to refuel, repair, and relocate

13
00:00:48,560 --> 00:00:52,600
life is limited by the amount of fuel they have. So if we can

00:00:52,620 --> 00:00:56,630
bring fuel to them, we can have their lives extended.

proving and maturing technologies required for satellite servicing.

20
00:01:16,960 --> 00:01:20,970
>>ALEX: So there are several things new and unique about this test itself. The first

21
00:01:20,990 --> 00:01:24,990
was that I was controlling the robot remotely from Greenbelt, Maryland while the robot was

22
00:01:25,010 --> 00:01:29,090
located down at Kennedy Space Center. The second was this was the first time

23
00:01:29,110 --> 00:01:33,180
we were actually transferring a hazardous fluid. The Robotic Refueling Mission

24
00:01:33,200 --> 00:01:37,230
on the Space Station transferred ethanol, which isn't a hazardous fluid and it's

25
00:01:37,250 --> 00:01:41,270
not actually a component of satellite fuel. >>BEN: On the International

26
00:01:41,290 --> 00:01:45,300
Space Station, we wanted to be sure to be safe around the astronauts.

27
00:01:45,320 --> 00:01:49,440
>>MATT: Here, what we're doing now is using actual spacecraft propellant.

28
00:01:49,460 --> 00:01:53,510
>>BRIAN: It's a very dangerous fluid, very deadly fluid. That's why

29
00:01:53,530 --> 00:01:57,550
we'll be in personal protective equipment, these full-assembly

30
00:01:57,570 --> 00:02:01,590
SCAPE suits, and that protects the people in the suit from any sort of

31
00:02:01,610 --> 00:02:05,610
exposure. ... 

32
00:02:05,630 --> 00:02:09,740
>>ALEX: So on the day of the test, I used the tool on the robot to attach to a satellite

33
00:02:09,760 --> 00:02:13,850
fill drain valve, where we then transferred fluid through the tool

34
00:02:13,870 --> 00:02:17,950
and into the satellite valve, simulating a refueling task.

35
00:02:17,970 --> 00:02:21,990
>>MATT: So as a tool designer, during the test, we need to make sure the tool is operating as we expect.

36
00:02:22,010 --> 00:02:26,030
So we sit right next to the robot operators, as they're driving the robot,

37
00:02:26,050 --> 00:02:30,050
we're looking at video, we're looking at telemetry, making sure that the tool is behaving

38
00:02:30,070 --> 00:02:34,170
as expected. >>ALEX: Operating the robotic arm remotely feels,

39
00:02:34,190 --> 00:02:38,240
it actually kinda feels a lot like a video game, because I'll have two joy-sticks in front of me that I'll be using

40
00:02:38,260 --> 00:02:42,290
to control the robot. And while it's moving very slowly, I'm looking at tool cameras in front of

41
00:02:42,310 --> 00:02:46,330
me, that show the end of the robot itself.
