1 00:00:16,090 --> 00:00:13,019 Johnson Space Center in Houston Texas 2 00:00:18,519 --> 00:00:16,100 thanks - on today's hangout I'm Brandi 3 00:00:20,339 --> 00:00:18,529 Jean with NASA public affairs and we're 4 00:00:24,849 --> 00:00:20,349 about 30 minutes away now from the most 5 00:00:26,230 --> 00:00:24,859 of orion's been delayed a bit this 6 00:00:27,669 --> 00:00:26,240 morning thanks to some issues with the 7 00:00:29,710 --> 00:00:27,679 support aircraft but we should be able 8 00:00:31,329 --> 00:00:29,720 to see the drop live at about noon 9 00:00:32,799 --> 00:00:31,339 eastern time here in just a few minutes 10 00:00:34,389 --> 00:00:32,809 and in the meantime we're gonna be 11 00:00:37,689 --> 00:00:34,399 taking your questions from social media 12 00:00:40,420 --> 00:00:37,699 under the hashtag Orion test so start 13 00:00:41,849 --> 00:00:40,430 sending those in now I'm sitting here in 14 00:00:44,319 --> 00:00:41,859 front of a mock-up of NASA's new Orion 15 00:00:45,610 --> 00:00:44,329 spacecraft which we're building to take 16 00:00:47,680 --> 00:00:45,620 humans farther into space than we've 17 00:00:49,270 --> 00:00:47,690 ever been before and what you see in the 18 00:00:51,430 --> 00:00:49,280 background we actually use for testing 19 00:00:53,229 --> 00:00:51,440 here at Johnson Space Center but in 20 00:00:55,150 --> 00:00:53,239 Kennedy Space Center in Florida they're 21 00:00:58,209 --> 00:00:55,160 building the Orion is actually gonna be 22 00:01:00,220 --> 00:00:58,219 launched into space December when it is 23 00:01:01,930 --> 00:01:00,230 launched it's gonna travel 3,600 miles 24 00:01:03,819 --> 00:01:01,940 into space which is the farthest that 25 00:01:06,400 --> 00:01:03,829 any spacecraft built for humans has been 26 00:01:09,010 --> 00:01:06,410 in more than 40 years and then returned 27 00:01:11,020 --> 00:01:09,020 to Earth and 20,000 miles per hour and 28 00:01:12,640 --> 00:01:11,030 during temperatures at 4,000 degrees 29 00:01:13,540 --> 00:01:12,650 Fahrenheit as it travels to the Earth's 30 00:01:15,880 --> 00:01:13,550 atmosphere 31 00:01:18,760 --> 00:01:15,890 it's going to help us be sure that all 32 00:01:21,400 --> 00:01:18,770 the critical systems in - space and 33 00:01:23,680 --> 00:01:21,410 eventually Mars on future missions are 34 00:01:25,570 --> 00:01:23,690 up to the challenge but sometime between 35 00:01:27,160 --> 00:01:25,580 hitting Earth's atmosphere at 20,000 36 00:01:29,260 --> 00:01:27,170 miles per hour and launching them in the 37 00:01:33,210 --> 00:01:29,270 Pacific Ocean we need to slow the 38 00:01:37,720 --> 00:01:33,220 vehicle down to about 20 miles per hour 39 00:01:46,780 --> 00:01:37,730 that we're standing by in Yuma Arizona 40 00:01:49,150 --> 00:01:46,790 on the US Army landing recovery systems 41 00:01:50,980 --> 00:01:49,160 functional manager and then here with me 42 00:01:53,920 --> 00:01:50,990 at Johnson Space Center we also have 43 00:01:56,530 --> 00:01:53,930 Molly white and Orion aerothermodynamics 44 00:01:58,350 --> 00:01:56,540 engineers tell us some more about other 45 00:02:01,420 --> 00:01:58,360 tests that Orion's been going through 46 00:02:03,370 --> 00:02:01,430 and I did what in here are gonna be 47 00:02:05,470 --> 00:02:03,380 getting back from that test flight in 48 00:02:07,270 --> 00:02:05,480 December so we're gonna start here with 49 00:02:09,450 --> 00:02:07,280 Stu but remember they'll be taking 50 00:02:12,390 --> 00:02:09,460 questions with the 51 00:02:14,220 --> 00:02:12,400 test hashtag and just a few minutes that 52 00:02:17,090 --> 00:02:14,230 first let's go to su and see how things 53 00:02:19,950 --> 00:02:17,100 are looking they're in Yuma do hey 54 00:02:23,390 --> 00:02:19,960 Lauren Brandi how do you hear me just do 55 00:02:27,270 --> 00:02:24,600 all right 56 00:02:29,720 --> 00:02:27,280 good hey thanks for joining us you can 57 00:02:31,950 --> 00:02:29,730 see we're getting ready for the test 58 00:02:34,260 --> 00:02:31,960 like you mentioned we had a short delay 59 00:02:37,290 --> 00:02:34,270 one of the chasey aircraft that we used 60 00:02:39,930 --> 00:02:37,300 photograph the parachute deployment 61 00:02:42,420 --> 00:02:39,940 events had an issue and so we had to 62 00:02:45,230 --> 00:02:42,430 sort a up another aircraft and that 63 00:02:47,820 --> 00:02:45,240 caused us that slight delay but they're 64 00:02:51,330 --> 00:02:47,830 making their approach runs now and so 65 00:02:53,100 --> 00:02:51,340 we're in close to a good test like you 66 00:02:55,860 --> 00:02:53,110 mentioned this is one of our most 67 00:02:58,140 --> 00:02:55,870 challenging test this is a number 14 and 68 00:03:02,280 --> 00:02:58,150 harder series of 17 development tests 69 00:03:04,860 --> 00:03:02,290 this one were primarily test objective 70 00:03:07,500 --> 00:03:04,870 is to look at how the jettison Florida 71 00:03:09,450 --> 00:03:07,510 Bay cover works we've done that once 72 00:03:13,260 --> 00:03:09,460 we've done it a few times on the ground 73 00:03:14,910 --> 00:03:13,270 up at the Lockheed Denver facility this 74 00:03:16,530 --> 00:03:14,920 one were we've set up the test 75 00:03:18,590 --> 00:03:16,540 conditions to let the vehicle fall 76 00:03:21,480 --> 00:03:18,600 faster get a higher dynamic pressure 77 00:03:22,980 --> 00:03:21,490 give us a more challenging test 78 00:03:25,350 --> 00:03:22,990 objective and there's a little observe 79 00:03:28,530 --> 00:03:25,360 how the cover comes off and then we'll 80 00:03:31,170 --> 00:03:28,540 also look at one other planned failure 81 00:03:32,430 --> 00:03:31,180 will us skip what we call a reefing 82 00:03:35,130 --> 00:03:32,440 stage on one of the three main 83 00:03:38,010 --> 00:03:35,140 parachutes that will help us to get 84 00:03:39,300 --> 00:03:38,020 better correlation of our predictions 85 00:03:43,650 --> 00:03:39,310 and our models for the parachute 86 00:03:45,240 --> 00:03:43,660 performance let me pause I'll let you 87 00:03:49,710 --> 00:03:45,250 ask me questions instead of me just 88 00:03:50,670 --> 00:03:49,720 talking well before we go to Molly why 89 00:03:53,880 --> 00:03:50,680 don't you tell us a little bit about 90 00:03:57,630 --> 00:03:53,890 where you're standing all right yeah I'm 91 00:03:59,880 --> 00:03:57,640 out in the southwestern part of Arizona 92 00:04:01,440 --> 00:03:59,890 and I don't think it's quite book and a 93 00:04:03,360 --> 00:04:01,450 hundred degrees yet this morning it will 94 00:04:07,170 --> 00:04:03,370 eventually be reviewing the proving 95 00:04:09,840 --> 00:04:07,180 ground we use we work with the with the 96 00:04:11,670 --> 00:04:09,850 Army and the you know I humor proving 97 00:04:14,340 --> 00:04:11,680 ground is our test facility as you know 98 00:04:15,750 --> 00:04:14,350 the being a large it helps to have a 99 00:04:18,120 --> 00:04:15,760 large footprint when you're doing the 100 00:04:21,060 --> 00:04:18,130 parachute test like this and so Yuma has 101 00:04:23,880 --> 00:04:21,070 a large multi-purpose test range 102 00:04:27,450 --> 00:04:23,890 and we partnered up with them and we're 103 00:04:29,760 --> 00:04:27,460 out here north of Yuma south of 104 00:04:33,510 --> 00:04:29,770 quartzite if anybody's out there looking 105 00:04:35,970 --> 00:04:33,520 on google map so we're out there and the 106 00:04:38,760 --> 00:04:35,980 test range is about a mile or two wide 107 00:04:41,760 --> 00:04:38,770 and at five or ten miles long so that 108 00:04:44,760 --> 00:04:41,770 gives us the large footprint outside of 109 00:04:47,460 --> 00:04:44,770 a populated area where we can safely run 110 00:04:50,490 --> 00:04:47,470 these tests we've been working with Yuma 111 00:04:52,290 --> 00:04:50,500 for quite some time now they are great 112 00:04:58,170 --> 00:04:52,300 hosts for us and we have pretty good 113 00:05:06,360 --> 00:04:58,180 partnership and everything is looking 114 00:05:07,230 --> 00:05:06,370 okay and aircraft aircraft issues 115 00:05:09,510 --> 00:05:07,240 cleared up 116 00:05:11,580 --> 00:05:09,520 it is a we're right at the border of our 117 00:05:14,280 --> 00:05:11,590 ground winds otherwise the weather is 118 00:05:15,900 --> 00:05:14,290 looking fine it's a clear and sunny it's 119 00:05:20,430 --> 00:05:15,910 a beautiful day out here just getting a 120 00:05:22,470 --> 00:05:20,440 little hot dry after after landing one 121 00:05:25,020 --> 00:05:22,480 of our landing or one of our test 122 00:05:27,720 --> 00:05:25,030 constraints is to have ground winds that 123 00:05:29,700 --> 00:05:27,730 are low enough to allow the the teams to 124 00:05:31,830 --> 00:05:29,710 safely recover the parachutes the 125 00:05:34,830 --> 00:05:31,840 parachutes are effective enough that 126 00:05:36,660 --> 00:05:34,840 they will want to they can will and will 127 00:05:39,600 --> 00:05:36,670 re-inflate on the ground and it makes it 128 00:05:41,520 --> 00:05:39,610 the hazardous for the recovery crews so 129 00:05:43,950 --> 00:05:41,530 we're we're just at our limit we're able 130 00:05:46,200 --> 00:05:43,960 to work underneath that so that'll be no 131 00:05:50,220 --> 00:05:46,210 be good each of these main parachutes is 132 00:05:52,170 --> 00:05:50,230 116 feet diameter and so they if you can 133 00:05:54,210 --> 00:05:52,180 one of these inflated it captures a lot 134 00:05:58,890 --> 00:05:54,220 of wind and puts a pretty good load on 135 00:06:01,470 --> 00:05:58,900 the on the cargo and you not not have 136 00:06:03,300 --> 00:06:01,480 them whipping around when you're trying 137 00:06:05,150 --> 00:06:03,310 to recover them we take these chutes all 138 00:06:08,370 --> 00:06:05,160 of our test hardware we were cover it 139 00:06:12,900 --> 00:06:08,380 take it back to the hangar investigate 140 00:06:18,390 --> 00:06:12,910 it look for the not so obvious anomalies 141 00:06:21,149 --> 00:06:18,400 that we might buy all those small things 142 00:06:21,149 --> 00:06:21,159 we find 143 00:06:28,109 --> 00:06:24,959 we modify our shoot design and improve 144 00:06:29,669 --> 00:06:28,119 it just make it that much safer for the 145 00:06:38,639 --> 00:06:29,679 astronauts it will use these sinking 146 00:06:40,559 --> 00:06:38,649 future missions you've been out to quite 147 00:06:48,449 --> 00:06:40,569 a few of these tests probably and your 148 00:06:50,070 --> 00:06:48,459 job I did what repeat that for me we had 149 00:06:52,199 --> 00:06:50,080 a small aircraft go over and I didn't 150 00:06:55,559 --> 00:06:52,209 hear you totally clear serious I didn't 151 00:06:57,119 --> 00:06:55,569 hear then I know that you've seen a 152 00:07:04,049 --> 00:06:57,129 number of these tests kind of describe 153 00:07:06,600 --> 00:07:04,059 what will be yeah so the short version 154 00:07:08,999 --> 00:07:06,610 of the test sequence and as you 155 00:07:12,239 --> 00:07:09,009 mentioned and we start slowing we use 156 00:07:16,409 --> 00:07:12,249 the parachute to slow us down to about 157 00:07:17,549 --> 00:07:16,419 20 miles an hour this desk will start at 158 00:07:19,829 --> 00:07:17,559 35,000 feet 159 00:07:23,999 --> 00:07:19,839 so the same altitude that a commercial 160 00:07:27,569 --> 00:07:24,009 airliners flying at will extract the 161 00:07:29,279 --> 00:07:27,579 vehicle from the the c-17 and will let 162 00:07:32,339 --> 00:07:29,289 it start to fall we have what we call 163 00:07:36,029 --> 00:07:32,349 programmer chutes that allow it to fall 164 00:07:37,739 --> 00:07:36,039 at a predetermined speed we'll cut them 165 00:07:39,480 --> 00:07:37,749 away and then we basically at that point 166 00:07:41,069 --> 00:07:39,490 get on testing 167 00:07:43,739 --> 00:07:41,079 well let the vehicle drop a little bit 168 00:07:45,540 --> 00:07:43,749 more to gain some more speed the forward 169 00:07:49,079 --> 00:07:45,550 Bay cover will be three forward Bay 170 00:07:50,639 --> 00:07:49,089 cover shoots will deploy for just for a 171 00:07:52,649 --> 00:07:50,649 second and a half and then we'll fire 172 00:07:54,749 --> 00:07:52,659 the thrusters jettison to the forward 173 00:07:57,269 --> 00:07:54,759 Bay cover as soon as it's out of the way 174 00:07:59,909 --> 00:07:57,279 the the drogue parachutes start to 175 00:08:01,169 --> 00:07:59,919 deploy we ride the vehicle or the 176 00:08:02,969 --> 00:08:01,179 vehicle rides down on those drogue 177 00:08:06,029 --> 00:08:02,979 chutes through its sequence the two 178 00:08:07,980 --> 00:08:06,039 drones cut away and then the three pilot 179 00:08:09,899 --> 00:08:07,990 chutes are mortar deployed from the 180 00:08:13,619 --> 00:08:09,909 vehicle and they pull the three big 181 00:08:15,029 --> 00:08:13,629 large main parachutes out and Rams got 182 00:08:18,689 --> 00:08:15,039 her we got our camera out here and he's 183 00:08:21,719 --> 00:08:18,699 going to do his best to track it down if 184 00:08:24,029 --> 00:08:21,729 if he manages to track the get a video 185 00:08:25,259 --> 00:08:24,039 shot of the payload coming out of the 186 00:08:29,159 --> 00:08:25,269 airplane it would be quite an amazing 187 00:08:29,609 --> 00:08:29,169 feat since he's you know got a 35,000 188 00:08:32,579 --> 00:08:29,619 foot 189 00:08:33,929 --> 00:08:32,589 altitude moving target to deal with but 190 00:08:34,750 --> 00:08:33,939 as soon as we get under main chutes 191 00:08:36,960 --> 00:08:34,760 he'll be able to 192 00:08:42,659 --> 00:08:36,970 video tape and you'll be able to watch 193 00:08:46,930 --> 00:08:42,669 watch the final phase of the deployment 194 00:08:49,180 --> 00:08:46,940 how long does it take from the time we 195 00:08:50,910 --> 00:08:49,190 come out of the airplane till we're on 196 00:08:53,260 --> 00:08:50,920 the ground and the shoots are deflated 197 00:08:55,630 --> 00:08:53,270 seven eight nine minutes something like 198 00:08:58,480 --> 00:08:55,640 that they vary from test to test because 199 00:09:01,050 --> 00:08:58,490 we modify our test objectives and so 200 00:09:04,180 --> 00:09:01,060 sometimes we let the vehicle for farther 201 00:09:06,610 --> 00:09:04,190 start and higher up if we fail a 202 00:09:08,650 --> 00:09:06,620 parachute will drop faster in this case 203 00:09:10,630 --> 00:09:08,660 we're under three parachutes and so our 204 00:09:16,840 --> 00:09:10,640 normal descent rate is 25 feet per 205 00:09:18,280 --> 00:09:16,850 second so last question for you for now 206 00:09:21,790 --> 00:09:18,290 why don't you tell us what your role is 207 00:09:24,490 --> 00:09:21,800 in all of this all right I'm as you said 208 00:09:27,700 --> 00:09:24,500 on the functional area manager so within 209 00:09:31,180 --> 00:09:27,710 the Orion program my your responsibility 210 00:09:33,310 --> 00:09:31,190 is all of the hardware that we build on 211 00:09:35,170 --> 00:09:33,320 the vehicle that is required for landing 212 00:09:38,440 --> 00:09:35,180 recovery so parachute systems the 213 00:09:40,690 --> 00:09:38,450 mortars the up writing bags that we use 214 00:09:42,490 --> 00:09:40,700 to make sure the vehicle gets into a 215 00:09:46,270 --> 00:09:42,500 proper position after we land in the 216 00:09:48,400 --> 00:09:46,280 ocean my role was its Technic it's a mix 217 00:09:54,340 --> 00:09:48,410 of technical as well as schedule and 218 00:09:56,340 --> 00:09:54,350 cost I'm try to balance our our desires 219 00:10:00,100 --> 00:09:56,350 to have the safest system we can have 220 00:10:02,080 --> 00:10:00,110 with the available funds we got and and 221 00:10:04,150 --> 00:10:02,090 within the schedule we have to support 222 00:10:06,550 --> 00:10:04,160 our mission so I'm always one of the 223 00:10:08,620 --> 00:10:06,560 ones one of the engineers that trade 224 00:10:12,660 --> 00:10:08,630 those different aspects of our design 225 00:10:15,640 --> 00:10:12,670 back and forth and work with the team 226 00:10:19,890 --> 00:10:15,650 make it as safe as we can within our 227 00:10:28,930 --> 00:10:19,900 within limits that we work under all 228 00:10:30,130 --> 00:10:28,940 right well thanks so much with me only 229 00:10:32,640 --> 00:10:30,140 why don't you tell us a little bit about 230 00:10:35,470 --> 00:10:32,650 what you do 231 00:10:37,660 --> 00:10:35,480 thanks brandy well you've been talking a 232 00:10:40,030 --> 00:10:37,670 lot about the parachute test which tests 233 00:10:42,640 --> 00:10:40,040 orion from tens of thousands of feet on 234 00:10:45,400 --> 00:10:42,650 down to the surface of the earth we also 235 00:10:48,760 --> 00:10:45,410 need to know how a ryan behaves from 236 00:10:51,040 --> 00:10:48,770 entry interface or 400,000 feet 237 00:10:53,170 --> 00:10:51,050 on down to when one sits on the shoots 238 00:10:55,780 --> 00:10:53,180 an Orion's first flight test this 239 00:10:57,490 --> 00:10:55,790 upcoming fall is going to tell us how a 240 00:10:59,920 --> 00:10:57,500 Ryan behaves in the actual flight 241 00:11:02,260 --> 00:10:59,930 environment once before it gets down 242 00:11:04,660 --> 00:11:02,270 onto those parachutes I work here at the 243 00:11:07,180 --> 00:11:04,670 Johnson Space Center for Orion Aero 244 00:11:09,220 --> 00:11:07,190 sciences and we predict the aerodynamic 245 00:11:11,800 --> 00:11:09,230 and aerothermodynamic environments 246 00:11:14,889 --> 00:11:11,810 around the Orion crew vehicle and the 247 00:11:17,110 --> 00:11:14,899 launch abort system for design we use a 248 00:11:19,510 --> 00:11:17,120 combination of computer simulations and 249 00:11:21,519 --> 00:11:19,520 Windtunnel testing to create those 250 00:11:23,710 --> 00:11:21,529 environments for design but we actually 251 00:11:26,199 --> 00:11:23,720 don't know how well we did until we get 252 00:11:27,880 --> 00:11:26,209 that flight test data back and once we 253 00:11:29,380 --> 00:11:27,890 get that flight test data back we 254 00:11:31,150 --> 00:11:29,390 compare it to what our computer 255 00:11:33,370 --> 00:11:31,160 predictions and our wind tunnel test 256 00:11:40,210 --> 00:11:33,380 data told us to see how well the two 257 00:11:41,860 --> 00:11:40,220 matched up so what exactly are you 258 00:11:44,350 --> 00:11:41,870 looking for in the wind tunnel test what 259 00:11:48,400 --> 00:11:44,360 what does that tell you that you need to 260 00:11:50,170 --> 00:11:48,410 know before we go fly yeah for wind 261 00:11:52,269 --> 00:11:50,180 tunnel testing we take scaled-down 262 00:11:54,819 --> 00:11:52,279 models of either the launch abort system 263 00:11:57,310 --> 00:11:54,829 or the Orion crew module you know 264 00:12:00,010 --> 00:11:57,320 anywhere from a couple of inches on to a 265 00:12:02,470 --> 00:12:00,020 couple of feet which is obviously not 266 00:12:04,240 --> 00:12:02,480 the real size of the vehicle and so we 267 00:12:06,790 --> 00:12:04,250 take temperature measurements pressure 268 00:12:09,610 --> 00:12:06,800 measurements we look at you know loading 269 00:12:12,100 --> 00:12:09,620 lift and drag and then we also look at 270 00:12:14,380 --> 00:12:12,110 heat transfer to the surface and we take 271 00:12:16,240 --> 00:12:14,390 those measurements and try and scale 272 00:12:18,730 --> 00:12:16,250 them we use various parameters and 273 00:12:21,130 --> 00:12:18,740 assumptions to scale them to flight we 274 00:12:23,170 --> 00:12:21,140 also use our computers to predict what 275 00:12:24,880 --> 00:12:23,180 we saw in the wind tunnels and we 276 00:12:26,769 --> 00:12:24,890 extrapolate that as well to fly it we 277 00:12:28,660 --> 00:12:26,779 say okay we did really well at 278 00:12:30,670 --> 00:12:28,670 predicting the wind tunnel test data so 279 00:12:32,470 --> 00:12:30,680 we'll probably do well at predicting the 280 00:12:34,210 --> 00:12:32,480 flight test data we don't know that 281 00:12:40,170 --> 00:12:34,220 exactly until we get the flight test 282 00:12:44,440 --> 00:12:40,180 data and all that's necessary before the 283 00:12:48,670 --> 00:12:44,450 before the actual launch in December 284 00:12:51,250 --> 00:12:48,680 right and one of the things that we're 285 00:12:53,170 --> 00:12:51,260 working on right now coming for the 286 00:12:56,380 --> 00:12:53,180 flight in December is we're getting all 287 00:12:58,660 --> 00:12:56,390 of our processing strips and everything 288 00:13:00,490 --> 00:12:58,670 and tools together to prepare for that 289 00:13:02,620 --> 00:13:00,500 flight test data because it's going to 290 00:13:04,930 --> 00:13:02,630 be a pretty short turnaround between 291 00:13:06,699 --> 00:13:04,940 when we get that flight test data and 292 00:13:08,970 --> 00:13:06,709 when we're going to need to apply it for 293 00:13:14,110 --> 00:13:08,980 our design for Orion second flight test 294 00:13:15,939 --> 00:13:14,120 after that okay well tell us a little 295 00:13:20,220 --> 00:13:15,949 bit about your background how did you 296 00:13:22,269 --> 00:13:20,230 how did you come into this job well I 297 00:13:24,430 --> 00:13:22,279 did my undergrad in aerospace 298 00:13:27,550 --> 00:13:24,440 engineering at Iowa State University and 299 00:13:29,710 --> 00:13:27,560 while I was an undergrad I got a co-op 300 00:13:31,689 --> 00:13:29,720 or kind of intern opportunity here at 301 00:13:33,550 --> 00:13:31,699 the Johnson Space Center and I worked 302 00:13:35,379 --> 00:13:33,560 with the branch that I currently work 303 00:13:36,999 --> 00:13:35,389 with here at Johnson Space Center and I 304 00:13:38,920 --> 00:13:37,009 love the work that they do it was very 305 00:13:41,530 --> 00:13:38,930 exciting they were working on designing 306 00:13:44,259 --> 00:13:41,540 a real spacecraft to go farther than 307 00:13:46,449 --> 00:13:44,269 we've ever gone before in space and 308 00:13:48,309 --> 00:13:46,459 carry astronauts there and do missions 309 00:13:49,840 --> 00:13:48,319 and eventually go on to Mars and so I 310 00:13:52,240 --> 00:13:49,850 was really just enthralled and caught up 311 00:13:54,550 --> 00:13:52,250 in that and they offered me a job when I 312 00:13:55,990 --> 00:13:54,560 graduated and I was ecstatic to accept 313 00:14:00,730 --> 00:13:56,000 it and come work here at the Johnson 314 00:14:04,139 --> 00:14:00,740 Space Center what's been the the funnest 315 00:14:09,069 --> 00:14:07,420 probably one of the most exciting or fun 316 00:14:10,840 --> 00:14:09,079 things other than this upcoming flight 317 00:14:12,189 --> 00:14:10,850 test which I can't even imagine what its 318 00:14:14,650 --> 00:14:12,199 gonna feel like once we get that data 319 00:14:17,139 --> 00:14:14,660 back was a wind tunnel test that we did 320 00:14:18,670 --> 00:14:17,149 where we took a scaled-down size of the 321 00:14:21,699 --> 00:14:18,680 Orion crew module like what you see 322 00:14:24,370 --> 00:14:21,709 behind me only it was about 12 inches in 323 00:14:26,740 --> 00:14:24,380 diameter so a lot smaller and we took 324 00:14:28,860 --> 00:14:26,750 measurements where we created the 325 00:14:31,929 --> 00:14:28,870 reaction control system which fires 326 00:14:33,340 --> 00:14:31,939 plumes and gases outside of the vehicle 327 00:14:35,410 --> 00:14:33,350 to orient it during reentry 328 00:14:37,150 --> 00:14:35,420 we fired those in the wind tunnel test 329 00:14:39,129 --> 00:14:37,160 and took measurements and that was a 330 00:14:40,960 --> 00:14:39,139 really complicated really extensive test 331 00:14:42,910 --> 00:14:40,970 and getting those measurements back 332 00:14:45,460 --> 00:14:42,920 looking at that data and trying to apply 333 00:14:47,470 --> 00:14:45,470 it for the real vehicle was exciting it 334 00:14:51,280 --> 00:14:47,480 was a probably about a year your two 335 00:14:52,960 --> 00:14:51,290 year-long project that does sound cool 336 00:14:54,579 --> 00:14:52,970 but I guess probably you're really 337 00:14:59,710 --> 00:14:54,589 looking forward to the to the launch in 338 00:15:02,050 --> 00:14:59,720 December definitely I get kind of giddy 339 00:15:03,939 --> 00:15:02,060 a little bit thinking about it and it's 340 00:15:07,509 --> 00:15:03,949 gonna be something like we've never seen 341 00:15:09,129 --> 00:15:07,519 before all right well I think we've 342 00:15:11,230 --> 00:15:09,139 gotten still about 15 minutes left 343 00:15:12,699 --> 00:15:11,240 before we get to see the drop test but 344 00:15:14,199 --> 00:15:12,709 in the meantime we're gonna be taking 345 00:15:16,509 --> 00:15:14,209 some questions from social media don't 346 00:15:16,840 --> 00:15:16,519 forget you can send them in here on 347 00:15:19,710 --> 00:15:16,850 Google 348 00:15:22,509 --> 00:15:19,720 Plus or to twitter using the hashtag 349 00:15:24,400 --> 00:15:22,519 orion test so send in your questions and 350 00:15:26,170 --> 00:15:24,410 we'll we'll see if how many we can get 351 00:15:28,629 --> 00:15:26,180 answered before the drop test actually 352 00:15:34,780 --> 00:15:28,639 starts and i think we'll start with one 353 00:15:37,689 --> 00:15:34,790 from twitter it's why why does NASA's 354 00:15:40,059 --> 00:15:37,699 spacecraft not use the dragon 355 00:15:41,680 --> 00:15:40,069 landing technique of using rocket 356 00:15:42,910 --> 00:15:41,690 boosters to slow down the spacecraft so 357 00:15:45,600 --> 00:15:42,920 I'm guessing that's probably a good one 358 00:15:48,460 --> 00:15:45,610 first do do did you uh probably that 359 00:15:53,499 --> 00:15:48,470 yeah repeat it one more time for me real 360 00:15:56,290 --> 00:15:53,509 quick make sure I got it all why doesn't 361 00:15:58,930 --> 00:15:56,300 Ryan use that thrusters to slow down and 362 00:16:00,910 --> 00:15:58,940 land instead of parachutes okay yeah 363 00:16:04,300 --> 00:16:00,920 thank you actually we looked at that so 364 00:16:07,360 --> 00:16:04,310 I've worked on Orion since 2006 and 7 365 00:16:11,319 --> 00:16:07,370 and early in the program we looked at 366 00:16:12,519 --> 00:16:11,329 that when we had when we were early in 367 00:16:14,860 --> 00:16:12,529 the program we thought about land 368 00:16:18,249 --> 00:16:14,870 landing and we traded land landing 369 00:16:19,449 --> 00:16:18,259 versus water landing and for the types 370 00:16:21,759 --> 00:16:19,459 of missions that we're doing for deep 371 00:16:23,170 --> 00:16:21,769 space missions where mass is at a 372 00:16:25,870 --> 00:16:23,180 premium and we try to make the vehicle 373 00:16:29,170 --> 00:16:25,880 as light as we can it turned out that a 374 00:16:32,379 --> 00:16:29,180 land landing was going to be about 1,500 375 00:16:35,259 --> 00:16:32,389 pounds heavier for the vehicle and so we 376 00:16:37,720 --> 00:16:35,269 chose to go away from a land landing 377 00:16:40,030 --> 00:16:37,730 capability as a nominal capability to 378 00:16:42,309 --> 00:16:40,040 save that mass when we were looking at 379 00:16:45,759 --> 00:16:42,319 it thrusters were an option just like 380 00:16:49,269 --> 00:16:45,769 dragon uses just like the Soyuz uses we 381 00:16:51,460 --> 00:16:49,279 evaluated that we evaluated airbags and 382 00:16:53,559 --> 00:16:51,470 some of some other concepts as well but 383 00:16:56,740 --> 00:16:53,569 at the end of the day the trade was more 384 00:17:02,410 --> 00:16:56,750 of a decision to save save the up mass 385 00:17:03,939 --> 00:17:02,420 and apply it to science and cargo why 386 00:17:14,439 --> 00:17:03,949 don't you explain why the mass is so 387 00:17:15,069 --> 00:17:14,449 important to us hardware the low-earth 388 00:17:18,850 --> 00:17:15,079 orbit 389 00:17:20,799 --> 00:17:18,860 cargo end or astronauts depending on the 390 00:17:22,840 --> 00:17:20,809 the vehicle you're sitting on you have 391 00:17:25,210 --> 00:17:22,850 some I'll say some other flexibilities 392 00:17:28,810 --> 00:17:25,220 in your design and your trade space to 393 00:17:31,470 --> 00:17:28,820 to choose how much structure you put in 394 00:17:34,470 --> 00:17:31,480 how much we use it 395 00:17:38,880 --> 00:17:34,480 and when you're looking at a deep-space 396 00:17:41,549 --> 00:17:38,890 mission as we our mass is more of a 397 00:17:43,890 --> 00:17:41,559 premium you want to maximize the amount 398 00:17:46,020 --> 00:17:43,900 of cargo astronauts and science that you 399 00:17:47,370 --> 00:17:46,030 can take to whatever that destination is 400 00:17:50,880 --> 00:17:47,380 right you've still got to lift it off 401 00:17:52,590 --> 00:17:50,890 the surface of it of the earth and so it 402 00:17:55,650 --> 00:17:52,600 ends up being a function of you know 403 00:17:58,040 --> 00:17:55,660 what what's your primary goal back and 404 00:18:00,930 --> 00:17:58,050 forth the lower Earth orbit which is a 405 00:18:03,480 --> 00:18:00,940 challenging mission in itself but a deep 406 00:18:06,299 --> 00:18:03,490 space mission puts a different different 407 00:18:08,220 --> 00:18:06,309 priority on taking mass out of your 408 00:18:10,350 --> 00:18:08,230 vehicle so you can maximize what you 409 00:18:14,880 --> 00:18:10,360 have to what you can carry with you for 410 00:18:17,370 --> 00:18:14,890 your longer duration missions that makes 411 00:18:21,780 --> 00:18:17,380 it so we've got a question from Anthony 412 00:18:23,730 --> 00:18:21,790 age entry and who asked in fact even 413 00:18:26,370 --> 00:18:23,740 though I Ryan is designed to land on the 414 00:18:34,440 --> 00:18:26,380 ocean if it could land on land if it had 415 00:18:37,320 --> 00:18:34,450 to yes you know the the you'll see in 416 00:18:42,990 --> 00:18:37,330 about 15 minutes we clearly can and you 417 00:18:45,870 --> 00:18:43,000 certainly can the landing loads are are 418 00:18:47,640 --> 00:18:45,880 different but landing on land versus 419 00:18:49,710 --> 00:18:47,650 landing on water from a structural 420 00:18:53,990 --> 00:18:49,720 perspective isn't is it massively 421 00:18:57,570 --> 00:18:54,000 different we still have you designed for 422 00:19:00,090 --> 00:18:57,580 hitting soil or you have to design for 423 00:19:03,840 --> 00:19:00,100 hitting into a wave and so in either 424 00:19:08,010 --> 00:19:03,850 case and we we take that into our design 425 00:19:11,540 --> 00:19:08,020 trades and protect for that will target 426 00:19:14,700 --> 00:19:11,550 the land off the California coast and so 427 00:19:16,890 --> 00:19:14,710 in general it would take a take a fair 428 00:19:20,640 --> 00:19:16,900 number of failures for us to go long on 429 00:19:22,140 --> 00:19:20,650 our entry and land have a land landing 430 00:19:23,910 --> 00:19:22,150 so it you know will land off the coast 431 00:19:26,100 --> 00:19:23,920 of the west coast and if something were 432 00:19:28,500 --> 00:19:26,110 to come up and we had what we call a 433 00:19:30,180 --> 00:19:28,510 ballistic entry we would end up coming 434 00:19:33,390 --> 00:19:30,190 up short and landing further out in the 435 00:19:35,160 --> 00:19:33,400 ocean but the capability exists how's 436 00:19:39,120 --> 00:19:35,170 that my parachutes don't care whether we 437 00:19:39,560 --> 00:19:39,130 land on land or land on water I'm 438 00:19:41,090 --> 00:19:39,570 getting 439 00:19:42,770 --> 00:19:41,100 a little easier for us to target an 440 00:19:46,310 --> 00:19:42,780 ocean landing since it's such a big 441 00:19:48,650 --> 00:19:46,320 ocean and and noble living in it that's 442 00:19:51,770 --> 00:19:48,660 true and I went back to that first 443 00:19:53,570 --> 00:19:51,780 question one of the one of the reasons 444 00:19:55,610 --> 00:19:53,580 that land landing is a is amassed 445 00:20:01,160 --> 00:19:55,620 penalty is again when you're coming back 446 00:20:03,380 --> 00:20:01,170 from the deep space location if you have 447 00:20:07,970 --> 00:20:03,390 an issue you still have to protect for 448 00:20:10,550 --> 00:20:07,980 the ability of landing on and so you've 449 00:20:20,990 --> 00:20:10,560 got to carry both systems and so that 450 00:20:23,240 --> 00:20:21,000 was another reason we shifted to some 451 00:20:26,480 --> 00:20:23,250 detail I think you've been we can quiz 452 00:20:28,370 --> 00:20:26,490 you on this - he wants says he's got I 453 00:20:30,500 --> 00:20:28,380 think that entering the atmosphere slows 454 00:20:32,390 --> 00:20:30,510 our Ryan down a lot but how much what 455 00:20:37,100 --> 00:20:32,400 what's people the vehicle be going out 456 00:20:52,280 --> 00:20:37,110 when the let's see we we start our 457 00:20:54,020 --> 00:20:52,290 sequence parachute sequence starts and 458 00:20:56,780 --> 00:20:54,030 so we as you mentioned we enter it 459 00:21:00,350 --> 00:20:56,790 around 3 ft 1 will enter at 20,000 miles 460 00:21:02,900 --> 00:21:00,360 an hour and and come through the 461 00:21:04,130 --> 00:21:02,910 atmosphere and that friction of sliding 462 00:21:07,130 --> 00:21:04,140 down through the atmosphere will have 463 00:21:09,500 --> 00:21:07,140 slowed us down at that point that's 464 00:21:12,170 --> 00:21:09,510 assuming you know myoh he's got to get 465 00:21:13,760 --> 00:21:12,180 all of her predictions right for me but 466 00:21:15,350 --> 00:21:13,770 as soon as mildly bitter did her work 467 00:21:17,240 --> 00:21:15,360 and she's pretty smart so I'm assuming 468 00:21:22,790 --> 00:21:17,250 she's got her her numbers right we're in 469 00:21:25,160 --> 00:21:22,800 the range of 350 when we deploy okay and 470 00:21:27,950 --> 00:21:25,170 kind of a related question and we have a 471 00:21:30,490 --> 00:21:27,960 handle on Twitter and asking on behalf 472 00:21:33,470 --> 00:21:30,500 of his 11 year old son who's watching 473 00:21:37,850 --> 00:21:33,480 how heavy will Orion be when the 474 00:21:43,430 --> 00:21:37,860 parachutes deploy we have a landed mass 475 00:21:45,680 --> 00:21:43,440 in it it varies a little bit but that's 476 00:21:48,530 --> 00:21:45,690 a good round number keeping your head 477 00:21:52,950 --> 00:21:48,540 and it's the 20,000 pounds is generally 478 00:21:58,450 --> 00:21:56,440 okay great let's see we've got still 479 00:22:00,010 --> 00:21:58,460 about nine minutes I think before the 480 00:22:02,380 --> 00:22:00,020 test and we'll keep going keep sending 481 00:22:06,430 --> 00:22:02,390 your questions in with a hashtag Orion 482 00:22:08,860 --> 00:22:06,440 tests our next one from in ever eaten 483 00:22:11,889 --> 00:22:08,870 this question is is the forward Bay 484 00:22:14,409 --> 00:22:11,899 cover recoverable or reusable and it 485 00:22:17,110 --> 00:22:14,419 might be a good question to jump off of 486 00:22:20,919 --> 00:22:17,120 and talk about what all we might be able 487 00:22:24,240 --> 00:22:20,929 to reuse online so the format cover is 488 00:22:32,820 --> 00:22:24,250 recoverable when we land in the ocean 489 00:22:35,380 --> 00:22:32,830 the expectation maintain enough buoyancy 490 00:22:39,250 --> 00:22:35,390 will clearly recover here after the test 491 00:22:41,649 --> 00:22:39,260 today it's not intended to be reusable 492 00:22:44,740 --> 00:22:41,659 the parachutes that take it off are 493 00:22:47,350 --> 00:22:44,750 sized to be just big enough to get it 494 00:22:49,810 --> 00:22:47,360 off and do that job they're not sized to 495 00:22:52,269 --> 00:22:49,820 give it a soft landing so the cover hits 496 00:22:54,460 --> 00:22:52,279 it around 50 miles an hour and so we 497 00:22:59,860 --> 00:22:54,470 would expect it to get some damage when 498 00:23:02,409 --> 00:22:59,870 it lands and then just globally we will 499 00:23:06,220 --> 00:23:02,419 reuse a lot of our computers and other 500 00:23:08,370 --> 00:23:06,230 avionics again early in the program we 501 00:23:11,169 --> 00:23:08,380 considered reusing the structure and 502 00:23:12,669 --> 00:23:11,179 again since this is a human vehicle if 503 00:23:15,399 --> 00:23:12,679 you're going to reuse your structure you 504 00:23:17,350 --> 00:23:15,409 need to inspect it make sure that after 505 00:23:19,060 --> 00:23:17,360 a landing that all of your welds and 506 00:23:22,710 --> 00:23:19,070 other structural components are still 507 00:23:25,870 --> 00:23:22,720 intact and the the effort to inspect it 508 00:23:29,080 --> 00:23:25,880 is is a lot of work and is almost as 509 00:23:31,919 --> 00:23:29,090 much work as knocking out a new piece of 510 00:23:34,060 --> 00:23:31,929 structure and building up around 511 00:23:36,100 --> 00:23:34,070 primarily it's our avionics which are 512 00:23:40,029 --> 00:23:36,110 some of the high dollar value items that 513 00:23:41,169 --> 00:23:40,039 are being reused okay there was a second 514 00:23:44,320 --> 00:23:41,179 part to Ben's question he said if we 515 00:23:48,460 --> 00:23:44,330 weren't going to reuse it why why give 516 00:23:50,260 --> 00:23:48,470 it parachute the the parachutes and 517 00:23:53,159 --> 00:23:50,270 there are there are three parachutes and 518 00:23:55,539 --> 00:23:53,169 three thrusters and they they work in 519 00:23:59,710 --> 00:23:55,549 partnership to make sure you can get the 520 00:24:01,139 --> 00:23:59,720 cover off the cover the job of the cover 521 00:24:02,820 --> 00:24:01,149 all through the mission 522 00:24:06,269 --> 00:24:02,830 to protect the forebay which includes 523 00:24:09,749 --> 00:24:06,279 the rest of the parachutes from thermal 524 00:24:10,769 --> 00:24:09,759 environment mmod other just all the 525 00:24:13,499 --> 00:24:10,779 other environments that we have to 526 00:24:15,060 --> 00:24:13,509 protect for and so it's got to get off 527 00:24:17,820 --> 00:24:15,070 and get out of the way for the rest of 528 00:24:19,919 --> 00:24:17,830 the shoots to do a job I liken it to the 529 00:24:24,060 --> 00:24:19,929 first domino has to fall in the Train of 530 00:24:26,190 --> 00:24:24,070 dominoes and so it's from what from the 531 00:24:28,639 --> 00:24:26,200 data that I've seen parachutes alone 532 00:24:31,200 --> 00:24:28,649 could probably take the cover off 533 00:24:32,879 --> 00:24:31,210 thrusters alone could probably take it 534 00:24:34,469 --> 00:24:32,889 off but we put them together to make 535 00:24:38,719 --> 00:24:34,479 sure that it gets off and gets out of 536 00:24:42,709 --> 00:24:38,729 the way and stays and I just kind of 537 00:24:44,940 --> 00:24:42,719 think for two minutes and start the test 538 00:24:47,430 --> 00:24:44,950 few minutes I'm starting the test okay 539 00:24:50,969 --> 00:24:47,440 well while we're waiting on that another 540 00:24:53,869 --> 00:24:50,979 question that we had was what what 541 00:24:56,639 --> 00:24:53,879 happens if one of the parachute fails 542 00:25:00,509 --> 00:24:56,649 well we actually designed that in and 543 00:25:02,639 --> 00:25:00,519 certain tests we will plan those landed 544 00:25:06,180 --> 00:25:02,649 and we'll demonstrate that the the 545 00:25:08,759 --> 00:25:06,190 vehicle assumes of Engineers that design 546 00:25:10,919 --> 00:25:08,769 the structure assume that one of our 547 00:25:12,690 --> 00:25:10,929 main parachutes will feel to fail and so 548 00:25:14,879 --> 00:25:12,700 they build the structure strong enough 549 00:25:17,609 --> 00:25:14,889 to survive a landing under two 550 00:25:19,379 --> 00:25:17,619 parachutes all of our parachutes have 551 00:25:21,989 --> 00:25:19,389 redundancy built into them we call it 552 00:25:23,759 --> 00:25:21,999 fault tolerance and so if only one for 553 00:25:25,649 --> 00:25:23,769 Bay cover if before they cover chute 554 00:25:29,909 --> 00:25:25,659 doesn't work they'll still deploy if one 555 00:25:32,729 --> 00:25:29,919 of the two drugs fails to to deploy will 556 00:25:37,379 --> 00:25:32,739 still get on mains properly so that's 557 00:25:40,560 --> 00:25:37,389 part of our design activity we are very 558 00:25:42,829 --> 00:25:40,570 close to certain the tests okay we'll 559 00:25:46,680 --> 00:25:42,839 keep watching them just for the viewers 560 00:25:49,859 --> 00:25:46,690 you're with us that'd probably be a bit 561 00:25:51,539 --> 00:25:49,869 of a challenge for us to lock on to it 562 00:25:54,719 --> 00:25:51,549 but it looks like we see the crack there 563 00:25:57,060 --> 00:25:54,729 and that's what I Ryan or the test 564 00:25:58,709 --> 00:25:57,070 version of Orion is inside of right now 565 00:26:02,430 --> 00:25:58,719 and we'll be pushed out the back up for 566 00:26:04,139 --> 00:26:02,440 the test and I'll just give you a call 567 00:26:09,630 --> 00:26:04,149 as I can watch it if you if you'd like 568 00:26:19,950 --> 00:26:15,930 we're out of the airplane a good initial 569 00:26:24,750 --> 00:26:19,960 extraction the test vehicle the PTV is 570 00:26:41,879 --> 00:26:24,760 away from its lid I'm coming down under 571 00:26:49,599 --> 00:26:43,719 we're still falling out of the 572 00:26:50,829 --> 00:26:49,609 programmers just we've got the 573 00:26:54,989 --> 00:26:50,839 programmers away we're gonna let 574 00:27:00,070 --> 00:26:56,919 it's to tell us that given look that 575 00:27:02,019 --> 00:27:00,080 freefall this freefall allows gravity to 576 00:27:05,529 --> 00:27:02,029 do its job and allow us to accelerate to 577 00:27:08,409 --> 00:27:05,539 our test condition and the faster we let 578 00:27:09,969 --> 00:27:08,419 the vehicle fall you know the more it is 579 00:27:13,089 --> 00:27:09,979 able to accelerate and give us a more 580 00:27:15,669 --> 00:27:13,099 representative chest condition the 581 00:27:17,879 --> 00:27:15,679 closer is more closely matches the 582 00:27:35,829 --> 00:27:17,889 flight injury that we'll see during ft-1 583 00:27:38,589 --> 00:27:35,839 and we better under drugs so we've had a 584 00:27:40,719 --> 00:27:38,599 good for debate cover separation I'm 585 00:27:46,859 --> 00:27:40,729 just tracking the the PTV the test 586 00:28:02,079 --> 00:27:53,109 and we just cut away three pilots out 587 00:28:03,819 --> 00:28:02,089 the means that started inflating just 588 00:28:06,539 --> 00:28:03,829 heard the pop from the chute inflating 589 00:28:08,859 --> 00:28:06,549 one of I know a fred has this on camera 590 00:28:11,409 --> 00:28:08,869 one shoots inflated the other two are 591 00:28:13,529 --> 00:28:11,419 not yet this was one of our other 592 00:28:16,989 --> 00:28:13,539 players just objectives which was 593 00:28:19,569 --> 00:28:16,999 simulating well good yeah and so that's 594 00:28:22,239 --> 00:28:19,579 simulating what happens if one of the 595 00:28:25,619 --> 00:28:22,249 reefing stages opens prematurely for 596 00:28:28,209 --> 00:28:25,629 some reason and if it skips a stage 597 00:28:31,899 --> 00:28:28,219 because we designed this assuming that 598 00:28:34,479 --> 00:28:31,909 the parachutes here the reefing yeah 599 00:28:39,430 --> 00:28:34,489 thank you yeah reefing is is a way to 600 00:28:45,009 --> 00:28:39,440 open the the parachute in in gently or 601 00:28:47,649 --> 00:28:45,019 softly if you went full open its think 602 00:28:49,329 --> 00:28:47,659 of going extremely fast and hitting your 603 00:28:52,589 --> 00:28:49,339 brakes really really hard you put a lot 604 00:28:54,490 --> 00:28:52,599 of energy into things right it's it's a 605 00:28:56,230 --> 00:28:54,500 dumps a lot of energy 606 00:28:59,260 --> 00:28:56,240 into the structure of the vehicle and in 607 00:29:01,899 --> 00:28:59,270 the parachute and so we have ropes that 608 00:29:04,409 --> 00:29:01,909 constrain the diameter of the parachute 609 00:29:08,409 --> 00:29:04,419 and they have pyrotechnic timers that 610 00:29:11,020 --> 00:29:08,419 allow them to open up say 10% initially 611 00:29:12,970 --> 00:29:11,030 and then I think finally remembers the 612 00:29:14,470 --> 00:29:12,980 exact number I think it's 10 and then 20 613 00:29:15,850 --> 00:29:14,480 percent and then we go full open and 614 00:29:19,840 --> 00:29:15,860 that allows you to open up the chutes 615 00:29:22,120 --> 00:29:19,850 gracefully and kind of more slowly 616 00:29:24,220 --> 00:29:22,130 spread the energy into the parachutes 617 00:29:25,870 --> 00:29:24,230 and end of the vehicle again by reefing 618 00:29:29,520 --> 00:29:25,880 you kind of control and manage that 619 00:29:32,049 --> 00:29:29,530 energy and it allows you to not design 620 00:29:36,850 --> 00:29:32,059 and carry quite as much mass in the 621 00:29:38,730 --> 00:29:36,860 system well it looks great from here 622 00:29:42,010 --> 00:29:38,740 we're seeing really good do you think so 623 00:29:44,140 --> 00:29:42,020 we're getting that for us yes while we 624 00:29:46,299 --> 00:29:44,150 watch it make its way down to the ground 625 00:29:48,640 --> 00:29:46,309 we can take a few more questions we 626 00:29:51,039 --> 00:29:48,650 actually won four we're Molly from nick 627 00:29:52,600 --> 00:29:51,049 lopez and this is what kind of 628 00:29:55,090 --> 00:29:52,610 temperatures do you predict you'll see 629 00:29:59,470 --> 00:29:55,100 during entry based on your wind tunnel 630 00:30:01,510 --> 00:29:59,480 testing well we don't get up to the 631 00:30:05,080 --> 00:30:01,520 actual temperatures that we're gonna see 632 00:30:07,149 --> 00:30:05,090 in in flight in the wind tunnel test but 633 00:30:09,159 --> 00:30:07,159 for eft-1 we're predicting a peak 634 00:30:11,409 --> 00:30:09,169 surface temperature of around 4000 635 00:30:14,200 --> 00:30:11,419 degrees Fahrenheit that's two times the 636 00:30:16,930 --> 00:30:14,210 temperature of molten lava and that's 637 00:30:18,490 --> 00:30:16,940 just for our Orion's first flight test 638 00:30:21,430 --> 00:30:18,500 which isn't going to completely stress 639 00:30:23,649 --> 00:30:21,440 the system as as far as Orion will once 640 00:30:25,690 --> 00:30:23,659 we actually dry Orion's real missions 641 00:30:27,190 --> 00:30:25,700 out to the moon and beyond for those 642 00:30:30,610 --> 00:30:27,200 missions we're going to be seeing peak 643 00:30:37,299 --> 00:30:30,620 surface temperatures upwards of 5,000 to 644 00:30:38,649 --> 00:30:37,309 50 to 100 degrees Fahrenheit so that 645 00:30:41,710 --> 00:30:38,659 brings up another question if it gotten 646 00:30:44,560 --> 00:30:41,720 from Philip online and he has how can 647 00:30:48,330 --> 00:30:44,570 the module be adapted for finish they 648 00:30:51,220 --> 00:30:48,340 need to change before the next spikes 649 00:30:53,799 --> 00:30:51,230 certain parts the vehicle or have 650 00:30:55,149 --> 00:30:53,809 already changed between the first flight 651 00:30:58,990 --> 00:30:55,159 test and what we're going to be flying 652 00:31:01,180 --> 00:30:59,000 on future missions but the material that 653 00:31:02,169 --> 00:31:01,190 surrounds the vehicle we call it it's 654 00:31:05,230 --> 00:31:02,179 thermal protection 655 00:31:07,090 --> 00:31:05,240 that's what protects it from those high 656 00:31:09,249 --> 00:31:07,100 temperatures on the surface it's an 657 00:31:11,590 --> 00:31:09,259 insulated layer it's also designed to 658 00:31:15,100 --> 00:31:11,600 burn away and take that energy away from 659 00:31:17,159 --> 00:31:15,110 the surface that thickness of that 660 00:31:20,739 --> 00:31:17,169 material can change depending on your on 661 00:31:23,169 --> 00:31:20,749 your mission and then also we'll learn a 662 00:31:25,509 --> 00:31:23,179 lot from the excavation flight test-1 or 663 00:31:27,369 --> 00:31:25,519 Ryan's first flight test and that will 664 00:31:29,919 --> 00:31:27,379 feed into design for the future flight 665 00:31:32,200 --> 00:31:29,929 tests we might need to adjust certain 666 00:31:35,320 --> 00:31:32,210 thicknesses or adjust what material is 667 00:31:36,639 --> 00:31:35,330 used for certain regions and those are 668 00:31:38,950 --> 00:31:36,649 the design changes that will go into 669 00:31:43,480 --> 00:31:38,960 between the first flight test and the 670 00:31:46,180 --> 00:31:43,490 second flight sighs great it looks like 671 00:31:48,549 --> 00:31:46,190 we've got the vehicle touched down now 672 00:31:52,720 --> 00:31:48,559 on the desert in Yuma everything looking 673 00:31:55,210 --> 00:31:52,730 good - yes if you see this I'm assuming 674 00:31:58,049 --> 00:31:55,220 Brad's got the shot you see two of the 675 00:32:02,259 --> 00:31:58,059 three parachutes and they're just 676 00:32:03,669 --> 00:32:02,269 starting now starting to deflate and 677 00:32:06,999 --> 00:32:03,679 things that the ground winds here today 678 00:32:09,519 --> 00:32:07,009 are in the seven eight nine not range 679 00:32:11,499 --> 00:32:09,529 and these parachutes are very effective 680 00:32:13,989 --> 00:32:11,509 and so one of the things that we have to 681 00:32:16,060 --> 00:32:13,999 do is make sure we get them deflated and 682 00:32:18,609 --> 00:32:16,070 there these the last two are hanging on 683 00:32:21,580 --> 00:32:18,619 for a little bit but the vehicles down 684 00:32:23,230 --> 00:32:21,590 it was a good test and I saw the for 685 00:32:26,529 --> 00:32:23,240 debate cover we obviously had a good 686 00:32:30,820 --> 00:32:26,539 clean separation it's down on the ground 687 00:32:34,060 --> 00:32:30,830 already yeah so what what would be 688 00:32:36,009 --> 00:32:34,070 happening now if this were the the test 689 00:32:38,200 --> 00:32:36,019 flight in December and we were on the 690 00:32:40,779 --> 00:32:38,210 ocean what what would the recovery team 691 00:32:44,950 --> 00:32:40,789 be doing the recovery team once the 692 00:32:48,700 --> 00:32:44,960 vehicles down and once any all the other 693 00:32:52,180 --> 00:32:48,710 objects like are clear so they know that 694 00:32:55,509 --> 00:32:52,190 there's no hazards the recovery crews 695 00:32:57,999 --> 00:32:55,519 will take off out of the the Navy ship 696 00:32:59,470 --> 00:32:58,009 that's in the in the landing area and 697 00:33:02,680 --> 00:32:59,480 we'll be heading out in some small boats 698 00:33:05,049 --> 00:33:02,690 and zodiacs to go and recover the for 699 00:33:07,239 --> 00:33:05,059 debate cover and then go and recover the 700 00:33:11,279 --> 00:33:07,249 the vehicle itself and so they'll come 701 00:33:14,019 --> 00:33:11,289 out to it in the boats and attach some 702 00:33:15,890 --> 00:33:14,029 flotation to that the vehicle floats on 703 00:33:17,810 --> 00:33:15,900 its own but some extra 704 00:33:20,060 --> 00:33:17,820 device is dead just to help stabilize it 705 00:33:21,310 --> 00:33:20,070 and prepare to pull it back into the 706 00:33:24,350 --> 00:33:21,320 well deck of the ship 707 00:33:27,890 --> 00:33:24,360 but the they hold for a few minutes just 708 00:33:30,380 --> 00:33:27,900 like our test team holds here the the 709 00:33:33,590 --> 00:33:30,390 mortar deployed parachutes have lids on 710 00:33:35,300 --> 00:33:33,600 top of them and and so and the to drill 711 00:33:38,660 --> 00:33:35,310 mortars for example are about the size 712 00:33:41,420 --> 00:33:38,670 of a nice big trash can and you've got 713 00:33:43,790 --> 00:33:41,430 to let the lids from those parachutes 714 00:33:45,980 --> 00:33:43,800 get out of the air and get down on the 715 00:33:48,320 --> 00:33:45,990 ground so that you don't have to worry 716 00:33:49,880 --> 00:33:48,330 about a risk for the recovery crew to 717 00:33:52,340 --> 00:33:49,890 have one of these things come falling 718 00:33:55,190 --> 00:33:52,350 out of this guy so all these smaller 719 00:33:56,960 --> 00:33:55,200 parachutes and parts have to we verify 720 00:34:00,170 --> 00:33:56,970 that they're down on the ground using 721 00:34:10,610 --> 00:34:00,180 radar and an optics and then we go out 722 00:34:16,010 --> 00:34:10,620 and start recovering the vehicle one 723 00:34:18,139 --> 00:34:16,020 more question and we've got are the 724 00:34:22,190 --> 00:34:18,149 parachutes usable in any type of weather 725 00:34:24,649 --> 00:34:22,200 or condition yeah actually they are I 726 00:34:28,460 --> 00:34:24,659 mean they would we would not 727 00:34:31,340 --> 00:34:28,470 intentionally land in a bad weather 728 00:34:34,280 --> 00:34:31,350 situation but the parachutes themselves 729 00:34:38,360 --> 00:34:34,290 will will operate you know they have 730 00:34:40,070 --> 00:34:38,370 temperature restrictions that you know 731 00:34:42,710 --> 00:34:40,080 you don't want to land you don't want to 732 00:34:44,240 --> 00:34:42,720 put them out too hot that's why we have 733 00:34:47,510 --> 00:34:44,250 the the thermal protection system out 734 00:34:49,550 --> 00:34:47,520 there but outside of that on a on a 735 00:34:51,280 --> 00:34:49,560 cloudy day or a rainy day they would 736 00:34:53,540 --> 00:34:51,290 still they would they would be fine 737 00:34:58,160 --> 00:34:53,550 they'll still inflate and do there and 738 00:34:59,600 --> 00:34:58,170 do their function okay well I think 739 00:35:01,490 --> 00:34:59,610 that's just about all we have time for 740 00:35:04,190 --> 00:35:01,500 but before we go I wanted to do to get 741 00:35:05,690 --> 00:35:04,200 you to tell us about what's left to test 742 00:35:07,160 --> 00:35:05,700 now I know we've got another test coming 743 00:35:10,280 --> 00:35:07,170 up in August what we'll be looking at 744 00:35:13,550 --> 00:35:10,290 then and then in our August test will 745 00:35:16,220 --> 00:35:13,560 well first there will plan to do a what 746 00:35:17,510 --> 00:35:16,230 we a to parachute main test we're gonna 747 00:35:20,330 --> 00:35:17,520 simulate one of our main parachute 748 00:35:21,860 --> 00:35:20,340 failures we look at some of our other 749 00:35:25,070 --> 00:35:21,870 design improvements we're putting in the 750 00:35:27,110 --> 00:35:25,080 system and and if we learn anything as 751 00:35:28,850 --> 00:35:27,120 we look at the hardware today and over 752 00:35:31,670 --> 00:35:28,860 the next couple of weeks it needs to 753 00:35:33,620 --> 00:35:31,680 worked into the test in August we'll 754 00:35:36,680 --> 00:35:33,630 blend that in and then we have two more 755 00:35:39,320 --> 00:35:36,690 after that that complete our development 756 00:35:41,150 --> 00:35:39,330 series and once we're done with those 757 00:35:43,940 --> 00:35:41,160 we'll take all of the lessons that we've 758 00:35:47,000 --> 00:35:43,950 learned and start building the final 759 00:35:52,130 --> 00:35:47,010 design that will go into the vehicle for 760 00:35:53,960 --> 00:35:52,140 em1 and for our future human missions we 761 00:35:56,600 --> 00:35:53,970 can't wait to see all of that I think 762 00:35:58,130 --> 00:35:56,610 we're gonna wrap up there so thanks so 763 00:35:59,900 --> 00:35:58,140 much for joining us for the Hangout and 764 00:36:02,360 --> 00:35:59,910 for sending in your questions they were 765 00:36:03,650 --> 00:36:02,370 great and especially thanks to sue and 766 00:36:07,930 --> 00:36:03,660 Molly for taking time to talk with us 767 00:36:12,080 --> 00:36:10,370 progress that Orion's been making this 768 00:36:13,790 --> 00:36:12,090 year and the preparations for December's 769 00:36:15,350 --> 00:36:13,800 launch as well as some of what the Space 770 00:36:17,660 --> 00:36:15,360 Launch System and ground systems 771 00:36:19,370 --> 00:36:17,670 development operation programs have been
