Hi, my name is Alex Janas.  I'm a robotic operator here at the 

4
00:00:12,100 --> 00:00:16,100
Servicing Technology Center. [ music ] So the test I want

5
00:00:16,120 --> 00:00:20,110
to talk to you guys about today is called RROxiTT, and this is a 

6
00:00:20,130 --> 00:00:24,170
remote fluid transfer test, which is going to be performed by taking this robot and sending it

7
00:00:24,190 --> 00:00:28,210
down to Kennedy Space Center in Florida. And myself, I'm going to be the operator

8
00:00:28,230 --> 00:00:32,240
right here at NASA Goddard. Some of the challenging aspects of this task 

9
00:00:32,260 --> 00:00:36,250
include this valve. This is a standard satellite valve that they use for filling a satellite with fuel

10
00:00:36,270 --> 00:00:40,270
on the ground, and then it's sealed up and never meant to be opened again in space.

11
00:00:40,290 --> 00:00:44,320
My job is going to be to fly up, align to, and access this servicing valve. 

12
00:00:44,340 --> 00:00:48,360
So if you can imagine, this would be a servicing arm in space;

13
00:00:48,380 --> 00:00:52,380
this tool would be our tool; and this would access a satellite that's already in space. 

14
00:00:52,400 --> 00:00:56,400
Another hard aspect about this test is that I'm going to be commanding this robot from

15
00:00:56,420 --> 00:01:00,420
here at NASA Goddard. So now I'm commanding it and I'm telling the robot to go forward,

16
00:01:00,440 --> 00:01:04,460
up, down, left, right, and align it; there's going to be a time delay from when I send the robot a

17
00:01:04,480 --> 00:01:08,500
command and when the robot actually receives the command itself. So the fluid that we're

18
00:01:08,520 --> 00:01:12,510
going to be using during this test is called NTO, and it's one of two fluids that are combined

19
00:01:12,530 --> 00:01:16,530
in a spacecraft in order to create an explosion to propel a spacecraft forward in space. 

20
00:01:16,550 --> 00:01:20,540
Now this is very corrosive, dangerous fluid, so when we're performing the test down in Florida, 

21
00:01:20,560 --> 00:01:24,590
any humans within several hundred feet of the work site actually have to be wearing

22
00:01:24,610 --> 00:01:28,630
huge, big safety protective gear. This test is all part of a greater effort

23
00:01:28,650 --> 00:01:32,660
to continue maturing and advancing the technology needed to repair and refuel

24
00:01:32,680 --> 00:01:36,670
satellites in space so that they'll last longer. So tune in

25
00:01:36,690 --> 00:01:40,690
in early 2014 to watch me drive this robot and perform the actual refueling test.
