houston station on space to ground

2
00:00:06,389 --> 00:00:04,799
welcome to space to ground your weekly

3
00:00:08,150 --> 00:00:06,399
look at what's happening on board the

4
00:00:10,150 --> 00:00:08,160
international space station i'm dan

5
00:00:11,990 --> 00:00:10,160
hewitt a new cargo ship launched

6
00:00:15,030 --> 00:00:12,000
successfully this week with a several

7
00:00:17,189 --> 00:00:15,040
ton shipment on board the fifth japanese

8
00:00:20,070 --> 00:00:17,199
htv lifted off on wednesday and made it

9
00:00:21,990 --> 00:00:20,080
to orbit in just 15 minutes the unmanned

10
00:00:23,990 --> 00:00:22,000
ship is packed with over four and a half

11
00:00:26,070 --> 00:00:24,000
tons of equipment and supplies for the

12
00:00:28,470 --> 00:00:26,080
station crew and is even carrying what

13
00:00:30,870 --> 00:00:28,480
will be the new iss kitchen it's

14
00:00:32,870 --> 00:00:30,880
scheduled to arrive on august 24th which

15
00:00:35,590 --> 00:00:32,880
you can watch live by checking out

16
00:00:37,990 --> 00:00:35,600
nasa.gov ntv

17
00:00:39,590 --> 00:00:38,000
and onboard htv is a new experiment

18
00:00:42,069 --> 00:00:39,600
that's going to try and unlock some of

19
00:00:44,470 --> 00:00:42,079
the great mysteries of the universe the

20
00:00:46,709 --> 00:00:44,480
calorimetric electron telescope or

21
00:00:48,470 --> 00:00:46,719
calais will be searching for signatures

22
00:00:50,950 --> 00:00:48,480
of dark matter one of the biggest

23
00:00:53,110 --> 00:00:50,960
question marks in modern astrophysics

24
00:00:54,790 --> 00:00:53,120
the japanese experiment will be exposed

25
00:00:57,029 --> 00:00:54,800
to space and measure high energy

26
00:00:59,189 --> 00:00:57,039
particles hopefully providing clues to

27
00:01:01,029 --> 00:00:59,199
things like the origin of cosmic rays

28
00:01:03,029 --> 00:01:01,039
and the existence of dark matter

29
00:01:05,509 --> 00:01:03,039
important steps in better understanding

30
00:01:07,670 --> 00:01:05,519
our solar system and beyond

31
00:01:09,910 --> 00:01:07,680
we received a lot of questions asking if

32
00:01:11,990 --> 00:01:09,920
the perseid meteor shower was affecting

33
00:01:13,830 --> 00:01:12,000
the station at all and if the astronauts

34
00:01:16,070 --> 00:01:13,840
could see it well fortunately the

35
00:01:17,910 --> 00:01:16,080
station isn't in any danger during such

36
00:01:19,270 --> 00:01:17,920
events and they did manage to get a

37
00:01:21,429 --> 00:01:19,280
quick glimpse

38
00:01:23,429 --> 00:01:21,439
most of the material in a meteor shower

39
00:01:25,510 --> 00:01:23,439
is made up of dust and very tiny

40
00:01:27,910 --> 00:01:25,520
particles that the station is protected

41
00:01:30,310 --> 00:01:27,920
from by tough shielding the only extra

42
00:01:32,469 --> 00:01:30,320
precaution we take is no spacewalks when

43
00:01:33,670 --> 00:01:32,479
flying through as spacesuits are more

44
00:01:35,590 --> 00:01:33,680
vulnerable

45
00:01:37,590 --> 00:01:35,600
and astronaut scott kelly only managed

46
00:01:39,270 --> 00:01:37,600
to get one shot of a meteor streaking

47
00:01:40,789 --> 00:01:39,280
through the earth's atmosphere but was

48
00:01:43,749 --> 00:01:40,799
quick to remind us that the view is

49
00:01:45,190 --> 00:01:43,759
spectacular no matter what

50
00:01:47,030 --> 00:01:45,200
