2
00:00:02,986 --> 00:00:04,976
WELCOME TO SPACE TO
GROUND, I'M GARY JORDAN.

3
00:00:05,260 --> 00:00:07,360

I AM DEEPLY HONORED SO
THANK YOU ALL SO MUCH."

22
00:00:55,426 --> 00:00:56,886
LOTS OF SCIENCE ON
BOARD THIS WEEK,

23
00:00:57,026 --> 00:00:59,786
BUT ONE STANDS OUT AS THE MVP.

24
00:01:00,166 --> 00:01:03,096
NASA ASTRONAUT DREW FEUSTEL
INSERTED FOOD CYLINDERS

25
00:01:03,096 --> 00:01:06,606
IN THE MULTI-USE
VARIABLE-G PLATFORM, OR MVP.

26
00:01:06,726 --> 00:01:09,736
MVP IS A FACILITY THAT
SUBJECTS MANY TYPES OF SAMPLES

27
00:01:09,776 --> 00:01:13,406
LIKE FRUIT FLIES, FLATWORMS,
PLANTS, FISH, CELLS,

28
00:01:13,706 --> 00:01:15,766
PROTEIN CRYSTALS, AND
IN THIS CASE FOOD,

29
00:01:16,176 --> 00:01:17,176
TO ARTIFICIAL GRAVITY.

30
00:01:17,576 --> 00:01:19,786
THE PLATFORM HAS 2
INTERNAL CAROUSELS

31
00:01:19,786 --> 00:01:22,266
THAT CAN SIMULTANEOUSLY
PRODUCE UP TO 2 GS.

32
00:01:22,676 --> 00:01:25,256
ON EARTH, WE'RE ALL STUCK WITH
1 G NO MATTER WHERE WE GO.

33
00:01:25,706 --> 00:01:28,566
THE INTERNATIONAL SPACE STATION
IS THE ONLY RESEARCH FACILITY

34
00:01:28,566 --> 00:01:31,496
WHERE GRAVITY CAN BE A VARIABLE
LONG TERM FOR EXPERIMENTS.

35
00:01:32,336 --> 00:01:33,936
THIS WEEK'S QUESTIONS
COMES FROM CONG,

36
00:01:34,296 --> 00:01:35,966
WHO WANTS TO KNOW
WHAT COLOR THE SUN IS

37
00:01:35,966 --> 00:01:37,486
FROM AN ASTRONAUT'S PERSPECTIVE.

38
00:01:37,806 --> 00:01:39,006
WITHOUT THE ATMOSTPHERE
IN THE WAY,

39
00:01:39,076 --> 00:01:40,686
THE SUN ACTUALLY APPEARS WHITE.

40
00:01:41,536 --> 00:01:43,626
HAVE YOU EVER THOUGHT ABOUT
HOW THE SUN IS NEVER REALLY A

41
00:01:43,626 --> 00:01:44,516
CONSISTENT COLOR?

42
00:01:45,026 --> 00:01:46,956
IT'S ESPECIALLY NOTICIABLE
AT SUNSET

43
00:01:47,146 --> 00:01:48,906
WHERE THE SUN CAN
BE YELLOW, ORANGE,

44
00:01:49,096 --> 00:01:50,416
EVEN SOMETIMES A LITTLE RED.

45
00:01:50,866 --> 00:01:53,276
THIS IS ACTUALLY SHORTER
WAVELENGTHS OF VISIBLE LIGHT,

46
00:01:53,606 --> 00:01:56,776
YOUR GREENS, BLUES AND VIOLENTS,
SCATTERING AS THEY PASS

47
00:01:56,816 --> 00:01:57,546
THROUGH THE ATMOSPHERE.

48
00:01:57,686 --> 00:02:00,596
FROM THE SPACE STATION, MUCH OF
THE ATMOSPHERE ISN'T IN THE WAY

49
00:02:00,596 --> 00:02:01,856
TO SCATTER LIGHT FROM THE SUN,

50
00:02:02,096 --> 00:02:04,926
SO THE FULL VISIBLE SPECTRUM
COMES THROUGH AS A BRIGHT WHITE.

51
00:02:05,596 --> 00:02:07,326
ASTRONAUTS HAVE CAPTURED
MANY IMAGES

52
00:02:07,326 --> 00:02:08,506
OF THE WHITE SUN FROM SPACE.

53
00:02:08,876 --> 00:02:12,086
WITH 16 SUNRISES AND SUNSETS
PER DAY ON THE SPACE STATION,

54
00:02:12,346 --> 00:02:14,536
THERE ARE TIMES WHERE THE
ASTRONAUTS CAN CAPTURE THE SUN

55
00:02:14,536 --> 00:02:17,156
AGAINST THE HORIZON WHERE
LIGHT IS SCATTERED THE SAME

56
00:02:17,156 --> 00:02:20,646
AS A SUNSET ON EARTH, CREATING
BEAUTIFULLY COLORED SUNSETS EVEN

57
00:02:20,646 --> 00:02:22,916
FROM 250 MILES ABOVE THE PLANET.
