00:00:08,150 --> 00:00:06,240
next stop planet earth

00:00:10,310 --> 00:00:08,160
welcome to space to ground i'm dan

00:00:12,549 --> 00:00:10,320
hewitt just over one month after

5
00:00:15,749 --> 00:00:12,559
arriving at the station it was time for

6
00:00:19,029 --> 00:00:15,759
spacex's eighth dragon to return

7
00:00:21,269 --> 00:00:19,039
after packing over 3 700 pounds of cargo

8
00:00:23,189 --> 00:00:21,279
into the capsule the crew said farewell

00:00:25,269 --> 00:00:23,199
to dragon on wednesday

10
00:00:27,509 --> 00:00:25,279
british astronaut tim peake sent the

11
00:00:29,830 --> 00:00:27,519
command for the station's robotic arm to

12
00:00:32,310 --> 00:00:29,840
release the cargo craft which then flew

13
00:00:34,310 --> 00:00:32,320
away to set up for re-entry

14
00:00:36,790 --> 00:00:34,320
dragons splashed down in the pacific

15
00:00:38,790 --> 00:00:36,800
ocean to the southwest of california

16
00:00:40,790 --> 00:00:38,800
where teams from spacex were ready to

17
00:00:43,350 --> 00:00:40,800
pluck it out of the water and begin

18
00:00:45,110 --> 00:00:43,360
unloading the cargo on board

19
00:00:47,110 --> 00:00:45,120
the one-year mission may have ended in

20
00:00:50,069 --> 00:00:47,120
march but a lot of the science samples

21
00:00:53,510 --> 00:00:50,079
are just now making their way to earth

22
00:00:57,270 --> 00:00:53,520
more than 1 000 samples of blood urine

23
00:00:59,590 --> 00:00:57,280
saliva and more from scott kelly's 340

24
00:01:02,150 --> 00:00:59,600
days in space splashed down with the

25
00:01:04,390 --> 00:01:02,160
cargo inside dragon this week

26
00:01:07,429 --> 00:01:04,400
supporting different studies like fluid

27
00:01:09,670 --> 00:01:07,439
shifts microbiome the twin study and

28
00:01:11,830 --> 00:01:09,680
more these samples are now on their way

29
00:01:13,190 --> 00:01:11,840
to researchers around the country for

30
00:01:14,950 --> 00:01:13,200
analysis

31
00:01:16,789 --> 00:01:14,960
results from the year-long mission will

32
00:01:19,270 --> 00:01:16,799
provide new knowledge about how the

33
00:01:21,670 --> 00:01:19,280
human body adapts over a long time in

34
00:01:23,590 --> 00:01:21,680
space critical for preparing the first

35
00:01:25,590 --> 00:01:23,600
trips to mars

36
00:01:27,670 --> 00:01:25,600
this week steven asked if we could show

37
00:01:30,870 --> 00:01:27,680
off views of stars from the station's

38
00:01:33,190 --> 00:01:30,880
cupola no problem stephen

39
00:01:35,830 --> 00:01:33,200
over the past few years astronauts have

40
00:01:38,310 --> 00:01:35,840
taken a number of stunning sequences of

41
00:01:40,550 --> 00:01:38,320
stars and the milky way while orbiting

42
00:01:42,550 --> 00:01:40,560
the dark side of the earth from the

43
00:01:44,230 --> 00:01:42,560
windowed vantage point of the cupola

44
00:01:46,469 --> 00:01:44,240
they're treated to some of the best

45
00:01:48,550 --> 00:01:46,479
light shows in the galaxy

46
00:01:50,230 --> 00:01:48,560
you can see these videos and a whole lot

47
00:01:52,510 --> 00:01:50,240
