1
00:01:33,460 --> 00:02:36,710
you

2
00:02:42,420 --> 00:02:39,180
good morning Atlanta is planning ship is

3
00:02:44,220 --> 00:02:42,430
here with you how you doing today good

4
00:02:47,699 --> 00:02:44,230
boy Houston nice to hear your voice

5
00:02:49,710 --> 00:02:47,709
we're all with you okay Ken and we have

6
00:02:52,410 --> 00:02:49,720
some work for you today I hate to get

7
00:02:55,590 --> 00:02:52,420
you started so early but if you could go

8
00:02:58,050 --> 00:02:55,600
on up to spec 20 the forward Jets are

9
00:03:06,690 --> 00:02:58,060
getting a little cold we'd like to get

10
00:03:09,390 --> 00:03:06,700
some firings on them but we need to

11
00:03:11,340 --> 00:03:09,400
select a three on the dev so that would

12
00:03:12,570 --> 00:03:11,350
be an item 1 plus 3 that'll tighten the

13
00:03:23,619 --> 00:03:12,580
dead bands and get us a couple of

14
00:03:29,240 --> 00:03:26,690
Houston Atlantis with answers for the

15
00:03:34,210 --> 00:03:29,250
head of that questions okay we're ready

16
00:03:41,539 --> 00:03:37,339
Tyler bulky htn for Grand Rapids

17
00:03:43,490 --> 00:03:41,549
Michigan as a pretty confident and what

18
00:03:47,570 --> 00:03:43,500
ways is the MIR space station better

19
00:03:49,130 --> 00:03:47,580
than the space shuttle and we started to

20
00:03:51,229 --> 00:03:49,140
try to come up with the list of ways and

21
00:03:53,240 --> 00:03:51,239
then realize what you would really be

22
00:03:55,180 --> 00:03:53,250
comparing our apples and oranges are

23
00:03:58,339 --> 00:03:55,190
really two completely different vehicles

24
00:04:01,240 --> 00:03:58,349
here of course was designed to stay on

25
00:04:04,009 --> 00:04:01,250
orbit for a long time and it's

26
00:04:06,610 --> 00:04:04,019
approaching nearly 10 years old orbit

27
00:04:11,240 --> 00:04:06,620
the Space Shuttle was designed for

28
00:04:15,050 --> 00:04:11,250
frequent trips to at that space caring

29
00:04:19,039 --> 00:04:15,060
and fairly large amount of cargo so to

30
00:04:22,250 --> 00:04:19,049
say beer is better than the shuttle in

31
00:04:24,890 --> 00:04:22,260
some ways is only true because it does a

32
00:04:27,640 --> 00:04:24,900
different job so for sale in orbit for

33
00:04:31,400 --> 00:04:27,650
very long time near does have advantages

34
00:04:34,550 --> 00:04:31,410
if that is expandable they can change

35
00:04:37,900 --> 00:04:34,560
the configuration much more living

36
00:04:43,010 --> 00:04:37,910
volume in fear that we do it the shuttle

37
00:04:45,409 --> 00:04:43,020
also totally restored would say they say

38
00:04:48,980 --> 00:04:45,419
we taste not have to carry liquid oxygen

39
00:04:51,920 --> 00:04:48,990
and hydrogen to generate electricity on

40
00:04:54,110 --> 00:04:51,930
the other hand the shuttle has

41
00:04:56,839 --> 00:04:54,120
advantages at being able to carry large

42
00:04:59,600 --> 00:04:56,849
payloads and a large number of people to

43
00:05:04,040 --> 00:04:59,610
a problem a low-earth orbit it's also a

44
00:05:06,440 --> 00:05:04,050
reusable space vehicle so they're just

45
00:05:09,950 --> 00:05:06,450
decide for two very different purposes

46
00:05:15,339 --> 00:05:09,960
so comparing them is perhaps are not up

47
00:05:17,779 --> 00:05:15,349
not something that's very easy to do

48
00:05:22,730 --> 00:05:17,789
okay bill we copy dad won't pass that

49
00:05:25,700 --> 00:05:22,740
along thanks very much ok the next word

50
00:05:30,260 --> 00:05:25,710
is for bill bill derbyshire age 40

51
00:05:32,630 --> 00:05:30,270
Aberdeen New Jersey bill and asks why we

52
00:05:34,880 --> 00:05:32,640
throw away the external tank he writes

53
00:05:36,930 --> 00:05:34,890
it seems a waste to throw away the ET

54
00:05:38,700 --> 00:05:36,940
just as you attain orbit would

55
00:05:40,080 --> 00:05:38,710
make sense to at least parts of the use

56
00:05:43,200 --> 00:05:40,090
tanks and save this valuable resource

57
00:05:45,660 --> 00:05:43,210
for future visions and while certainly

58
00:05:48,540 --> 00:05:45,670
we hate not to conserve all the

59
00:05:50,490 --> 00:05:48,550
resources that we can in order to park

60
00:05:52,590 --> 00:05:50,500
an external tank on orbit we would have

61
00:05:55,200 --> 00:05:52,600
to be able to circularize its orbit

62
00:05:56,940 --> 00:05:55,210
which would mean either carrying it all

63
00:06:02,070 --> 00:05:56,950
the way to low-earth orbit with the

64
00:06:04,170 --> 00:06:02,080
shuttle in which case it would remain it

65
00:06:07,200 --> 00:06:04,180
or in orbit with Charlotte would

66
00:06:11,100 --> 00:06:07,210
ultimately be a hazard to other vehicles

67
00:06:13,530 --> 00:06:11,110
also without self-contained propulsive

68
00:06:16,770 --> 00:06:13,540
devices its orbit would serve decay and

69
00:06:19,290 --> 00:06:16,780
it would reenter anyway and then also

70
00:06:21,900 --> 00:06:19,300
even to another alternative would be to

71
00:06:23,910 --> 00:06:21,910
have a self-contained propulsion device

72
00:06:26,670 --> 00:06:23,920
on the external tank in which case it

73
00:06:29,100 --> 00:06:26,680
could circularize its own orbit but in

74
00:06:32,730 --> 00:06:29,110
idiot k any case the cost to do that

75
00:06:35,700 --> 00:06:32,740
would probably be significantly higher

76
00:06:39,330 --> 00:06:35,710
that the conservation of resources we

77
00:06:44,430 --> 00:06:39,340
would realize by keeping the excel tanks

78
00:06:54,970 --> 00:06:44,440
a little bit okay bill would copy that

79
00:07:02,080 --> 00:06:58,720
and all our staff with a third one here

80
00:07:05,560 --> 00:07:02,090
from Jill Davis Carl h12 Scott Air Force

81
00:07:07,990 --> 00:07:05,570
Base Illinois yes how many hours of

82
00:07:10,510 --> 00:07:08,000
sleep two astronauts get call it space

83
00:07:12,220 --> 00:07:10,520
is the sleep wrestle how long did your

84
00:07:15,220 --> 00:07:12,230
body's take to adjust to be a Christmas

85
00:07:17,500 --> 00:07:15,230
before being able to sleep well the

86
00:07:19,810 --> 00:07:17,510
number of hours we sleep berries just as

87
00:07:22,600 --> 00:07:19,820
it does on the ground during this side

88
00:07:26,860 --> 00:07:22,610
we've been scheduled for between six and

89
00:07:29,230 --> 00:07:26,870
eight hours of sleep and we've had to be

90
00:07:32,700 --> 00:07:29,240
so busy up here that we get that we do

91
00:07:35,710 --> 00:07:32,710
get fatigued so the sleep Israel and

92
00:08:50,530 --> 00:07:35,720
we've been able to sleep since the first

93
00:08:56,319 --> 00:08:53,319
vanished minus Houston were two minutes

94
00:08:58,540 --> 00:08:56,329
to LOL and we'll pick you up ten minutes

95
00:09:12,759 --> 00:08:58,550
later on the other side should be an

96
00:11:58,509 --> 00:09:12,769
Emmy team about 33 35 Roger that and

97
00:12:11,460 --> 00:12:00,710
Atlantis you have a go to swap to the be

98
00:12:11,470 --> 00:13:49,180
okay that's complete

99
00:13:58,250 --> 00:13:56,449
it'll an go in put the arm at the

100
00:13:59,660 --> 00:13:58,260
position for the plume attachment

101
00:14:01,280 --> 00:13:59,670
contamination experiment it kind of

102
00:14:07,430 --> 00:14:01,290
gives some interesting video if you want

103
00:14:22,780 --> 00:14:07,440
to look at that link yes we're looking

104
00:14:22,790 --> 00:14:42,809
great smiles

105
00:14:42,819 --> 00:14:48,319
lots of big smiles up here story

106
00:14:54,929 --> 00:14:52,799
sunglasses to kin story we thought you

107
00:15:03,749 --> 00:14:54,939
only had KO video through the East

108
00:15:21,290 --> 00:15:03,759
address we've got it the entire West

109
00:15:21,300 --> 00:15:46,820
that's a Louisiana smile yes it is

110
00:15:46,830 --> 00:27:15,650
Nigeria Ross

111
00:27:15,660 --> 00:27:22,360
Lane is Houston

112
00:27:29,980 --> 00:27:26,770
but you don't have the resolution y'all

113
00:27:32,770 --> 00:27:29,990
do but I see there's a coming up on a

114
00:27:39,160 --> 00:27:32,780
clear area over Canada right now I don't

115
00:27:42,370 --> 00:27:39,170
have your exact location also great like

116
00:28:24,570 --> 00:27:42,380
that is clear but I didn't want you to

117
00:28:31,770 --> 00:28:27,100
that's great-looking country we're about

118
00:28:35,530 --> 00:28:33,940
okay story and what time are you going
