Tennessee vol fan 52 00:03:37,879 --> 00:03:36,540 whoo go Vols so yeah hey Tim we're here 53 00:03:39,319 --> 00:03:37,889 to talk about rockets today and you know 54 00:03:41,960 --> 00:03:39,329 that's the important thing for our folks 55 00:03:43,339 --> 00:03:41,970 listening at home today and one of the 56 00:03:45,379 --> 00:03:43,349 things we really need to get out of the 57 00:03:47,659 --> 00:03:45,389 way is first why do Rockets work right I 58 00:03:50,210 --> 00:03:47,669 mean Isaac Newton created these laws and 59 00:03:54,170 --> 00:03:50,220 that's really the basis of what Rockets 60 00:03:58,580 --> 00:03:54,180 work yeah let's look at that so as 61 00:04:02,599 --> 00:03:58,590 legend has it roughly 350 years ago ol 62 00:04:05,059 --> 00:04:02,609 Sir Isaac was out in the orchard and he 63 00:04:08,330 --> 00:04:05,069 saw the Apple fall from the tree and 64 00:04:12,289 --> 00:04:08,340 thus started the wheels of motion so in 65 00:04:14,719 --> 00:04:12,299 his brain so that first law is is a 66 00:04:17,120 --> 00:04:14,729 universal law of gravitation and it 67 00:04:19,310 --> 00:04:17,130 basically defines how we're all 68 00:04:21,949 --> 00:04:19,320 connected to each other and most 69 00:04:24,950 --> 00:04:21,959 importantly how rockets and spacecraft 70 00:04:26,450 --> 00:04:24,960 are connected to planet Earth until we 71 00:04:30,110 --> 00:04:26,460 do something to get them off the earth 72 00:04:32,960 --> 00:04:30,120 it also defines that even though me and 73 00:04:35,779 --> 00:04:32,970 my good buddy Mick Wolfman are about 10 74 00:04:38,330 --> 00:04:35,789 miles apart right now absolutely still 75 00:04:41,180 --> 00:04:38,340 absolutely attracted to each other right 76 00:04:43,010 --> 00:04:41,190 Mick absolutely Tim Alabama fan ball fan 77 00:04:44,149 --> 00:04:43,020 attract each other we get it to get us 78 00:04:45,680 --> 00:04:44,159 great but you know what's really 79 00:04:47,719 --> 00:04:45,690 important about rockets and why they 80 00:04:48,519 --> 00:04:47,729 work is Newton's third law and as you 81 00:04:49,779 --> 00:04:48,529 can see in 82 00:04:52,509 --> 00:04:49,789 chart that we showed a little earlier 83 00:04:54,729 --> 00:04:52,519 moons third law is to every action 84 00:04:57,129 --> 00:04:54,739 there's an equal and opposite reaction 85 00:04:59,799 --> 00:04:57,139 and that is the basis for what rockets 86 00:05:01,509 --> 00:04:59,809 do for us right we have a reaction we 87 00:05:03,369 --> 00:05:01,519 get an equal and opposite reaction to 88 00:05:06,399 --> 00:05:03,379 get off Earth and get things traveling 89 00:05:09,279 --> 00:05:06,409 so it's right yeah so why rockets right 90 00:05:11,589 --> 00:05:09,289 we've asked that right well we as humans 91 00:05:13,899 --> 00:05:11,599 work naturally curiosity to study things 92 00:05:16,779 --> 00:05:13,909 that we can see we want to get off the 93 00:05:18,099 --> 00:05:16,789 planet right we want to launch people we 94 00:05:20,079 --> 00:05:18,109 want to launch probes we won't launch 95 00:05:21,729 --> 00:05:20,089 satellites well as Tim said we need 96 00:05:24,429 --> 00:05:21,739 velocity that we need to be traveling 97 00:05:25,689 --> 00:05:24,439 about 17,000 800 miles an hour now that 98 00:05:27,849 --> 00:05:25,699 all about you folks out there at home 99 00:05:34,329 --> 00:05:27,859 but Tim and I don't drive that fast 100 00:05:37,269 --> 00:05:34,339 going to work every day fifty miles per 101 00:05:38,829 --> 00:05:37,279 hour on KSC property exactly we do not 102 00:05:40,809 --> 00:05:38,839 exceed the seventeen thousand eight 103 00:05:43,149 --> 00:05:40,819 hundred mile an hour limit on KSC at all 104 00:05:44,469 --> 00:05:43,159 but we need to visit and study and 105 00:05:46,059 --> 00:05:44,479 observe our universe that's another 106 00:05:48,249 --> 00:05:46,069 reason we have Rockets right to get our 107 00:05:50,289 --> 00:05:48,259 spacecraft traveling fast enough to 108 00:05:53,019 --> 00:05:50,299 reach the edge of the universe and to do 109 00:05:55,269 --> 00:05:53,029 that our Rockets help our spacecraft get 110 00:05:57,759 --> 00:05:55,279 traveling up to about 46,000 miles hour 111 00:05:59,889 --> 00:05:57,769 or beyond and you know we're looking to 112 00:06:01,989 --> 00:05:59,899 him to actually start launching humans 113 00:06:03,909 --> 00:06:01,999 again from Kennedy Space Center I think 114 00:06:05,709 --> 00:06:03,919 that's really cool and we that's one of 115 00:06:08,229 --> 00:06:05,719 the things we'll use rockets for so you 116 00:06:09,759 --> 00:06:08,239 know ironically rockets they're just 117 00:06:12,189 --> 00:06:09,769 plain cool to them that's all it is 118 00:06:15,100 --> 00:06:12,199 rockets are just plain cool but you know 119 00:06:17,589 --> 00:06:15,110 what absolutely love rockets our whole 120 00:06:20,439 --> 00:06:17,599 lives have been about rockets we've done 121 00:06:23,409 --> 00:06:20,449 everything in our power since we were 122 00:06:26,379 --> 00:06:23,419 small little children to make sure that 123 00:06:29,589 --> 00:06:26,389 we could have a part in the space 124 00:06:31,989 --> 00:06:29,599 industry of the United States and we are 125 00:06:34,539 --> 00:06:31,999 so blessed and thrilled to be working 126 00:06:36,789 --> 00:06:34,549 for NASA and to be sharing some rocket 127 00:06:38,109 --> 00:06:36,799 love with you guys today yeah Tim 128 00:06:39,789 --> 00:06:38,119 actually we you and I've talked about 129 00:06:41,559 --> 00:06:39,799 that before we've had some great things 130 00:06:43,209 --> 00:06:41,569 as we've grown up from kids to where we 131 00:06:45,519 --> 00:06:43,219 are today and some influences we've had 132 00:06:47,919 --> 00:06:45,529 Star Trek Wernher von Braun Space 133 00:06:49,299 --> 00:06:47,929 Shuttle Apollo you know what was your 134 00:06:50,229 --> 00:06:49,309 favorite Star Trek what you what do you 135 00:06:53,679 --> 00:06:50,239 want to be when you grew up 136 00:06:56,199 --> 00:06:53,689 Oh Captain Kirk who doesn't want to be 137 00:06:57,879 --> 00:06:56,209 Captain Kirk oh that was me man I wanted 138 00:07:00,069 --> 00:06:57,889 to be mr. Scott he was always fixing 139 00:07:01,700 --> 00:07:00,079 things and moving for right so again 140 00:07:04,310 --> 00:07:01,710 Glade grunt 141 00:07:06,680 --> 00:07:04,320 to be here serving and working but Tim 142 00:07:11,180 --> 00:07:06,690 how do we choose the right rocket 143 00:07:14,810 --> 00:07:11,190 take a little look at that what's the 144 00:07:17,660 --> 00:07:14,820 right rocket to launch a robot rockets 145 00:07:19,310 --> 00:07:17,670 come in lots of shapes and sizes so 146 00:07:22,220 --> 00:07:19,320 what's the right rocket for a space 147 00:07:24,740 --> 00:07:22,230 exploring robot choosing a rocket 148 00:07:28,450 --> 00:07:24,750 depends on three things how much the 149 00:07:33,230 --> 00:07:28,460 robot weighs how far away it's going and 150 00:07:35,690 --> 00:07:33,240 what it's going to do when the robot is 151 00:07:39,530 --> 00:07:35,700 small and light and stays close to study 152 00:07:42,020 --> 00:07:39,540 earth a small rocket is a-ok when the 153 00:07:44,240 --> 00:07:42,030 robot is large and heavy lots and lots 154 00:07:47,000 --> 00:07:44,250 of gear and travels far away in the 155 00:07:49,940 --> 00:07:47,010 solar system a big powerful rocket is 156 00:07:52,100 --> 00:07:49,950 what will do the job it's hard to find 157 00:07:54,470 --> 00:07:52,110 the perfect match but that's the mission 158 00:07:57,320 --> 00:07:54,480 of all the dedicated people in NASA's 159 00:07:59,710 --> 00:07:57,330 launch services program they've launched 160 00:08:02,510 --> 00:07:59,720 more than 200 rocket robot combos 161 00:08:08,150 --> 00:08:02,520 connecting us all to Discovery in the 162 00:08:09,620 --> 00:08:08,160 universe yet Tim we had to put that one 163 00:08:11,600 --> 00:08:09,630 out there just a little shout out for a 164 00:08:13,370 --> 00:08:11,610 launch services program you know make 165 00:08:15,980 --> 00:08:13,380 sure number one and number two Amanda 166 00:08:17,390 --> 00:08:15,990 Miscavige and Chuck Duvall who probably 167 00:08:19,520 --> 00:08:17,400 are watching this know that we're doing 168 00:08:21,470 --> 00:08:19,530 our job and the team at LSP is doing a 169 00:08:23,420 --> 00:08:21,480 great job from analysis to engineering 170 00:08:25,250 --> 00:08:23,430 to everything so great little plug there 171 00:08:26,600 --> 00:08:25,260 on how we pick our rockets but you know 172 00:08:28,610 --> 00:08:26,610 what's really important on what we do in 173 00:08:30,560 --> 00:08:28,620 LSP is we get to work with our 174 00:08:32,060 --> 00:08:30,570 commercial partners that's an important 175 00:08:33,200 --> 00:08:32,070 collaboration that we have Tim I know 176 00:08:35,570 --> 00:08:33,210 you'd like to talk about collaboration 177 00:08:38,090 --> 00:08:35,580 and especially the fleet of Rockets that 178 00:08:41,020 --> 00:08:38,100 we have in LSP yeah let's take a look at 179 00:08:44,810 --> 00:08:41,030 that fleet of rockets so there is a 180 00:08:47,300 --> 00:08:44,820 gorgeous picture it's one that I could 181 00:08:49,910 --> 00:08:47,310 just spend hours looking at who doesn't 182 00:08:51,920 --> 00:08:49,920 love rockets I mean my goodness 183 00:08:55,670 --> 00:08:51,930 here's a nice sampling of rockets that 184 00:08:57,290 --> 00:08:55,680 are some are in active now but as you 185 00:08:59,960 --> 00:08:57,300 move a little bit to the right there you 186 00:09:04,040 --> 00:08:59,970 see some of those incredible performers 187 00:09:06,610 --> 00:09:04,050 of today the Atlas 5 the Falcon 9 the 188 00:09:09,170 --> 00:09:06,620 Falcon Heavy and the delta 4 heavy and 189 00:09:11,270 --> 00:09:09,180 we got a little bit of a shout out to 190 00:09:13,940 --> 00:09:11,280 some of our future rockets on here as 191 00:09:14,780 --> 00:09:13,950 well Omega from Northrop Grumman as well 192 00:09:17,030 --> 00:09:14,790 as Blue Origin 193 00:09:19,760 --> 00:09:17,040 new Glenn what you see across the top 194 00:09:22,250 --> 00:09:19,770 there is the current fleet of LSP 195 00:09:24,710 --> 00:09:22,260 rockets that we have to choose from so 196 00:09:26,870 --> 00:09:24,720 when we're doing our job of matching up 197 00:09:29,540 --> 00:09:26,880 the science requirements for a 198 00:09:32,480 --> 00:09:29,550 spacecraft how big is it where does it 199 00:09:34,490 --> 00:09:32,490 need to go and we match that up with a 200 00:09:36,710 --> 00:09:34,500 launch vehicle and so we use our 201 00:09:38,060 --> 00:09:36,720 commercial partners to do that yeah 202 00:09:40,100 --> 00:09:38,070 that's him we had to show that one there 203 00:09:42,470 --> 00:09:40,110 a little bit and people probably notice 204 00:09:45,050 --> 00:09:42,480 the little symbol of mission complete 205 00:09:46,790 --> 00:09:45,060 for the Delta 2 right there and I had to 206 00:09:48,740 --> 00:09:46,800 put that in just for you my friend I 207 00:09:51,200 --> 00:09:48,750 know Delta 2 has a special place in your 208 00:09:53,060 --> 00:09:51,210 heart and you know we flew that last 209 00:09:55,670 --> 00:09:53,070 mission last year with icesat-2 and it 210 00:09:57,260 --> 00:09:55,680 was an awesome awesome mission I even 211 00:10:00,740 --> 00:09:57,270 got a model here for you too 212 00:10:02,950 --> 00:10:00,750 oh good little model of the Delta 2 just 213 00:10:06,830 --> 00:10:02,960 for you my friend right we can show our 214 00:10:08,720 --> 00:10:06,840 friends you got workhorse did wonderful 215 00:10:12,080 --> 00:10:08,730 things for our nation for so many years 216 00:10:13,940 --> 00:10:12,090 but fortunately we have other rockets to 217 00:10:15,470 --> 00:10:13,950 play with now mix so why don't you start 218 00:10:17,960 --> 00:10:15,480 talking to us about some of the current 219 00:10:19,280 --> 00:10:17,970 rockets we're still yes yeah Tim so you 220 00:10:20,540 --> 00:10:19,290 know what's really cool about the 221 00:10:21,440 --> 00:10:20,550 Rockets we get to work with and what 222 00:10:22,880 --> 00:10:21,450 we're here to talk about 223 00:10:25,520 --> 00:10:22,890 who doesn't love Rockets right we all 224 00:10:27,980 --> 00:10:25,530 love rockets but all Rockets have 225 00:10:30,200 --> 00:10:27,990 something in common even the new what I 226 00:10:32,240 --> 00:10:30,210 call new that everybody loves talk about 227 00:10:34,790 --> 00:10:32,250 the new Falcon Heavy the new SpaceX 228 00:10:36,230 --> 00:10:34,800 Falcon 9 even those Rockets have things 229 00:10:38,390 --> 00:10:36,240 in common with the Rockets we talked 230 00:10:39,680 --> 00:10:38,400 about and so let's look at some launch 231 00:10:41,390 --> 00:10:39,690 vehicle hardware because one of the 232 00:10:44,720 --> 00:10:41,400 things that they have in common right is 233 00:10:46,760 --> 00:10:44,730 they all have a first stage and a second 234 00:10:49,570 --> 00:10:46,770 stage from our smallest rocket the 235 00:10:52,190 --> 00:10:49,580 Pegasus XL which is a solid rocket motor 236 00:10:55,400 --> 00:10:52,200 vehicle that is dropped from a modified 237 00:10:57,740 --> 00:10:55,410 l-1011 and that carries out its mission 238 00:11:00,410 --> 00:10:57,750 from that to our mighty Atlas 5 that 239 00:11:01,610 --> 00:11:00,420 we're launching Mars 2020 on in July and 240 00:11:04,520 --> 00:11:01,620 we'll talk about that a little bit later 241 00:11:06,550 --> 00:11:04,530 to the mighty Delta 4 which is being 242 00:11:09,440 --> 00:11:06,560 used by our United States space force 243 00:11:11,660 --> 00:11:09,450 folks and and NASA had used that to 244 00:11:13,700 --> 00:11:11,670 launch some missions in previous years 245 00:11:15,350 --> 00:11:13,710 Parker Solar Probe comes to mind but 246 00:11:17,630 --> 00:11:15,360 every vehicle has something in common 247 00:11:20,780 --> 00:11:17,640 they need a fuel and they need an 248 00:11:22,670 --> 00:11:20,790 oxidizer right to get their engines 249 00:11:24,440 --> 00:11:22,680 going and you need something to combine 250 00:11:25,820 --> 00:11:24,450 those fuel and oxidizer and then you 251 00:11:27,680 --> 00:11:25,830 need something to ignite those so you 252 00:11:27,950 --> 00:11:27,690 need a little bit of flame so as we like 253 00:11:30,440 --> 00:11:27,960 to 254 00:11:33,050 --> 00:11:30,450 people Tim it's as simple and easy as 255 00:11:35,390 --> 00:11:33,060 the fire triangle right fuel oxidizer 256 00:11:37,010 --> 00:11:35,400 put a little heat with that very similar 257 00:11:39,080 --> 00:11:37,020 to that estie's rocket that you got 258 00:11:42,320 --> 00:11:39,090 behind you that you know starts a lot of 259 00:11:45,500 --> 00:11:42,330 people off right absolutely got a couple 260 00:11:47,360 --> 00:11:45,510 of s DS rockets right here and mick was 261 00:11:50,540 --> 00:11:47,370 telling you guys the simplicity of 262 00:11:52,430 --> 00:11:50,550 rockets is we've got to satisfy Newton's 263 00:11:54,440 --> 00:11:52,440 third law for every action there's an 264 00:11:56,120 --> 00:11:54,450 equal and opposite reaction we need to 265 00:11:58,460 --> 00:11:56,130 blow a whole lot of stuff out the 266 00:12:00,740 --> 00:11:58,470 tailpipe of these rockets to get them 267 00:12:02,690 --> 00:12:00,750 going in the other direction alright so 268 00:12:04,340 --> 00:12:02,700 the way we do that is we load them up 269 00:12:07,520 --> 00:12:04,350 with those propellants that make mention 270 00:12:11,180 --> 00:12:07,530 and fire triangle oxidizers and fuels 271 00:12:14,540 --> 00:12:11,190 and so what we do is we use we have to 272 00:12:16,790 --> 00:12:14,550 have an oxidizer and and a fuel on each 273 00:12:19,850 --> 00:12:16,800 stage and so Mik why don't you show in 274 00:12:22,610 --> 00:12:19,860 moral a more larger model with your 275 00:12:25,130 --> 00:12:22,620 Atlas 5 there the first stage of the 276 00:12:26,960 --> 00:12:25,140 Atlas 5 yes I've got an atlas 5 right 277 00:12:29,780 --> 00:12:26,970 here for folks on out there watching us 278 00:12:31,580 --> 00:12:29,790 NASA at home and that was five is made 279 00:12:34,730 --> 00:12:31,590 up of a first stage and the second stage 280 00:12:37,490 --> 00:12:34,740 this happens to be the Atlas 5 500 281 00:12:38,990 --> 00:12:37,500 series so the 5 metre fairing that you 282 00:12:41,840 --> 00:12:39,000 see up here which protects our payload 283 00:12:43,700 --> 00:12:41,850 also encompasses our second stage or on 284 00:12:45,290 --> 00:12:43,710 an Atlas is called a centaur so the 285 00:12:48,200 --> 00:12:45,300 second stage is actually inside this 286 00:12:50,300 --> 00:12:48,210 bearing but the first stage is this part 287 00:12:53,270 --> 00:12:50,310 right here and that first stage is made 288 00:12:55,910 --> 00:12:53,280 up of two tanks a fuel tank and an 289 00:12:58,370 --> 00:12:55,920 oxidizer tank and what do we use for 290 00:13:00,890 --> 00:12:58,380 fuel Tim it's a it's a it's a major 291 00:13:03,440 --> 00:13:00,900 industry secret across all vehicles 292 00:13:06,110 --> 00:13:03,450 including files and mattresses high-tech 293 00:13:08,990 --> 00:13:06,120 right how about stuff let's call it 294 00:13:10,430 --> 00:13:09,000 rocket propellant one that sounds cool 295 00:13:13,130 --> 00:13:10,440 that sounds pretty cool 296 00:13:16,970 --> 00:13:13,140 what would our grandmother call it high 297 00:13:18,920 --> 00:13:16,980 grade kerosene ah that's right yes it's 298 00:13:21,020 --> 00:13:18,930 kerosene fuel rocket propellant one it's 299 00:13:22,670 --> 00:13:21,030 awesome but then we have an oxidizer so 300 00:13:24,800 --> 00:13:22,680 we need to carry that oxidizer with us 301 00:13:27,020 --> 00:13:24,810 right to provide that and then providing 302 00:13:29,240 --> 00:13:27,030 ignition to get us off the off of Mother 303 00:13:31,550 --> 00:13:29,250 Earth and into space so we carry liquid 304 00:13:33,620 --> 00:13:31,560 oxygen rp1 and liquid oxygen in our 305 00:13:36,620 --> 00:13:33,630 first stage to be able to do that now 306 00:13:39,770 --> 00:13:36,630 some missions require just a little bit 307 00:13:41,290 --> 00:13:39,780 more power to get off of Earth 308 00:13:43,030 --> 00:13:41,300 so we strap-on 309 00:13:45,009 --> 00:13:43,040 solid rocket motors that's what these 310 00:13:47,740 --> 00:13:45,019 are right here solid rocket motors oh 311 00:13:50,050 --> 00:13:47,750 and what's ironic Tim likes to remind me 312 00:13:52,420 --> 00:13:50,060 all the time is my favorite vehicle here 313 00:13:54,850 --> 00:13:52,430 one of my favorite vehicles Atlas 5 the 314 00:13:57,040 --> 00:13:54,860 solid rocket motors are about 60 inches 315 00:13:59,110 --> 00:13:57,050 in diameter one of my other favorite 316 00:14:01,329 --> 00:13:59,120 vehicles is the Pegasus XL which we 317 00:14:03,280 --> 00:14:01,339 talked about which is a solid rocket 318 00:14:04,240 --> 00:14:03,290 motor vehicle in itself but it's only 50 319 00:14:06,400 --> 00:14:04,250 inches in diameter 320 00:14:08,410 --> 00:14:06,410 so Tim always likes to tell me that one 321 00:14:11,139 --> 00:14:08,420 of these solids is like the first stage 322 00:14:12,639 --> 00:14:11,149 of my Pegasus and you know we got to 323 00:14:14,319 --> 00:14:12,649 deal with what we got to deal with to 324 00:14:15,970 --> 00:14:14,329 get our payload customers into orbit 325 00:14:17,380 --> 00:14:15,980 that's our that's our job right this is 326 00:14:19,449 --> 00:14:17,390 our public service announcement right 327 00:14:21,370 --> 00:14:19,459 Tim our job is to get our payload 328 00:14:25,150 --> 00:14:21,380 customers into orbit safely and on time 329 00:14:28,030 --> 00:14:25,160 using the rockets that we love to work 330 00:14:30,639 --> 00:14:28,040 with so that must have been our public 331 00:14:33,550 --> 00:14:30,649 service moment where we do have to pause 332 00:14:35,819 --> 00:14:33,560 Nick and I love Rockets so much but we 333 00:14:39,220 --> 00:14:35,829 do have to catch ourselves and pause and 334 00:14:41,620 --> 00:14:39,230 remember that guess what if it wasn't 335 00:14:44,860 --> 00:14:41,630 for our spacecraft customers we wouldn't 336 00:14:47,410 --> 00:14:44,870 have jobs and so we absolutely are laser 337 00:14:49,840 --> 00:14:47,420 focused on mission success for our 338 00:14:51,550 --> 00:14:49,850 spacecraft and what they need to do in 339 00:14:54,060 --> 00:14:51,560 space what they need to do when they're 340 00:14:57,790 --> 00:14:54,070 on orbit or heading to other planets 341 00:15:00,310 --> 00:14:57,800 absolutely I think that's enough right 342 00:15:01,900 --> 00:15:00,320 now weekly weather yeah we love our 343 00:15:04,210 --> 00:15:01,910 spacecraft customers but we're all about 344 00:15:06,040 --> 00:15:04,220 Rockets so second stage second stage 345 00:15:10,090 --> 00:15:06,050 same thing right we need a fuel and an 346 00:15:11,889 --> 00:15:10,100 oxidizer so what do we use anybody you 347 00:15:14,769 --> 00:15:11,899 want to guess Tim what is what is our 348 00:15:17,710 --> 00:15:14,779 fuel oh gosh oh we go 349 00:15:21,970 --> 00:15:17,720 should we try let's try something super 350 00:15:27,010 --> 00:15:21,980 cold Nick what do you say okay how about 351 00:15:28,540 --> 00:15:27,020 we go with liquid hydrogen oh how cool 352 00:15:31,150 --> 00:15:28,550 do you have to get that liquid hydrogen 353 00:15:33,910 --> 00:15:31,160 make very very cold Tim down into the 354 00:15:35,769 --> 00:15:33,920 minus minus temperatures colder than you 355 00:15:37,840 --> 00:15:35,779 ever want to experience you know for 356 00:15:40,210 --> 00:15:37,850 that but you know we cleanly like 357 00:15:42,370 --> 00:15:40,220 hydrogen go ahead 358 00:15:44,259 --> 00:15:42,380 oxygen on the first stage and liquid 359 00:15:47,199 --> 00:15:44,269 oxygen on the second stage those are 360 00:15:51,280 --> 00:15:47,209 about minus 300 degrees Fahrenheit and 361 00:15:52,960 --> 00:15:51,290 then to liquefy hydrogen you got to go 362 00:15:53,920 --> 00:15:52,970 about another hundred degrees so it's 363 00:15:56,940 --> 00:15:53,930 about minus 364 00:15:59,860 --> 00:15:56,950 or 15 minus 420 degrees Fahrenheit 365 00:16:01,960 --> 00:15:59,870 cryogenics they're wonderful very 366 00:16:03,880 --> 00:16:01,970 wonderful very wonderful so but hey guys 367 00:16:05,410 --> 00:16:03,890 sneaked him he talked about this I 368 00:16:06,690 --> 00:16:05,420 wanted to be the first thing he only had 369 00:16:09,820 --> 00:16:06,700 a question lemon I wanted to ask 370 00:16:11,740 --> 00:16:09,830 somebody asked why is it that we reuse 371 00:16:14,199 --> 00:16:11,750 some Rockets some Rockets actually fly 372 00:16:15,040 --> 00:16:14,209 back to be reused and others just fall 373 00:16:21,180 --> 00:16:15,050 into the ocean 374 00:16:25,840 --> 00:16:24,610 so yeah actually it's it's cool we Tim 375 00:16:28,449 --> 00:16:25,850 and I've been around long enough we have 376 00:16:30,940 --> 00:16:28,459 actually seen the industry changed when 377 00:16:32,800 --> 00:16:30,950 we first started out launch vehicles 378 00:16:34,329 --> 00:16:32,810 were called expendable matter-of-fact 379 00:16:36,850 --> 00:16:34,339 launch services program was called the 380 00:16:39,430 --> 00:16:36,860 expendable launch vehicle program in our 381 00:16:42,220 --> 00:16:39,440 early days when we first started in 1998 382 00:16:44,590 --> 00:16:42,230 here at Kennedy Space Center so a lot of 383 00:16:47,260 --> 00:16:44,600 vehicles we're launching satellites and 384 00:16:49,960 --> 00:16:47,270 Kham Kham probes things like that and 385 00:16:51,850 --> 00:16:49,970 they were just thrown away now we had 386 00:16:55,590 --> 00:16:51,860 some people come on board people were 387 00:16:58,360 --> 00:16:55,600 studying reuse for many many years and 388 00:17:00,610 --> 00:16:58,370 SpaceX is what most people refer to or 389 00:17:03,070 --> 00:17:00,620 look at they started looking at how they 390 00:17:05,049 --> 00:17:03,080 could reuse their first stages and it 391 00:17:06,790 --> 00:17:05,059 came down to if you could reuse your 392 00:17:08,439 --> 00:17:06,800 first stage you could turn your rocket 393 00:17:10,990 --> 00:17:08,449 around faster and get your customers 394 00:17:12,760 --> 00:17:11,000 back on orbit quicker and so you could 395 00:17:14,770 --> 00:17:12,770 launch more in a year which we've seen 396 00:17:17,890 --> 00:17:14,780 SpaceX do in the last couple years so 397 00:17:20,049 --> 00:17:17,900 it's a real change in the industry to be 398 00:17:21,669 --> 00:17:20,059 able to start seeing us reuse hardware 399 00:17:24,040 --> 00:17:21,679 there's a lot that goes along with 400 00:17:26,130 --> 00:17:24,050 reusing hardware and NASA launch 401 00:17:28,510 --> 00:17:26,140 services program and our contractor 402 00:17:30,010 --> 00:17:28,520 SpaceX in this case we are working very 403 00:17:33,370 --> 00:17:30,020 closely together and make sure we can 404 00:17:34,330 --> 00:17:33,380 have best benefit with reuse so last one 405 00:17:37,090 --> 00:17:34,340 for now and I'll let you guys get back 406 00:17:38,919 --> 00:17:37,100 to it somebody asked why do you have 407 00:17:40,960 --> 00:17:38,929 stages to a rocket doesn't that add 408 00:17:44,380 --> 00:17:40,970 extra complexity a chance for something 409 00:17:48,840 --> 00:17:44,390 to go wrong I'll let our launch manager 410 00:17:52,690 --> 00:17:48,850 answer that one so that was just basic 411 00:17:57,580 --> 00:17:52,700 rocket theory on being able to get the 412 00:18:00,250 --> 00:17:57,590 most mass into orbit most eloquently and 413 00:18:01,930 --> 00:18:00,260 easily so what you want to do josh is 414 00:18:03,490 --> 00:18:01,940 you've got it you've got to be keep 415 00:18:07,180 --> 00:18:03,500 throwing stuff out of the tailpipe of 416 00:18:07,700 --> 00:18:07,190 these Rockets continually right so what 417 00:18:09,590 --> 00:18:07,710 happens 418 00:18:12,860 --> 00:18:09,600 when you've loaded up did an incredible 419 00:18:15,019 --> 00:18:12,870 huge tank but now it's only a third full 420 00:18:17,419 --> 00:18:15,029 well you're still having to carry the 421 00:18:20,210 --> 00:18:17,429 mass of the rest of that empty tank with 422 00:18:23,990 --> 00:18:20,220 you onto orbit so the early rocketeers 423 00:18:27,110 --> 00:18:24,000 dr. Goddard and in the early 20th 424 00:18:29,630 --> 00:18:27,120 century said what if once you burned out 425 00:18:31,130 --> 00:18:29,640 that portion of propellant in the rocket 426 00:18:33,730 --> 00:18:31,140 what if you threw that part of the 427 00:18:37,310 --> 00:18:33,740 rocket away and then you focused on 428 00:18:39,139 --> 00:18:37,320 continuing on into flight and so when 429 00:18:41,090 --> 00:18:39,149 you look at the rocket equation one of 430 00:18:43,310 --> 00:18:41,100 the basic equations on how you manage 431 00:18:45,500 --> 00:18:43,320 the mass of the rocket versus the mass 432 00:18:48,710 --> 00:18:45,510 of the propellant versus the tiny little 433 00:18:50,539 --> 00:18:48,720 mass of the spacecraft it made much more 434 00:18:53,330 --> 00:18:50,549 sense in it was the perfect solution 435 00:18:55,460 --> 00:18:53,340 what to throw that expended mass away as 436 00:18:57,919 --> 00:18:55,470 soon as you could and focus on the 437 00:18:59,960 --> 00:18:57,929 performance of your engine once it's now 438 00:19:02,389 --> 00:18:59,970 either in the space environment or much 439 00:19:04,519 --> 00:19:02,399 closer so it's much more matched for 440 00:19:06,590 --> 00:19:04,529 that cool that's awesome guys thinks 441 00:19:08,870 --> 00:19:06,600 I'll let you get back to it all right 442 00:19:10,549 --> 00:19:08,880 really quick we're gonna wrap up real 443 00:19:12,049 --> 00:19:10,559 launch beautiful hard real quick because 444 00:19:13,970 --> 00:19:12,059 we've talked first stage we've talked 445 00:19:16,190 --> 00:19:13,980 second stage but and we also talked to 446 00:19:17,870 --> 00:19:16,200 our spacecraft spacecraft customer Tim 447 00:19:19,430 --> 00:19:17,880 but one of the important things to 448 00:19:21,409 --> 00:19:19,440 protect our spacecraft customer on 449 00:19:23,600 --> 00:19:21,419 ascent into space is we have to have 450 00:19:25,010 --> 00:19:23,610 that payload fairing that we see on top 451 00:19:26,899 --> 00:19:25,020 of the rocket right to make sure that 452 00:19:29,389 --> 00:19:26,909 everything is protected 453 00:19:31,100 --> 00:19:29,399 before we enter outer space there and so 454 00:19:32,659 --> 00:19:31,110 that's another thing we do on the 455 00:19:35,750 --> 00:19:32,669 vehicle to make it aerodynamic and 456 00:19:38,090 --> 00:19:35,760 protect our payload customer so that's 457 00:19:39,680 --> 00:19:38,100 basics that's the basics of launch 458 00:19:42,409 --> 00:19:39,690 vehicle hardware right there first stage 459 00:19:44,510 --> 00:19:42,419 second stage fuel oxidizer basic fire 460 00:19:48,070 --> 00:19:44,520 triangle just like a lot of you at home 461 00:19:49,940 --> 00:19:48,080 who play with sd's rockets you guys 462 00:19:52,460 --> 00:19:49,950 experience that every time you light one 463 00:19:54,409 --> 00:19:52,470 off it's a solid rocket motor and it's 464 00:19:56,419 --> 00:19:54,419 built it's got a fuel and oxidizer built 465 00:19:58,039 --> 00:19:56,429 in and you can launch that rocket and 466 00:19:59,690 --> 00:19:58,049 get your payload into where you need to 467 00:20:01,940 --> 00:19:59,700 be but you know 10 having all these 468 00:20:05,389 --> 00:20:01,950 rockets one of the things we love to do 469 00:20:07,070 --> 00:20:05,399 in LSP with our customers is we like to 470 00:20:07,970 --> 00:20:07,080 explore like we talked earlier why 471 00:20:10,100 --> 00:20:07,980 Rockets right 472 00:20:11,930 --> 00:20:10,110 we like to explore the universe and as 473 00:20:15,049 --> 00:20:11,940 you can see on the screen right now we 474 00:20:17,960 --> 00:20:15,059 in LSP have launched quite a few 475 00:20:19,590 --> 00:20:17,970 satellites to explore our universe and 476 00:20:21,900 --> 00:20:19,600 to get to learn and know 477 00:20:24,120 --> 00:20:21,910 about what's going on with the planets 478 00:20:26,460 --> 00:20:24,130 and the Sun and things are doing but 479 00:20:28,350 --> 00:20:26,470 most importantly I think you can see Tim 480 00:20:30,630 --> 00:20:28,360 what's our favorite place to study right 481 00:20:32,550 --> 00:20:30,640 there oh if you guys look at all of 482 00:20:36,030 --> 00:20:32,560 those missions in that box 483 00:20:39,120 --> 00:20:36,040 those are all dedicated to who doesn't 484 00:20:42,630 --> 00:20:39,130 love their mother planet Earth and so 485 00:20:46,200 --> 00:20:42,640 you see in the 21 year history of LSP 486 00:20:49,170 --> 00:20:46,210 we've launched 92 missions near and far 487 00:20:51,780 --> 00:20:49,180 from the Sun out to Pluto but we dearly 488 00:20:54,390 --> 00:20:51,790 love this planet that we all live on and 489 00:20:56,880 --> 00:20:54,400 absolutely love the earth science 490 00:20:58,500 --> 00:20:56,890 missions that we work absolutely Tim and 491 00:20:59,550 --> 00:20:58,510 you know one of one of the things we've 492 00:21:01,890 --> 00:20:59,560 done over the years we've had some 493 00:21:04,530 --> 00:21:01,900 notable missions as launch services 494 00:21:06,000 --> 00:21:04,540 program and some of those have been you 495 00:21:08,880 --> 00:21:06,010 and I've been part of those notable 496 00:21:10,980 --> 00:21:08,890 missions and they include Pluto New 497 00:21:12,690 --> 00:21:10,990 Horizons Parker Solar Probe that I 498 00:21:14,610 --> 00:21:12,700 talked about but some of our favorite 499 00:21:17,580 --> 00:21:14,620 ones are theirs are those little Mars 500 00:21:20,820 --> 00:21:17,590 rovers right Mars Pathfinder Sojourner 501 00:21:23,910 --> 00:21:20,830 oh yes Spirit and Opportunity that we 502 00:21:25,890 --> 00:21:23,920 launched in back in 2003 and about nine 503 00:21:28,320 --> 00:21:25,900 years ago we launched the Curiosity 504 00:21:30,450 --> 00:21:28,330 rover and it's still crawling around on 505 00:21:33,240 --> 00:21:30,460 the surface of Mars returning incredible 506 00:21:34,740 --> 00:21:33,250 science and images to us and guess what 507 00:21:36,270 --> 00:21:34,750 we're doing this summer Mik why don't 508 00:21:36,780 --> 00:21:36,280 you tell the folks so you know what 509 00:21:39,360 --> 00:21:36,790 we're doing 510 00:21:40,590 --> 00:21:39,370 July of this year we are so excited to 511 00:21:43,560 --> 00:21:40,600 be getting ready to launch the next 512 00:21:45,360 --> 00:21:43,570 probe to Mars to start things on for man 513 00:21:47,670 --> 00:21:45,370 to moon and man to Mars and that is Mars 514 00:21:50,850 --> 00:21:47,680 2020 right there you see a picture of 515 00:21:53,490 --> 00:21:50,860 Mars 2020 Rover that is being prepped 516 00:21:57,120 --> 00:21:53,500 and ready to go for launch this summer 517 00:21:58,800 --> 00:21:57,130 and we're just so excited about that Tim 518 00:22:00,450 --> 00:21:58,810 but you know what's cool about Mars 519 00:22:02,790 --> 00:22:00,460 slight sway and I know you love this 520 00:22:04,560 --> 00:22:02,800 because we talk about it every day in 521 00:22:07,380 --> 00:22:04,570 the office when we're in the office and 522 00:22:10,650 --> 00:22:07,390 when you call me on the Skype also and 523 00:22:12,810 --> 00:22:10,660 the team's but this Rover has a special 524 00:22:14,340 --> 00:22:12,820 little buddy that's going along with it 525 00:22:17,550 --> 00:22:14,350 and what is that Tim what is it you love 526 00:22:18,900 --> 00:22:17,560 so back on the rover for just a second 527 00:22:22,260 --> 00:22:18,910 Josh if you could throw the picture of 528 00:22:23,730 --> 00:22:22,270 that we are really pleased up to now we 529 00:22:27,120 --> 00:22:23,740 have only been able to call this 530 00:22:29,340 --> 00:22:27,130 gorgeous piece of equipment Mars 2020 531 00:22:31,110 --> 00:22:29,350 but about a month ago we released the 532 00:22:33,149 --> 00:22:31,120 name for this Rover and its first 533 00:22:36,029 --> 00:22:33,159 appearance so Kure 534 00:22:38,729 --> 00:22:36,039 city will be joined by perseverance once 535 00:22:41,580 --> 00:22:38,739 we launched in July and transit to Mars 536 00:22:44,249 --> 00:22:41,590 and that one additional thing that we're 537 00:22:47,009 --> 00:22:44,259 taking on the Mars 2020 perseverance 538 00:22:49,710 --> 00:22:47,019 mission is this it's going to be 539 00:22:52,399 --> 00:22:49,720 strapped to the belly of the Mars rover 540 00:22:55,409 --> 00:22:52,409 so after we we land on the planet 541 00:22:57,479 --> 00:22:55,419 checkout the rover we're gonna drop that 542 00:23:00,119 --> 00:22:57,489 helicopter onto the surface of Mars 543 00:23:03,629 --> 00:23:00,129 drive the rover perseverance away and 544 00:23:05,700 --> 00:23:03,639 then fly and get some beautiful aerial 545 00:23:08,879 --> 00:23:05,710 shots first time ever we're gonna have 546 00:23:11,639 --> 00:23:08,889 aerial video of another planet just 547 00:23:14,399 --> 00:23:11,649 amazing amazing it's so excited for that 548 00:23:16,769 --> 00:23:14,409 mission and the folks at JPL and you 549 00:23:19,320 --> 00:23:16,779 know Josh before we turn it back over to 550 00:23:21,029 --> 00:23:19,330 you Tim and I just want to give a shout 551 00:23:23,729 --> 00:23:21,039 out to our NASA family our launch 552 00:23:25,830 --> 00:23:23,739 services program family NASA at home you 553 00:23:28,469 --> 00:23:25,840 know perseverance is an appropriate name 554 00:23:30,539 --> 00:23:28,479 for that Rover as we are all persevering 555 00:23:32,279 --> 00:23:30,549 through this time working from home and 556 00:23:34,680 --> 00:23:32,289 being where we're at and separated 557 00:23:37,440 --> 00:23:34,690 launch services program our NASA family 558 00:23:39,899 --> 00:23:37,450 at KSC we are truly an integrated family 559 00:23:42,149 --> 00:23:39,909 and we kind of miss seeing everybody so 560 00:23:43,619 --> 00:23:42,159 we thank you and the PIO team for 561 00:23:46,320 --> 00:23:43,629 putting these series together and 562 00:23:50,190 --> 00:23:46,330 allowing us to join you today thanks so 563 00:23:52,080 --> 00:23:50,200 much for having us yeah yeah thanks guys 564 00:23:53,609 --> 00:23:52,090 a couple more questions before you go 565 00:23:55,169 --> 00:23:53,619 before I let you go 566 00:23:56,909 --> 00:23:55,179 the first one was do you have any 567 00:23:59,399 --> 00:23:56,919 personal favorite missions and I'll 568 00:24:02,009 --> 00:23:59,409 leave that pretty broad could be past or 569 00:24:03,539 --> 00:24:02,019 future or maybe present ones that come 570 00:24:05,249 --> 00:24:03,549 to mind is main like that was fun to 571 00:24:10,979 --> 00:24:05,259 work or what a cool thing to be a part 572 00:24:14,430 --> 00:24:10,989 of make I'll let you take well I'll 573 00:24:16,739 --> 00:24:14,440 start off with all the missions I've 574 00:24:19,409 --> 00:24:16,749 worked as a vehicle systems engineer 575 00:24:21,839 --> 00:24:19,419 prior to becoming chief of fleet systems 576 00:24:24,690 --> 00:24:21,849 and that we continue to work in launch 577 00:24:27,629 --> 00:24:24,700 services program with my team of vehicle 578 00:24:28,830 --> 00:24:27,639 folks are exciting but a couple of my 579 00:24:30,779 --> 00:24:28,840 personal favorites 580 00:24:32,149 --> 00:24:30,789 that I was actually on console for and 581 00:24:35,129 --> 00:24:32,159 spent a lot of time working is 582 00:24:37,799 --> 00:24:35,139 absolutely Pluto New Horizons which was 583 00:24:40,289 --> 00:24:37,809 our first Atlas 5 500 series for launch 584 00:24:41,579 --> 00:24:40,299 services program I thought that was 585 00:24:44,759 --> 00:24:41,589 really cool to be able to work that 586 00:24:46,409 --> 00:24:44,769 mission and see what happened and what 587 00:24:48,629 --> 00:24:46,419 we could do to study Pluto and 588 00:24:51,239 --> 00:24:48,639 and ironically we launched that mission 589 00:24:53,460 --> 00:24:51,249 to go study Pluto and a couple weeks 590 00:24:55,109 --> 00:24:53,470 after we launched it was noted we were 591 00:24:58,470 --> 00:24:55,119 notified that Pluto was no longer a 592 00:25:00,419 --> 00:24:58,480 planet but it was a lot of fun a lot of 593 00:25:02,369 --> 00:25:00,429 time a lot of good times working with 594 00:25:04,560 --> 00:25:02,379 the LSP family on that mission that was 595 00:25:06,389 --> 00:25:04,570 one of my favorites the second one that 596 00:25:11,009 --> 00:25:06,399 I have up there that ranks right up 597 00:25:14,249 --> 00:25:11,019 there is the I set chipset mission on 598 00:25:16,080 --> 00:25:14,259 our Delta 2 it was my first Delta 2 that 599 00:25:18,210 --> 00:25:16,090 I got to join the Delta 2 family and 600 00:25:19,739 --> 00:25:18,220 work alongside Tim and and some of the 601 00:25:22,049 --> 00:25:19,749 folks that had done that at United 602 00:25:24,629 --> 00:25:22,059 Launch Alliance it was great to work 603 00:25:26,249 --> 00:25:24,639 that mission Delta 2 as Tim said was a 604 00:25:28,769 --> 00:25:26,259 workhorse for NASA through all those 605 00:25:31,859 --> 00:25:28,779 years and just be able to get to know 606 00:25:33,599 --> 00:25:31,869 our contractors at SpaceX ula Northrop 607 00:25:35,759 --> 00:25:33,609 Grumman and working with them on the 608 00:25:37,830 --> 00:25:35,769 vehicles has always been fun and of 609 00:25:39,720 --> 00:25:37,840 course I spent my last several years 610 00:25:41,759 --> 00:25:39,730 working with the folks at Northrop 611 00:25:44,399 --> 00:25:41,769 Grumman on the Pegasus XL mission and 612 00:25:47,310 --> 00:25:44,409 all of the missions and all of those 613 00:25:50,669 --> 00:25:47,320 have been very a lot of fun for me as a 614 00:25:53,099 --> 00:25:50,679 vehicle guy and achieve work in that 615 00:25:55,979 --> 00:25:53,109 that small vehicle so across the board 616 00:25:57,149 --> 00:25:55,989 Joshua I really like them all as we 617 00:25:59,879 --> 00:25:57,159 started this whole thing out 618 00:26:01,769 --> 00:25:59,889 I just love rockets and being able to go 619 00:26:04,109 --> 00:26:01,779 to work and work with rockets everything 620 00:26:07,619 --> 00:26:04,119 is what it's all about so Tim your 621 00:26:10,019 --> 00:26:07,629 favorite yeah I mean I uh I totally 622 00:26:11,609 --> 00:26:10,029 agree with Nick they all are unique and 623 00:26:15,389 --> 00:26:11,619 we love them all it's kind of like your 624 00:26:20,299 --> 00:26:15,399 kids you love them all and the one thing 625 00:26:24,960 --> 00:26:20,309 is working with all of the team each 626 00:26:27,180 --> 00:26:24,970 their own individual team and flavor we 627 00:26:28,830 --> 00:26:27,190 couple that with our LSP team and then 628 00:26:32,249 --> 00:26:28,840 our range support that we get from the 629 00:26:34,169 --> 00:26:32,259 United States space force and all of our 630 00:26:37,970 --> 00:26:34,179 contractors that help us do what we do 631 00:26:41,009 --> 00:26:37,980 just a few that I would mention would be 632 00:26:44,729 --> 00:26:41,019 going back about four years we launched 633 00:26:47,009 --> 00:26:44,739 osiris-rex which is circling an asteroid 634 00:26:49,590 --> 00:26:47,019 asteroid Bennu right now and later this 635 00:26:52,560 --> 00:26:49,600 year it's going to touchdown grab some 636 00:26:55,859 --> 00:26:52,570 asteroid dust and actually bring it back 637 00:26:58,739 --> 00:26:55,869 to earth in a few years so we launched 638 00:26:59,270 --> 00:26:58,749 that on an Atlas 5 I can think of the 639 00:27:00,620 --> 00:26:59,280 gray 640 00:27:04,700 --> 00:27:00,630 mission that we launched to the moon 641 00:27:06,980 --> 00:27:04,710 back in 2011 the two sent two probes to 642 00:27:09,740 --> 00:27:06,990 study the gravity of the moon that was a 643 00:27:12,440 --> 00:27:09,750 lot of fun and then make mention his 644 00:27:15,410 --> 00:27:12,450 first mission on Delta 2 that ice that 645 00:27:17,090 --> 00:27:15,420 chips at mission and I'll mention what 646 00:27:19,790 --> 00:27:17,100 we launched just just under two years 647 00:27:23,030 --> 00:27:19,800 ago the icesat-2 mission which was the 648 00:27:25,880 --> 00:27:23,040 very final mission on delta ii that was 649 00:27:28,340 --> 00:27:25,890 a lot of fun mainly because it brought 650 00:27:32,510 --> 00:27:28,350 so many people back together for one 651 00:27:34,670 --> 00:27:32,520 last farewell and great performance from 652 00:27:37,280 --> 00:27:34,680 the work course before we close the book 653 00:27:39,710 --> 00:27:37,290 on that great launch vehicle yeah and 654 00:27:42,470 --> 00:27:39,720 Josh I just go back real quick to the 655 00:27:44,960 --> 00:27:42,480 reuse thing one of my other favourite 656 00:27:47,660 --> 00:27:44,970 missions recent that was in recent years 657 00:27:50,240 --> 00:27:47,670 was our test mission heading out to 658 00:27:52,400 --> 00:27:50,250 study exoplanets and we've seen some 659 00:27:54,710 --> 00:27:52,410 great photos from that and you know 660 00:27:57,890 --> 00:27:54,720 that's been a lot of fun working with 661 00:28:00,530 --> 00:27:57,900 our space spacex contractor they're from 662 00:28:02,000 --> 00:28:00,540 a commercial side learning how they do 663 00:28:03,530 --> 00:28:02,010 business like I said earlier they've 664 00:28:06,530 --> 00:28:03,540 turned the industry on its ear a little 665 00:28:08,990 --> 00:28:06,540 bit on how we do rocket stuff and so 666 00:28:11,300 --> 00:28:09,000 it's been looked fun as NASA LSP to 667 00:28:13,400 --> 00:28:11,310 learn what they do and and how we can 668 00:28:15,860 --> 00:28:13,410 become more agile and more efficient and 669 00:28:17,660 --> 00:28:15,870 doing our job so again overall they're 670 00:28:19,550 --> 00:28:17,670 they're all great missions and I know 671 00:28:22,670 --> 00:28:19,560 the LSP family looks forward to every 672

to 686 00:28:57,200 --> 00:28:53,430 talk about kind of a part of the NASA at 687 00:28:59,600 --> 00:28:57,210 home effort nasa.gov slash NASA at home 688 00:29:00,860 --> 00:28:59,610 want to highlight a couple things for 689 00:29:04,190 --> 00:29:00,870 you really quickly so this is that main 690 00:29:04,670 --> 00:29:04,200 page if you do go to nasa.gov slash NASA 691 00:29:06,860 --> 00:29:04,680 at home 692 00:29:08,240 --> 00:29:06,870 that's that page you see and trying to 693 00:29:09,650 --> 00:29:08,250 highlight something every episode the 694 00:29:12,289 --> 00:29:09,660 specific thing I wanted to highlight 695 00:29:13,909 --> 00:29:12,299 this time is in the virtual tour section 696 00:29:15,739 --> 00:29:13,919 the Commercial Crew program which I 697 00:29:18,829 --> 00:29:15,749 think Nick mentioned this that we have 698 00:29:20,389 --> 00:29:18,839 crews flying into Earth orbit low-earth 699 00:29:22,089 --> 00:29:20,399 orbit for the first time in nine years 700 00:29:24,619 --> 00:29:22,099 this summer coming up very very soon 701 00:29:26,299 --> 00:29:24,629 incredibly excited we have actually put 702 00:29:28,459 --> 00:29:26,309 together some virtual tours related to 703 00:29:31,339 --> 00:29:28,469 Commercial Crew this is one of them that 704 00:29:33,919 --> 00:29:31,349 actually ties specifically to astronaut 705 00:29:35,629 --> 00:29:33,929 training so this is here this is a good 706 00:29:36,799 --> 00:29:35,639 colleague of mine Rachel Power who's 707 00:29:38,749 --> 00:29:36,809 working on some of the stem at home 708 00:29:40,369 --> 00:29:38,759 stuff and this is actually a chance to 709 00:29:43,129 --> 00:29:40,379 kind of go inside the neutral buoyancy 710 00:29:45,560 --> 00:29:43,139 lab one of the largest swimming pools in 711 00:29:46,789 --> 00:29:45,570 the world to get to experience a little 712 00:29:50,690 --> 00:29:46,799 bit of what the astronauts go through 713 00:29:53,659 --> 00:29:50,700 for training all right so that is gonna 714 00:29:55,759 --> 00:29:53,669 do it for us for today please continue 715 00:29:57,440 --> 00:29:55,769 to send your questions to hashtag NASA 716 00:29:57,949 --> 00:29:57,450 at home but from the Kennedy Space 717 00:30:00,919 --> 00:29:57,959 Center 718 00:30:03,680 --> 00:30:00,929 sort of I'm Joshua with Santora this is 719 00:30:05,629 -->
