00:00:03,340 --> 00:00:04,148 exciting time 4 00:00:04,148 --> 00:00:04,788 where the number 5 00:00:04,788 --> 00:00:06,028 of crude vehicles 6 00:00:06,028 --> 00:00:07,771 going to the international space station 7 00:00:07,828 --> 00:00:10,131 we'll go from just one to three 8 00:00:10,428 --> 00:00:12,108 the soyuz is eight year 9 00:00:12,108 --> 00:00:13,588 monopoly for getting humans up 10 00:00:13,588 --> 00:00:15,011 to the international space station 11 00:00:15,510 --> 00:00:16,833 is finally coming to an end 12 00:00:16,946 --> 00:00:19,346 so today we're gonna take a deep dive on the two 13 00:00:19,346 --> 00:00:21,186 new spaceships that are going to be responsible 14 00:00:21,186 --> 00:00:22,386 for taking humans to 15 00:00:22,386 --> 00:00:22,993 and from 16 00:00:23,346 --> 00:00:25,873 the international space station from the United States 17 00:00:26,100 --> 00:00:27,494 so we're gonna compare the bowing star line 18 00:00:27,494 --> 00:00:29,051 or writing an atlas 5 rocket 19 00:00:29,068 --> 00:00:31,840 to spacex's crew dragon on their falcon 9 rocket 20 00:00:31,840 --> 00:00:32,508 and to see how 21 00:00:32,508 --> 00:00:34,708 far we've progressed in the world of human spaceflight 22 00:00:34,708 --> 00:00:36,251 we're also gonna compare all these 23 00:00:36,268 --> 00:00:36,960 systems alongside 24 00:00:36,960 --> 00:00:37,960 russia's soyuz capsule 25 00:00:37,960 --> 00:00:39,800 and the United States has retired space shuttle 26 00:00:39,800 --> 00:00:41,228 in a side by side comparison 27 00:00:41,228 --> 00:00:42,548 we'll take a look at the designs 28 00:00:42,548 --> 00:00:44,508 the rockets they ride the dimensions 29 00:00:44,508 --> 00:00:46,091 the cost the safety consideration 30 00:00:46,502 --> 00:00:49,406 and any other unique feature that each vehicle offers 31 00:00:49,406 --> 00:00:50,246 considering I've been 32 00:00:50,246 --> 00:00:52,293 up close and personal with spacex's crew 33 00:00:52,293 --> 00:00:53,173 dragon capsule 34 00:00:53,206 --> 00:00:54,533 and boeing starling 35 00:00:55,006 --> 00:00:55,846 I think I've got some pretty 36 00:00:55,846 --> 00:00:57,053 good insight on these vehicles 37 00:00:57,366 --> 00:00:58,253 let's get started 38 00:01:09,080 --> 00:01:10,950 the international space station is 39 00:01:10,950 --> 00:01:13,810 still one of the greatest feats of human engineering 40 00:01:13,870 --> 00:01:14,530 I mean after all 41 00:01:14,530 --> 00:01:17,490 it's a football field sized floating laboratory 42 00:01:17,620 --> 00:01:19,810 traveling 10 times faster than a bullet 43 00:01:19,870 --> 00:01:20,870 circling the earth 44 00:01:20,870 --> 00:01:22,410 every 90 minutes 45 00:01:22,590 --> 00:01:23,170 is taken 46 00:01:23,170 --> 00:01:25,991 33 launches to put all of its pieces into orbit 47 00:01:26,028 --> 00:01:29,071 and has been home to over 230 people 48 00:01:29,308 --> 00:01:30,911 from almost 20 countries 49 00:01:30,948 --> 00:01:33,991 the iss typically has six astronauts on board 50 00:01:34,108 --> 00:01:35,631 crew are sent up in groups of three 51 00:01:35,868 --> 00:01:38,631 and usually reside of the station for six months 52 00:01:38,910 --> 00:01:39,648 there is typically 53 00:01:39,648 --> 00:01:42,048 a three month overlap for existing crew 54 00:01:42,048 --> 00:01:43,528 and newly arriving crew 55 00:01:43,528 --> 00:01:46,451 but since the space shuttle program ended in 2011 56 00:01:46,568 --> 00:01:49,891 there's only been a single ride to the iss 57 00:01:50,310 --> 00:01:52,049 that's russia's soyuz vehicle 58 00:01:52,049 --> 00:01:53,450 but we're coming up on a really 59 00:01:53,450 --> 00:01:54,169 exciting time 60 00:01:54,169 --> 00:01:56,729 as the United States prepares to send us astronauts 61 00:01:56,729 --> 00:02:00,050 to the international space station from us soil on two 62 00:02:00,209 --> 00:02:01,810 brand new spaceships 63 00:02:01,860 --> 00:02:03,200 and what I think is most exciting is 64 00:02:03,200 --> 00:02:06,460 nasa has hired private companies to do the development 65 00:02:06,579 --> 00:02:08,540 and the operations in a new program 66 00:02:08,540 --> 00:02:10,259 called the commercial crew program 67 00:02:10,259 --> 00:02:12,539 the two companies that won the contracts are 68 00:02:12,539 --> 00:02:13,860 space and boeing 69 00:02:14,160 --> 00:02:15,468 I'm not really going to get into how 70 00:02:15,468 --> 00:02:17,588 the commercial crew program got started or 71 00:02:17,588 --> 00:02:19,091 has progressed in today's video 72 00:02:19,348 --> 00:02:21,611 I mostly want to talk about the hardware 73 00:02:21,628 --> 00:02:23,891 starting off with bowing and their starling 74 00:02:24,090 --> 00:02:24,727 boeing started 75 00:02:24,727 --> 00:02:25,652 designing the star liner 76 00:02:25,652 --> 00:02:27,892 originally known as the cst 100 77 00:02:27,927 --> 00:02:30,727 in 2010 after winning a contract from nasa 78 00:02:30,727 --> 00:02:32,127 for the cc dev program 79 00:02:32,127 --> 00:02:33,670 the starling is a traditional 80 00:02:33,670 --> 00:02:35,487 truncated cone capsule design 81 00:02:35,487 --> 00:02:38,052 much like previous spacecraft from the United States 82 00:02:38,310 --> 00:02:40,622 it can carry up to seven astronauts at a time 83 00:02:40,997 --> 00:02:43,742 although nasa won't use more than four seats at a time 84 00:02:43,917 --> 00:02:45,222 the starling will be the first 85 00:02:45,397 --> 00:02:47,822 orbital capsule to land on solid ground 86 00:02:47,837 --> 00:02:48,982 in the United States 87 00:02:49,140 --> 00:02:51,456 now this is similar to how this soyuz capsule land 88 00:02:51,623 --> 00:02:53,496 and also how blue origin 89 00:02:53,503 --> 00:02:55,903 sub orbital new shepherd capsule lands 90 00:02:55,903 --> 00:02:56,656 there are five 91 00:02:56,703 --> 00:02:59,080 landing sites proposed in the western United States 92 00:02:59,080 --> 00:03:01,543 but the two prime sites will be the us's army 93 00:03:01,543 --> 00:03:03,816 white sands missile range in new Mexico 94 00:03:03,990 --> 00:03:06,685 and the army's doggy proving grounds in Utah 95 00:03:06,685 --> 00:03:07,605 starr will land 96 00:03:07,605 --> 00:03:09,974 using parachutes and a set of large airbags 97 00:03:10,125 --> 00:03:12,370 a pair of drug shoots are deployed at about 9 98 00:03:12,370 --> 00:03:13,534 kilometers and altitude 99 00:03:13,645 --> 00:03:17,294 followed by a trio of main shoots at 3.6 kilometers 100 00:03:17,365 --> 00:03:19,187 and at 1.5 kilometers in altitude 101 00:03:19,187 --> 00:03:20,245 the heat shield is ditch 102 00:03:20,245 --> 00:03:22,214 and the six airbags are inflated 103 00:03:24,288 --> 00:03:25,190 in nominal cases 104 00:03:25,190 --> 00:03:25,989 the airbags will 105 00:03:25,989 --> 00:03:27,870 soften the landing when landing on land 106 00:03:28,149 --> 00:03:29,669 and in awful nominal cases 107 00:03:29,669 --> 00:03:31,830 like an abort or an emergency re entry 108 00:03:31,949 --> 00:03:34,789 the airbags offer buoyancy and balance for water 109 00:03:34,789 --> 00:03:36,658 landings touching down on land 110 00:03:36,658 --> 00:03:37,689 will allow the starling 111 00:03:37,689 --> 00:03:40,341 or an easy path to refurbishment and reusability 112 00:03:40,458 --> 00:03:42,618 boeing is hoping to be able to turn one around in just 113 00:03:42,618 --> 00:03:46,341 six months and reuse them up to 10 times 114 00:03:46,680 --> 00:03:48,730 that's definitely a good thing 115 00:03:48,870 --> 00:03:51,130 since the crew will land on solid ground 116 00:03:51,310 --> 00:03:54,530 recovery of crew is quite different than a splashdown 117 00:03:54,670 --> 00:03:55,910 on the edge of the landing zone 118 00:03:55,910 --> 00:03:59,570 there'll be a mobile data tracking vehicle or mdt 119 00:03:59,970 --> 00:04:03,107 as well as a mobile landing control center or mlc 120 00:04:03,192 --> 00:04:05,392 and a host of other recovery vehicles 121 00:04:05,392 --> 00:04:06,352 waiting to pounds 122 00:04:06,352 --> 00:04:08,027 once touchdown is confirmed 123 00:04:08,032 --> 00:04:08,672 a small 124 00:04:08,672 --> 00:04:11,787 army of vehicles will race their way across the desert 125 00:04:11,792 --> 00:04:14,472 now I picture this pretty much being like a real life 126 00:04:14,472 --> 00:04:15,947 mad max scenario 127 00:04:16,310 --> 00:04:18,650 boeing please send us videos of this 128 00:04:18,770 --> 00:04:20,450 upon arrival a crew will check 129 00:04:20,450 --> 00:04:22,030 and stabilize the hydrogen fuels 130 00:04:22,030 --> 00:04:24,370 and then ground the vehicle for static electricity 131 00:04:24,770 --> 00:04:27,330 after that an hvac truck will roll up 132 00:04:27,370 --> 00:04:28,850 and start to cool the spacecraft 133 00:04:28,850 --> 00:04:30,610 including the crew and the fuels 134 00:04:30,650 --> 00:04:33,250 next up a mobile landing platform will pull up with 135 00:04:33,250 --> 00:04:35,330 stairs and begin to evacuate the crew 136 00:04:35,670 --> 00:04:37,831 boeing has to pull crew out within 1h 137 00:04:37,831 --> 00:04:38,511 and cargo out 138 00:04:38,511 --> 00:04:40,068 within two the person who 139 00:04:40,111 --> 00:04:41,548 actually extracts the crew 140 00:04:41,551 --> 00:04:44,028 is a member of boeing's fire and rescue team 141 00:04:44,271 --> 00:04:45,591 which I think is pretty cool 142 00:04:45,591 --> 00:04:46,511 the crew is taken out 143 00:04:46,511 --> 00:04:48,031 and then set over to a truck for medical 144 00:04:48,031 --> 00:04:51,068 checkups and then whisked away on a nasa helicopter 145 00:04:51,390 --> 00:04:53,765 eventually the capsule itself will be loaded up with a 146 00:04:53,765 --> 00:04:54,754 small crane truck 147 00:04:54,845 --> 00:04:56,685 and taken back to begin refurbishment 148 00:04:56,685 --> 00:04:58,485 the cockpit of starling takes a 149 00:04:58,485 --> 00:05:00,634 fairly conservative and familiar approach 150 00:05:00,930 --> 00:05:02,230 although it's a lot 151 00:05:02,230 --> 00:05:04,865 less clutter than the space shuttles cockpit 152 00:05:04,865 --> 00:05:07,714 it still features familiar and traditional controls 153 00:05:07,745 --> 00:05:09,914 buttons and non touch screens 154 00:05:09,945 --> 00:05:12,794 the starling will dock to the iss and not birth 155 00:05:13,020 --> 00:05:14,155 docking is where the vehicle 156 00:05:14,165 --> 00:05:16,195 actually does all the final maneuvering 157 00:05:16,405 --> 00:05:18,355 until it connects itself up with the docking port 158 00:05:18,405 --> 00:05:20,639 dragon 1 and sign car of vehicles 159 00:05:20,639 --> 00:05:22,880 both currently birth to the station 160 00:05:22,919 --> 00:05:24,959 meaning they park and then are grappled to the station 161 00:05:24,959 --> 00:05:25,999 via the Canada arm 162 00:05:25,999 --> 00:05:27,199 or Canada arm 163 00:05:27,199 --> 00:05:29,399 astronauts get in and out of the side 164 00:05:29,399 --> 00:05:30,360 hatched room on earth 165 00:05:30,360 --> 00:05:32,559 but when doctor they'll crawl through the top part 166 00:05:32,559 --> 00:05:34,440 that connects to the international space station 167 00:05:34,719 --> 00:05:37,560 via the international docking adapter on the iss 168 00:05:37,800 --> 00:05:38,773 initially getting 169 00:05:38,826 --> 00:05:40,506 into and out of the starling is 170 00:05:40,506 --> 00:05:42,413 admittedly a bit cumbersome 171 00:05:42,666 --> 00:05:44,620 astronauts need to shimmy into their seats 172 00:05:44,620 --> 00:05:45,853 lying on their backs 173 00:05:45,990 --> 00:05:48,096 the spacecraft is two main sections 174 00:05:48,096 --> 00:05:50,283 the crew module and the service module 175 00:05:50,376 --> 00:05:51,763 the crew module is 176 00:05:52,376 --> 00:05:53,883 well exactly what you'd think 177 00:05:54,096 --> 00:05:55,256 so where the crew goes 178 00:05:55,256 --> 00:05:57,563 it's also the part that survives reentry 179 00:05:57,720 --> 00:05:59,660 the service module houses propellant tanks 180 00:05:59,660 --> 00:06:00,835 for orbital maneuvering 181 00:06:00,925 --> 00:06:02,565 the orbital maneuvering thrusters 182 00:06:02,565 --> 00:06:03,765 the launch of board motors 183 00:06:03,765 --> 00:06:06,435 which are on the bottom and a pusher configuration 184 00:06:06,725 --> 00:06:10,315 solar panels on the bottom and radiators on the sides 185 00:06:10,410 --> 00:06:11,763 as well as a host of other things 186 00:06:11,856 --> 00:06:13,283 the abort motors are for 187 00:06:13,336 --> 00:06:14,510 aero jet rocketry 188 00:06:14,510 --> 00:06:18,483 rs88 bantams modified to run on hyperbolic fuels 189 00:06:18,576 --> 00:06:20,563 to function as a launch abort motor 190 00:06:20,880 --> 00:06:23,285 the first uncured test flight oft1 191 00:06:23,474 --> 00:06:25,845 will fly with the qualification test motors 192 00:06:25,914 --> 00:06:27,234 but they'll be inactive 193 00:06:27,234 --> 00:06:28,845 since there will be no crew on board 194 00:06:28,874 --> 00:06:30,914 in the event of an issue with the booster or 195 00:06:30,914 --> 00:06:32,845 a rapid unscheduled disassembly 196 00:06:33,234 --> 00:06:35,114 these abort motors would be used up 197 00:06:35,114 --> 00:06:36,685 until a few minutes into flight 198 00:06:36,994 --> 00:06:38,394 after which time the vehicle would just use 199 00:06:38,394 --> 00:06:39,605 the maneuvering thrusters 200 00:06:39,870 --> 00:06:42,703 the starling offers a full envelope of board window 201 00:06:42,703 --> 00:06:44,943 meaning the astronauts can abort at any time 202 00:06:44,943 --> 00:06:46,037 and remain safe 203 00:06:46,063 --> 00:06:46,980 boeing design the 204 00:06:46,980 --> 00:06:49,240 starer to be able to ride on a variety of rockets 205 00:06:49,240 --> 00:06:50,614 including the atlas 5 206 00:06:50,905 --> 00:06:52,974 the delta 4 and the falcon 9 207 00:06:53,145 --> 00:06:54,945 they wand up selecting united launch alliances 208 00:06:54,945 --> 00:06:56,134 atlas 5 for now 209 00:06:56,185 --> 00:06:57,425 and eventually ula's 210 00:06:57,425 --> 00:06:59,945 upcoming vulcan rocket will likely fly starling 211 00:06:59,945 --> 00:07:02,734 the exact atlas 5 they selected isn't n22 212 00:07:02,905 --> 00:07:04,585 now here's a quick reminder of those numbers 213 00:07:04,585 --> 00:07:07,094 the first part of the name represents the fairing 214 00:07:07,280 --> 00:07:11,440 the options being four meters five meters or n for none 215 00:07:11,720 --> 00:07:12,400 the middle number 216 00:07:12,400 --> 00:07:13,600 is the amount of strap on 217 00:07:13,600 --> 00:07:16,462 rocket boosters and can range from 0 to 5 218 00:07:16,697 --> 00:07:17,417 the last number 219 00:07:17,417 --> 00:07:18,057 is the number 220 00:07:18,057 --> 00:07:20,982 of arl 10 engines on the centaur upper stage 221 00:07:21,097 --> 00:07:24,177 the centaur can have one or two rl10s 222 00:07:24,177 --> 00:07:25,217 so putting this all together 223 00:07:25,217 --> 00:07:26,057 the atlas 5 224 00:07:26,057 --> 00:07:28,257 that will launch the starling will have no fairing 225 00:07:28,257 --> 00:07:29,618 since it has a starling 226 00:07:29,618 --> 00:07:32,430 on top it'll have two solid rocket boosters 227 00:07:32,430 --> 00:07:35,510 and dual arl 10 engines on the upper stage 228 00:07:35,550 --> 00:07:37,470 hence the n22 229 00:07:37,590 --> 00:07:40,030 when the starling launches it'll be the first time 230 00:07:40,030 --> 00:07:42,030 ula's actually used a dual 231 00:07:42,030 --> 00:07:44,881 rl 10 centaur upper stage on the atlas 5 232 00:07:45,018 --> 00:07:45,470 however 233 00:07:45,470 --> 00:07:48,721 the dual engine centaur has been flying since 1962 234 00:07:48,978 --> 00:07:51,761 and flew on the atlas 3 is recently as 2005 235 00:07:52,098 --> 00:07:54,401 so it's definitely not anything new 236 00:07:54,538 --> 00:07:58,201 so why are boeing and ula using a dual engine centaur 237 00:07:58,298 --> 00:08:00,321 when the starling is relatively light 238 00:08:00,720 --> 00:08:03,333 the rl 10 engine is crazy efficient 239 00:08:03,506 --> 00:08:05,013 but one thing it's not 240 00:08:05,466 --> 00:08:07,826 is powerful in order to allow for enough time 241 00:08:07,826 --> 00:08:10,186 for a standard single engine to push the upper stage 242 00:08:10,186 --> 00:08:12,330 and its payload into orbital velocities 243 00:08:12,689 --> 00:08:14,210 without re entering the atmosphere 244 00:08:14,329 --> 00:08:15,769 the first stage of the atlas 5 245 00:08:15,769 --> 00:08:18,530 usually lost itself into an extra high altitude 246 00:08:18,609 --> 00:08:19,649 allowing for more time 247 00:08:19,649 --> 00:08:21,929 for the upper stage to do its secularization burn 248 00:08:21,929 --> 00:08:23,929 this works great for standard payloads 249 00:08:23,929 --> 00:08:25,250 but in the case of an abort 250 00:08:25,530 --> 00:08:27,843 trajectory is actually way too steep 251 00:08:27,843 --> 00:08:29,416 generating crazy high 252 00:08:29,483 --> 00:08:32,083 unsurvivable g forces when it hits the atmosphere 253 00:08:32,083 --> 00:08:33,656 so in order to maintain a nice 254 00:08:33,723 --> 00:08:34,950 safe shallow profile 255 00:08:34,950 --> 00:08:37,096 for the fragile and precious humans on board 256 00:08:37,123 --> 00:08:39,016 the upper stage needed more pomp 257 00:08:39,299 --> 00:08:41,892 and the solution to that was the dual engine centaur 258 00:08:42,145 --> 00:08:42,585 if you need 259 00:08:42,585 --> 00:08:44,466 more info on this unique engineering solution 260 00:08:44,466 --> 00:08:46,346 scott mainly has an awesome video on it 261 00:08:46,346 --> 00:08:47,426 boeing and ula will 262 00:08:47,426 --> 00:08:49,773 also be running a secondary flight computer 263 00:08:49,786 --> 00:08:50,586 they'll be running in 264 00:08:50,586 --> 00:08:51,346 parallel to the 265 00:08:51,346 --> 00:08:53,813 primary flight computer on the centaur upper stage 266 00:08:54,000 --> 00:08:56,072 it'll catch any errors in the flight plan 267 00:08:56,207 --> 00:08:57,872 faster than a human reaction time 268 00:08:58,180 --> 00:09:00,392 shutting down the engines and triggering an abort 269 00:09:00,447 --> 00:09:01,047 another design 270 00:09:01,047 --> 00:09:01,807 consideration is 271 00:09:01,807 --> 00:09:04,032 due to the blunt nose of the starling 272 00:09:04,167 --> 00:09:05,032 you'll see these little 273 00:09:05,047 --> 00:09:06,552 lattice structures around the outside 274 00:09:07,080 --> 00:09:07,957 the starling was 275 00:09:07,957 --> 00:09:10,402 designed to be as stable as possible for re entry 276 00:09:10,477 --> 00:09:13,122 which means having a short and stout design 277 00:09:13,277 --> 00:09:15,280 the lattice structure helps to fuse the airflow 278 00:09:15,280 --> 00:09:16,042 over the vehicle 279 00:09:16,117 --> 00:09:18,197 helping to make sure there are no shockwaves or 280 00:09:18,197 --> 00:09:19,597 inadvertent pressure areas 281 00:09:19,597 --> 00:09:22,042 over the lower portion of the vehicle on a scent 282 00:09:22,530 --> 00:09:24,866 especially since the rocket actually tapers down 283 00:09:24,866 --> 00:09:26,673 to the skinny centaur upper stage 284 00:09:26,906 --> 00:09:28,986 they also added an aerodynamic skirt 285 00:09:28,986 --> 00:09:30,786 to ensure smooth airflow 286 00:09:30,786 --> 00:09:33,706 despite the apollo spacecraft being a similar shape 287 00:09:33,706 --> 00:09:35,633 the saturn 5 a road on top of 288 00:09:35,666 --> 00:09:37,473 kind of wedding caked out 289 00:09:37,546 --> 00:09:39,106 tapering wider and wider 290 00:09:39,106 --> 00:09:41,833 and therefore didn't have those design considerations 291 00:09:41,880 --> 00:09:44,700 starer astronauts will take off from ula's launchpad 292 00:09:44,700 --> 00:09:48,515 sc 41 at cape canaveral air force station in Florida 293 00:09:48,900 --> 00:09:49,612 the pad has already 294 00:09:49,612 --> 00:09:51,240 been fitted with the crew access arm 295 00:09:51,240 --> 00:09:52,572 in preparations for the first 296 00:09:52,572 --> 00:09:53,572 crew launches 297 00:09:53,572 --> 00:09:54,972 this will be the first time 298 00:09:54,972 --> 00:09:57,452 humans have launched from this particular launch pad 299 00:09:57,452 --> 00:09:58,787 which is awesome and 300 00:09:58,812 --> 00:09:59,652 also the first time 301 00:09:59,652 --> 00:10:00,692 humans have launched from 302 00:10:00,692 --> 00:10:02,547 cape canaveral air force station 303 00:10:02,652 --> 00:10:05,267 since apollo 7 in 1968 304 00:10:05,610 --> 00:10:07,363 we'll get into the dimensions the designs 305 00:10:07,363 --> 00:10:08,616 prices and more 306 00:10:08,643 --> 00:10:10,443 when we do a side by side comparison 307 00:10:10,443 --> 00:10:11,376 of all the vehicles 308 00:10:16,392 --> 00:10:18,236 now on to the other new spaceship 309 00:10:18,236 --> 00:10:21,161 spacex's crew dragon or dragon 2 dragon 310 00:10:21,161 --> 00:10:23,113 2 is the follow up to spacex's 311 00:10:23,113 --> 00:10:26,033 very successful dragon capsule that has flown cargo to 312 00:10:26,033 --> 00:10:27,313 and from the iss 313 00:10:27,313 --> 00:10:28,226 since 2012 314 00:10:28,233 --> 00:10:30,570 the dragon capsule was originally called dragon writer 315 00:10:30,570 --> 00:10:32,793 when it was initially proposed to nasa for the cc 316 00:10:32,793 --> 00:10:33,666 dev program 317 00:10:33,900 --> 00:10:36,235 space was not selected for the first round 318 00:10:36,520 --> 00:10:39,004 perhaps because the dragon capsule had noses 319 00:10:39,004 --> 00:10:39,724 all around it 320 00:10:39,724 --> 00:10:42,040 but spacex was selected during the second 321 00:10:42,040 --> 00:10:43,050 round of contracts 322 00:10:43,050 --> 00:10:45,130 the original dragon writer capsule was essentially 323 00:10:45,130 --> 00:10:47,810 just a cru rated version of their dragon capsule 324 00:10:47,850 --> 00:10:49,930 which at the time was getting ready for its 1st 325 00:10:49,930 --> 00:10:51,290 test flights to orbit 326 00:10:51,410 --> 00:10:54,050 and was already on contract to resupply the iss 327 00:10:54,210 --> 00:10:55,770 which would later due in 2012 328 00:10:55,930 --> 00:10:58,590 in 2014 spacex revealed the updated 329 00:10:58,590 --> 00:10:59,890 version of the dragon capsule 330 00:10:59,930 --> 00:11:00,290 which would 331 00:11:00,290 --> 00:11:02,890 carry astronauts at their headquarters in hawthorne 332 00:11:03,000 --> 00:11:03,682 the dragon 2 333 00:11:03,682 --> 00:11:06,637 was a massive redesign of the original dragon capsule 334 00:11:06,642 --> 00:11:09,317 including seating for up to seven astronauts 335 00:11:09,362 --> 00:11:10,357 although again 336 00:11:10,482 --> 00:11:12,762 nasa won't be using more than four at a time 337 00:11:12,762 --> 00:11:14,042 for the commercial crew program 338 00:11:14,042 --> 00:11:15,797 dragon 2 was originally planning to 339 00:11:15,802 --> 00:11:18,557 also touchdown back on land using the abort motors 340 00:11:18,690 --> 00:11:20,611 assuming they weren't used for an abort 341 00:11:20,688 --> 00:11:23,171 to come to a nice soft touchdown anywhere 342 00:11:23,368 --> 00:11:25,488 however due to a few reasons 343 00:11:25,488 --> 00:11:27,288 space ditch propulsive landings 344 00:11:27,288 --> 00:11:27,928 and will do a 345 00:11:27,928 --> 00:11:30,211 parachute recovery and splashdown in the ocean 346 00:11:30,368 --> 00:11:32,128 much like the current dragon capsule 347 00:11:32,128 --> 00:11:33,408 if you need to know more about why 348 00:11:33,408 --> 00:11:34,230 space canceled 349 00:11:34,230 --> 00:11:36,091 propulsive landing their dragon capsule 350 00:11:36,540 --> 00:11:37,860 I've already got you covered the crew 351 00:11:37,860 --> 00:11:40,580 dragon's primary landing zone is the Atlantic Ocean 352 00:11:40,580 --> 00:11:42,840 which is different from the current dragon capsule 353 00:11:42,840 --> 00:11:44,900 which has been splashing down in the Pacific Ocean 354 00:11:44,900 --> 00:11:47,020 since its first launch and recovery in 2010 355 00:11:47,100 --> 00:11:49,460 space also filed to have the gulf of Mexico 356 00:11:49,460 --> 00:11:51,300 be a contingency landing site too 357 00:11:51,620 --> 00:11:53,740 which I believe would be at first 358 00:11:54,150 --> 00:11:55,957 space has a pair of ships named go 359 00:11:55,957 --> 00:11:57,342 searcher and go navigator 360 00:11:57,357 --> 00:11:59,182 that'll be in charge of crew recoveries 361 00:11:59,437 --> 00:12:00,917 go searcher features a hoist 362 00:12:00,917 --> 00:12:03,222 capable of lifting the dragon capsule onto the deck 363 00:12:03,510 --> 00:12:04,763 and then offloading the crew 364 00:12:04,763 --> 00:12:05,537 there's communication 365 00:12:05,537 --> 00:12:05,970 relays 366 00:12:05,970 --> 00:12:08,363 and a helicopter landing pad to get the crew home 367 00:12:08,363 --> 00:12:09,403 after splashdown go 368 00:12:09,403 --> 00:12:11,497 searcher has been part of spacex's fleet for a while 369 00:12:11,810 --> 00:12:13,206 80 in the recovery efforts of falcon 370 00:12:13,206 --> 00:12:14,377 9 transship landings 371 00:12:14,403 --> 00:12:16,257 as well as dragon 1 recoveries 372 00:12:16,560 --> 00:12:17,551 despite the ocean landing 373 00:12:17,551 --> 00:12:18,071 space 374 00:12:18,071 --> 00:12:20,808 does have refurbishment and reuse plans for dragon 2 375 00:12:21,031 --> 00:12:23,328 although not quite like you might be thinking 376 00:12:23,431 --> 00:12:25,848 refurbished dragon 2's won't carry humans again 377 00:12:26,031 --> 00:12:27,791 but they'll eventually be used to carry 378 00:12:27,791 --> 00:12:29,608 cargo for crs2 missions 379 00:12:29,631 --> 00:12:31,151 space already has experience 380 00:12:31,151 --> 00:12:33,168 refurbishing splashdown dragon capsules 381 00:12:33,391 --> 00:12:35,968 and has flown five dragon capsules to date 382 00:12:36,300 --> 00:12:38,334 although according to elon mosque in 2017 383 00:12:38,745 --> 00:12:40,120 he mentions it's almost as 384 00:12:40,120 --> 00:12:42,574 expensive to refurbish the splash down dragons 385 00:12:42,665 --> 00:12:44,145 as it is to build new ones 386 00:12:44,145 --> 00:12:44,625 but I'm sure 387 00:12:44,625 --> 00:12:47,294 since then they've implemented streamlined processes 388 00:12:47,465 --> 00:12:49,145 which have helped made the efforts worthwhile 389 00:12:49,145 --> 00:12:50,134 the design of the crew 390 00:12:50,134 --> 00:12:52,934 dragon capsule is extremely minimalistic 391 00:12:53,190 --> 00:12:55,700 it's easy to see that the design was influenced by elon 392 00:12:55,700 --> 00:12:57,159 who likes things simple 393 00:12:57,220 --> 00:12:59,420 the interior looks like the tesla model 3 of 394 00:12:59,420 --> 00:13:00,719 spaceships compared to 395 00:13:00,730 --> 00:13:02,340 night riders car kit 396 00:13:02,340 --> 00:13:04,940 some unique features of the interior are touch screens 397 00:13:04,940 --> 00:13:06,439 and movable chairs 398 00:13:06,720 --> 00:13:08,396 when dragon 2 was first revealed 399 00:13:08,500 --> 00:13:10,996 elon satin a seat and pulled the screen down to him 400 00:13:11,203 --> 00:13:12,203 that's now reversed 401 00:13:12,203 --> 00:13:14,723 as the screens are stationary and the seats move up 402 00:13:14,723 --> 00:13:15,796 to them again 403 00:13:15,963 --> 00:13:17,020 just like the starling 404 00:13:17,020 --> 00:13:19,733 the dragon 2 is designed to be fully autonomous 405 00:13:19,733 --> 00:13:21,253 with manual overrides really 406 00:13:21,253 --> 00:13:22,966 only there as contingencies 407 00:13:23,253 --> 00:13:25,613 but the dragon 2 does something that the old dragon one 408 00:13:25,613 --> 00:13:27,686 couldn't do and that's dock 409 00:13:27,693 --> 00:13:29,133 getting into the dragon capsules 410 00:13:29,133 --> 00:13:30,526 done via the side hatch 411 00:13:30,613 --> 00:13:31,693 once you poke your head in 412 00:13:31,693 --> 00:13:33,966 it's very spacious and minimalistic 413 00:13:34,093 --> 00:13:36,526 it's easy to plop into the seat and get comfy 414 00:13:36,960 --> 00:13:39,230 I actually really think this layout makes sense 415 00:13:39,230 --> 00:13:40,105 like the starling 416 00:13:40,105 --> 00:13:42,489 the dragon 2 is actually two sections as well 417 00:13:42,710 --> 00:13:44,649 there's the crew module and the trunk 418 00:13:44,750 --> 00:13:47,569 the crew module is again the part that holds the humans 419 00:13:47,710 --> 00:13:48,670 but it also has 420 00:13:48,670 --> 00:13:51,529 the super draco abort motors integrated onto it 421 00:13:51,870 --> 00:13:54,209 since this portion of the spacecraft is recovered 422 00:13:54,270 --> 00:13:56,609 the super draco motors are also recovered 423 00:13:56,940 --> 00:13:58,960 you just like the starling 424 00:13:58,960 --> 00:14:01,133 the super draco's run on hyperbolic propellants 425 00:14:01,186 --> 00:14:04,013 and offer a full envelope abort window as well 426 00:14:04,106 --> 00:14:07,026 the trunk is an unpressurized section of the spacecraft 427 00:14:07,026 --> 00:14:08,573 just like it is on dragon 1 428 00:14:08,706 --> 00:14:10,146 this allows for the ability to take up 429 00:14:10,146 --> 00:14:11,106 larger components that 430 00:14:11,106 --> 00:14:12,613 wouldn't fit through the docking port 431 00:14:12,866 --> 00:14:13,146 or 432 00:14:13,146 --> 00:14:15,693 items that are installed on the outside of the station 433 00:14:15,786 --> 00:14:16,440 items that are in 434 00:14:16,440 --> 00:14:18,686 inside the trunk are retrieved via the Canada arm 435 00:14:18,686 --> 00:14:21,072 2 or another arm named dexter 436 00:14:21,072 --> 00:14:22,026 the trunk of the dragon 437 00:14:22,026 --> 00:14:24,820 2 offers a unique layout with stationary solar panels 438 00:14:24,820 --> 00:14:26,247 covering one side of the vehicle 439 00:14:26,352 --> 00:14:27,300 and radiators 440 00:14:27,300 --> 00:14:28,247 on the other side 441 00:14:28,552 --> 00:14:31,407 the old dragon 1 had extending solar panels 442 00:14:31,530 --> 00:14:32,203 this makes sense 443 00:14:32,203 --> 00:14:34,417 because you want the solar panels to be facing the sun 444 00:14:34,563 --> 00:14:36,777 and you want the radiators away from the sun 445 00:14:36,923 --> 00:14:37,297 so 446 00:14:38,043 --> 00:14:38,937 pretty cool design 447 00:14:38,963 --> 00:14:40,923 the trunk also has some fins to help 448 00:14:40,923 --> 00:14:42,977 stabilize the vehicle in the event of an abort 449 00:14:43,261 --> 00:14:44,995 again I already did a video all about this 450 00:14:44,995 --> 00:14:45,915 so if you want to learn more 451 00:14:45,915 --> 00:14:47,384 about the fins on the dragon 452 00:14:47,435 --> 00:14:49,144 and why they matter during an abort 453 00:14:49,195 --> 00:14:50,184 check out this video 454 00:14:50,235 --> 00:14:53,075 the trunk is detached prior to reentry and burns up 455 00:14:53,075 --> 00:14:54,504 due to a lack of a heat shield 456 00:14:54,750 --> 00:14:56,188 this allows for disposal of some 457 00:14:56,188 --> 00:14:57,511 on station items as well 458 00:14:58,188 --> 00:15:00,628 very fiery garbage service 459 00:15:00,628 --> 00:15:01,099 the dragon 460 00:15:01,099 --> 00:15:03,706 2 is designed to exclusively fly in the falcon 9 461 00:15:03,893 --> 00:15:04,693 although there were 462 00:15:04,693 --> 00:15:06,826 plans for it to fly in a falcon heavy at one point 463 00:15:06,933 --> 00:15:07,266 but 464 00:15:07,333 --> 00:15:09,820 space no longer plans to human certify falcon heavy 465 00:15:09,820 --> 00:15:11,773 and instead is focusing on starship 466 00:15:11,773 --> 00:15:13,706 in order for the falcon 9 to be crew rated 467 00:15:13,900 --> 00:15:14,946 nasa required a 468 00:15:14,973 --> 00:15:16,556 design freeze of their block 5 variants 469 00:15:16,556 --> 00:15:18,493 and spacex tends to upgrade their vehicles 470 00:15:18,493 --> 00:15:19,426 so frequently 471 00:15:20,354 --> 00:15:23,207 sometimes introduce unintended consequences 472 00:15:23,412 --> 00:15:24,567 part of the design freeze 473 00:15:24,572 --> 00:15:26,452 also required the use of a new composite 474 00:15:26,452 --> 00:15:27,532 overrated pressure vessel 475 00:15:27,532 --> 00:15:28,607 or cop 476 00:15:28,892 --> 00:15:31,221 the co failure was the root cause of the amo 477 00:15:31,221 --> 00:15:32,327 6 pad anomaly 478 00:15:32,492 --> 00:15:36,007 and a cop strut was the cause of the crs 7 failure 479 00:15:36,300 --> 00:15:38,781 space started flying a newly designed cop 480 00:15:38,781 --> 00:15:40,018 at the end of 2018 481 00:15:40,221 --> 00:15:43,181 it's kind of unusual that nasa required a design freeze 482 00:15:43,181 --> 00:15:43,501 I mean 483 00:15:43,501 --> 00:15:45,781 considering nasa has considered flying humans on the 484 00:15:45,781 --> 00:15:47,338 2nd launch of sls 485 00:15:47,790 --> 00:15:48,970 or even more crazy 486 00:15:48,970 --> 00:15:50,169 there's even been talks of them 487 00:15:50,169 --> 00:15:51,610 putting humans on the 1st 488 00:15:51,610 --> 00:15:52,729 flight of sls 489 00:15:52,770 --> 00:15:55,809 but spacex is known to make changes all the time 490 00:15:55,970 --> 00:15:58,089 in the constant pursuit of improvement 491 00:15:58,602 --> 00:16:00,146 so I think a safer 492 00:16:00,146 --> 00:16:02,466 more conservative approach is a good idea 493 00:16:02,466 --> 00:16:04,066 when human lives are involved 494 00:16:04,066 --> 00:16:06,113 the falcon 9's flight profile with the crew 495 00:16:06,226 --> 00:16:08,666 also had to be altered compared to the cargo versions 496 00:16:08,666 --> 00:16:11,473 to ensure the safest profile and case of an abort 497 00:16:11,706 --> 00:16:13,786 due to the shallower flatter profile 498 00:16:13,786 --> 00:16:15,570 it also means the first age booster 499 00:16:15,570 --> 00:16:18,673 the falcon 9 will not do a return to launch si landing 500 00:16:18,787 --> 00:16:21,123 and we'll have to land down range on the drone ship 501 00:16:21,123 --> 00:16:22,131 the upper stage of the falcon 502 00:16:22,131 --> 00:16:24,283 9 uses the merlin 1d vacuum engine 503 00:16:24,283 --> 00:16:26,356 which is extremely powerful 504 00:16:26,820 --> 00:16:28,143 but not very efficient 505 00:16:28,216 --> 00:16:29,623 it will have no problem 506 00:16:29,696 --> 00:16:31,336 maintaining a shallow profile 507 00:16:31,336 --> 00:16:33,128 crew will climb on top of a block 508 00:16:33,128 --> 00:16:34,136 5 falcon 9 509 00:16:34,136 --> 00:16:35,440 poise at launch complex 510 00:16:35,440 --> 00:16:37,663 39a at kennedy space center in Florida 511 00:16:37,776 --> 00:16:39,816 now I have to say not that it's a contest 512 00:16:39,816 --> 00:16:42,640 but spacex definitely does have the coolest launch pad 513 00:16:42,640 --> 00:16:44,025 ever mean after all 514 00:16:44,025 --> 00:16:46,465 this is the same launchpad that humans took off from 515 00:16:46,465 --> 00:16:47,534 to go to the moon 516 00:16:47,585 --> 00:16:49,374 crew will go up the fixed service structure 517 00:16:49,374 --> 00:16:51,254 that's a relic from the space shuttle era 518 00:16:51,425 --> 00:16:53,065 although spacex has done a lot of work 519 00:16:53,065 --> 00:16:54,974 to remove the rotating service structure 520 00:16:55,105 --> 00:16:56,214 repaint the tower 521 00:16:56,425 --> 00:16:59,534 add cladding and attach their mobile access arm 522 00:16:59,640 --> 00:17:01,533 one thing that spacex will be doing this 523 00:17:01,586 --> 00:17:04,133 completely new in the world of human spaceflight 524 00:17:04,186 --> 00:17:06,180 and actually took some convincing to make 525 00:17:06,180 --> 00:17:07,933 nasa consider a valid option 526 00:17:08,066 --> 00:17:10,573 is a load and go fueling procedure 527 00:17:10,586 --> 00:17:13,293 since spacex uses super chilled propellants 528 00:17:13,306 --> 00:17:14,980 they need to load them up into the vehicle as 529 00:17:14,980 --> 00:17:15,826 late as possible 530 00:17:15,826 --> 00:17:17,546 so they don't warm up and boil off 531 00:17:17,546 --> 00:17:18,853 before the vehicle takes off 532 00:17:19,230 --> 00:17:19,777 space 533 00:17:19,777 --> 00:17:22,002 actually continues to fuel the rocket up until just 534 00:17:22,017 --> 00:17:24,242 3min before liftoff now 535 00:17:24,242 --> 00:17:26,017 clearly 3min isn't nearly 536 00:17:26,017 --> 00:17:27,417 enough time to get up the tower 537 00:17:27,417 --> 00:17:29,210 and strap the crew into the dragon capsule 538 00:17:29,210 --> 00:17:30,500 and then leave the tower 539 00:17:30,639 --> 00:17:33,980 so the crew will actually enter before propellant load 540 00:17:34,039 --> 00:17:36,879 and will remain on board while the vehicles fueled up 541 00:17:36,879 --> 00:17:38,820 I can clearly understand how this is different 542 00:17:38,919 --> 00:17:41,599 but I actually feel like it's kind of a safer move 543 00:17:41,599 --> 00:17:43,900 I mean this means the astronauts and the ground crew 544 00:17:44,159 --> 00:17:44,479 never 545 00:17:44,479 --> 00:17:46,940 need to approach a fully loaded vehicle on the pad 546 00:17:46,980 --> 00:17:47,920 once fuel starts flowing 547 00:17:47,920 --> 00:17:50,429 the crew is actually in the safest place imaginable 548 00:17:50,450 --> 00:17:51,680 a tightly sealed 549 00:17:51,680 --> 00:17:54,469 pressure vessel armed with a powerful abort system 550 00:17:54,610 --> 00:17:58,029 so despite the process of fueling up being pretty risky 551 00:17:58,210 --> 00:18:00,189 the crew is in a very safe place 552 00:18:00,330 --> 00:18:01,309 can you imagine 553 00:18:01,710 --> 00:18:03,090 this will be the first time in history 554 00:18:03,090 --> 00:18:04,675 a human ear will hear the sound 555 00:18:04,675 --> 00:18:06,904 of cryogenic fuel flowing into the vehicle 556 00:18:07,075 --> 00:18:07,515 look here 557 00:18:07,515 --> 00:18:07,795 all 558 00:18:07,795 --> 00:18:09,955 those creeks and strains of the vehicle as it comes to 559 00:18:09,955 --> 00:18:10,304 life 560 00:18:11,262 --> 00:18:12,411 that's gonna be crazy 561 00:18:12,411 --> 00:18:13,200 another fun fact is 562 00:18:13,200 --> 00:18:15,651 the crew will arrive to the launch site in tesla model 563 00:18:15,651 --> 00:18:17,388 x's of course 564 00:18:17,971 --> 00:18:20,348 man spacex will be putting on a new show 565 00:18:20,531 --> 00:18:21,268 that's for sure 566 00:18:21,371 --> 00:18:23,988 now lastly before we get to the direct comparisons 567 00:18:24,211 --> 00:18:24,811 did you know 568 00:18:24,811 --> 00:18:27,148 both launchpads have an amusement park ride 569 00:18:27,660 --> 00:18:28,857 well not quite 570 00:18:28,857 --> 00:18:31,137 but each pad does have an emergency zip line 571 00:18:31,137 --> 00:18:33,320 capable of evacuating astronauts and ground crew 572 00:18:33,320 --> 00:18:35,942 in a hurry in the unlikely event of say 573 00:18:36,017 --> 00:18:37,297 a leak or a fire 574 00:18:37,297 --> 00:18:39,340 while I'm sure there's limited use cases one 575 00:18:39,340 --> 00:18:41,022 this would even be remotely useful 576 00:18:41,377 --> 00:18:42,942 it does look like it'd be pretty fun 577 00:18:43,500 --> 00:18:46,381 well assuming you're not being chased by a fireball 578 00:18:46,458 --> 00:18:49,098 oh okay wow enough of the rundown 579 00:18:49,098 --> 00:18:51,141 it's time to compare these vehicles side by side 580 00:18:51,338 --> 00:18:52,058 and see how these 581 00:18:52,058 --> 00:18:52,360 new 582 00:18:52,360 --> 00:18:54,981 vehicles compared to the soyuz and the space shuttle 583 00:18:59,423 --> 00:19:00,681 so first off 584 00:19:00,681 --> 00:19:03,081 let's just line these vehicles up side by side 585 00:19:03,081 --> 00:19:04,718 and compare their sizes 586 00:19:05,641 --> 00:19:06,361 yeah the 587 00:19:06,361 --> 00:19:08,140 space shuttle orbiter clearly 588 00:19:08,140 --> 00:19:09,958 dwarfs these vehicles in size 589 00:19:10,294 --> 00:19:12,467 that thing is huge 590 00:19:12,467 --> 00:19:14,147 and because of its immense size 591 00:19:14,147 --> 00:19:15,507 we're gonna focus in on just 592 00:19:15,507 --> 00:19:17,133 the crew module portion of the shuttle 593 00:19:17,133 --> 00:19:18,813 so we can see these other vehicles 594 00:19:19,027 --> 00:19:20,533 but don't forget about the rest of it 595 00:19:20,667 --> 00:19:22,693 we'll still be talking about the system as a whole 596 00:19:22,827 --> 00:19:23,067 since 597 00:19:23,067 --> 00:19:25,480 the aft end is its service module on the cargo bay 598 00:19:25,480 --> 00:19:26,360 is similar in nature 599 00:19:26,360 --> 00:19:27,973 to the trunk of the dragon capsule 600 00:19:28,830 --> 00:19:30,425 way way bigger 601 00:19:30,474 --> 00:19:31,194 but notice how much 602 00:19:31,194 --> 00:19:32,594 bigger the starling and dragon are 603 00:19:32,594 --> 00:19:33,754 compared to the soyuz 604 00:19:33,754 --> 00:19:35,114 so let's run through the dimension 605 00:19:35,114 --> 00:19:36,145 starting with their height 606 00:19:36,434 --> 00:19:38,194 the starling stands 5 meters tall 607 00:19:38,194 --> 00:19:39,745 with a service module attached 608 00:19:39,874 --> 00:19:41,554 the crew dragon is 8.1 609 00:19:41,554 --> 00:19:44,394 meters tall with the trunk and the soyuz is 7.5 610 00:19:44,394 --> 00:19:45,185 meters tall 611 00:19:45,314 --> 00:19:47,905 with the orbital module and service module attached 612 00:19:48,120 --> 00:19:50,596 the space shuttle will show its length as height 613 00:19:50,596 --> 00:19:52,924 because that's the way it stood when it was on the pad 614 00:19:53,036 --> 00:19:56,524 it stood 37 meters tall from tail to nose 615 00:19:56,636 --> 00:19:57,756 next they're width 616 00:19:57,756 --> 00:20:00,076 the starling is 4.5 meters wide 617 00:20:00,076 --> 00:20:02,324 the dragon capsule 3.7 meters wide 618 00:20:02,556 --> 00:20:05,004 the soyuz 2.2 meters and the space shuttles 619 00:20:05,004 --> 00:20:08,044 crew compartment and payload bay were 4.6 meters wide 620 00:20:08,432 --> 00:20:10,426 will ignore the wings for this comparison 621 00:20:10,426 --> 00:20:11,306 I feel like we're gonna have 622 00:20:11,306 --> 00:20:13,140 a lot of asterisks when we compare these 623 00:20:13,140 --> 00:20:14,266 vehicles to the space shuttle 624 00:20:14,266 --> 00:20:15,013 because that thing 625 00:20:15,186 --> 00:20:17,586 was a completely different beast 626 00:20:17,586 --> 00:20:19,813 next up dry mass starling is 13 627 00:20:19,866 --> 00:20:22,706 tons dragon is 9.5 tons 628 00:20:22,706 --> 00:20:26,413 the soyuz capsule is shockingly light at 7.1 tons 629 00:20:26,610 --> 00:20:27,450 and the space shuttle 630 00:20:27,610 --> 00:20:30,130 yeah you can imagine this is quite a bit heavier at 631 00:20:30,210 --> 00:20:32,970 68.5 tons as mentioned earlier 632 00:20:32,970 --> 00:20:35,650 crew capacity for both starling and dragon as 7 633 00:20:35,730 --> 00:20:37,410 but again nasa will only use four 634 00:20:38,010 --> 00:20:40,784 the soyuz capsule can fit three barely 635 00:20:41,035 --> 00:20:42,624 and the shuttle could fit up to eight 636 00:20:42,635 --> 00:20:45,915 although seven was much more common now for volume 637 00:20:45,915 --> 00:20:47,915 both pressurized and unpreciariz 638 00:20:47,915 --> 00:20:48,755 starr has 639 00:20:48,755 --> 00:20:51,230 11 cubic meters of pressurized volume and no one 640 00:20:51,230 --> 00:20:52,572 pressurized dragon 641 00:20:52,572 --> 00:20:55,424 2 has 10 cubic meters of pressurized volume and 14 642 00:20:55,475 --> 00:20:57,624 cubic meters of unpressurized volume 643 00:20:57,750 --> 00:20:58,450 soyuz has 644 00:20:58,450 --> 00:21:01,530 8.5 cubic meters of pressurized and no unpreceduri 645 00:21:01,530 --> 00:21:03,490 volume the space shuttle is of course 646 00:21:03,490 --> 00:21:04,233 king here with 647 00:21:04,266 --> 00:21:07,593 74.3 cubic meters from pressurized volume 648 00:21:07,626 --> 00:21:10,450 and 300 cubic meters of unpressurized 649 00:21:10,450 --> 00:21:12,058 volume in other words 650 00:21:12,221 --> 00:21:14,098 you could almost fit all three 651 00:21:14,141 --> 00:21:16,698 spaceships inside the payload bay of the shuttle 652 00:21:16,861 --> 00:21:19,738 so now how long can these vehicles stay in space 653 00:21:19,981 --> 00:21:21,098 the starlight can go 654 00:21:21,101 --> 00:21:24,618 60 hours on its own and 210 days while docked 655 00:21:24,840 --> 00:21:26,920 crew dragon can go one week on its own 656 00:21:26,920 --> 00:21:29,159 and also 210 days on doctor 657 00:21:29,240 --> 00:21:30,220 the soyuz can go 658 00:21:30,220 --> 00:21:33,039 30 days on its own and 180 days when doctor 659 00:21:33,120 --> 00:21:35,239 and the space shuttle couldn't go much beyond 17 660 00:21:35,320 --> 00:21:37,559 days due to being powered by fuel cells 661 00:21:37,830 --> 00:21:39,707 next up how about their abort systems 662 00:21:39,707 --> 00:21:42,347 the starling and crew dragon both have a pusher type 663 00:21:42,347 --> 00:21:43,050 system that's full 664 00:21:43,050 --> 00:21:43,792 envelope 665 00:21:43,907 --> 00:21:46,432 mean they can abort safely at any time during ascent 666 00:21:46,890 --> 00:21:48,745 the soyuz has a polar or a tractor 667 00:21:48,745 --> 00:21:50,025 system with an abort tower 668 00:21:50,025 --> 00:21:50,950 and ferry motors 2 669 00:21:50,950 --> 00:21:53,514 which also offers a full envelope escape 670 00:21:53,625 --> 00:21:54,225 and of course 671 00:21:54,225 --> 00:21:57,434 the space shuttle had no mechanical abort systems 672 00:21:57,570 --> 00:21:59,582 and a quick little note here on a board systems 673 00:21:59,678 --> 00:22:01,598 pushers push up from the bottom 674 00:22:01,598 --> 00:22:03,102 or the middle of the spacecraft 675 00:22:03,278 --> 00:22:05,398 and tractors or polar bore systems 676 00:22:05,398 --> 00:22:07,318 pull from the top using a tower 677 00:22:07,318 --> 00:22:08,158 or something like that 678 00:22:08,158 --> 00:22:09,742 now where to all these land 679 00:22:10,110 --> 00:22:13,607 starer shuttle and soyuz all touched down on land 680 00:22:13,772 --> 00:22:15,767 while crew dragons splashes down 681 00:22:15,852 --> 00:22:19,064 now how about reusability slash refurbishment ability 682 00:22:19,075 --> 00:22:21,864 the starlings capable of up to 10 reuses crew 683 00:22:21,864 --> 00:22:23,310 dragon is capable of reuse 684 00:22:23,310 --> 00:22:25,384 but for now only as cargo variant 685 00:22:25,515 --> 00:22:26,904 soyuz is expendable 686 00:22:27,075 --> 00:22:29,264 and the space shuttle was also reusable 687 00:22:29,395 --> 00:22:31,824 so now the launch vehicles that get these to space 688 00:22:32,310 --> 00:22:35,039 starr will ride the atlas 5 n22 689 00:22:35,260 --> 00:22:36,719 crew dragon the falcon 9 690 00:22:36,820 --> 00:22:40,039 soyuz the soyuz fg rocket and soon the soyuz 2 691 00:22:40,410 --> 00:22:42,491 and the shuttle was part of the space transportation 692 00:22:42,608 --> 00:22:44,328 system while we have these rockets pulled up 693 00:22:44,328 --> 00:22:45,190 I think it's important 694 00:22:45,190 --> 00:22:47,331 we take a note on their reliability 695 00:22:47,408 --> 00:22:48,919 we're going to ignore partial failures 696 00:22:48,919 --> 00:22:50,510 and only talk about mission success 697 00:22:50,510 --> 00:22:53,571 in which case the atlas 5 really comes up on top 698 00:22:53,688 --> 00:22:56,728 at 100 success in 79 flights 699 00:22:56,728 --> 00:22:57,771 the falcon 9 is at 700 00:22:57,808 --> 00:23:00,171 69 missions and has had two failures 701 00:23:00,420 --> 00:23:00,835 one of them 702 00:23:00,835 --> 00:23:02,804 actually happening before the launch occurred 703 00:23:02,835 --> 00:23:04,284 giving it a 97 704 00:23:04,517 --> 00:23:05,995 1 success rate 705 00:23:05,995 --> 00:23:07,635 the soyuz is complicated 706 00:23:07,635 --> 00:23:09,764 because it's been flying since the 60s 707 00:23:09,835 --> 00:23:10,875 in some form or another 708 00:23:10,875 --> 00:23:16,744 so in total it's 996 out of 1 000 28 for a 96 709 00:23:17,415 --> 00:23:20,944 9 success rate but its newest variant the fg 710 00:23:21,175 --> 00:23:23,455 has only had one failure out of 66 711 00:23:23,455 --> 00:23:25,944 making it 98 5 successful 712 00:23:26,015 --> 00:23:29,144 and the shuttle had two failures out of 135 launches 713 00:23:29,375 --> 00:23:31,655 also making it 98.5 successful 714 00:23:31,655 --> 00:23:33,775 it should also be noted that thanks to the abort 715 00:23:33,775 --> 00:23:36,092 system the 1 1 failure of the soyuz fg 716 00:23:36,340 --> 00:23:38,012 led to no loss in life 717 00:23:38,147 --> 00:23:39,187 and another quick note 718 00:23:39,187 --> 00:23:41,987 this time about the use of solid rocket boosters 719 00:23:41,987 --> 00:23:42,980 solid rocket booster 720 00:23:42,980 --> 00:23:45,012 led to the loss of the challenger vehicle 721 00:23:45,147 --> 00:23:47,347 but that's not to say solids on their own 722 00:23:47,347 --> 00:23:49,812 are inherently more dangerous per se 723 00:23:50,280 --> 00:23:50,950 the mixture of 724 00:23:50,950 --> 00:23:52,180 a solid rocket booster 725 00:23:52,180 --> 00:23:54,310 and the lack of a mechanical abort 726 00:23:54,310 --> 00:23:56,230 system is really what was dangerous 727 00:23:56,230 --> 00:23:57,070 we've learned a lot 728 00:23:57,070 --> 00:23:58,620 since the space shuttle and the atlas 729 00:23:58,620 --> 00:24:01,490 5's use of srb is considered very safe 730 00:24:01,981 --> 00:24:04,725 due to the fact that the starling does have an abort 731 00:24:04,725 --> 00:24:06,774 system if there was a failure 732 00:24:06,885 --> 00:24:08,854 the crew would be able to get away from the rocket 733 00:24:08,965 --> 00:24:12,454 so we really shouldn't compare the atlas's use of srs 734 00:24:12,525 --> 00:24:14,605 to the space shuttles use of srs 735 00:24:14,605 --> 00:24:16,694 and now where do all four of these launch from 736 00:24:16,765 --> 00:24:17,550 launch sites are 737 00:24:17,550 --> 00:24:19,710 slick 41 at cape canaveral air force base 738 00:24:19,710 --> 00:24:20,534 for starling 739 00:24:20,645 --> 00:24:22,552 right next door is the falcon 9 740 00:24:22,552 --> 00:24:25,828 which will launch from lc 39a at kennedy space center 741 00:24:25,872 --> 00:24:29,588 the soyuz launches from biker lc 1 5 742 00:24:30,240 --> 00:24:33,187 and the shuttle launch from both lc 39a and 743 00:24:33,187 --> 00:24:35,132 lc 39b at ksc 744 00:24:35,147 --> 00:24:37,480 and lastly we're gonna talk about price per seat 745 00:24:37,480 --> 00:24:40,012 and this one has a pretty big aster as well 746 00:24:40,187 --> 00:24:41,332 both starling and crew 747 00:24:41,332 --> 00:24:44,612 dragon have a price tag of 58 million per seat 748 00:24:44,910 --> 00:24:48,325 the soyuz capsule is now up to 82 million per seat 749 00:24:48,414 --> 00:24:49,245 and the shuttle 750 00:24:49,534 --> 00:24:51,174 well this is a hard one 751 00:24:51,174 --> 00:24:53,205 on paper the shuttle would cost around 752 00:24:53,210 --> 00:24:55,085 2014 $1000000 per seat 753 00:24:55,094 --> 00:24:57,165 but don't forget the shuttle did a lot 754 00:24:57,174 --> 00:24:58,645 more than just take crew up 755 00:24:58,814 --> 00:25:01,374 it often would carry an additional payload of a dozen 756 00:25:01,374 --> 00:25:02,525 tons or more 757 00:25:03,120 --> 00:25:05,489 so maybe it's fair to take that 214 758 00:25:05,489 --> 00:25:07,470 $1000000 per seat per launch 759 00:25:07,729 --> 00:25:09,870 and then take 80 off 760 00:25:09,969 --> 00:25:12,190 because 80 of the volume of the vehicle 761 00:25:12,209 --> 00:25:14,070 was dedicated to cargo 762 00:25:14,520 --> 00:25:16,316 but maybe that's not fair either 763 00:25:16,316 --> 00:25:18,963 so let's just say it's somewhere between 43 million 764 00:25:19,116 --> 00:25:20,763 and 214 million 765 00:25:20,916 --> 00:25:21,956 the last thing I want to mention 766 00:25:21,956 --> 00:25:24,356 but only for the starling and crew dragon is their 767 00:25:24,356 --> 00:25:25,723 cost of development 768 00:25:26,070 --> 00:25:28,871 so the starling I received 4.8 billion 769 00:25:28,948 --> 00:25:31,751 and spacex received 3.1 billion in total 770 00:25:31,868 --> 00:25:32,908 but this includes two 771 00:25:32,908 --> 00:25:33,828 demo launches and 772 00:25:33,828 --> 00:25:36,148 six operational flights from each company 773 00:25:36,148 --> 00:25:37,908 now I don't really want to get into a spitting match 774 00:25:37,908 --> 00:25:38,508 over why 775 00:25:38,508 --> 00:25:40,631 each company got paid such different amounts 776 00:25:40,980 --> 00:25:43,572 but it likely had to do with each company's proposal 777 00:25:43,600 --> 00:25:45,960 perhaps after spacex flies a few dozen astronauts 778 00:25:45,960 --> 00:25:46,947 they can charge a little more 779 00:25:46,947 --> 00:25:48,812 for increased confidence from nasa 780 00:25:49,200 --> 00:25:49,928 kind of like how they're 781 00:25:49,928 --> 00:25:52,008 able to increase the price of the cargo resupply 782 00:25:52,008 --> 00:25:54,791 missions once they proved to be reliable and 783 00:25:54,928 --> 00:25:55,768 after they gained a better 784 00:25:55,768 --> 00:25:57,831 sense of the cost of running the program 785 00:25:57,928 --> 00:26:00,151 so when it's all said and done here's my opinion 786 00:26:00,328 --> 00:26:00,951 1st off 787 00:26:01,368 --> 00:26:03,940 I couldn't be more excited to see an awesome pair of 788 00:26:03,940 --> 00:26:05,431 exciting new rides to space 789 00:26:05,940 --> 00:26:07,280 it's about time 790 00:26:07,560 --> 00:26:09,760 as solid and reliable as the soyuz has been 791 00:26:10,200 --> 00:26:11,760 it's about time humans have other 792 00:26:11,880 --> 00:26:13,960 newer and more comfortable options 793 00:26:13,960 --> 00:26:15,520 as far as each system goes 794 00:26:15,520 --> 00:26:17,800 I've got my opinions and I'll keep them short 795 00:26:18,030 --> 00:26:20,490 because I already know the comment section will have 796 00:26:20,490 --> 00:26:22,470 plenty of opinions to go around 797 00:26:22,549 --> 00:26:25,189 the starling is an awesome spaceship 798 00:26:25,189 --> 00:26:26,429 it's very well thought out 799 00:26:26,429 --> 00:26:27,149 and you can tell 800 00:26:27,149 --> 00:26:28,669 human safety is very much 801 00:26:28,669 --> 00:26:31,309 on top of mine for both boeing and ula 802 00:26:31,309 --> 00:26:33,149 I'm glad to see they're going to be landing on land 803 00:26:33,149 --> 00:26:33,859 because I think it's cool 804 00:26:33,859 --> 00:26:36,270 and I'm glad to see they can reuse the spacecraft 805 00:26:36,480 --> 00:26:37,467 and I'm also happy 806 00:26:37,467 --> 00:26:39,560 the atlas will finally be carrying humans again 807 00:26:39,560 --> 00:26:40,394 for the first time 808 00:26:40,394 --> 00:26:44,645 since faith 7 launched with mercury atlas in 1963 809 00:26:44,714 --> 00:26:46,485 and as advance as the starling is 810 00:26:47,010 --> 00:26:49,889 I do wish boeing had gone a few steps more progressive 811 00:26:50,050 --> 00:26:51,610 it feels like the spaceship is just a little 812 00:26:51,610 --> 00:26:52,409 conservative 813 00:26:52,530 --> 00:26:54,089 and you can tell they didn't want to take 814 00:26:54,250 --> 00:26:56,969 any design risks or really push any boundaries 815 00:26:57,480 --> 00:26:58,859 unfortunately when I got to sit in it 816 00:26:58,859 --> 00:27:01,539 it just feels a little stale and cold 817 00:27:01,539 --> 00:27:04,620 however aesthetics and ergonomics are a very 818 00:27:04,899 --> 00:27:07,419 very minor part of the equation when you're putting 819 00:27:07,419 --> 00:27:08,820 humans in space 820 00:27:09,120 --> 00:27:12,329 so now we come to spacex's crew dragon capsule 821 00:27:12,329 --> 00:27:15,169 there's really no arguing that spacex made the better 822 00:27:15,169 --> 00:27:16,591 looking and downright 823 00:27:16,609 --> 00:27:17,911 sexy spaceship 824 00:27:18,272 --> 00:27:20,246 it truly is stunning 825 00:27:20,246 --> 00:27:21,046 and quite frankly 826 00:27:21,046 --> 00:27:23,126 the radical departure from the norm really 827 00:27:23,126 --> 00:27:25,113 seems to have been pulled off brilliantly 828 00:27:25,406 --> 00:27:26,140 just look at how 829 00:27:26,140 --> 00:27:27,446 easy it is to get into this thing 830 00:27:27,446 --> 00:27:28,686 compared to the starling 831 00:27:28,686 --> 00:27:29,753 and I have no doubt the crew 832 00:27:29,753 --> 00:27:32,153 dragon capsule didn't cut any corners in safety 833 00:27:32,460 --> 00:27:34,374 considering they had to answer to nasa on 834 00:27:34,465 --> 00:27:36,214 every single millimeter of the thing 835 00:27:36,585 --> 00:27:38,574 so when it comes to pure cool factor 836 00:27:39,480 --> 00:27:41,155 gonna have to give the leg up to spacex 837 00:27:41,155 --> 00:27:42,555 after hearing from a few people who have 838 00:27:42,555 --> 00:27:43,835 used the touchscreens 839 00:27:43,835 --> 00:27:45,764 we're talking about hardcore pilots here 840 00:27:45,995 --> 00:27:47,820 they have voiced missing a more 841 00:27:47,820 --> 00:27:49,164 traditional control scheme 842 00:27:49,470 --> 00:27:51,712 saying it does feel a little bit like flying an ipad 843 00:27:51,712 --> 00:27:54,107 but lastly seeing a falcon 9 844 00:27:54,192 --> 00:27:56,587 land after delivering crew to the iss will be a nice 845 00:27:56,650 --> 00:27:57,747 cherry on top 846 00:27:57,992 --> 00:27:58,872 and although of course 847 00:27:58,872 --> 00:28:00,907 it won't be landing back at kennedy space center 848 00:28:01,320 --> 00:28:03,168 I never get tired of seeing this 849 00:28:03,311 --> 00:28:05,928 so no matter how you cut it you can't go wrong 850 00:28:06,180 --> 00:28:07,151 nasa hired two 851 00:28:07,151 --> 00:28:09,860 incredible companies to come up with some truly 852 00:28:09,860 --> 00:28:11,488 exciting new rides to space 853 00:28:12,030 --> 00:28:13,918 nasa should be proud of this new program 854 00:28:14,061 --> 00:28:17,398 it saved them money and now offers a variety of options 855 00:28:17,541 --> 00:28:18,701 so now they actually have some 856 00:28:18,701 --> 00:28:22,038 overlap and redundancy in humanity's access to space 857 00:28:22,141 --> 00:28:22,781 and although this 858 00:28:22,781 --> 00:28:24,061 video was intended to highlight 859 00:28:24,061 --> 00:28:25,381 the commercial crew program 860 00:28:25,381 --> 00:28:26,541 to be perfectly honest 861 00:28:26,541 --> 00:28:29,541 I wound up really appreciating the space shuttle more 862 00:28:29,541 --> 00:28:30,518 after diving into this 863 00:28:30,900 --> 00:28:33,109 that thing was something really special 864 00:28:33,109 --> 00:28:35,250 I mean yes of course it had its flaws 865 00:28:35,389 --> 00:28:35,869 and it 866 00:28:35,869 --> 00:28:38,160 didn't quite live up to the hype of making spaceflight 867 00:28:38,160 --> 00:28:39,690 cheaper or safer 868 00:28:39,909 --> 00:28:43,730 but boy oh boy did it have some unmatched capabilities 869 00:28:43,830 --> 00:28:46,872 so great job nasa boeing and spacex 870 00:28:46,947 --> 00:28:48,987 I honestly couldn't be more excited for this 871 00:28:48,987 --> 00:28:50,392 new chapter of spaceflight 872 00:28:50,627 --> 00:28:52,032 and don't you all worry 873 00:28:52,187 --> 00:28:54,192 I'll be doing my best to bring it all to you guys 874 00:28:54,267 --> 00:28:55,907 I'm planning to try to make it down to 875 00:28:55,907 --> 00:28:57,587 all the demo missions and cover them 876 00:28:57,587 --> 00:28:58,672 live in
