senior scientist george mcadonis

2
00:00:09,190 --> 00:00:07,510
while he works to process these blood

3
00:00:11,350 --> 00:00:09,200
samples drawn july 8th

4
00:00:13,110 --> 00:00:11,360
as close to undock as possible from

5
00:00:14,150 --> 00:00:13,120
astronauts aboard the international

6
00:00:16,710 --> 00:00:14,160
space station

7
00:00:18,070 --> 00:00:16,720
he's with nasa's human immunology and

8
00:00:20,150 --> 00:00:18,080
virology lab

9
00:00:22,630 --> 00:00:20,160
which for decades has been observing how

10
00:00:23,670 --> 00:00:22,640
space flight affects astronauts immune

11
00:00:25,910 --> 00:00:23,680
systems

12
00:00:27,910 --> 00:00:25,920
scientists want to figure out why

13
00:00:28,950 --> 00:00:27,920
because if the goal is to go into deep

14
00:00:30,870 --> 00:00:28,960
space exploration

15
00:00:32,310 --> 00:00:30,880
to go to the moon and then to mars it's

16
00:00:33,430 --> 00:00:32,320
very important that we maintain the

17
00:00:35,830 --> 00:00:33,440
health of the astronauts

18
00:00:36,790 --> 00:00:35,840
and it's important he work quickly with

19
00:00:39,190 --> 00:00:36,800
these samples

20
00:00:39,830 --> 00:00:39,200
this thin white band are the immune

21
00:00:43,350 --> 00:00:39,840
cells

22
00:00:46,069 --> 00:00:43,360
and those start to deteriorate 48 hours

23
00:00:48,549 --> 00:00:46,079
after the blood is drawn but thanks to

24
00:00:51,110 --> 00:00:48,559
spacex's redesign of its cargo dragon

25
00:00:53,430 --> 00:00:51,120
which allows for faster unloading and a

26
00:00:54,310 --> 00:00:53,440
splashdown location near nasa's kennedy

27
00:00:57,670 --> 00:00:54,320
space center

28
00:01:00,310 --> 00:00:57,680
scientists like macadonis did not

29
00:01:01,750 --> 00:01:00,320
have to wait long dragon undocked the

30
00:01:03,590 --> 00:01:01,760
morning of july 8th

31
00:01:04,950 --> 00:01:03,600
then splashed down off the coast of

32
00:01:07,830 --> 00:01:04,960
florida around 11

33
00:01:09,030 --> 00:01:07,840
30 pm july 9th a helicopter then

34
00:01:12,070 --> 00:01:09,040
delivered the more than

35
00:01:12,870 --> 00:01:12,080
5 300 pounds of cargo and science

36
00:01:15,270 --> 00:01:12,880
experiments

37
00:01:16,149 --> 00:01:15,280
to nasa's kennedy space center around 2

38
00:01:23,350 --> 00:01:16,159
50 a.m

39
00:01:27,270 --> 00:01:25,510
for those keeping score we're now at

40
00:01:30,870 --> 00:01:27,280
about 40 hours

41
00:01:32,789 --> 00:01:30,880
transportation teams moved it all

42
00:01:34,550 --> 00:01:32,799
quickly

43
00:01:36,870 --> 00:01:34,560
into the space station processing

44
00:01:39,109 --> 00:01:36,880
facility where support scientists had

45
00:01:40,950 --> 00:01:39,119
labs ready for researchers who had to

46
00:01:42,550 --> 00:01:40,960
start working on their experiments

47
00:01:44,710 --> 00:01:42,560
right away these researchers have been

48
00:01:46,550 --> 00:01:44,720
doing these studies for

49
00:01:48,630 --> 00:01:46,560
sometimes years so we want to make sure

50
00:01:49,749 --> 00:01:48,640
that we have everything set exactly as

51
00:01:51,749 --> 00:01:49,759
they need it

52
00:01:52,950 --> 00:01:51,759
in the end macadonis received the blood

53
00:01:56,310 --> 00:01:52,960
samples about

54
00:01:58,630 --> 00:01:56,320
42 hours after undock

55
00:02:00,310 --> 00:01:58,640
we left him alone so he can concentrate

56
00:02:01,990 --> 00:02:00,320
on the very critical task
