55,110 can can you analyze yes that 14,000 877 00:38:59,960 --> 00:38:58,020 number can came from looking at the 878 00:39:02,090 --> 00:38:59,970 number of days or Sol's that were going 879 00:39:05,750 --> 00:39:02,100 to be on Mars in the nominal mission 880 00:39:08,570 --> 00:39:05,760 which is 700 some and and assuming that 881 00:39:11,810 --> 00:39:08,580 a maximum that we would possibly do 882 00:39:13,970 --> 00:39:11,820 would be 20 analyses per day and so 883 00:39:16,340 --> 00:39:13,980 that's how we came up with that now it's 884 00:39:18,860 --> 00:39:16,350 going to be a long time or it could be a 885 00:39:22,160 --> 00:39:18,870 while anyway before we are we get to do 886 00:39:24,260 --> 00:39:22,170 20 analyses in one day but if we arrive 887 00:39:26,750 --> 00:39:24,270 at a new site after driving some 888 00:39:29,570 --> 00:39:26,760 distance and you can imagine an outcrop 889 00:39:31,460 --> 00:39:29,580 in front of us we could perhaps target 890 00:39:34,940 --> 00:39:31,470 something close to that it really 891 00:39:36,740 --> 00:39:34,950 depends how how crafty and how skillful 892 00:39:39,240 --> 00:39:36,750 some of our uplink people get and 893 00:39:40,950 --> 00:39:39,250 devising these sequences 894 00:39:44,850 --> 00:39:40,960 and they're coming up to speed very 895 00:39:47,400 --> 00:39:44,860 nicely okay I was willing to act after 896 00:39:49,830 --> 00:39:47,410 you get the data how quickly are you 897 00:39:52,740 --> 00:39:49,840 able to analyze it and decide you know 898 00:39:55,170 --> 00:39:52,750 what what you're seeing yeah so the 899 00:39:58,830 --> 00:39:55,180 process once the once the information 900 00:40:01,920 --> 00:39:58,840 comes down we have a role called a 901 00:40:05,520 --> 00:40:01,930 payload downlink lead and so that person 902 00:40:08,730 --> 00:40:05,530 is responsible on our chemcam team for 903 00:40:12,120 --> 00:40:08,740 pulling the data over onto a computer 904 00:40:14,640 --> 00:40:12,130 and starting to first of all check out 905 00:40:18,930 --> 00:40:14,650 what files did we receive and then 906 00:40:20,760 --> 00:40:18,940 secondly are they looking okay and so we 907 00:40:22,290 --> 00:40:20,770 look at the images that we received and 908 00:40:24,690 --> 00:40:22,300 we look at the spectra that we received 909 00:40:27,600 --> 00:40:24,700 and we look at other things such as we 910 00:40:29,280 --> 00:40:27,610 usually usually take a non laser dark 911 00:40:31,290 --> 00:40:29,290 spectrum as well to subtract the 912 00:40:34,470 --> 00:40:31,300 background all of those things get 913 00:40:37,320 --> 00:40:34,480 pulled together and then within within 914 00:40:41,220 --> 00:40:37,330 about a couple of hours they've usually 915 00:40:45,000 --> 00:40:41,230 gone through and catalogued what we've 916 00:40:46,650 --> 00:40:45,010 seen and we get ready to present that at 917 00:40:48,840 --> 00:40:46,660 a science kickoff meeting with in about 918 00:40:50,910 --> 00:40:48,850 two hours of the downlink and then we 919 00:40:54,420 --> 00:40:50,920 usually do more analysis after that but 920 00:40:56,670 --> 00:40:54,430 that's the initial thank you we're going 921 00:40:59,040 --> 00:40:56,680 to take a question now from space calm 922 00:41:02,190 --> 00:40:59,050 and mike wall and i see we do have a 923 00:41:03,900 --> 00:41:02,200 question after that from JPL go ahead 924 00:41:07,110 --> 00:41:03,910 Mike yeah oh yeah hi this one's probably 925 00:41:09,150 --> 00:41:07,120 for format do you guys have any idea I 926 00:41:10,650 --> 00:41:09,160 mean once you guys start start to 927 00:41:12,870 --> 00:41:10,660 actually drive made your first big 928 00:41:14,130 --> 00:41:12,880 drives I mean how how long are those 929 00:41:18,750 --> 00:41:14,140 first drive is going to be when you 930 00:41:20,190 --> 00:41:18,760 finally head out from from the yeah like 931 00:41:22,380 --> 00:41:20,200 the like sort of landing site where you 932 00:41:24,300 --> 00:41:22,390 are now and and like head toward your 933 00:41:26,010 --> 00:41:24,310 first big science target like there's 934 00:41:28,110 --> 00:41:26,020 going to be 10 to 20 meters like I've 935 00:41:29,700 --> 00:41:28,120 heard before you guys like have a little 936 00:41:33,360 --> 00:41:29,710 more confidence now that like maybe can 937 00:41:35,130 --> 00:41:33,370 mix them and a longer drive that's a 938 00:41:37,620 --> 00:41:35,140 good question Mike so we'll start out 939 00:41:39,360 --> 00:41:37,630 with fairly modest drives in a 10 meter 940 00:41:40,620 --> 00:41:39,370 range and then as I mentioned before 941 00:41:43,200 --> 00:41:40,630 we're going to do a couple checkouts 942 00:41:45,330 --> 00:41:43,210 we're going to check out the autonomous 943 00:41:47,610 --> 00:41:45,340 ability of the rover to image obstacles 944 00:41:49,860 --> 00:41:47,620 and identify hazards so that it doesn't 945 00:41:51,240 --> 00:41:49,870 you know it keeps itself safe we'll 946 00:41:52,710 --> 00:41:51,250 check out visual odometry where the 947 00:41:53,100 --> 00:41:52,720 rover takes a couple of images and is 948 00:41:55,110 --> 00:41:53,110 able to 949 00:41:56,910 --> 00:41:55,120 how far it moves so we can see if we're 950 00:41:58,590 --> 00:41:56,920 slipping and abetting in the in the 951 00:42:00,720 --> 00:41:58,600 terrain and we're doing that on Mars 952 00:42:02,550 --> 00:42:00,730 because we've never done that image 953 00:42:04,020 --> 00:42:02,560 processing on board the software using 954 00:42:05,280 --> 00:42:04,030 images coming from Mars it's different 955 00:42:06,270 --> 00:42:05,290 lighting it's different terrain so we 956 00:42:08,460 --> 00:42:06,280 just want to make sure it's all working 957 00:42:09,930 --> 00:42:08,470 as we expect once we get that 958 00:42:11,250 --> 00:42:09,940 functionality checked out and we have 959 00:42:13,320 --> 00:42:11,260 confidence in it will start expanding 960 00:42:16,980 --> 00:42:13,330 the drive distances will go to 20 meters 961 00:42:18,930 --> 00:42:16,990 30 meters 40 meters and 40 meters is 962 00:42:20,250 --> 00:42:18,940 kind of the edge of our nav cam horizon 963 00:42:22,710 --> 00:42:20,260 that we can see right now that's where 964 00:42:24,930 --> 00:42:22,720 we get good stereo data with these nav 965 00:42:26,880 --> 00:42:24,940 cams that we're taking and then as we 966 00:42:28,200 --> 00:42:26,890 continue to have more and more 967 00:42:29,430 --> 00:42:28,210 confidence in the system will extend 968 00:42:32,760 --> 00:42:29,440 those drives and will start driving 969 00:42:34,140 --> 00:42:32,770 beyond that nav cam horizon out 50 even 970 00:42:38,310 --> 00:42:34,150 up to a potentially hundred meters or so 971 00:42:40,980 --> 00:42:38,320 poor persol we're going to jump back to 972 00:42:42,300 --> 00:42:40,990 JPL we have a question from women in the 973 00:42:45,690 --> 00:42:42,310 row there please state your name and 974 00:42:47,970 --> 00:42:45,700 affiliation Amy Johnson kcbs-tv I think 975 00:42:50,070 --> 00:42:47,980 my question is for Matt and looking at 976 00:42:51,900 --> 00:42:50,080 the screen here this photo I I can 977 00:42:53,670 --> 00:42:51,910 clearly make out the tracks but can you 978 00:42:56,700 --> 00:42:53,680 explain a little bit more about what 979 00:42:59,670 --> 00:42:56,710 we're actually seeing in this photo yes 980 00:43:01,260 --> 00:42:59,680 so this is a very historic photo there's 981 00:43:03,420 --> 00:43:01,270 only one place on Mars where you start 982 00:43:04,980 --> 00:43:03,430 your tracks and you can see exactly 983 00:43:07,260 --> 00:43:04,990 where we landed because you can see the 984 00:43:08,970 --> 00:43:07,270 tracks where we're starting and then to 985 00:43:11,040 --> 00:43:08,980 the right of the tracks you can see kind 986 00:43:13,290 --> 00:43:11,050 of two dark spots those are the scour 987 00:43:15,270 --> 00:43:13,300 marks form from the landing engines and 988 00:43:17,700 --> 00:43:15,280 then similar you see them symmetrically 989 00:43:19,350 --> 00:43:17,710 on the other side the two left marks and 990 00:43:21,360 --> 00:43:19,360 then you can see the tracks how we drive 991 00:43:23,460 --> 00:43:21,370 forward and then you can see roughly a 992 00:43:25,170 --> 00:43:23,470 circle which is where the rover did what 993 00:43:27,180 --> 00:43:25,180 we call its turn in place maneuver so it 994 00:43:30,210 --> 00:43:27,190 steered all of its wheels and then it 995 00:43:31,470 --> 00:43:30,220 performed a turn of 120 degrees pivoting 996 00:43:34,260 --> 00:43:31,480 about that point in the middle of that 997 00:43:35,700 --> 00:43:34,270 circle and then it backed up one of the 998 00:43:37,890 --> 00:43:35,710 other things that we can point out in 999 00:43:40,260 --> 00:43:37,900 here is that we see different patterns 1000 00:43:42,360 --> 00:43:40,270 in the wheels we have intentionally put 1001 00:43:44,070 --> 00:43:42,370 holes in the wheels to leave a unique 1002 00:43:46,470 --> 00:43:44,080 track on Mars that we can use for that 1003 00:43:47,940 --> 00:43:46,480 visual odometry where we can for in sand 1004 00:43:49,560 --> 00:43:47,950 dunes where we don't have lots of rock 1005 00:43:52,520 --> 00:43:49,570 features around us we can use those 1006 00:43:54,780 --> 00:43:52,530 patterns to to do our visual odometry 1007 00:43:56,760 --> 00:43:54,790 the other thing to note in here is 1008 00:43:59,190 --> 00:43:56,770 there's a small rock under where we 1009 00:44:00,750 --> 00:43:59,200 landed on the right rear wheel and when 1010 00:44:03,180 --> 00:44:00,760 we did our steer actuator check out we 1011 00:44:04,530 --> 00:44:03,190 saw some somewhat high currents and you 1012 00:44:06,120 --> 00:44:04,540 can actually see in the animation that 1013 00:44:06,480 --> 00:44:06,130 the bogie the suspension system at the 1014 00:44:08,400 --> 00:44:06,490 back of 1015 00:44:10,470 --> 00:44:08,410 Rover kind of tweaks out to the to the 1016 00:44:12,960 --> 00:44:10,480 right a little bit and we were able to 1017 00:44:15,390 --> 00:44:12,970 confirm that we were kind of on that 1018 00:44:17,250 --> 00:44:15,400 nine centimeter tall rock when we landed 1019 00:44:18,630 --> 00:44:17,260 down so this is great we're able to see 1020 00:44:20,100 --> 00:44:18,640 under the rover see exactly what we 1021 00:44:22,410 --> 00:44:20,110 landed on and kind of correlate that to 1022 00:44:25,500 --> 00:44:22,420 the engineering we data we got from the 1023 00:44:27,800 --> 00:44:25,510 Saul 15 steer actuator check out that 1024 00:44:30,750 --> 00:44:27,810 answer your question it did thank you 1025 00:44:33,630 --> 00:44:30,760 okay that oh it looks like we have what 1026 00:44:35,220 --> 00:44:33,640 time for one more question go ahead nice 1027 00:44:39,090 --> 00:44:35,230 ending question the you present of the 1028 00:44:41,040 --> 00:44:39,100 United States of lauded JPL and ms dr. 1029 00:44:42,210 --> 00:44:41,050 elachi the Governor of California is 1030 00:44:44,220 --> 00:44:42,220 going to be here today Michael if you 1031 00:44:46,859 --> 00:44:44,230 wouldn't mind everything seems to have 1032 00:44:49,890 --> 00:44:46,869 been working perfectly up till now it is 1033 00:44:51,930 --> 00:44:49,900 it seems to be textbook give us an 1034 00:44:55,410 --> 00:44:51,940 assessment several weeks into this now 1035 00:44:57,060 --> 00:44:55,420 as to how your team is working your soul 1036 00:44:59,790 --> 00:44:57,070 is a different day than the one that 1037 00:45:01,050 --> 00:44:59,800 we're used to and and what what the 1038 00:45:03,000 --> 00:45:01,060 attitude is like now that you've 1039 00:45:05,580 --> 00:45:03,010 captured the nation's attention and the 1040 00:45:09,870 --> 00:45:05,590 imagination of so many with this with 1041 00:45:12,390 --> 00:45:09,880 this Rover the team is tremendously 1042 00:45:14,580 --> 00:45:12,400 excited everything's working there the 1043 00:45:16,070 --> 00:45:14,590 we've kind of gone through starting in 1044 00:45:18,570 --> 00:45:16,080 the middle of the night going through 1045 00:45:19,590 --> 00:45:18,580 daylight and and actually over the next 1046 00:45:21,900 --> 00:45:19,600 couple of weeks we're going to move back 1047 00:45:23,400 --> 00:45:21,910 to being on the night shift as you know 1048 00:45:27,330 --> 00:45:23,410 the difference between Earth Day and 1049 00:45:31,230 --> 00:45:27,340 marsall shifts out of you know from day 1050 00:45:35,340 --> 00:45:31,240 to day night but everything's working 1051 00:45:36,810 --> 00:45:35,350 the the hard part is kind of damn 1052 00:45:38,640 --> 00:45:36,820 purring the excitement a little bit so 1053 00:45:41,160 --> 00:45:38,650 that people get enough rest so that they 1054 00:45:44,550 --> 00:45:41,170 are in it for the long haul instead of 1055 00:45:46,349 --> 00:45:44,560 just just waiting anxiously for each 1056 00:45:49,470 --> 00:45:46,359 image to come down but it is fantastic 1057 00:45:52,680 --> 00:45:49,480 how well everything is working and so 1058 00:45:54,450 --> 00:45:52,690 everything that we've promised with with 1059 00:45:55,890 --> 00:45:54,460 this Rover going to Mars and going to 1060 00:45:58,200 --> 00:45:55,900 place where we think is interacted with 1061 00:45:59,849 --> 00:45:58,210 water I we have high hopes that this is 1062 00:46:01,880 --> 00:45:59,859 going to really prove out this region 1063 00:46:05,730 --> 00:46:01,890 and tell us whether or not it was ever 1064 00:46:07,800 --> 00:46:05,740 potentially habitable and I wouldn't be 1065 00:46:09,780 --> 00:46:07,810 doing my job if I didn't exercise a 1066 00:46:13,200 --> 00:46:09,790 little bit of caution here 1067 00:46:16,380 --> 00:46:13,210 ok we are 16 days into a two-year 1068 00:46:20,400 --> 00:46:16,390 mission ok we haven't put the grout the 1069 00:46:22,170 --> 00:46:20,410 arm on the ground yet ok there's a we 1070 00:46:24,140 --> 00:46:22,180 haven't exercised a sample gathering 1071 00:46:27,060 --> 00:46:24,150 capability which is a key key key 1072 00:46:29,340 --> 00:46:27,070 element of this Rover science mission so 1073 00:46:33,030 --> 00:46:29,350 as good as its gon and as wonderful as 1074 00:46:34,560 --> 00:46:33,040 it is you know we still only checked off 1075 00:46:39,180 --> 00:46:34,570 about two of the level one requirement 1076 00:46:41,700 --> 00:46:39,190 boxes launched on time land on Mars ok 1077 00:46:43,890 --> 00:46:41,710 and and we got a long way to go before 1078 00:46:46,620 --> 00:46:43,900 this mission reached its full its full 1079 00:46:48,930 --> 00:46:46,630 potential but but the fact we haven't 1080 00:46:54,270 --> 00:46:48,940 had any early problem is is in fact 1081 00:46:57,720 --> 00:46:54,280 fantastic but I just you know managing 1082 00:46:59,520 --> 00:46:57,730 expectations right you know and and we 1083 00:47:02,040 --> 00:46:59,530 got to keep doing this as the team has 1084 00:47:04,380 --> 00:47:02,050 been doing methodically properly 1085 00:47:06,300 --> 00:47:04,390 prudently so as not to get out of 1086 00:47:10,320 --> 00:47:06,310 ourselves and cause ourselves our own 1087 00:47:12,750 --> 00:47:10,330 headache so but as as Michael said so 1088 00:47:17,160 --> 00:47:12,760 far it's been wonderful science 1089 00:47:21,540 --> 00:47:17,170 engineering enthusiasm caution what more 1090 00:47:24,210 --> 00:47:21,550 we connect all right well that wraps up 1091 00:47:26,190 --> 00:47:24,220 the Q&A portion and thank you to our 1092 00:47:27,840 --> 00:47:26,200 panelists immediately after this we will 1093 00:47:29,580 --> 00:47:27,850 replay the visuals from the news 1094 00:47:32,780 --> 00:47:29,590 conference and remember a lot of 1095 00:47:38,550 --> 00:47:32,790 informations online and images 24-7 at 1096 00:47:42,090 --> 00:47:38,560 WWDC gov / MSL however in closing we do 1097 00:47:44,550 --> 00:47:42,100 have a short video clip from 2009 when 1098 00:47:46,590 --> 00:47:44,560 Ray Bradbury visited JPL and he was 1099 00:47:49,110 --> 00:47:46,600 right here in this von karman auditorium 1100 00:47:52,050 --> 00:47:49,120 he was here to congratulate the team on 1101 00:47:55,590 --> 00:47:52,060 the fifth anniversary of the twin Mars 1102 00:47:58,260 --> 00:47:55,600 rovers spirit and opportunity and some 1103 00:47:59,760 --> 00:47:58,270 of the rover drivers they were very 1104 00:48:02,490 --> 00:47:59,770 excited to meet him and wanted to 1105 00:48:05,400 --> 00:48:02,500 express their gratitude to him for 1106 00:48:07,740 --> 00:48:05,410 inspiring them so we have a very short 1107 00:48:12,100 --> 00:48:07,750 video remembrance of that day to share 1108 00:48:35,070 --> 00:48:18,240 you 1109 00:48:40,060 --> 00:48:37,630 having Ray Bradbury here was incredible 1110 00:48:42,370 --> 00:48:40,070 because in particular from Mars he 1111 00:48:45,550 --> 00:48:42,380 really has been one of the voices from 1112 00:48:48,370 --> 00:48:45,560 very very early on for going to Mars and 1113 00:48:51,190 --> 00:48:48,380 exploring Mars long before we knew how 1114 00:48:52,990 --> 00:48:51,200 to do it he was taking us there in our 1115 00:48:54,730 --> 00:48:53,000 minds he introduce you to some of the 1116 00:48:57,550 --> 00:48:54,740 other people to drive the rover with me 1117 00:49:00,400 --> 00:48:57,560 yes sir so our Rovers well just like 1118 00:49:04,360 --> 00:49:00,410 this when he came to the operations room 1119 00:49:07,330 --> 00:49:04,370 and we showed him that the model of the 1120 00:49:09,070 --> 00:49:07,340 rover and the the large-scale panoramic 1121 00:49:12,090 --> 00:49:09,080 pictures that we've taken the actual 1122 00:49:14,890 --> 00:49:12,100 photographs of the surface of the planet 1123 00:49:17,260 --> 00:49:14,900 it was like watching him experience it 1124 00:49:19,060 --> 00:49:17,270 as a child almost would experience it 1125 00:49:22,120 --> 00:49:19,070 just the wonderment he has never lost 1126 00:49:24,190 --> 00:49:22,130 that wonder for Mars that he's always 1127 00:49:25,750 --> 00:49:24,200 conveyed in his books there you go we're 1128 00:49:27,790 --> 00:49:25,760 getting a vit already we're gonna have 1129 00:49:29,980 --> 00:49:27,800 to hire you showing him how we control 1130 00:49:31,990 --> 00:49:29,990 the rover and using the simulator and 1131 00:49:33,880 --> 00:49:32,000 letting him we basically drive for 1132 00:49:36,310 --> 00:49:33,890 simulated over across the surface of the 1133 00:49:38,530 --> 00:49:36,320 planet and letting him see the reality 1134 00:49:40,990 --> 00:49:38,540 of that was very rewarding for us 1135 00:49:44,470 --> 00:49:41,000 because we could tell how how much it 1136 00:49:46,870 --> 00:49:44,480 meant to him to see this that once that 1137 00:49:50,320 --> 00:49:46,880 was only fiction that partly because of 1138 00:49:52,630 --> 00:49:50,330 his vision and his sharing that vision
