1 00:00:07,590 --> 00:00:19,269 [Music] 2 00:00:23,590 --> 00:00:20,870 you're looking at a live view of the 3 00:00:26,310 --> 00:00:23,600 spacex falcon 9 rocket and cargo dragon 4 00:00:27,910 --> 00:00:26,320 at launch complex 39a set to lift off 5 00:00:29,349 --> 00:00:27,920 this afternoon to the international 6 00:00:31,189 --> 00:00:29,359 space station 7 00:00:33,030 --> 00:00:31,199 good afternoon and welcome to nasa's 8 00:00:35,350 --> 00:00:33,040 kennedy space center in florida i'm 9 00:00:36,790 --> 00:00:35,360 megan cruz with nasa communications 10 00:00:39,750 --> 00:00:36,800 today's cargo mission known as 11 00:00:41,990 --> 00:00:39,760 commercial resupply services mission 22 12 00:00:44,389 --> 00:00:42,000 is scheduled to launch at 1 29 pm 13 00:00:46,549 --> 00:00:44,399 eastern time it will be the second 14 00:00:49,350 --> 00:00:46,559 resupply mission to the space station on 15 00:00:50,950 --> 00:00:49,360 the upgraded cargo dragon spacecraft we 16 00:00:52,869 --> 00:00:50,960 will show you some of the incredible 17 00:00:56,229 --> 00:00:52,879 technology headed to space today 18 00:00:59,270 --> 00:00:56,239 including brand new solar arrays to give 19 00:01:01,189 --> 00:00:59,280 the station a power boost but first we 20 00:01:04,469 --> 00:01:01,199 are really excited to be simulcasting 21 00:01:06,870 --> 00:01:04,479 today's live coverage on nasa tv and the 22 00:01:08,310 --> 00:01:06,880 spacex webcast with our partners based 23 00:01:10,230 --> 00:01:08,320 at the company's headquarters in 24 00:01:12,789 --> 00:01:10,240 hawthorne california let's bring in 25 00:01:14,469 --> 00:01:12,799 shiva bharavaj now shiva it's so nice to 26 00:01:16,950 --> 00:01:14,479 have you with us today 27 00:01:18,870 --> 00:01:16,960 thanks megan it's really exciting to be 28 00:01:21,270 --> 00:01:18,880 covering today's mission in partnership 29 00:01:22,950 --> 00:01:21,280 with nasa it's the fifth dragon flight 30 00:01:25,270 --> 00:01:22,960 to the international space station since 31 00:01:27,590 --> 00:01:25,280 may 2020 with many more planned for the 32 00:01:29,670 --> 00:01:27,600 upcoming year and as you mentioned this 33 00:01:31,990 --> 00:01:29,680 will be the second cargo resupply 34 00:01:34,950 --> 00:01:32,000 mission for our upgraded dragon this 35 00:01:37,030 --> 00:01:34,960 cargo vehicle will be joining the crew 2 36 00:01:38,789 --> 00:01:37,040 vehicle on orbit making it just the 37 00:01:40,630 --> 00:01:38,799 third time that we've had two dragons 38 00:01:42,710 --> 00:01:40,640 docked at the space station 39 00:01:45,270 --> 00:01:42,720 now you're looking at a live view of a 40 00:01:46,789 --> 00:01:45,280 brand new falcon 9 booster this is 41 00:01:48,950 --> 00:01:46,799 actually the first new booster that 42 00:01:51,990 --> 00:01:48,960 we're using this year and the vehicle 43 00:01:55,109 --> 00:01:52,000 stands 229 feet tall or slightly taller 44 00:01:57,830 --> 00:01:55,119 than a 21 building now falcon 9 is a 45 00:02:00,149 --> 00:01:57,840 reusable two-stage rocket designed and 46 00:02:02,149 --> 00:02:00,159 manufactured by spacex for the reliable 47 00:02:05,030 --> 00:02:02,159 and safe transport of both people and 48 00:02:07,030 --> 00:02:05,040 payloads into earth orbit and beyond 49 00:02:09,749 --> 00:02:07,040 this falcon 9 rolled out to the pad and 50 00:02:12,790 --> 00:02:09,759 went vertical on tuesday june 1st around 51 00:02:14,390 --> 00:02:12,800 3 p.m eastern time and actually 52 00:02:16,630 --> 00:02:14,400 just before the program started at 53 00:02:18,869 --> 00:02:16,640 around t minus 35 minutes we began 54 00:02:20,790 --> 00:02:18,879 loading propellants onto falcon 9. 55 00:02:23,750 --> 00:02:20,800 falcon 9 uses two propellants the first 56 00:02:25,830 --> 00:02:23,760 of those is a fuel a refined form of 57 00:02:28,470 --> 00:02:25,840 kerosene known as rp1 or rocket 58 00:02:31,110 --> 00:02:28,480 propellant one and for our oxidizer we 59 00:02:33,750 --> 00:02:31,120 use super chilled liquid oxygen referred 60 00:02:35,509 --> 00:02:33,760 to as locks we chill the locks well 61 00:02:37,750 --> 00:02:35,519 below the boiling point which helps 62 00:02:40,070 --> 00:02:37,760 increase its density so we can load more 63 00:02:42,229 --> 00:02:40,080 of it into the first and second stages 64 00:02:44,790 --> 00:02:42,239 now to start the engines we also need an 65 00:02:47,750 --> 00:02:44,800 ignition source for that falcon 9 uses a 66 00:02:50,070 --> 00:02:47,760 chemical igniter called t-tab you'll see 67 00:02:51,670 --> 00:02:50,080 a characteristic green spark around the 68 00:02:54,390 --> 00:02:51,680 t-minus zero 69 00:02:56,550 --> 00:02:54,400 mark right before the rocket takes off 70 00:02:58,390 --> 00:02:56,560 now the bottom two thirds of the vehicle 71 00:03:00,229 --> 00:02:58,400 is what we refer to as the first stage 72 00:03:01,910 --> 00:03:00,239 its objective is to accelerate the 73 00:03:03,990 --> 00:03:01,920 vehicle through the earth's atmosphere 74 00:03:06,070 --> 00:03:04,000 to space and then it'll separate from 75 00:03:08,229 --> 00:03:06,080 the rest of the rocket today we will be 76 00:03:10,070 --> 00:03:08,239 attempting to recover this first stage 77 00:03:11,910 --> 00:03:10,080 on our drone ship named of course i 78 00:03:13,670 --> 00:03:11,920 still love you that's stationed out in 79 00:03:15,910 --> 00:03:13,680 the atlantic ocean and if you've been 80 00:03:18,070 --> 00:03:15,920 keeping town at home if we successfully 81 00:03:20,949 --> 00:03:18,080 land the falcon 9 today it'll mark our 82 00:03:22,390 --> 00:03:20,959 86th successful landing of an orbital 83 00:03:24,070 --> 00:03:22,400 class rocket 84 00:03:26,789 --> 00:03:24,080 now on top of the first stage we have 85 00:03:29,350 --> 00:03:26,799 falcon 9's second stage it has a single 86 00:03:31,830 --> 00:03:29,360 merlin vacuum or mvac engine that 87 00:03:33,430 --> 00:03:31,840 ignites after the first stage separates 88 00:03:35,750 --> 00:03:33,440 the second stage is ultimately what will 89 00:03:37,670 --> 00:03:35,760 carry dragon into its intended orbit 90 00:03:39,589 --> 00:03:37,680 allowing dragon to then separate and 91 00:03:40,949 --> 00:03:39,599 then eventually for it to continue with 92 00:03:43,350 --> 00:03:40,959 its rendezvous to the international 93 00:03:45,350 --> 00:03:43,360 space station now finally at the very 94 00:03:47,750 --> 00:03:45,360 top of the rocket is the dragon 95 00:03:49,990 --> 00:03:47,760 spacecraft dragon was designed from the 96 00:03:51,990 --> 00:03:50,000 beginning to be reused this new version 97 00:03:53,910 --> 00:03:52,000 of dragon was designed for up to five 98 00:03:56,149 --> 00:03:53,920 flights while the previous version could 99 00:03:58,550 --> 00:03:56,159 only support three just like today's 100 00:04:00,710 --> 00:03:58,560 falcon 9 we're flying a brand new dragon 101 00:04:02,630 --> 00:04:00,720 spacecraft which will hope to fly again 102 00:04:04,789 --> 00:04:02,640 in the future a bit later on in the 103 00:04:06,869 --> 00:04:04,799 broadcast i'll share some details on the 104 00:04:08,949 --> 00:04:06,879 advancements we're making with reusing 105 00:04:11,429 --> 00:04:08,959 certain aspects of the vehicle 106 00:04:14,070 --> 00:04:11,439 now today is a cargo mission and we are 107 00:04:15,990 --> 00:04:14,080 delivering nearly 7 000 pounds of cargo 108 00:04:17,830 --> 00:04:16,000 to the international space station that 109 00:04:19,509 --> 00:04:17,840 includes critical material to support 110 00:04:21,590 --> 00:04:19,519 dozens of science and research 111 00:04:23,510 --> 00:04:21,600 investigations that'll happen on board 112 00:04:25,510 --> 00:04:23,520 the orbiting laboratory to this day 113 00:04:27,430 --> 00:04:25,520 dragon remains the only spacecraft 114 00:04:29,110 --> 00:04:27,440 currently flying that's capable of 115 00:04:32,070 --> 00:04:29,120 transporting significant amounts of 116 00:04:33,990 --> 00:04:32,080 cargo to and from planet earth we'll get 117 00:04:36,070 --> 00:04:34,000 a little more into detail on what some 118 00:04:38,390 --> 00:04:36,080 of that research is later on in today's 119 00:04:40,390 --> 00:04:38,400 webcast but first why don't we check in 120 00:04:41,990 --> 00:04:40,400 at the launch site kennedy space center 121 00:04:42,710 --> 00:04:42,000 with marie marie how are things over 122 00:04:44,790 --> 00:04:42,720 there 123 00:04:46,469 --> 00:04:44,800 hey shiva nice to see you uh things are 124 00:04:48,870 --> 00:04:46,479 looking actually much better than they 125 00:04:50,390 --> 00:04:48,880 were just an hour ago at the launch site 126 00:04:53,270 --> 00:04:50,400 if we could take a live look again at 127 00:04:55,830 --> 00:04:53,280 launch complex 39a you can see some 128 00:04:58,469 --> 00:04:55,840 cumulus clouds in the area weather still 129 00:05:00,790 --> 00:04:58,479 standing at about 60 percent favorable 130 00:05:03,189 --> 00:05:00,800 for launch and it's been trending in a 131 00:05:05,430 --> 00:05:03,199 better direction in fact just an hour 132 00:05:07,510 --> 00:05:05,440 ago we had no go conditions for weather 133 00:05:08,710 --> 00:05:07,520 we were in violation of the cumulus 134 00:05:10,870 --> 00:05:08,720 cloud rule 135 00:05:12,870 --> 00:05:10,880 but the threat seems to be diminishing 136 00:05:14,870 --> 00:05:12,880 at this hour uh the weather teams are 137 00:05:16,629 --> 00:05:14,880 watching a couple of cells south of uh 138 00:05:18,390 --> 00:05:16,639 patrick space force base that's a little 139 00:05:19,909 --> 00:05:18,400 bit south of the cape here and they are 140 00:05:22,070 --> 00:05:19,919 headed north but 141 00:05:24,310 --> 00:05:22,080 it's looking like it's not going to be a 142 00:05:26,390 --> 00:05:24,320 show stopper so again trending in the 143 00:05:27,749 --> 00:05:26,400 right direction the threat of lightning 144 00:05:30,390 --> 00:05:27,759 remains low 145 00:05:31,990 --> 00:05:30,400 so we are 60 percent go for weather um 146 00:05:33,670 --> 00:05:32,000 and that's been most of the chatter that 147 00:05:35,350 --> 00:05:33,680 we've heard uh so far in these last 148 00:05:37,590 --> 00:05:35,360 couple of hours 149 00:05:40,390 --> 00:05:37,600 uh technically speaking we have heard uh 150 00:05:41,909 --> 00:05:40,400 spacex working no major issues and again 151 00:05:43,909 --> 00:05:41,919 we're looking live at the launch pad 152 00:05:46,390 --> 00:05:43,919 there you can see some of that liquid 153 00:05:49,189 --> 00:05:46,400 oxygen venting off of the first stage 154 00:05:51,029 --> 00:05:49,199 falcon 9 booster one other really cool 155 00:05:53,830 --> 00:05:51,039 thing about this first stage booster if 156 00:05:56,309 --> 00:05:53,840 spacex successfully recovers it and 157 00:05:59,510 --> 00:05:56,319 refurbishes it this is the same booster 158 00:06:01,350 --> 00:05:59,520 slated to launch uh for the next four 159 00:06:03,990 --> 00:06:01,360 astronauts to the international space 160 00:06:07,029 --> 00:06:04,000 station in october uh those will be nasa 161 00:06:09,830 --> 00:06:07,039 astronauts raja chari thomas marshburn 162 00:06:12,469 --> 00:06:09,840 kayla baron and european space agency 163 00:06:14,629 --> 00:06:12,479 astronaut matthias maurer so nasa's 164 00:06:16,710 --> 00:06:14,639 commercial crew program folks watching 165 00:06:19,270 --> 00:06:16,720 this mission closely with a particular 166 00:06:21,110 --> 00:06:19,280 interest in that first stage booster 167 00:06:23,110 --> 00:06:21,120 so we have fueling again well underway 168 00:06:25,510 --> 00:06:23,120 that began on the first stage at t minus 169 00:06:27,430 --> 00:06:25,520 35 minutes uh we're standing by for 170 00:06:29,830 --> 00:06:27,440 fueling on the second stage at t minus 171 00:06:31,909 --> 00:06:29,840 16 minutes and then as we move a little 172 00:06:34,070 --> 00:06:31,919 bit closer to launch the falcon 9 173 00:06:36,390 --> 00:06:34,080 pre-launch engine chill will begin at t 174 00:06:39,270 --> 00:06:36,400 minus seven minutes followed by the 175 00:06:41,189 --> 00:06:39,280 transition to internal power at t minus 176 00:06:42,790 --> 00:06:41,199 five minutes and that period those last 177 00:06:45,189 --> 00:06:42,800 five minutes before launch are what we 178 00:06:47,189 --> 00:06:45,199 call terminal count and then as we close 179 00:06:49,589 --> 00:06:47,199 in on that final minute before launch 180 00:06:52,150 --> 00:06:49,599 the propellant tanks will be pressurized 181 00:06:54,629 --> 00:06:52,160 for flight uh the space spacex launch 182 00:06:56,870 --> 00:06:54,639 director frank messina will verify 183 00:06:58,469 --> 00:06:56,880 whether the team is go for launch and 184 00:07:02,390 --> 00:06:58,479 finally uh we'll be standing by for 185 00:07:04,230 --> 00:07:02,400 liftoff at 129 and 15 seconds pm 186 00:07:06,309 --> 00:07:04,240 eastern daylight time 187 00:07:08,070 --> 00:07:06,319 uh and falcon 9 has just that single 188 00:07:09,990 --> 00:07:08,080 second to launch today in order to 189 00:07:12,710 --> 00:07:10,000 rendezvous and dock to the space station 190 00:07:14,790 --> 00:07:12,720 as scheduled uh that is tracking for 191 00:07:17,270 --> 00:07:14,800 approximately 5 a.m eastern time 192 00:07:18,790 --> 00:07:17,280 saturday morning june 5th so we'll 193 00:07:20,309 --> 00:07:18,800 continue to keep an eye on the weather 194 00:07:22,230 --> 00:07:20,319 and give you an update as we get a 195 00:07:24,469 --> 00:07:22,240 little bit closer to liftoff for now 196 00:07:26,070 --> 00:07:24,479 megan back to you murray thank you all 197 00:07:27,909 --> 00:07:26,080 right as promised it's now time to check 198 00:07:29,909 --> 00:07:27,919 out some of the fascinating payloads 199 00:07:31,430 --> 00:07:29,919 packed inside dragon today we'll first 200 00:07:42,629 --> 00:07:31,440 look at some of the science experiments 201 00:07:45,189 --> 00:07:44,150 more than 900 pounds of research and 202 00:07:47,430 --> 00:07:45,199 supplies are launching to the 203 00:07:49,189 --> 00:07:47,440 international space station on spacex's 204 00:07:51,430 --> 00:07:49,199 22nd commercial resupply services 205 00:07:54,629 --> 00:07:51,440 mission including several

all 285 00:10:24,230 --> 00:10:22,160 the payloads on this mission that are 286 00:10:25,509 --> 00:10:24,240 sponsored by the iss national lab and to 287 00:10:26,710 --> 00:10:25,519 learn about current opportunities to 288 00:10:28,150 --> 00:10:26,720 become part of the space station 289 00:10:31,070 --> 00:10:28,160 research community please visit 290 00:10:34,389 --> 00:10:31,080 issnationallab.org 291 00:10:35,910 --> 00:10:34,399 [Music] 292 00:10:37,910 --> 00:10:35,920 now you heard in that video about an 293 00:10:39,590 --> 00:10:37,920 experiment with cotton let's take a 294 00:10:42,550 --> 00:10:39,600 closer look at that one because you 295 00:10:43,910 --> 00:10:42,560 might be amused by its name tick tock 296 00:10:46,150 --> 00:10:43,920 and no it has nothing to do with the 297 00:10:47,670 --> 00:10:46,160 social media app tic tac here to help us 298 00:10:49,750 --> 00:10:47,680 understand the name and why this 299 00:10:52,230 --> 00:10:49,760 research is so significant is principal 300 00:10:53,590 --> 00:10:52,240 investigator dr simon gilroy dr gilroy 301 00:10:55,269 --> 00:10:53,600 thank you so much for joining us my 302 00:10:57,030 --> 00:10:55,279 pleasure to be here well obviously we've 303 00:10:59,030 --> 00:10:57,040 said tick tock your tick tock is 304 00:11:00,949 --> 00:10:59,040 different from the tick tock most of us 305 00:11:03,910 --> 00:11:00,959 know so what is your tick tock yep yep 306 00:11:06,150 --> 00:11:03,920 we definitely came second so um 307 00:11:08,470 --> 00:11:06,160 it's a acronym for targeting improved 308 00:11:09,590 --> 00:11:08,480 cotton through orbital cultivation and 309 00:11:11,269 --> 00:11:09,600 what does that mean what are you trying 310 00:11:13,190 --> 00:11:11,279 to do here uh so we've got the 311 00:11:15,190 --> 00:11:13,200 opportunity to understand a little bit 312 00:11:16,710 --> 00:11:15,200 more about how cotton grows 313 00:11:18,150 --> 00:11:16,720 by growing on the space station and 314 00:11:19,829 --> 00:11:18,160 doing you know the kind of experiments 315 00:11:20,790 --> 00:11:19,839 you just simply can't do when you're on 316 00:11:22,790 --> 00:11:20,800 the earth 317 00:11:24,389 --> 00:11:22,800 and how are you actually going to grow 318 00:11:25,990 --> 00:11:24,399 cotton on the space station and how much 319 00:11:27,829 --> 00:11:26,000 of it are you trying to grow right so 320 00:11:29,829 --> 00:11:27,839 cotton gets to be a really big plant so 321 00:11:32,150 --> 00:11:29,839 we're not going to grow full-sized 322 00:11:34,389 --> 00:11:32,160 cotton plants you know six foot tall 323 00:11:36,470 --> 00:11:34,399 this is actually the chamber that we are 324 00:11:37,750 --> 00:11:36,480 going to send up so there are 12 of 325 00:11:39,910 --> 00:11:37,760 these which are going to go up onto the 326 00:11:42,310 --> 00:11:39,920 space station each one of them has four 327 00:11:43,910 --> 00:11:42,320 cotton seeds in there and we set it up 328 00:11:46,710 --> 00:11:43,920 so they'll actually germinate while 329 00:11:48,710 --> 00:11:46,720 they're on the station and they'll fill 330 00:11:50,949 --> 00:11:48,720 this chamber after about six days wow 331 00:11:52,949 --> 00:11:50,959 that's amazing and how so what exactly 332 00:11:54,790 --> 00:11:52,959 are you trying to figure out in space 333 00:11:57,590 --> 00:11:54,800 that can hopefully help us here on earth 334 00:11:59,509 --> 00:11:57,600 uh yeah so cotton is an incredibly 335 00:12:00,949 --> 00:11:59,519 thirsty crop it uses tremendous amount 336 00:12:02,629 --> 00:12:00,959 of water hundreds of gallons just to 337 00:12:06,310 --> 00:12:02,639 make one t-shirt 338 00:12:08,150 --> 00:12:06,320 uh and it also uses a lot of inputs like 339 00:12:09,430 --> 00:12:08,160 nutrients that the farms have to add 340 00:12:12,069 --> 00:12:09,440 pesticides 341 00:12:13,030 --> 00:12:12,079 uh and a lot of those those features of 342 00:12:15,269 --> 00:12:13,040 cotton 343 00:12:17,030 --> 00:12:15,279 they are root traits so they're things 344 00:12:19,190 --> 00:12:17,040 that you know the root takes up the 345 00:12:20,870 --> 00:12:19,200 water the root takes up the nutrients 346 00:12:22,710 --> 00:12:20,880 and so what we're hoping to do on the 347 00:12:24,870 --> 00:12:22,720 space station is learn a little bit more 348 00:12:27,269 --> 00:12:24,880 about how that root system develops with 349 00:12:29,030 --> 00:12:27,279 the idea that if we can very 350 00:12:31,430 --> 00:12:29,040 specifically for us understand how 351 00:12:33,350 --> 00:12:31,440 gravity directs that that root system to 352 00:12:35,350 --> 00:12:33,360 grow and spread throughout the soil we 353 00:12:37,350 --> 00:12:35,360 might be able to target features there 354 00:12:39,350 --> 00:12:37,360 that then we can give that information 355 00:12:41,269 --> 00:12:39,360 to breeders who will then be able to go 356 00:12:43,350 --> 00:12:41,279 down the road of improving cotton yeah 357 00:12:45,030 --> 00:12:43,360 basically to make better cotton right 358 00:12:46,710 --> 00:12:45,040 yeah absolutely that's amazing how does 359 00:12:48,790 --> 00:12:46,720 it feel to have science going up to 360 00:12:51,430 --> 00:12:48,800 space today i mean it is it is an 361 00:12:52,949 --> 00:12:51,440 amazing opportunity uh we've shot a 362 00:12:54,069 --> 00:12:52,959 couple of experiments up to the space 363 00:12:57,269 --> 00:12:54,079 station before 364 00:12:59,190 --> 00:12:57,279 every single time it's it's it's it's a 365 00:13:00,790 --> 00:12:59,200 rush to see your stuff going up on the 366 00:13:01,990 --> 00:13:00,800 on the rocket i got to ask you why 367 00:13:02,790 --> 00:13:02,000 cotton 368 00:13:03,990 --> 00:13:02,800 um 369 00:13:05,350 --> 00:13:04,000 cotton 370 00:13:07,110 --> 00:13:05,360 partly because 371 00:13:08,790 --> 00:13:07,120 we have the opportunity to understand a 372 00:13:11,030 --> 00:13:08,800 little bit more about a really important 373 00:13:13,750 --> 00:13:11,040 economic crop with a big environmental 374 00:13:15,190 --> 00:13:13,760 footprint on earth so using the 375 00:13:16,790 --> 00:13:15,200 facilities of the space station to do 376 00:13:17,750 --> 00:13:16,800 things that we just could never do on 377 00:13:18,870 --> 00:13:17,760 earth 378 00:13:20,550 --> 00:13:18,880 and also 379 00:13:21,910 --> 00:13:20,560 there have been a lot of plant biology 380 00:13:24,069 --> 00:13:21,920 experiments done by a lot of great 381 00:13:27,350 --> 00:13:24,079 researchers on the station but on a 382 00:13:28,389 --> 00:13:27,360 relatively few species of plants and so 383 00:13:30,710 --> 00:13:28,399 cotton is going to give us this 384 00:13:32,310 --> 00:13:30,720 fantastic tool to ask 385 00:13:34,310 --> 00:13:32,320 how different is it from these other 386 00:13:35,990 --> 00:13:34,320 plants and how similar what do all 387 00:13:38,389 --> 00:13:36,000 plants do when they're in space and what 388 00:13:40,230 --> 00:13:38,399 does very specifically particular to 389 00:13:41,430 --> 00:13:40,240 each kind of plant doctor i'm so excited 390 00:13:42,790 --> 00:13:41,440 to see what you find out thank you so 391 00:13:44,629 --> 00:13:42,800 much for joining us today great thank 392 00:13:46,230 --> 00:13:44,639 you thank you and one more notable 393 00:13:48,150 --> 00:13:46,240 payload i wanted to tell you about is 394 00:13:50,389 --> 00:13:48,160 the first satellite developed by the 395 00:13:52,230 --> 00:13:50,399 island nation of mauritius that's east 396 00:13:54,550 --> 00:13:52,240 of madagascar if you didn't know that 397 00:13:56,550 --> 00:13:54,560 it's cubesat which is a small satellite 398 00:13:58,150 --> 00:13:56,560 about this big will photograph the 399 00:13:59,750 --> 00:13:58,160 region and conduct experimental 400 00:14:00,870 --> 00:13:59,760 communication with other islands so 401 00:14:02,710 --> 00:14:00,880 really cool there 402 00:14:04,389 --> 00:14:02,720 again you know just really fascinating 403 00:14:08,949 --> 00:14:04,399 payloads on today's mission now let's 404 00:14:13,910 --> 00:14:11,590 thanks megan uh we're just under t minus 405 00:14:16,150 --> 00:14:13,920 15 minutes and counting to the liftoff 406 00:14:18,069 --> 00:14:16,160 of a falcon 9 carrying cargo dragon on 407 00:14:20,230 --> 00:14:18,079 the next commercial resupply mission to 408 00:14:22,069 --> 00:14:20,240 the international space station now as 409 00:14:24,389 --> 00:14:22,079 we talked about earlier dragon was 410 00:14:26,949 --> 00:14:24,399 designed with reusability in mind to 411 00:14:29,030 --> 00:14:26,959 date nine of our cargo resupply missions 412 00:14:31,110 --> 00:14:29,040 have launched on flight proven dragon 413 00:14:33,430 --> 00:14:31,120 spacecraft and while we have a history 414 00:14:35,430 --> 00:14:33,440 of re-flying cargo vehicles and now crew 415 00:14:38,389 --> 00:14:35,440 vehicles with the successful launch of 416 00:14:39,910 --> 00:14:38,399 crew 2 as of today we will also reuse 417 00:14:41,910 --> 00:14:39,920 dragon's heat shield structure for the 418 00:14:44,150 --> 00:14:41,920 first time the heat shield of flying 419 00:14:46,310 --> 00:14:44,160 today safely returned astronauts bob 420 00:14:48,790 --> 00:14:46,320 bankin and doug hurley to earth on the 421 00:14:50,949 --> 00:14:48,800 demo 2 mission last year usability 422 00:14:52,949 --> 00:14:50,959 allows spacex to refly the most 423 00:14:54,629 --> 00:14:52,959 expensive parts of the spacecraft and 424 00:14:57,509 --> 00:14:54,639 that in turn drives down the cost of 425 00:14:59,269 --> 00:14:57,519 space access so wild dragon today is a 426 00:15:00,949 --> 00:14:59,279 new vehicle there are a handful of 427 00:15:03,110 --> 00:15:00,959 components flying that have seen some 428 00:15:05,750 --> 00:15:03,120 space before the heat shield structure 429 00:15:07,750 --> 00:15:05,760 just being one example now speaking of 430 00:15:09,670 --> 00:15:07,760 new technologies the astronauts on board 431 00:15:11,829 --> 00:15:09,680 the international space station are 432 00:15:13,590 --> 00:15:11,839 eagerly awaiting this next delivery of 433 00:15:15,670 --> 00:15:13,600 science to keep them busy on the world's 434 00:15:17,110 --> 00:15:15,680 only orbiting laboratory we had a chance 435 00:15:18,870 --> 00:15:17,120 to catch up with a couple of them to 436 00:15:20,710 --> 00:15:18,880 hear about the work they've been doing 437 00:15:23,750 --> 00:15:20,720 since they arrived safely on the crew 2 438 00:15:26,310 --> 00:15:23,760 mission back in april 439 00:15:29,990 --> 00:15:26,320 hi everyone welcome to the international 440 00:15:33,910 --> 00:15:30,000 space station i'm aki hoshide and we're 441 00:15:35,590 --> 00:15:33,920 here doing expedition 65 and i'm megan 442 00:15:37,910 --> 00:15:35,600 macarthur one of the flight engineers 443 00:15:39,910 --> 00:15:37,920 for the mission and you probably know we 444 00:15:42,949 --> 00:15:39,920 have a cargo mission coming up real soon 445 00:15:44,150 --> 00:15:42,959 spacex 22 and i'm excited to see what 446 00:15:45,670 --> 00:15:44,160 that's going to be like i think it's 447 00:15:48,069 --> 00:15:45,680 going to affect our pace and everything 448 00:15:50,069 --> 00:15:48,079 that we've got going on aki you've seen 449 00:15:52,710 --> 00:15:50,079 this before you captured actually the 450 00:15:54,710 --> 00:15:52,720 first cargo resupply mission from dragon 451 00:15:56,629 --> 00:15:54,720 about nine years ago so tell me what was 452 00:15:59,269 --> 00:15:56,639 that like yeah nine years ago that's a 453 00:16:02,389 --> 00:15:59,279 long long time ago well that was my 454 00:16:04,629 --> 00:16:02,399 first uh time to actually capture a 455 00:16:07,189 --> 00:16:04,639 cargo vehicle with a robotic arm and so 456 00:16:08,949 --> 00:16:07,199 it was a horrifying two minutes you know 457 00:16:10,230 --> 00:16:08,959 holding my breath and trying to capture 458 00:16:12,790 --> 00:16:10,240 it without 459 00:16:14,150 --> 00:16:12,800 making any mistakes this cargo dragon 460 00:16:15,990 --> 00:16:14,160 will be actually a little bit different 461 00:16:18,550 --> 00:16:16,000 so what's different about this one this 462 00:16:20,949 --> 00:16:18,560 time it's just gonna dock so without the 463 00:16:23,990 --> 00:16:20,959 help of the robotic arm it's gonna 464 00:16:25,590 --> 00:16:24,000 automatically dock to the international 465 00:16:27,590 --> 00:16:25,600 space station of course it will be 466 00:16:29,269 --> 00:16:27,600 similar to our crude vehicle that we 467 00:16:31,430 --> 00:16:29,279 came up in so everything should look 468 00:16:33,110 --> 00:16:31,440 pretty much the same just there won't be 469 00:16:35,710 --> 00:16:33,120 people there'll be uh there'll be cargo 470 00:16:37,189 --> 00:16:35,720 and a lot of science experiments 471 00:16:39,189 --> 00:16:37,199 [Music] 472 00:16:41,030 --> 00:16:39,199 some of the science samples will arrive 473 00:16:42,949 --> 00:16:41,040 in powered payload lockers so they can 474 00:16:45,590 --> 00:16:42,959 be frozen temperatures but some of the 475 00:16:46,790 --> 00:16:45,600 samples will arrive in this cooler type 476 00:16:48,790 --> 00:16:46,800 of 477 00:16:51,110 --> 00:16:48,800 bag which is called a double cold bag 478 00:16:52,710 --> 00:16:51,120 it's a super insulated bag and we put 479 00:16:53,990 --> 00:16:52,720 ice bricks in there along with the 480 00:16:55,350 --> 00:16:54,000 samples to keep them at the right 481 00:16:59,350 --> 00:16:55,360 temperature so i'll show you what that 482 00:16:59,360 --> 00:17:02,870 oh looks like we have a stowaway 483 00:17:07,110 --> 00:17:04,630 these are the ice bricks and they can 484 00:17:09,990 --> 00:17:07,120 maintain a temperature um between minus 485 00:17:11,270 --> 00:17:10,000 32 and plus 37 celsius they're they're 486 00:17:13,270 --> 00:17:11,280 just room temperature right now or i 487 00:17:14,870 --> 00:17:13,280 wouldn't be holding them with bare hands 488 00:17:15,829 --> 00:17:14,880 but you can see we would fill that up 489 00:17:17,029 --> 00:17:15,839 with the 490 00:17:19,590 --> 00:17:17,039 ice bricks 491 00:17:21,350 --> 00:17:19,600 as well as the samples we also send 492 00:17:22,870 --> 00:17:21,360 samples home this way 493 00:17:24,309 --> 00:17:22,880 and they have a certain amount of time 494 00:17:25,909 --> 00:17:24,319 that they will stay at temperature 495 00:17:27,350 --> 00:17:25,919 before they're recovered by the team on 496 00:17:28,549 --> 00:17:27,360 the ground 497 00:17:30,070 --> 00:17:28,559 you know i'm excited about the 498 00:17:31,830 --> 00:17:30,080 tardigrades i told you about the water 499 00:17:33,990 --> 00:17:31,840 bears super excited about that they're 500 00:17:36,230 --> 00:17:34,000 little microscopic creatures that can 501 00:17:38,470 --> 00:17:36,240 survive in extreme environments and the 502 00:17:41,350 --> 00:17:38,480 um the cell science four experiment is 503 00:17:42,789 --> 00:17:41,360 looking at um how like what can we see 504 00:17:44,230 --> 00:17:42,799 by looking at their genes how do they 505 00:17:45,990 --> 00:17:44,240 survive and adapt to extreme 506 00:17:48,549 --> 00:17:46,000 environments and then the hope is that 507 00:17:50,470 --> 00:17:48,559 that information can be used to um to 508 00:17:52,230 --> 00:17:50,480 look at stress factors in humans when 509 00:17:54,310 --> 00:17:52,240 we're living in space 510 00:17:56,549 --> 00:17:54,320 another one i think is really exciting 511 00:17:58,830 --> 00:17:56,559 that has benefits both for us in space 512 00:18:01,669 --> 00:17:58,840 but also on earth is a new ultrasound 513 00:18:03,830 --> 00:18:01,679 experiment the butterfly ultrasound and 514 00:18:06,070 --> 00:18:03,840 it's looking at portable ultrasound 515 00:18:07,830 --> 00:18:06,080 technology with mobile tech some really 516 00:18:16,230 --> 00:18:07,840 exciting stuff that kind of covers a big 517 00:18:19,750 --> 00:18:17,830 and that was nasa astronaut megan 518 00:18:21,909 --> 00:18:19,760 mcarthur and jack's astronaut aki 519 00:18:23,430 --> 00:18:21,919 hoshide aboard the international space 520 00:18:24,789 --> 00:18:23,440 station and welcome into the 521 00:18:26,549 --> 00:18:24,799 international space station flight 522 00:18:28,950 --> 00:18:26,559 control room at the johnson space center 523 00:18:30,630 --> 00:18:28,960 here in houston texas the team of flight 524 00:18:32,230 --> 00:18:30,640 controllers in mission control houston 525 00:18:34,230 --> 00:18:32,240 today is being led by flight director 526 00:18:35,669 --> 00:18:34,240 rebecca wingfield the teams here in 527 00:18:37,430 --> 00:18:35,679 mission control will really jump into 528 00:18:39,510 --> 00:18:37,440 action tomorrow night into saturday 529 00:18:41,270 --> 00:18:39,520 morning as cargo dragon approaches the 530 00:18:43,350 --> 00:18:41,280 international space station and enters 531 00:18:45,270 --> 00:18:43,360 the approach ellipsoid which we like to 532 00:18:47,029 --> 00:18:45,280 think of as an imaginary sphere around 533 00:18:49,270 --> 00:18:47,039 the space station that helps us monitor 534 00:18:51,830 --> 00:18:49,280 the approach and departure of visiting 535 00:18:53,350 --> 00:18:51,840 vehicles there are currently seven crew 536 00:18:55,430 --> 00:18:53,360 members living and working aboard the 537 00:18:57,909 --> 00:18:55,440 international space station expedition 538 00:18:59,830 --> 00:18:57,919 65 consists of nasa astronauts shane 539 00:19:02,390 --> 00:18:59,840 kimbrough megan macarthur and mark 540 00:19:05,110 --> 00:19:02,400

solar arrays 546 00:19:19,430 --> 00:19:17,039 which will be installed to the 2b and 4b 547 00:19:21,510 --> 00:19:19,440 channels of the p6 truss by tomah 548 00:19:23,590 --> 00:19:21,520 pasquee and shane kimbrough over two 549 00:19:25,830 --> 00:19:23,600 spacewalks planned for june 16th and 550 00:19:27,990 --> 00:19:25,840 june 20th this will be the first of 551 00:19:30,150 --> 00:19:28,000 three deliveries of these irosa solar 552 00:19:31,830 --> 00:19:30,160 arrays there will be six in all to 553 00:19:33,990 --> 00:19:31,840 upgrade and augment the power for the 554 00:19:35,029 --> 00:19:34,000 six of eight power channels on the 555 00:19:36,470 --> 00:19:35,039 station 556 00:19:37,750 --> 00:19:36,480 as crew dragon approaches the 557 00:19:39,669 --> 00:19:37,760 international space station in the 558 00:19:41,270 --> 00:19:39,679 morning hours on june 5th nasa 559 00:19:43,669 --> 00:19:41,280 astronauts shane kimbrough and megan 560 00:19:45,750 --> 00:19:43,679 macarthur will be monitoring the arrival 561 00:19:47,350 --> 00:19:45,760 from the station's cupola and once 562 00:19:48,710 --> 00:19:47,360 dragon arrives to the station it will 563 00:19:50,470 --> 00:19:48,720 dock to the zenith port on the 564 00:19:52,470 --> 00:19:50,480 space-facing side of the station's 565 00:19:55,750 --> 00:19:52,480 harmony module and will join four other 566 00:19:59,750 --> 00:19:55,760 spacecrafts crew dragon cygnus 15 the 567 00:20:01,029 --> 00:19:59,760 soyuz ms-18 and progress 77 cargo dragon 568 00:20:02,630 --> 00:20:01,039 will remain attached to the 569 00:20:04,310 --> 00:20:02,640 international space station for about 570 00:20:06,310 --> 00:20:04,320 one month before being packed up with 571 00:20:08,149 --> 00:20:06,320 critical science and supplies and will 572 00:20:10,149 --> 00:20:08,159 splash down in the atlantic ocean for 573 00:20:12,230 --> 00:20:10,159 that science to be analyzed back here on 574 00:20:14,230 --> 00:20:12,240 earth again everything is still a go 575 00:20:15,590 --> 00:20:14,240 from here in mission control houston and 576 00:20:17,270 --> 00:20:15,600 we're looking forward to welcoming 577 00:20:19,029 --> 00:20:17,280 another vehicle to the international 578 00:20:20,710 --> 00:20:19,039 space station so for now we'll head back 579 00:20:22,789 --> 00:20:20,720 out to kennedy megan 580 00:20:24,789 --> 00:20:22,799 it is now t minus eight minutes and 581 00:20:26,789 --> 00:20:24,799 counting until liftoff of the falcon 9 582 00:20:28,470 --> 00:20:26,799 rocket and cargo dragon on the next 583 00:20:30,230 --> 00:20:28,480 resupply mission to the international 584 00:20:32,149 --> 00:20:30,240 space station now you heard courtney 585 00:20:34,230 --> 00:20:32,159 just mention the new solar arrays again 586 00:20:36,070 --> 00:20:34,240 so let's take some time to go more in 587 00:20:37,750 --> 00:20:36,080 depth about those because they're really 588 00:20:39,669 --> 00:20:37,760 important to the station and what 589 00:20:41,990 --> 00:20:39,679 happens there take a look at your screen 590 00:20:45,350 --> 00:20:42,000 now this is the first pair of the new 591 00:20:47,590 --> 00:20:45,360 boeing made iss roll out solar arrays 592 00:20:49,990 --> 00:20:47,600 known as irosa they are made up of 593 00:20:54,470 --> 00:20:50,000 compact panels you see there that roll 594 00:20:56,470 --> 00:20:54,480 open like a huge yoga mat 63 by 20 feet 595 00:20:57,990 --> 00:20:56,480 each here they are inside the space 596 00:21:00,149 --> 00:20:58,000 station processing facility at the 597 00:21:02,149 --> 00:21:00,159 kennedy space center before being packed 598 00:21:03,990 --> 00:21:02,159 inside dragon the space station 599 00:21:06,549 --> 00:21:04,000 currently has eight pairs of solar 600 00:21:10,149 --> 00:21:06,559 arrays the oldest pair has been in use 601 00:21:11,990 --> 00:21:10,159 for more than 20 years the two new solar 602 00:21:14,830 --> 00:21:12,000 arrays plus four more to be delivered 603 00:21:18,149 --> 00:21:14,840 later will produce a total of more than 604 00:21:22,630 --> 00:21:18,159 120 kilowatts of electricity that is 605 00:21:24,789 --> 00:21:22,640 enough to power more than 40 u.s homes 606 00:21:27,190 --> 00:21:24,799 once combined with the eight original 607 00:21:30,470 --> 00:21:27,200 arrays the new ones will boost power to 608 00:21:32,470 --> 00:21:30,480 the station up to 30 percent maximizing 609 00:21:33,510 --> 00:21:32,480 use for the orbiting lab for many years 610 00:21:35,510 --> 00:21:33,520 to come 611 00:21:37,430 --> 00:21:35,520 and these new new solar arrays like 612 00:21:39,190 --> 00:21:37,440 courtney said are going to be installed 613 00:21:43,510 --> 00:21:39,200 this summer now let's head back over to 614 00:21:48,310 --> 00:21:46,070 thanks megan uh we're just over t minus 615 00:21:50,310 --> 00:21:48,320 seven minutes to go the spacex team 616 00:21:52,710 --> 00:21:50,320 currently working no significant issues 617 00:21:55,350 --> 00:21:52,720 with the vehicles at this point rocket 618 00:21:57,510 --> 00:21:55,360 propellant one fuel is nearly fully 619 00:22:00,310 --> 00:21:57,520 loaded on the first stage completely 620 00:22:02,070 --> 00:22:00,320 loaded on the second stage liquid oxygen 621 00:22:04,310 --> 00:22:02,080 loading is underway on both of the 622 00:22:06,470 --> 00:22:04,320 stages as well and that'll complete at 623 00:22:08,950 --> 00:22:06,480 about t minus two minutes to launch 624 00:22:11,510 --> 00:22:08,960 we're also loading helium gas into both 625 00:22:13,350 --> 00:22:11,520 of the stages falcon 9 uses helium as a 626 00:22:15,750 --> 00:22:13,360 pressure ant that's to backfill the 627 00:22:18,390 --> 00:22:15,760 propellant tanks as we consume liquid 628 00:22:20,789 --> 00:22:18,400 oxygen and rp1 by the merlin engines 629 00:22:22,710 --> 00:22:20,799 during ascent the helium loading began 630 00:22:24,549 --> 00:22:22,720 before the webcast went live and we'll 631 00:22:26,710 --> 00:22:24,559 continue to top it off until about a 632 00:22:28,789 --> 00:22:26,720 minute and a half before launch 633 00:22:31,029 --> 00:22:28,799 now to make sure that the engine startup 634 00:22:32,950 --> 00:22:31,039 goes well we also perform what's called 635 00:22:35,350 --> 00:22:32,960 engine chill it started at about t minus 636 00:22:37,350 --> 00:22:35,360 seven minutes we flow a small amount of 637 00:22:39,430 --> 00:22:37,360 that super chilled liquid oxygen into 638 00:22:41,110 --> 00:22:39,440 the merlin engine turbo pumps and we do 639 00:22:43,350 --> 00:22:41,120 that to avoid thermal shock to the 640 00:22:45,909 --> 00:22:43,360 mechanical components once we get that 641 00:22:48,549 --> 00:22:45,919 full flow of super chill liquid oxygen 642 00:22:50,710 --> 00:22:48,559 on engine start dragon also began its 643 00:22:52,070 --> 00:22:50,720 startup sequence at t minus 35 minutes 644 00:22:54,070 --> 00:22:52,080 when it coordinated timing with the 645 00:22:55,990 --> 00:22:54,080 falcon 9. it's currently undergoing a 646 00:22:58,070 --> 00:22:56,000 set of vehicle health checks with its 647 00:23:00,390 --> 00:22:58,080 next major milestone happening just 648 00:23:02,870 --> 00:23:00,400 before liftoff when it'll transition to 649 00:23:05,029 --> 00:23:02,880 internal battery power now the range is 650 00:23:07,510 --> 00:23:05,039 standing by ready to support today's 651 00:23:10,390 --> 00:23:07,520 mission launch weather is continuing to 652 00:23:12,230 --> 00:23:10,400 continuing to trend favorably we had a 653 00:23:13,669 --> 00:23:12,240 60 chance of go and we're still 654 00:23:16,630 --> 00:23:13,679 continuing to monitor some of those 655 00:23:19,190 --> 00:23:16,640 clouds and precipitation in the area 656 00:23:21,830 --> 00:23:19,200 so with that the launch team a falcon 9 657 00:23:25,270 --> 00:23:21,840 dragon the range all looking good 658 00:23:27,909 --> 00:23:25,280 weather also trending good and at about 659 00:23:30,310 --> 00:23:27,919 t minus five minutes to go i'm now 660 00:23:31,669 --> 00:23:30,320 joined by marie to help me walk through 661 00:23:33,750 --> 00:23:31,679 these final moments of the terminal 662 00:23:35,350 --> 00:23:33,760 count marie yeah shiva as you said 663 00:23:37,909 --> 00:23:35,360 whether i'm trending in the better 664 00:23:39,590 --> 00:23:37,919 direction it was a little bit 665 00:23:40,630 --> 00:23:39,600 a little bit hairy for a couple minutes 666 00:23:43,269 --> 00:23:40,640 there 667 00:23:45,190 --> 00:23:43,279 within the last oh i want to say maybe 668 00:23:46,070 --> 00:23:45,200 13 minutes or so it was right around t 669 00:23:48,310 --> 00:23:46,080 minus 670 00:23:50,390 --> 00:23:48,320 19 or 18 minutes we heard about some 671 00:23:52,789 --> 00:23:50,400 lightning strikes in the area not coming 672 00:23:55,190 --> 00:23:52,799 within that 10 mile radius of the pad 673 00:23:57,510 --> 00:23:55,200 but that was a watch item it looks like 674 00:23:59,590 --> 00:23:57,520 they're not expecting lightning to be an 675 00:24:01,269 --> 00:23:59,600 issue to come that close um and that 676 00:24:02,710 --> 00:24:01,279 cell that i mentioned to the south of 677 00:24:15,510 --> 00:24:02,720 the pad looks like dragon has 678 00:24:19,350 --> 00:24:17,110 okay so we heard that call that dragon 679 00:24:21,350 --> 00:24:19,360 is now on internal power 680 00:24:23,430 --> 00:24:21,360 again as shiva mentioned the team has 681 00:24:25,669 --> 00:24:23,440 already conducted its pre-launch engine 682 00:24:27,669 --> 00:24:25,679 chill again not this is when spacex 683 00:24:29,750 --> 00:24:27,679 injects a small amount of super chilled 684 00:24:32,230 --> 00:24:29,760 liquid oxygen to prepare those merlin 685 00:24:42,549 --> 00:24:32,240 engines inside the first stage to allow 686 00:24:46,710 --> 00:24:44,470 and we can hear the hissing from some of 687 00:24:49,510 --> 00:24:46,720 that liquid oxygen venting off the side 688 00:24:53,269 --> 00:24:49,520 of the rocket as it meets that um 689 00:24:57,990 --> 00:24:55,590 we just heard the call out there as well 690 00:25:00,870 --> 00:24:58,000 for strong back retract the strong back 691 00:25:03,430 --> 00:25:00,880 is the truss structure next to 692 00:25:05,350 --> 00:25:03,440 falcon 9 that provides propellants and 693 00:25:07,590 --> 00:25:05,360 power to the vehicle so you can see the 694 00:25:08,549 --> 00:25:07,600 clamp arms are opening around the second 695 00:25:10,230 --> 00:25:08,559 stage 696 00:25:12,630 --> 00:25:10,240 and the strong back will retract a 697 00:25:14,549 --> 00:25:12,640 couple of degrees away from the vertical 698 00:25:16,549 --> 00:25:14,559 position helping to clear the way for 699 00:25:18,630 --> 00:25:16,559 falcon 9's ascent in these last few 700 00:25:20,310 --> 00:25:18,640 minutes falcon 9 is performing a set of 701 00:25:22,710 --> 00:25:20,320 health checks on its primary 702 00:25:24,789 --> 00:25:22,720 communications avionics and propulsion 703 00:25:27,029 --> 00:25:24,799 systems in preparation for flight we'll 704 00:25:29,110 --> 00:25:27,039 continue to hear call outs the engines 705 00:25:30,630 --> 00:25:29,120 are sufficiently chilled in and for some 706 00:25:32,630 --> 00:25:30,640 of these milestones that are coming up 707 00:25:34,870 --> 00:25:32,640 next and there you can see 708 00:25:51,029 --> 00:25:34,880 the strong back starting its retraction 709 00:25:55,750 --> 00:25:53,190 and so we saw that strong back or 710 00:25:58,230 --> 00:25:55,760 transporter erector retract ever so 711 00:26:03,430 --> 00:25:58,240 slightly from the falcon 9 rocket it 712 00:26:08,230 --> 00:26:05,110 just as we get to the moment of liftoff 713 00:26:10,549 --> 00:26:08,240 to allow for falcon 9 to clear the pad 714 00:26:12,789 --> 00:26:10,559 also happening now are some checks of 715 00:26:15,750 --> 00:26:12,799 the second stage thrust vector control 716 00:26:17,750 --> 00:26:15,760 actuators uh that is often referred to 717 00:26:21,350 --> 00:26:17,760 as an engine wiggle test and this is 718 00:26:23,590 --> 00:26:21,360 when spacex moves the thrust nozzles 719 00:26:25,830 --> 00:26:23,600 we just heard the call for the stage one 720 00:26:27,510 --> 00:26:25,840 locks load complete again that engine 721 00:26:29,430 --> 00:26:27,520 wiggle test happening 722 00:26:31,830 --> 00:26:29,440 now to make sure that the guidance 723 00:26:33,909 --> 00:26:31,840 hardware is go for flight 724 00:26:35,990 --> 00:26:33,919 spacex will do the exact same checkouts 725 00:26:37,510 --> 00:26:36,000 on the first stage engines and that will 726 00:26:42,390 --> 00:26:37,520 happen just a few seconds before 727 00:26:46,470 --> 00:26:44,230 and we just heard that call out for 728 00:26:48,310 --> 00:26:46,480 first stage locks load complete 729 00:26:50,070 --> 00:26:48,320 next major activity here will be second 730 00:26:51,669 --> 00:26:50,080 stage locks load complete usually 731 00:26:53,750 --> 00:26:51,679 happens around the t minus two minute 732 00:27:01,590 --> 00:26:53,760 mark and that wraps up propellant 733 00:27:19,029 --> 00:27:03,990 dragon also continuing to perform final 734 00:27:23,909 --> 00:27:21,669 weather continuing to trend favorably as 735 00:27:46,149 --> 00:27:23,919 dragon transitions into 736 00:27:50,470 --> 00:27:48,630 and weather remaining uh go as we are 737 00:27:52,549 --> 00:27:50,480 approaching the t-minus one minute mark 738 00:27:59,190 --> 00:27:52,559 when dragon will transition to internal 739 00:28:12,149 --> 00:28:01,669 falcon 9's in startup 740 00:28:12,159 --> 00:28:15,750 ld go for launcher 741 00:28:15,760 --> 00:28:20,310 launch director pulled bail for lunch 742 00:28:25,430 --> 00:28:22,389 so that's not all systems are currently 743 00:28:28,870 --> 00:28:25,440 go we're just over t minus 30 seconds to 744 00:28:30,389 --> 00:28:28,880 lift off t minus 30 seconds 745 00:28:32,230 --> 00:28:30,399 and at t zero the rocket will be 746 00:28:34,389 --> 00:28:32,240 released from the hold down clamps at 747 00:28:36,470 --> 00:28:34,399 the pad and as i mentioned earlier that 748 00:28:38,470 --> 00:28:36,480 strong back right next to the to the 749 00:28:40,470 --> 00:28:38,480 rocket will retract the rest of the way 750 00:28:42,830 --> 00:28:40,480 clearing the way for lift off days you 751 00:28:45,190 --> 00:28:42,840 want pressure plate t minus 15 752 00:28:46,950 --> 00:28:45,200 seconds falcon 9 is configured for 753 00:28:47,750 --> 00:28:46,960 flight 754 00:28:48,710 --> 00:28:47,760 n 755 00:28:49,669 --> 00:28:48,720 9 756 00:28:50,710 --> 00:28:49,679 8 757 00:28:51,669 --> 00:28:50,720 7 758 00:28:52,630 --> 00:28:51,679 6 759 00:28:53,669 --> 00:28:52,640 5 760 00:28:54,630 --> 00:28:53,679 4 761 00:28:55,669 --> 00:28:54,640 3 762 00:28:56,549 --> 00:28:55,679 2 763 00:29:02,389 --> 00:28:56,559 1 764 00:29:07,909 --> 00:29:05,510 spacex cargo resupply mission bringing 765 00:29:12,710 --> 00:29:07,919 new solar arrays to the international 766 00:29:12,720 --> 00:29:40,310 stage more proportions 767 00:29:44,470 --> 00:29:42,870 we're at t plus 40 seconds into flight 768 00:29:47,110 --> 00:29:44,480 awesome shot looking 769 00:29:49,830 --> 00:29:47,120 pretty nominal uh the cape our falcon 9 770 00:29:51,990 --> 00:29:49,840 has launched we're coming up on the next 771 00:29:55,029 --> 00:29:52,000 major milestone that's the point of 772 00:29:56,310 --> 00:29:55,039 maximum aerodynamic pressure 773 00:29:57,990 --> 00:29:56,320 that's when the 774 00:30:03,190 --> 00:29:58,000 stresses on the vehicle will be the 775 00:30:03,200 --> 00:30:06,710 magnitude 776 00:30:10,389 --> 00:30:08,389 so in preparation for maximum 777 00:30:12,149 --> 00:30:10,399 aerodynamic pressure we throttle down 778 00:30:13,909 --> 00:30:12,159 those merlin 1d engines now that we're 779 00:30:16,070 --> 00:30:13,919 through that point we'll continue to 780 00:30:18,710 --> 00:30:16,080 we'll throttle back up and continue on 781 00:30:20,230 --> 00:30:18,720 to the next of our sequence of events we 782 00:30:22,470 --> 00:30:20,240 have several happening in rapid 783 00:30:24,789 --> 00:30:22,480 succession that'll be main engine cutoff 784 00:30:26,549 --> 00:30:24,799 followed by a stage separation then 785 00:30:29,110 --> 00:30:26,559 we'll have a first stage flip maneuver 786 00:30:31,430 --> 00:30:29,120 second engine start number one and then 787 00:30:33,750 --> 00:30:31,440 a boost back burn on the first stage now 788 00:30:36,470 --> 00:30:33,760 main engine cutoff or miko that's where 789 00:30:38,230 --> 00:30:36,480 all nine of the merlin 1d engines on the 790 00:30:40,070 --> 00:30:38,240 first stage will shut down that's 791 00:30:42,230 --> 00:30:40,080 followed shortly after by stage 792 00:30:44,470 --> 00:30:42,240 separation when both the first and the 793 00:30:46,470 --> 00:30:44,480 storms will separate 794 00:30:48,870 --> 00:30:46,480 from there the first stage will flip to 795 00:30:51,110 --> 00:30:48,880 prepare itself for entry a few seconds 796 00:30:53,029 --> 00:30:51,120 later the merlin vacuum engine on the 797 00:30:55,190 --> 00:30:53,039 second stage will ignite to boost the 798 00:30:57,509 --> 00:30:55,200 dragon into a low earth orbit that's 799 00:30:59,909 --> 00:30:57,519 called ses1 and then finally on the 800 00:31:02,310 --> 00:30:59,919 first stage boost back burns start to 801 00:31:03,590 --> 00:31:02,320 slow down the first stage in preparation 802 00:31:05,990 --> 00:31:03,600 for re-entry 803 00:31:08,389 --> 00:31:06,000 so again those five events miko stage 804 00:31:11,029 --> 00:31:08,399 separation first stage flip maneuver 805 00:31:14,630 --> 00:31:11,039 second engine start and then the boost 806 00:31:27,509 --> 00:31:14,640 back burn all coming up just in under 10 807 00:31:27,519 --> 00:31:30,389 and mikko 808 00:31:39,029 --> 00:31:33,220 stage separation confirmed 809 00:31:39,039 --> 00:31:42,630 in bag ignition 810 00:31:42,640 --> 00:31:48,870 stage one boost back startup 811 00:31:53,909 --> 00:31:51,430 so successful maryland vacuum engine 812 00:31:56,149 --> 00:31:53,919 startup first stage has begun its boost 813 00:31:59,190 --> 00:31:56,159 back burn that burn expected to last 814 00:32:02,549 --> 00:31:59,200 about 30 or so seconds here's a shot of 815 00:32:04,630 --> 00:32:02,559 the second stage maryland vacuum nozzle 816 00:32:06,310 --> 00:32:04,640 you can see it's starting to heat up 817 00:32:07,990 --> 00:32:06,320 as we begin this burn the second stage 818 00:32:09,750 --> 00:32:08,000 will continue to burn here for several 819 00:32:17,509 --> 00:32:09,760 minutes until about the t plus eight 820 00:32:17,519 --> 00:32:23,269 page one boost back shutdown 821 00:32:27,750 --> 00:32:25,430 if you're just joining us welcome you're 822 00:32:29,190 --> 00:32:27,760 watching a live webcast for the 22nd 823 00:32:31,190 --> 00:32:29,200 commercial resupply mission to the 824 00:32:34,070 --> 00:32:31,200 international space station for nasa 825 00:32:36,310 --> 00:32:34,080 this is spacex's 17th launch of the year 826 00:32:38,310 --> 00:32:36,320 and we are flying a cargo configuration 827 00:32:39,990 --> 00:32:38,320 of our new dragon spacecraft on the 828 00:32:42,389 --> 00:32:40,000 right hand side of your screen is the 829 00:32:45,269 --> 00:32:42,399 second stage which is carrying the 830 00:32:47,029 --> 00:32:45,279 dragon spacecraft into orbit 831 00:32:49,110 --> 00:32:47,039 on the left hand side of your screen you 832 00:32:51,509 --> 00:32:49,120 can see falcon 9's first stage with the 833 00:32:53,990 --> 00:32:51,519 grid fins extending 834 00:32:56,789 --> 00:32:54,000 it just completed its boost back burn 835 00:32:58,310 --> 00:32:56,799 and is making its way back to our drone 836 00:33:00,470 --> 00:32:58,320 ship 837 00:33:03,029 --> 00:33:00,480 now the rocket has to do more than just 838 00:33:04,870 --> 00:33:03,039 go up it has to go sideways really fast 839 00:33:07,029 --> 00:33:04,880 and lift off gravity is pulling straight 840 00:33:08,870 --> 00:33:07,039 down on the rocket but as we ascend we 841 00:33:10,549 --> 00:33:08,880 tilt the m the engines that's called 842 00:33:13,029 --> 00:33:10,559 gimbaling and that begins to turn the 843 00:33:15,509 --> 00:33:13,039 rocket horizontally we're still going up 844 00:33:17,029 --> 00:33:15,519 but we're also heading horizontally away 845 00:33:18,710 --> 00:33:17,039 from the launch pad that maneuver is 846 00:33:20,549 --> 00:33:18,720 called a gravity turn 847 00:33:24,310 --> 00:33:20,559 the rocket typically needs to go about 848 00:33:26,630 --> 00:33:24,320 7.5 kilometers per second or about 17 849 00:33:28,710 --> 00:33:26,640 500 miles an hour to avoid being pulled 850 00:33:30,389 --> 00:33:28,720 back down to earth and to get into orbit 851 00:33:32,149 --> 00:33:30,399 so that's what the second stage is doing 852 00:33:33,669 --> 00:33:32,159 right now 853 00:33:35,350 --> 00:33:33,679 now the first stage in order to make its 854 00:33:37,269 --> 00:33:35,360 way back to our drone ship named of 855 00:33:39,750 --> 00:33:37,279 course i still love you it has two more 856 00:33:41,990 --> 00:33:39,760 burns to do first is an entry burn it'll 857 00:33:43,509 --> 00:33:42,000 ignite three of its merlin one engines 858 00:33:45,669 --> 00:33:43,519 that'll help to slow it down as it 859 00:33:47,590 --> 00:33:45,679 re-enters the earth's atmosphere and 860 00:33:50,470 --> 00:33:47,600 then the next activity will happen much 861 00:33:52,630 --> 00:33:50,480 closer to the drone ship that is a the 862 00:33:54,870 --> 00:33:52,640 landing burn like night just the single 863 00:33:57,909 --> 00:33:54,880 center merlin engine to bring the 864 00:33:59,669 --> 00:33:57,919 vehicle speed rapidly down to zero 865 00:34:01,190 --> 00:33:59,679 you can see the grid fins that are 866 00:34:03,590 --> 00:34:01,200 extended on the left hand side of your 867 00:34:06,549 --> 00:34:03,600 screen we use those for atmospheric 868 00:34:07,990 --> 00:34:06,559 control they help steer the falcon 9 to 869 00:34:09,349 --> 00:34:08,000 make sure we make our way back to that 870 00:34:10,710 --> 00:34:09,359 drone ship 871 00:34:12,710 --> 00:34:10,720 as we get into the thicker parts of the 872 00:34:14,869 --> 00:34:12,720 earth's atmosphere 873 00:34:17,270 --> 00:34:14,879 and you'll occasionally see periodic 874 00:34:19,510 --> 00:34:17,280 bursts of a white gas 875 00:34:20,389 --> 00:34:19,520 like that that's our attitude control 876 00:34:22,389 --> 00:34:20,399 system 877 00:34:24,470 --> 00:34:22,399 giving us little corrections to our 878 00:34:26,550 --> 00:34:24,480 attitude the next major event coming up 879 00:34:28,230 --> 00:34:26,560 here for the first stage is entry burn 880 00:34:30,629 --> 00:34:28,240 three of the merlin 1d engines will 881 00:34:33,109 --> 00:34:30,639 ignite second stage burn continuing to 882 00:34:34,629 --> 00:34:33,119 look nominal second stage has a little 883 00:34:36,550 --> 00:34:34,639 ways to go it won't be done with this 884 00:34:48,950 --> 00:34:36,560 burn until about the t plus eight minute 885 00:34:48,960 --> 00:34:52,629 stage one fts is saved 886 00:34:52,639 --> 00:34:56,790 trajectory nominal 887 00:34:56,800 --> 00:35:00,829 stage one entry burn 888 00:35:06,069 --> 00:35:04,069 startup with that three marilyn 1d 889 00:35:08,230 --> 00:35:06,079 engines on the first stage igniting to 890 00:35:10,150 --> 00:35:08,240 reduce the vehicle's velocity you can 891 00:35:13,990 --> 00:35:10,160 see that on the bottom left corner of 892 00:35:14,000 --> 00:35:19,190 just burn expectations 893 00:35:22,630 --> 00:35:21,109 so from here the grid fins will continue 894 00:35:24,790 --> 00:35:22,640 to take the first stage towards our 895 00:35:26,310 --> 00:35:24,800 drone ship stationed out in the atlantic 896 00:35:27,829 --> 00:35:26,320 ocean 897 00:35:29,670 --> 00:35:27,839 at this point t plus six and a half 898 00:35:31,990 --> 00:35:29,680 minutes into flight second stage is 899 00:35:35,829 --> 00:35:32,000 making its way to the initial orbit to 900 00:35:37,750 --> 00:35:35,839 drop off the cargo dragon spacecraft 901 00:35:38,710 --> 00:35:37,760 and uh if you're just joining us 902 00:35:40,230 --> 00:35:38,720 welcome 903 00:35:42,390 --> 00:35:40,240 on your screen is a live view of falcon 904 00:35:44,870 --> 00:35:42,400 9's first stage on the left the second 905 00:35:48,230 --> 00:35:44,880 stage on the right we had a an on time 906 00:35:53,829 --> 00:35:48,240 liftoff at 1 29 p.m eastern time nominal 907 00:35:58,710 --> 00:35:55,750 talking a little bit more about the one 908 00:35:59,990 --> 00:35:58,720 transonic 909 00:36:01,910 --> 00:36:00,000 talking a little bit more about the 910 00:36:04,069 --> 00:36:01,920 first stage so the next major event 911 00:36:05,589 --> 00:36:04,079 coming up is that landing burn landing 912 00:36:14,390 --> 00:36:05,599 burn is what will bring the vehicle 913 00:36:19,910 --> 00:36:16,550 amazing shots of the first stage during 914 00:36:24,870 --> 00:36:22,230 once we get closer to the drone ship we 915 00:36:26,710 --> 00:36:24,880 will deploy our four symmetric landing 916 00:36:28,790 --> 00:36:26,720 legs around the base of the first stage 917 00:36:30,710 --> 00:36:28,800 for hopefully a nice soft touchdown on 918 00:36:31,589 --> 00:36:30,720 that drone ship you can see a shot of 919 00:36:38,390 --> 00:36:31,599 that on the right hand side of your 920 00:36:38,400 --> 00:36:48,390 stage one landing leg deploy 921 00:36:52,950 --> 00:36:50,390 picture-perfect landing 922 00:36:54,470 --> 00:36:52,960 of that falcon 930 run 923 00:36:56,870 --> 00:36:54,480 first landing 924 00:37:00,069 --> 00:36:56,880 for this first stage 86 successful 925 00:37:01,670 --> 00:37:00,079 recovery overall for spacex 926 00:37:03,510 --> 00:37:01,680 fantastic 927 00:37:05,109 --> 00:37:03,520 coming up shortly second stage is not 928 00:37:07,270 --> 00:37:05,119 done 929 00:37:09,510 --> 00:37:07,280 it will be coming up on a second engine 930 00:37:12,230 --> 00:37:09,520 cut off 931 00:37:13,589 --> 00:37:12,240 about 30. excuse me under 30 seconds 932 00:37:15,190 --> 00:37:13,599 from now 933 00:37:17,670 --> 00:37:15,200 it's been burning that whole time since 934 00:37:21,670 --> 00:37:17,680 stage separation to bring the 7 000 935 00:37:23,270 --> 00:37:21,680 pounds of cargo into the initial orbit 936 00:37:24,550 --> 00:37:23,280 around our planet 937 00:37:48,310 --> 00:37:24,560 you can see we're 938 00:37:52,230 --> 00:37:50,390 shut down of the second stage engine 939 00:37:56,950 --> 00:37:52,240 from here we'll be looking at telemetry 940 00:37:56,960 --> 00:38:01,190 nominal orbit insertion 941 00:38:05,270 --> 00:38:02,630 fantastic 942 00:38:07,109 --> 00:38:05,280 so is not the second stage has just one 943 00:38:09,430 --> 00:38:07,119 major task left 944 00:38:13,109 --> 00:38:09,440 this commanding separation of the dragon 945 00:38:15,190 --> 00:38:13,119 spacecraft just a few minutes from now 946 00:38:17,510 --> 00:38:15,200 until separation the second stage will 947 00:38:19,670 --> 00:38:17,520 be making some small adjustments 948 00:38:22,390 --> 00:38:19,680 during this coast prior to dragon 949 00:38:24,150 --> 00:38:22,400 separation and we're hoping 950 00:38:27,349 --> 00:38:24,160 we're hoping to have a video there's 951 00:38:29,990 --> 00:38:27,359 some video into the unpressurized cargo 952 00:38:32,069 --> 00:38:30,000 section of dragon this video from the 953 00:38:34,470 --> 00:38:32,079 top of the second stage we got a good 954 00:38:36,630 --> 00:38:34,480 look there at the new 955 00:38:38,069 --> 00:38:36,640 rollout solar arrays that cargo dragon 956 00:38:41,750 --> 00:38:38,079 is bringing to the international space 957 00:38:48,710 --> 00:38:43,990 so separation of the dragon spacecraft 958 00:38:52,630 --> 00:38:50,790 we have a little bit of a coast here for 959 00:38:55,190 --> 00:38:52,640 ground operators in mission control 960 00:38:56,790 --> 00:38:55,200 behind me to ensure that the vehicle is 961 00:38:58,550 --> 00:38:56,800 in the right configuration that there's 962 00:39:00,150 --> 00:38:58,560 no 963 00:39:02,710 --> 00:39:00,160 conditions that we may want to watch out 964 00:39:04,790 --> 00:39:02,720 for after separation 965 00:39:07,910 --> 00:39:04,800 that dragon and the stage 2 right now in 966 00:39:12,630 --> 00:39:11,190 and coming up after that separation 967 00:39:15,670 --> 00:39:12,640 event which hopefully we'll get a view 968 00:39:16,390 --> 00:39:15,680 like this of dragon gently floating away 969 00:39:18,390 --> 00:39:16,400 the 970 00:39:20,630 --> 00:39:18,400 dragon spacecraft will begin to perform 971 00:39:23,510 --> 00:39:20,640 some of its own checkouts dragon is 972 00:39:25,670 --> 00:39:23,520 equipped with 12 service section draco 973 00:39:27,670 --> 00:39:25,680 thrusters that are used primarily for 974 00:39:30,630 --> 00:39:27,680 attitude control and proximity next to 975 00:39:32,470 --> 00:39:30,640 the space station it's also got four 976 00:39:34,630 --> 00:39:32,480 draco thrusters on the top of the 977 00:39:35,990 --> 00:39:34,640 vehicle underneath its nose cone that we 978 00:39:37,190 --> 00:39:36,000 use for 979 00:39:39,990 --> 00:39:37,200 our 980 00:39:47,910 --> 00:39:40,000 thrust maneuvers to help us rendezvous 981 00:39:53,109 --> 00:39:50,390 so again successful ascent successful 982 00:39:54,310 --> 00:39:53,119 recovery of our first stage just a few 983 00:39:57,190 --> 00:39:54,320 minutes ago 984 00:39:58,790 --> 00:39:57,200 you're looking at a live shot into the 985 00:40:01,349 --> 00:39:58,800 cargo dragon 986 00:40:02,870 --> 00:40:01,359 uh unpressurized section from the second 987 00:40:05,109 --> 00:40:02,880 stage that is 988 00:40:06,950 --> 00:40:05,119 in orbit around our planet 989 00:40:10,309 --> 00:40:06,960 our next major activity coming up 990 00:40:26,230 --> 00:40:10,319 shortly that is dragon separation from 991 00:40:30,150 --> 00:40:27,990 something a little bit different about 992 00:40:32,150 --> 00:40:30,160 uh this dragon spacecraft 993 00:40:34,309 --> 00:40:32,160 if you followed our first version of 994 00:40:36,710 --> 00:40:34,319 dragon you'd know that uh it had 995 00:40:40,150 --> 00:40:36,720 deployable solar arrays this version of 996 00:40:43,190 --> 00:40:40,160 dragon has conformal solar arrays on the 997 00:40:45,510 --> 00:40:43,200 body of the spacecraft 998 00:40:47,270 --> 00:40:45,520 so those are mounted along the exterior 999 00:40:48,710 --> 00:40:47,280 panel of the trunk that we're looking 1000 00:40:50,950 --> 00:40:48,720 into right now 1001 00:40:54,630 --> 00:40:50,960 those provide power for the spacecraft 1002 00:41:02,390 --> 00:40:54,640 as it makes its way to the space station 1003 00:41:06,309 --> 00:41:03,990 lovely planet earth on the left hand 1004 00:41:07,750 --> 00:41:06,319 side dragon floating away you can see 1005 00:41:11,190 --> 00:41:07,760 the 1006 00:41:14,550 --> 00:41:12,390 from this view 1007 00:41:17,030 --> 00:41:14,560 atop falcon 9's second stage watching 1008 00:41:19,270 --> 00:41:17,040 dragon gently float away 1009 00:41:21,430 --> 00:41:19,280 so again activities coming up for dragon 1010 00:41:22,790 --> 00:41:21,440 it will begin its service section draco 1011 00:41:26,150 --> 00:41:22,800 checkouts 1012 00:41:27,510 --> 00:41:26,160 followed shortly after that by 1013 00:41:31,190 --> 00:41:27,520 the nosecone 1014 00:41:33,829 --> 00:41:31,200 expected loss of signal opening 1015 00:41:35,829 --> 00:41:33,839 and that's going to complete my coverage 1016 00:41:37,670 --> 00:41:35,839 here from hawthorne but why don't we 1017 00:41:44,630 --> 00:41:37,680 check in with courtney at the johnson 1018 00:41:56,790 --> 00:41:46,550 thanks shiva again just standing by for 1019 00:42:01,109 --> 00:41:59,349 the nosecone deploy uncovers the four 1020 00:42:02,870 --> 00:42:01,119 forward bulkhead thrusters which dragon 1021 00:42:42,710 --> 00:42:02,880 will use for its major burn maneuvers 1022 00:42:42,720 --> 00:43:02,309 and nosecone hooks are driving now 1023 00:43:05,990 --> 00:43:03,910 and the hooks are halfway open again 1024 00:44:00,710 --> 00:43:06,000 standing by 1025 00:44:02,230 --> 00:44:00,720 that nose cone will stay open in the 1026 00:44:17,109 --> 00:44:02,240 position until the very end of the 1027 00:44:21,109 --> 00:44:19,030 and the first set of nose cone hooks are 1028 00:44:52,230 --> 00:44:21,119 open and the second set are starting to 1029 00:44:55,829 --> 00:44:54,230 again once the nose cone is open it will 1030 00:44:57,990 --> 00:44:55,839 stay in that position until the very end 1031 00:45:00,390 --> 00:44:58,000 of its mission closing prior to re-entry 1032 00:45:11,910 --> 00:45:00,400 to provide some additional protection to 1033 00:45:11,920 --> 00:45:53,430 expected lots of signal newfoundland 1034 00:45:58,069 --> 00:45:55,190 again standing by for confirmation of 1035 00:46:00,230 --> 00:45:58,079 nose cone deploy and this nose cone 1036 00:46:01,910 --> 00:46:00,240 deploy will uncover those four bulkhead 1037 00:46:04,069 --> 00:46:01,920 thrusters and that's what dragon will 1038 00:46:05,670 --> 00:46:04,079 use for its major burns 1039 00:46:07,190 --> 00:46:05,680 coming up throughout the next day to 1040 00:46:09,510 --> 00:46:07,200 catch up with the space station before 1041 00:46:32,069 --> 00:46:09,520 docking 1042 00:46:32,079 --> 00:46:38,150 and the nose cone is opening 1043 00:46:38,160 --> 00:46:50,550 and nose cone deploy confirmed 1044 00:46:55,109 --> 00:46:52,790 and with nosecone deploy now confirmed 1045 00:46:56,790 --> 00:46:55,119 now joining me on the phone is manager 1046 00:46:58,710 --> 00:46:56,800 of the international space station 1047 00:47:01,430 --> 00:46:58,720 office for systems engineering and 1048 00:47:03,829 --> 00:47:01,440 integration jeff aaron jeff one major 1049 00:47:05,910 --> 00:47:03,839 component in dragon's trunk today is the 1050 00:47:08,230 --> 00:47:05,920 first set of irosa solar arrays can you 1051 00:47:09,910 --> 00:47:08,240 tell us the importance of augmenting the 1052 00:47:13,030 --> 00:47:09,920 station's power supply through these 1053 00:47:15,510 --> 00:47:13,040 irosa spacewalks later this month 1054 00:47:16,550 --> 00:47:15,520 absolutely courtney uh how do you hear 1055 00:47:19,190 --> 00:47:16,560 me 1056 00:47:21,829 --> 00:47:19,200 perfect i hear you great okay very good 1057 00:47:23,190 --> 00:47:21,839 um yeah that's a great question um so 1058 00:47:24,870 --> 00:47:23,200 i'm gonna kind of start at the beginning 1059 00:47:27,829 --> 00:47:24,880 a little bit because the punchline at 1060 00:47:29,910 --> 00:47:27,839 the end is probably the best but 1061 00:47:32,549 --> 00:47:29,920 you know over time our our solar rays 1062 00:47:35,510 --> 00:47:32,559 age and uh so the first set of rays have 1063 00:47:38,150 --> 00:47:35,520 uh have been up there over 20 years 1064 00:47:39,829 --> 00:47:38,160 our most recent arrays we brought up you 1065 00:47:41,990 --> 00:47:39,839 know just before shuttle retirement 1066 00:47:43,109 --> 00:47:42,000 those arrays are over 10 years old as 1067 00:47:45,270 --> 00:47:43,119 well and then 1068 00:47:47,829 --> 00:47:45,280 the set in between are 1069 00:47:49,430 --> 00:47:47,839 are closer to 15 years old 1070 00:47:50,710 --> 00:47:49,440 so over time 1071 00:47:53,349 --> 00:47:50,720 the arrays aren't as efficient at 1072 00:47:55,030 --> 00:47:53,359 generating power so that's that's one of 1073 00:47:56,950 --> 00:47:55,040 the things we wanted to fix with the 1074 00:47:58,309 --> 00:47:56,960 with the augmentation 1075 00:48:01,109 --> 00:47:58,319 um 1076 00:48:03,430 --> 00:48:01,119 so when we actually the first two we do 1077 00:48:05,589 --> 00:48:03,440 are the oldest arrays which makes sense 1078 00:48:07,349 --> 00:48:05,599 we took first two that we replaced and 1079 00:48:09,270 --> 00:48:07,359 that will effectively restore those 1080 00:48:11,430 --> 00:48:09,280 arrays back to what we would call their 1081 00:48:14,230 --> 00:48:11,440 beginning of life properties 1082 00:48:15,829 --> 00:48:14,240 um and in the case of the newer arrays 1083 00:48:17,670 --> 00:48:15,839 you know the ones that are 10 to 15 1084 00:48:20,390 --> 00:48:17,680 years old that are that will eventually 1085 00:48:22,309 --> 00:48:20,400 get the the iro says they'll actually be 1086 00:48:24,710 --> 00:48:22,319 able to generate more power than they 1087 00:48:26,630 --> 00:48:24,720 than they can today 1088 00:48:28,470 --> 00:48:26,640 so this product this provides basically 1089 00:48:31,990 --> 00:48:28,480 three significant benefits i kind of 1090 00:48:34,470 --> 00:48:32,000 alluded to the to one of the two which 1091 00:48:38,309 --> 00:48:34,480 but let me let me kind of go through an 1092 00:48:40,309 --> 00:48:38,319 order here for in in my logical mind 1093 00:48:42,150 --> 00:48:40,319 so for one for our solar array 1094 00:48:44,230 --> 00:48:42,160 constraint events it makes it easier for 1095 00:48:46,470 --> 00:48:44,240 us to manage the solar rays 1096 00:48:47,750 --> 00:48:46,480 uh an example of that would be about 1097 00:48:50,309 --> 00:48:47,760 what we're going to see tomorrow so 1098 00:48:51,990 --> 00:48:50,319 visiting vehicle dockings and undockings 1099 00:48:53,670 --> 00:48:52,000 you know the arrays can't always point 1100 00:48:55,589 --> 00:48:53,680 at the sun we have to protect them from 1101 00:48:59,270 --> 00:48:55,599 plumes from the vehicles 1102 00:49:03,510 --> 00:49:00,790 some of the loads that we see on the 1103 00:49:05,589 --> 00:49:03,520 arrays so we call those in that's a 1104 00:49:07,670 --> 00:49:05,599 a visiting vehicle or solar array 1105 00:49:09,750 --> 00:49:07,680 constrained event 1106 00:49:11,670 --> 00:49:09,760 it also helps us this this augmentation 1107 00:49:13,990 --> 00:49:11,680 is going to help us to fully 1108 00:49:17,030 --> 00:49:14,000 uh to extend the life of iss and fully 1109 00:49:18,470 --> 00:49:17,040 execute our full suite of research as we 1110 00:49:20,790 --> 00:49:18,480 as we move forward 1111 00:49:22,710 --> 00:49:20,800 and probably most importantly it allows 1112 00:49:25,270 --> 00:49:22,720 allows us to power more science and 1113 00:49:27,589 --> 00:49:25,280 research especially in the form of 1114 00:49:29,589 --> 00:49:27,599 future exploration systems and 1115 00:49:31,670 --> 00:49:29,599 commercial users the one that i'm 1116 00:49:33,589 --> 00:49:31,680 thinking about in particular particular 1117 00:49:36,150 --> 00:49:33,599 would be the axiom module that we hope 1118 00:49:38,390 --> 00:49:36,160 to see later on 1119 00:49:41,750 --> 00:49:38,400 in a few years from now on on the front 1120 00:49:45,510 --> 00:49:43,430 and of course these resupply missions 1121 00:49:47,430 --> 00:49:45,520 deliver science hardware and other cargo 1122 00:49:49,109 --> 00:49:47,440 like you were just saying to the station 1123 00:49:51,990 --> 00:49:49,119 how critical are these deliveries for 1124 00:49:54,710 --> 00:49:52,000 the station and astronauts 1125 00:49:56,390 --> 00:49:54,720 so over any six-month planning period 1126 00:49:58,549 --> 00:49:56,400 there are hundreds of experiments being 1127 00:50:00,870 --> 00:49:58,559 conducted on board 1128 00:50:02,549 --> 00:50:00,880 the vehicle that delivers our crews you 1129 00:50:03,990 --> 00:50:02,559 know they are the vehicles that deliver 1130 00:50:06,309 --> 00:50:04,000 our crews you know they do a great job 1131 00:50:09,030 --> 00:50:06,319 of getting the crews there safely 1132 00:50:10,870 --> 00:50:09,040 um to and from station but their cargo 1133 00:50:13,750 --> 00:50:10,880 capacity is very limited on the order of 1134 00:50:15,670 --> 00:50:13,760 100 maybe 200 kilos 1135 00:50:17,589 --> 00:50:15,680 we couldn't conduct all the science we 1136 00:50:19,190 --> 00:50:17,599 do as well as provide for our crew 1137 00:50:21,589 --> 00:50:19,200 members without 1138 00:50:23,829 --> 00:50:21,599 without our cargo resupply vehicles 1139 00:50:25,270 --> 00:50:23,839 which can carry about in this particular 1140 00:50:28,390 --> 00:50:25,280 case about two metric tons of 1141 00:50:29,750 --> 00:50:28,400 pressurized cargo in research 1142 00:50:32,230 --> 00:50:29,760 our cargo flights are vital to 1143 00:50:33,910 --> 00:50:32,240 maintaining and fully utilizing our 1144 00:50:35,990 --> 00:50:33,920 orbiting laboratory 1145 00:50:38,710 --> 00:50:36,000 in the case of this spacex 22 we're 1146 00:50:40,710 --> 00:50:38,720 bringing up about 900 kilos of research 1147 00:50:41,670 --> 00:50:40,720 supplies to support our ongoing science 1148 00:50:45,510 --> 00:50:41,680 program 1149 00:50:47,990 --> 00:50:45,520 and it will also return about 1200 kilos 1150 00:50:51,349 --> 00:50:48,000 of science samples and supplies for 1151 00:50:53,910 --> 00:50:51,359 human research biology biotechnology 1152 00:50:55,990 --> 00:50:53,920 physical science investigation education 1153 00:50:58,150 --> 00:50:56,000 studies 1154 00:51:00,549 --> 00:50:58,160 the return piece of this the science and 1155 00:51:03,270 --> 00:51:00,559 research return it can't be emphasized 1156 00:51:05,430 --> 00:51:03,280 enough because a unique service that the 1157 00:51:07,349 --> 00:51:05,440 spacex cargo vehicle provides is 1158 00:51:09,190 --> 00:51:07,359 returned cargo 1159 00:51:11,270 --> 00:51:09,200 otherwise the only way we can get car 1160 00:51:13,190 --> 00:51:11,280 return cargo down in samples is on our 1161 00:51:15,990 --> 00:51:13,200 crewed vehicle so 1162 00:51:17,430 --> 00:51:16,000 which again is fairly limited 1163 00:51:19,910 --> 00:51:17,440 these vehicles also bring critical 1164 00:51:21,030 --> 00:51:19,920 spares to help us maintain our onboard 1165 00:51:23,750 --> 00:51:21,040 systems 1166 00:51:25,670 --> 00:51:23,760 keep the space seats maintained and of 1167 00:51:28,069 --> 00:51:25,680 course provide food food and crew 1168 00:51:30,790 --> 00:51:28,079 support items so super critical to what 1169 00:51:33,030 --> 00:51:30,800 we do each and every day 1170 00:51:34,390 --> 00:51:33,040 and as always it's a busy time aboard 1171 00:51:36,390 --> 00:51:34,400 the international space station with 1172 00:51:38,870 --> 00:51:36,400 cargo vehicles and crews coming and 1173 00:51:41,270 --> 00:51:38,880 going one russian spacewalk behind us 1174 00:51:42,790 --> 00:51:41,280 and two u.s spacewalks later this month 1175 00:51:44,470 --> 00:51:42,800 can you kind of lay out how complex the 1176 00:51:47,829 --> 00:51:44,480 next few months will be for the station 1177 00:51:49,589 --> 00:51:47,839 program and the global partnership 1178 00:51:52,870 --> 00:51:49,599 complex well i hope i don't have to call 1179 00:51:54,390 --> 00:51:52,880 it complex maybe exciting fast-paced fun 1180 00:51:57,349 --> 00:51:54,400 times um 1181 00:51:59,109 --> 00:51:57,359 you know we plan everything to a t and 1182 00:52:01,190 --> 00:51:59,119 analyze it do those kind of things so we 1183 00:52:02,630 --> 00:52:01,200 like to try to limit eliminate the 1184 00:52:04,790 --> 00:52:02,640 complexity is the way i would kind of 1185 00:52:06,870 --> 00:52:04,800 describe it but you're right it's a very 1186 00:52:08,630 --> 00:52:06,880 busy time and so 1187 00:52:11,270 --> 00:52:08,640 from a visiting vehicle point of view i 1188 00:52:14,309 --> 00:52:11,280 think the up upcoming amount of traffic 1189 00:52:15,349 --> 00:52:14,319 is about as busy as we've ever had 1190 00:52:17,190 --> 00:52:15,359 there are also going to be some 1191 00:52:18,790 --> 00:52:17,200 configuration changes mostly on the 1192 00:52:21,190 --> 00:52:18,800 russian segment that will keep our 1193 00:52:23,910 --> 00:52:21,200 flight control engineering and partners 1194 00:52:25,430 --> 00:52:23,920 very busy over the next few months 1195 00:52:27,349 --> 00:52:25,440 as you pointed out we just with the 1196 00:52:29,190 --> 00:52:27,359 completion of the russian segment eva 1197 00:52:30,309 --> 00:52:29,200 which was actually yesterday it seems 1198 00:52:32,549 --> 00:52:30,319 like 1199 00:52:34,790 --> 00:52:32,559 days or weeks ago as fast as fast as 1200 00:52:36,549 --> 00:52:34,800 everything is going here lately but the 1201 00:52:38,150 --> 00:52:36,559 russian segment is now going to be ready 1202 00:52:40,150 --> 00:52:38,160 for the undock of the docking 1203 00:52:42,309 --> 00:52:40,160 compartment which is another module 1204 00:52:43,430 --> 00:52:42,319 that's been on board for about 20 years 1205 00:52:45,829 --> 00:52:43,440 or so 1206 00:52:48,230 --> 00:52:45,839 and this opens the port up for the the 1207 00:52:49,910 --> 00:52:48,240 next basically the third large module 1208 00:52:52,390 --> 00:52:49,920 that our that our russian partners will 1209 00:52:55,190 --> 00:52:52,400 be bringing to iss it's the mlm or 1210 00:52:57,589 --> 00:52:55,200 multi-purpose logistics module and that 1211 00:52:59,510 --> 00:52:57,599 docking is later in july 1212 00:53:02,069 --> 00:52:59,520 you know but before that shortly after 1213 00:53:04,309 --> 00:53:02,079 spacex stocks we'll be conducting 1214 00:53:06,230 --> 00:53:04,319 two evas ourselves one on the 16th and 1215 00:53:09,349 --> 00:53:06,240 then the other as things go well in the 1216 00:53:12,549 --> 00:53:09,359 20th of june to install the irosa the 1217 00:53:14,790 --> 00:53:12,559 irosa arrays 1218 00:53:17,510 --> 00:53:14,800 maybe this is where we where complex 1219 00:53:19,910 --> 00:53:17,520 comes into play um all evas are 1220 00:53:21,910 --> 00:53:19,920 challenging but these irosa arrays in 1221 00:53:23,750 --> 00:53:21,920 particular are probably probably more so 1222 00:53:26,150 --> 00:53:23,760 than some of our other ones 1223 00:53:27,750 --> 00:53:26,160 and then finally shortly after the mlm 1224 00:53:30,230 --> 00:53:27,760 arrives 1225 00:53:32,390 -->
