1 00:00:08,080 --> 00:00:04,040 (music) 2 00:00:08,100 --> 00:00:12,100 (beeping) 3 00:00:12,120 --> 00:00:16,150 Narrator: These days, one word drives high tech. 4 00:00:16,170 --> 00:00:20,200 Creativity. If nothing else, 5 00:00:20,220 --> 00:00:24,210 NASA’s Robotic Refueling Mission…RRM… is 6 00:00:24,230 --> 00:00:28,300 creativity embodied…and like all things creative, it’s not without 7 00:00:28,320 --> 00:00:32,380 challenges. Ben Reed: It’s not loading groceries into your shopping cart. It has 8 00:00:32,400 --> 00:00:36,600 It’s in a harsher environment. It’s going 18,000 9 00:00:36,620 --> 00:00:40,790 mph up in space. Spacecraft usually travel to orbit like museum 10 00:00:40,810 --> 00:00:44,870 pieces. They’re not meant to be fiddled with once they’re hung in their final destinations. 11 00:00:44,890 --> 00:00:48,900 But satellites are machines, and like all machines, 12 00:00:48,920 --> 00:00:52,920 fuel runs low. Parts wear out. 13 00:00:52,940 --> 00:00:57,000 RRM set out to prove that robots could repair them in space, 14 00:00:57,020 --> 00:01:01,050 without placing an astronaut at risk. It’s really hard to do… 15 00:01:01,070 --> 00:01:05,080 full of challenging problems. 16 00:01:05,100 --> 00:01:09,140 Ross Henry: …any problem is a solvable problem…and repairing satellites in space 17 00:01:09,160 --> 00:01:13,190 is not a new problem to solve. 18 00:01:13,210 --> 00:01:17,250 NASA has been wrestling with spacecraft on orbit for decades. 19 00:01:17,270 --> 00:01:21,380 Early efforts demanded human muscle. In 1984 20 00:01:21,400 --> 00:01:25,450 astronauts captured the Solar Max satellite for an 21 00:01:25,470 --> 00:01:29,500 astounding zero-G trip to the doctor. After a little TLC, 22 00:01:29,520 --> 00:01:33,630 it went back to work, good as new. 23 00:01:33,650 --> 00:01:37,670 The most famous orbital repairs happened with the Hubble Space Telescope. 24 00:01:37,690 --> 00:01:41,700 When astronauts paid it a final house-call in 2009, 25 00:01:41,720 --> 00:01:45,740 the billion dollar instrument got a new lease on life. 26 00:01:45,760 --> 00:01:49,830 Hugely expensive, extremely risky, the Hubble repair mission 27 00:01:49,850 --> 00:01:53,900 tested the bounds of human on-orbit capabilities…not to mention 28 00:01:53,920 --> 00:01:57,920 cost-benefit analysis. But mission success rein- 29 00:01:57,940 --> 00:02:02,040 reinforced the value of on-orbit repairs and the great Hubble Space Telescope 30 00:02:02,060 --> 00:02:06,140 continues to operate to this day. 31 00:02:06,160 --> 00:02:10,250 Complex machines, satellites are neither easily built nor replaced. 32 00:02:10,270 --> 00:02:14,320 Refueling and repairing them in space just makes 33 00:02:14,340 --> 00:02:18,390 sense. Ben Reed: Robots can do things that humans can’t do 34 00:02:18,410 --> 00:02:22,430 in terms of precision, in terms of control. Holding a particular spot 35 00:02:22,450 --> 00:02:26,530 for six hours while engineers on the ground debate what to do: we can’t 36 00:02:26,550 --> 00:02:30,550 ask a human to do that. 37 00:02:30,570 --> 00:02:34,580 Narrator: Will robots make astronauts obsolete? 38 00:02:34,600 --> 00:02:38,640 Not a chance, and the reason why is pretty awesome. 39 00:02:38,660 --> 00:02:42,750 Think of a car…like this…in for repairs. 40 00:02:42,770 --> 00:02:46,790 A mechanic can slide underneath…try to reach tough spots. But with 41 00:02:46,810 --> 00:02:50,890 a mechanical lift, repair options expand. 42 00:02:50,910 --> 00:02:54,940 Machines like this…like robots…act as enablers rather than 43 00:02:54,960 --> 00:02:58,960 replacements. Robots free astronauts from certain time consuming 44 00:02:58,980 --> 00:03:03,020 and risky operations. Astronaut time is better spent on 45 00:03:03,040 --> 00:03:07,110 command and control issues, as well as valuable research and exploration. 46 00:03:07,130 --> 00:03:11,160 Robots can also travel places astronauts are not 47 00:03:11,180 --> 00:03:15,170 likely to go. Teri Gregory: Other projects have been out to geosynchronous orbit 48 00:03:15,190 --> 00:03:19,270 and have spacecraft there and have been there for years. So we know what materials 49 00:03:19,290 --> 00:03:23,390 work there, we know what the environment is there, and we can use that information 50 00:03:23,410 --> 00:03:27,420 to build on what we’re going to do when we build our spacecraft to go there. 51 00:03:27,440 --> 00:03:31,450 Narrator: As NASA prepared to launch the final space 52 00:03:31,470 --> 00:03:35,580 shuttle, the Satellite Servicing Capabilities Office pressed forward 53 00:03:35,600 --> 00:03:39,650 with an idea. A test…designed to see if robot 54 00:03:39,670 --> 00:03:43,730 technology was up to the job. In eighteen months 55 00:03:43,750 --> 00:03:47,750 the team designed the essential RRM experiments, 56 00:03:47,770 --> 00:03:51,930 getting hardware built, launched, and installed on the International Space Station. 57 00:03:51,950 --> 00:03:55,960 Teri Gregory: “We had a very aggressive schedule to launch in 2011 to make it 58 00:03:55,980 --> 00:03:59,970 onto the last shuttle flight, which we succeeded in doing. Ross Henry: So 59 00:03:59,990 --> 00:04:04,000 We always say we want to test as we fly. We want to test, test, and test 60 00:04:04,020 --> 00:04:08,070 again. Narrator: They did. The team completed a series 61 00:04:08,090 --> 00:04:12,170 delicate maneuvers, custom robotic tools standing in 62 00:04:12,190 --> 00:04:16,210 for astronaut fingers. RRM’s to-do 63 00:04:16,230 --> 00:04:20,270 list looked easy. Unscrew this, cut that, refill a tank like 64 00:04:20,290 --> 00:04:24,310 pulling up to the low octane pump, right? No. 65 00:04:24,330 --> 00:04:28,340 Not easy at all. Day two, in fact came to a halt 66 00:04:28,360 --> 00:04:32,400 halfway in the middle when engineers overseeing the robotic arm had some concerns. 67 00:04:32,420 --> 00:04:36,440 A crisis? Ben Reed: It certainly caught our attention, but it 68 00:04:36,460 --> 00:04:40,190 wasn’t a heart pounding moment. Not by any stretch. Narrator: And that’s the thing about missions 69 00:04:40,210 --> 00:04:44,300 like this. They demand the best from teams, and people 70 00:04:44,320 --> 00:04:48,450 don’t get on the team unless they’re willing to bring their A-game. 71 00:04:48,470 --> 00:04:52,600 On Day six, 72 00:04:52,620 --> 00:04:56,620 the team put three years of planning to work. With ethanol streaming 73 00:04:56,640 --> 00:05:00,710 into a test tank on orbit, engineers watched the data stream back to earth. 74 00:05:00,730 --> 00:05:04,740 There wasn’t much to see…but that wasn’t the point. 75 00:05:04,760 --> 00:05:08,770 It was a first. Word came over comms, loud and clear. 76 00:05:08,790 --> 00:05:12,820 SOT “you would agree…we have fluid transfer in progress.” 77 00:05:12,840 --> 00:05:16,840 No cheering yet. The team was still in 78 00:05:16,860 --> 00:05:20,920 the mission, and there were still jobs to do. 79 00:05:20,940 --> 00:05:25,030 Finally, 80 00:05:25,050 --> 00:05:29,090 simulated fuel transferred, the team moved to detach the valve. 81 00:05:29,110 --> 00:05:33,200 (music) 82 00:05:33,220 --> 00:05:37,280 Real experiments often yield interesting results. 83 00:05:37,300 --> 00:05:41,370 But after so much hard work, some things 84 00:05:41,390 --> 00:05:45,420 are just to be expected. (clapping) 85 00:05:45,440 --> 00:05:49,450 NASA’s reasons for doing this work go beyond the obvious. In 86 00:05:49,470 --> 00:05:53,590 fact, the deeper value for the nation…is ingenious. 87 00:05:53,610 --> 00:05:57,700 Ben Reed: I don’t want my job to be refueling communication birds for a living. 88 00:05:57,720 --> 00:06:01,730 I truly do not. I want to do it one time, kickstart a commercial 89 00:06:01,750 --> 00:06:05,750 industry that can then do it competitively. Narrator: This work helps 90 00:06:05,770 --> 00:06:09,820 open the door to a whole new kind of aerospace business. 91 00:06:09,840 --> 00:06:13,870 Big business. Engineering in space: 92 00:06:13,890 --> 00:06:17,940 inventive, daring, smart…and RRM 93 00:06:17,960 --> 00:06:22,070 delivered them all. But the big picture? There’s only one 94 00:06:22,090 --> 00:06:26,110 word that will suffice: …creative. 95 00:06:26,130 --> 00:06:30,180 Ross Henry: If you think RRM was incredible you guys haven’t seen anything yet. 96 00:06:30,200 --> 00:06:34,330 (beeping)
