1 00:00:11,720 --> 00:00:09,920 I live for somebody to tell me you can't 2 00:00:13,910 --> 00:00:11,730 do that it'll never work but you 3 00:00:15,949 --> 00:00:13,920 wouldn't be crazy to wonder if sending a 4 00:00:19,250 --> 00:00:15,959 robot to refuel an operational 5 00:00:21,340 --> 00:00:19,260 spacecraft might run that risk but you 6 00:00:24,620 --> 00:00:21,350 know engineers have imaginations 7 00:00:27,520 --> 00:00:24,630 consider this every satellite flying 8 00:00:30,830 --> 00:00:27,530 right now is bespoke hand-wrought 9 00:00:33,560 --> 00:00:30,840 customized detailed and extremely 10 00:00:35,510 --> 00:00:33,570 expensive that's why it pays to figure 11 00:00:38,000 --> 00:00:35,520 out how to repair and refuel the things 12 00:00:40,850 --> 00:00:38,010 rather than just replace them there's 13 00:00:43,069 --> 00:00:40,860 just one problem that's hard to do just 14 00:00:45,139 --> 00:00:43,079 getting the robot to go where you want 15 00:00:46,430 --> 00:00:45,149 it to go they don't position precisely 16 00:00:48,440 --> 00:00:46,440 so you have to do things like build 17 00:00:49,400 --> 00:00:48,450 leading into the tool an astronaut could 18 00:00:51,500 --> 00:00:49,410 probably just get it right on there 19 00:00:53,690 --> 00:00:51,510 because he's right there just like 20 00:00:55,729 --> 00:00:53,700 performing at Carnegie Hall satellite 21 00:00:58,520 --> 00:00:55,739 repair missions demand rigorous practice 22 00:01:00,709 --> 00:00:58,530 and the big practice session on deck is 23 00:01:03,200 --> 00:01:00,719 called robotic refueling mission or RRM 24 00:01:05,450 --> 00:01:03,210 at Maryland's Goddard Space Flight 25 00:01:07,910 --> 00:01:05,460 Center mission planners use a motion 26 00:01:11,060 --> 00:01:07,920 simulation platform to figure out how to 27 00:01:14,000 --> 00:01:11,070 get all the parts working together when 28 00:01:17,120 --> 00:01:14,010 a robot arm clips a wire this fall it'll 29 00:01:19,070 --> 00:01:17,130 be one small snip for robots one giant 30 00:01:22,609 --> 00:01:19,080 leap in the business of space-based 31 00:01:24,260 --> 00:01:22,619 satellite servicing the last space 32 00:01:26,030 --> 00:01:24,270 shuttle flight delivered Hardware 33 00:01:28,880 --> 00:01:26,040 looking a lot like this right to 34 00:01:31,039 --> 00:01:28,890 International Space Station it's a box 35 00:01:34,219 --> 00:01:31,049 of practice equipment a busy board 36 00:01:35,840 --> 00:01:34,229 valves nozzles clamps and more to 37 00:01:39,080 --> 00:01:35,850 simulate the side of an actual satellite 38 00:01:41,749 --> 00:01:39,090 a Canadian robot called Dexter will 39 00:01:43,370 --> 00:01:41,759 interact with the practice gear it's 40 00:01:45,859 --> 00:01:43,380 different in space than here on the 41 00:01:48,109 --> 00:01:45,869 ground but that's kind of the point the 42 00:01:51,410 --> 00:01:48,119 whole thing is a learning experience a 43 00:01:53,480 --> 00:01:51,420 big one we're showing folks that we have 44 00:01:56,120 --> 00:01:53,490 the capability to use the existing robot 45 00:01:58,340 --> 00:01:56,130 it was not meant to be used with tools 46 00:02:01,190 --> 00:01:58,350 to work on our M and we've adapted those 47 00:02:03,530 --> 00:02:01,200 tools to make them compatible with the 48 00:02:05,090 --> 00:02:03,540 Dexter robot and also compatible with 49 00:02:07,730 --> 00:02:05,100 our mock satellite interfaces that we 50 00:02:10,490 --> 00:02:07,740 have on our M the robot is a very stiff 51 00:02:12,619 --> 00:02:10,500 rigid interface it's not forgiving like 52 00:02:14,360 --> 00:02:12,629 an astronauts hand when you push on 53 00:02:15,769 --> 00:02:14,370 something really hard with the robot you 54 00:02:17,330 --> 00:02:15,779 build up really large contact forces 55 00:02:19,159 --> 00:02:17,340 when the astronaut feeds on something 56 00:02:20,390 --> 00:02:19,169 his wrist might give you know that's 57 00:02:22,069 --> 00:02:20,400 he's got his own 58 00:02:24,140 --> 00:02:22,079 internal sort of software compliance 59 00:02:26,240 --> 00:02:24,150 running station astronauts won't be 60 00:02:28,819 --> 00:02:26,250 involved this will be a mission run from 61 00:02:31,520 --> 00:02:28,829 the ground our RM will demonstrate a 62 00:02:33,520 --> 00:02:31,530 number of essential tasks at the end 63 00:02:36,050 --> 00:02:33,530 it'll attempt first-of-its-kind 64 00:02:38,509 --> 00:02:36,060 simulated fuel transfer between two 65 00:02:40,759 --> 00:02:38,519 pieces of hardware not so easy when 66 00:02:43,429 --> 00:02:40,769 you're orbiting the planet at 18,000 67 00:02:46,759 --> 00:02:43,439 miles an hour it's really exciting to 68 00:02:49,670 --> 00:02:46,769 feel like you're working at the front of 69 00:02:53,390 --> 00:02:49,680 the way and the work that our team is 70 00:02:55,399 --> 00:02:53,400 doing is it's uncharted territory the 71 00:02:58,069 --> 00:02:55,409 robotic refueling mission augers a 72 00:03:00,649 --> 00:02:58,079 revolution in spacecraft operation and 73 00:03:03,379 --> 00:03:00,659 design it may be a rehearsal for bigger 74 00:03:05,780 --> 00:03:03,389 things to come but it's also a direct
