2
00:00:05.680 --> 00:00:09.100
I think that it's in human nature to
explore. Understanding the moon better

3
00:00:09.100 --> 00:00:11.560
[music]

4
00:00:11.580 --> 00:00:16.940
Understanding the moon better will help us to understand our neighbors in the solar system.

5
00:00:16.949 --> 00:00:22.050
We're exploiting the solar system here
not just the moon. The moon is the

6
00:00:22.050 --> 00:00:27.400
natural next step in in our exploration
of our own universe.

7
00:00:27.400 --> 00:00:34.700
[music]

8
00:00:34.700 --> 00:00:38.940
[Tooley] The Lunar Reconnaissance Orbiter is as
its namesake says a reconnaissance

9
00:00:38.950 --> 00:00:43.330
mission to the moon. Our job is to take a
suite of very powerful scientific

10
00:00:43.330 --> 00:00:47.590
instruments and make an atlas of the
entire moon. In some places in very great

11
00:00:47.590 --> 00:00:53.020
detail, topography, mountain heights,
mineralogy, temperatures, abundances of

12
00:00:53.020 --> 00:00:56.230
resources including potentially the
intriguing possibility that there's

13
00:00:56.230 --> 00:00:59.110
water at the moon. We put all this
together and do a data set by playing

14
00:00:59.110 --> 00:01:03.190
low over the moon for a year this is the
data that the people designing the

15
00:01:03.190 --> 00:01:08.229
systems picking the site's need to take
us back to the moon. [Vondrak] Well we learned much

16
00:01:08.229 --> 00:01:12.760
about the moon from the Apollo program
but now we want to return to the moon

17
00:01:12.760 --> 00:01:17.740
for a more intensive study. We want to be
able to go back to the moon so that we

18
00:01:17.740 --> 00:01:22.240
can live there for long periods and work
on the moon. So we need a mission that

19
00:01:22.240 --> 00:01:27.920
can help us find the best places to go
and determine how to go back there safely.

20
00:01:27.920 --> 00:01:31.620
[music]

21
00:01:31.620 --> 00:01:34.600
[Peddie] We know that you know Neil
Armstrong and some of the others had a

22
00:01:34.600 --> 00:01:38.740
difficult time finding a safe landing
site. They didn't see it till they got

23
00:01:38.740 --> 00:01:42.609
there. But now with with our instruments
we'll be able to tell people ahead of

24
00:01:42.609 --> 00:01:48.939
time look don't go there. [Vondrak]  LRO will have a
laser system that will give us a high

25
00:01:48.939 --> 00:01:54.640
resolution topographic map of the moon.
It also has high resolution cameras that

26
00:01:54.640 --> 00:01:59.920
will identify objects that are only a
foot or two in size so that we know

27
00:01:59.920 --> 00:02:04.719
where there are no large boulders that
could be a risk to astronauts. [Tooley] So our job

28
00:02:04.719 --> 00:02:07.509
is to literally complete the job of
mapping the moon do it at high

29
00:02:07.509 --> 00:02:12.910
resolutions and enable enable the
designers of the human systems, the Atlas

30
00:02:12.910 --> 00:02:16.600
they need to pick the safe places to go
the beneficial places to go and where

31
00:02:16.600 --> 00:02:18.040
it's most fruitful to go.

32
00:02:18.040 --> 00:02:21.680
[music]

33
00:02:21.680 --> 00:02:25.560
[Peddie] In addition to the safe landing sites,
LRO is looking for potential resources.

34
00:02:25.569 --> 00:02:29.590
And why are we doing that?
Because it's it's really hard to carry

35
00:02:29.590 --> 00:02:33.849
all your supplies with you. I mean you
can do it but you really spend a lot of

36
00:02:33.849 --> 00:02:38.439
not only fuel but cargo space. So it'd be
really nice to go to a place that

37
00:02:38.439 --> 00:02:44.019
already has the resources. Whether it's
water ice to have water or potential

38
00:02:44.019 --> 00:02:48.340
minerals that we could use as raw
materials to make into things that we

39
00:02:48.340 --> 00:02:53.049
would need. [Vondrak] We think the most interesting
parts of the Moon may be the polar

40
00:02:53.049 --> 00:02:58.359
regions of the Moon. Because there could
be resources there and so we're going to

41
00:02:58.359 --> 00:03:03.819
study intensively the polar regions with
LRO. [Tooley] From the Apollo era we chose to go

42
00:03:03.819 --> 00:03:07.180
for good reasons because it was
literally the easiest to go to the

43
00:03:07.180 --> 00:03:11.040
equatorial regions and stay a very short
time and was very ambitious program. But

44
00:03:11.040 --> 00:03:15.579
but when you look at where would you
like to go and stay for a while on the

45
00:03:15.579 --> 00:03:20.340
moon. You begin to realize that probably
the poles are the most interesting place

46
00:03:20.340 --> 00:03:25.629
[Keller] Access to solar power continuously that
may be the first and most important

47
00:03:25.629 --> 00:03:30.849
reason over you know the near term. And
then the possibility of resources being

48
00:03:30.849 --> 00:03:35.769
there. Those may take much longer time
before we're able to really exploit

49
00:03:35.769 --> 00:03:41.139
those. But the solar power is something
we can exploit right away.

50
00:03:41.139 --> 00:03:46.180
[Vondrak] The second big resource on the moon may
be water ice. There's evidence from

51
00:03:46.180 --> 00:03:52.359
earlier missions that in dark places at
the poles there may be water at the

52
00:03:52.359 --> 00:03:57.629
surface or below the surface in the form
of ice crystals. If it is abundant

53
00:03:57.629 --> 00:04:04.090
astronauts could use this for both human
consumption and as a source of rocket

54
00:04:04.090 --> 00:04:08.540
fuel LRO.

55
00:04:08.540 --> 00:04:13.180
LRO will measure for the first time
this very energetic component of the

56
00:04:13.180 --> 00:04:17.700
space radiation environment in order to
see whether it's going to be a problem

57
00:04:17.709 --> 00:04:23.949
for humans or not. [Tooley] It was one thing to go
for a handful of days in Apollo and go

58
00:04:23.949 --> 00:04:27.880
when you knew that the Sun was quiet or
you hope the Sun stayed quiet.

59
00:04:27.880 --> 00:04:32.620
And you took the risk you calculated the
risk of cancer and such in and you made

60
00:04:32.620 --> 00:04:35.410
a short mission. You're gonna live there
longer you need to you need to

61
00:04:35.410 --> 00:04:39.460
understand it well enough to go here's
what I need to do to protect myself.

62
00:04:39.460 --> 00:04:45.490
[Peddie] One of the things that we're looking for in
the LRO mission is how the high

63
00:04:45.490 --> 00:04:50.710
radiation environment affects our
ability to explore. So if we bring

64
00:04:50.710 --> 00:04:56.440
cameras or communication devices you
know how will they be impacted by the

65
00:04:56.440 --> 00:05:01.800
cosmic radiation? We need to protect our
equipment as well as ourselves.

66
00:05:01.800 --> 00:05:09.280
[music]

67
00:05:09.280 --> 00:05:13.930
[Tooley] When we look back to what we did in LRO and we look at what followed. I think we'll see

68
00:05:13.930 --> 00:05:19.810
a profound impact. We'll see us is really
being the small first step where we have

69
00:05:19.810 --> 00:05:23.560
human beings permanently off this planet,
getting to move out into the solar

70
00:05:23.560 --> 00:05:27.250
system starting with the moon. As that
pans out I think I think will be a small

71
00:05:27.250 --> 00:05:31.390
piece of a profound development that
when history looks back to say this time

72
00:05:31.390 --> 00:05:36.130
we went back to the moon this time we we
stayed and we when we moved on from

73
00:05:36.130 --> 00:05:38.370
there.

74
00:05:38.370 --> 00:05:47.420
