25
00:01:03,750 --> 00:01:00,160
cargo plane that landed at cape

26
00:01:06,149 --> 00:01:03,760
canaveral air force station skid strip

27
00:01:08,070 --> 00:01:06,159
in march lro underwent black light

28
00:01:10,390 --> 00:01:08,080
inspections to detect any possible

29
00:01:13,350 --> 00:01:10,400
particulate micro contamination

30
00:01:14,070 --> 00:01:13,360
my new cracks or fluid leaks and by

31
00:01:17,350 --> 00:01:14,080
april

32
00:01:19,350 --> 00:01:17,360
lro had its solar arrays installed

33
00:01:21,670 --> 00:01:19,360
in the meantime the systems and science

34
00:01:24,630 --> 00:01:21,680
instruments of lcross were prepared and

35
00:01:26,870 --> 00:01:24,640
tested for the rigors of this mission

36
00:01:28,230 --> 00:01:26,880
in late april the rocket's first stage

37
00:01:29,910 --> 00:01:28,240
or booster stage

38
00:01:31,990 --> 00:01:29,920
was transported to the vertical

39
00:01:35,510 --> 00:01:32,000
integration facility at launch complex

40
00:01:37,749 --> 00:01:35,520
41 on cape canaveral air force station

41
00:01:38,870 --> 00:01:37,759
the centaur second stage also known as

42
00:01:40,789 --> 00:01:38,880
the upper stage

43
00:01:43,670 --> 00:01:40,799
was later moved out of the hangar and

44
00:01:47,030 --> 00:01:43,680
hoisted atop the booster stage

45
00:01:49,030 --> 00:01:47,040
by may 15 the atlas v centaur stack was

46
00:01:51,749 --> 00:01:49,040
ready to be moved to the launch pad for

47
00:01:53,670 --> 00:01:51,759
a wet dress rehearsal or countdown test

48
00:01:54,870 --> 00:01:53,680
this means the vehicle was fully loaded

49
00:01:58,149 --> 00:01:54,880
with liquid hydrogen

50
00:02:02,230 --> 00:01:58,159
liquid oxygen and rp-1 propellants and

51
00:02:04,469 --> 00:02:02,240
tested on may 28th the spacecraft was

52
00:02:07,670 --> 00:02:04,479
transported to launch complex 41

53
00:02:10,150 --> 00:02:07,680
for mating with the atlas v rocket with

54
00:02:12,790 --> 00:02:10,160
these pre-launch milestones complete

55
00:02:13,990 --> 00:02:12,800
lro and l cross are now ready to journey

56
00:02:16,630 --> 00:02:14,000
to the moon

57
00:02:18,390 --> 00:02:16,640
lro to find safe landing sites and

58
00:02:20,790 --> 00:02:18,400
available resources

59
00:02:22,229 --> 00:02:20,800
and lcross to plunge into one of the

60
00:02:24,790 --> 00:02:22,239
polar caps to expose

61
00:02:26,869 --> 00:02:24,800
possible evidence of water ice the

62
00:02:28,229 --> 00:02:26,879
tucson will help pave the way for humans
