1
00:00:11,450 --> 00:00:08,990
it's pretty desolate but at the same

2
00:00:13,129 --> 00:00:11,460
time to you what we're doing here is

3
00:00:21,109 --> 00:00:13,139
we're testing a sensor that is gonna be

4
00:00:24,019 --> 00:00:21,119
used for lunar landing over one just

5
00:00:26,420 --> 00:00:24,029
right down to build a road okay the

6
00:00:28,339 --> 00:00:26,430
situation that was faced by Apollo was

7
00:00:31,460 --> 00:00:28,349
going into what we consider very benign

8
00:00:33,049 --> 00:00:31,470
landing sites a lot of people think that

9
00:00:35,360 --> 00:00:33,059
the new lunar lander ease will be just

10
00:00:37,490 --> 00:00:35,370
like Apollo but the new landing sites

11
00:00:40,639 --> 00:00:37,500
are very challenging the illumination at

12
00:00:43,010 --> 00:00:40,649
the poles is very dim sun angle is very

13
00:00:45,500 --> 00:00:43,020
low to horizon because the moon has no

14
00:00:49,850 --> 00:00:45,510
atmosphere shadows are absolute and

15
00:00:51,920 --> 00:00:49,860
there's no diffusion of light Jeff to

16
00:00:53,299 --> 00:00:51,930
Moonraker one well this project is

17
00:00:55,160 --> 00:00:53,309
called al hat which stands for

18
00:00:57,500 --> 00:00:55,170
autonomous landing and hazard avoidance

19
00:00:59,389 --> 00:00:57,510
technology and we're testing out a

20
00:01:02,180 --> 00:00:59,399
helicopter that's flying over a lunar a

21
00:01:03,740 --> 00:01:02,190
strange in our analog seeing how good

22
00:01:12,109 --> 00:01:03,750
the sensor is at detecting these rocks

23
00:01:14,570 --> 00:01:12,119
up copy that all hat is a technology

24
00:01:17,570 --> 00:01:14,580
task that is building sensors and

25
00:01:20,359 --> 00:01:17,580
algorithms for landing on the moon and

26
00:01:22,480 --> 00:01:20,369
in particular for detecting hazards

27
00:01:25,249 --> 00:01:22,490
during landing and as well as

28
00:01:27,530 --> 00:01:25,259
automatically estimating the spacecraft

29
00:01:29,240 --> 00:01:27,540
position by looking at the surface of

30
00:01:31,789 --> 00:01:29,250
the moon to see features and then

31
00:01:34,550 --> 00:01:31,799
matching them to an onboard reference to

32
00:01:36,920 --> 00:01:34,560
compute position kind of like people

33
00:01:38,539 --> 00:01:36,930
when they navigate they look at a map we

34
00:01:40,130 --> 00:01:38,549
want to have the computer and the

35
00:01:43,940 --> 00:01:40,140
sensors do that automatically on the

36
00:01:45,800 --> 00:01:43,950
moon this is all autonomous assisting

37
00:01:48,080 --> 00:01:45,810
the pilot helping them determine

38
00:01:50,929 --> 00:01:48,090
automatically where hazards are in real

39
00:01:53,060 --> 00:01:50,939
time you know it's really a new

40
00:01:57,370 --> 00:01:53,070
capability that wasn't possible at all

41
00:02:02,029 --> 00:01:59,330
when you're getting lower in altitude

42
00:02:04,010 --> 00:02:02,039
and doing your final descent into the

43
00:02:05,389 --> 00:02:04,020
lunar surface those are the types of

44
00:02:07,880 --> 00:02:05,399
trajectories we're trying to test here

45
00:02:09,380 --> 00:02:07,890
we've got what we call a gyro-stabilized

46
00:02:11,509 --> 00:02:09,390
mount that the Hollywood industry uses

47
00:02:13,280 --> 00:02:11,519
for the movies get there nice smooth

48
00:02:15,050 --> 00:02:13,290
aerial shots so we take the movie

49
00:02:16,910 --> 00:02:15,060
cameras off and we put our instruments

50
00:02:18,800 --> 00:02:16,920
on so that instrument and the gimbal is

51
00:02:20,930 --> 00:02:18,810
the flashlight arm which is amazing

52
00:02:23,449 --> 00:02:20,940
we're testing right now flashlights are

53
00:02:25,339 --> 00:02:23,459
is an instrument that as a burst of

54
00:02:28,130 --> 00:02:25,349
light that comes out very very short

55
00:02:29,690 --> 00:02:28,140
bursts of light ejected from a laser

56
00:02:33,020 --> 00:02:29,700
aperture eight times the second

57
00:02:34,670 --> 00:02:33,030
derivative we have a receive optics

58
00:02:38,030 --> 00:02:34,680
exactly like a camera so you're getting

59
00:02:39,860 --> 00:02:38,040
a 3d picture so I'm in the back I have

60
00:02:41,449 --> 00:02:39,870
four computers back there to look at it

61
00:02:42,809 --> 00:02:41,459
as simultaneously so it's a little bit

62
00:02:44,699 --> 00:02:42,819
hectic sometimes

63
00:02:46,619 --> 00:02:44,709
you never really know it's something

64
00:02:48,599 --> 00:02:46,629
until we try to see how well it really

65
00:02:50,160 --> 00:02:48,609
works it's been a good test so far we're

66
00:02:53,099 --> 00:02:50,170
looking forward to getting into the meat

67
00:02:55,080 --> 00:02:53,109
ladies of the day night I'm very excited

68
00:02:57,270 --> 00:02:55,090
to be working on this project because I

69
00:02:59,190 --> 00:02:57,280
really think it has a chance of being on

70
00:03:01,709 --> 00:02:59,200
the next lunar lander and that's really

71
00:03:03,390 --> 00:03:01,719
why I work for NASA as to you know

72
00:03:05,789 --> 00:03:03,400
building technology that actually gets

73
00:03:08,399 --> 00:03:05,799
its use going back to the moon and

74
00:03:10,470 --> 00:03:08,409
possibly on to Mars is really what I

75
00:03:12,929 --> 00:03:10,480
want to be working on when you're

76
00:03:14,610 --> 00:03:12,939
operating up there it's it's pretty

77
00:03:16,379 --> 00:03:14,620
amazing to look down especially out here

78
00:03:17,819 --> 00:03:16,389
in the valley and no vegetation you're

79
00:03:19,830 --> 00:03:17,829
looking at this surface and thinking

80
00:03:21,509 --> 00:03:19,840
this could be the moon you know some

81
00:03:23,879 --> 00:03:21,519
future astronaut a couple years down the

82
00:03:25,259 --> 00:03:23,889
line when that happens it's going to be
