1
00:00:01,000 --> 00:00:02,600
"Houston, Station on Space to Ground".

2
00:00:04,180 --> 00:00:05,970
FLYING ROBOTS IN SPACE...

3
00:00:05,970 --> 00:00:07,190
WHAT ELSE COULD YOU WANT?

4
00:00:08,236 --> 00:00:10,436
WELCOME TO SPACE TO
GROUND, I'M DAN HUOT.

5
00:00:10,766 --> 00:00:12,686
THE SPHERES SATELLITES
WERE ZOOMING

6
00:00:12,686 --> 00:00:14,906
AROUND THE STATION
ONCE AGAIN THIS WEEK.

7
00:00:15,486 --> 00:00:19,316
THE SYNCHRONIZED POSITION,
HOLD, ENGAGE, REORIENT,

8
00:00:19,316 --> 00:00:22,636
EXPERIMENTAL SATELLITES, OR
SPHERES, WERE PUT TO WORK

9
00:00:22,636 --> 00:00:25,606
WITH A NEW UNIVERSAL
DOCKING PORT ATTACHMENT.

10
00:00:25,826 --> 00:00:28,266
WITH THEIR NEW DOCKING
AND UNDOCKING ABILITY,

11
00:00:28,266 --> 00:00:31,626
THEY SERVED AS A TEST CASE
FOR THE CHALLENGES OF FLYING

12
00:00:31,626 --> 00:00:33,746
AND CONNECTING AUTONOMOUS
SPACECRAFT.

13
00:00:34,346 --> 00:00:36,256
LESSONS LEARNED FROM
INVESTIGATIONS

14
00:00:36,256 --> 00:00:39,786
LIKE THIS COULD LEAD TO ROBOTIC
SATELLITES PERFORMING COMPLEX

15
00:00:39,826 --> 00:00:42,886
WORK IN OUTER SPACE ALL
ON THEIR OWN, DOING THINGS

16
00:00:42,886 --> 00:00:44,416
LIKE ASSEMBLING SPACECRAFT,

17
00:00:44,556 --> 00:00:47,576
REPAIRING OTHER SATELLITES
OR REFUELING THEM.

18
00:00:47,766 --> 00:00:51,306
WE COULD ALSO APPLY LESSONS FROM
THE SPHERES RIGHT HERE ON EARTH,

19
00:00:51,506 --> 00:00:53,936
SPECIFICALLY DEEP
UNDERWATER IN MISSIONS

20
00:00:53,936 --> 00:00:55,916
TO AN UNCHARTED OCEAN FLOOR.

21
00:00:56,840 --> 00:00:59,240
THE SPRING TRAFFIC SEASON
IS ABOUT TO KICK OFF

22
00:00:59,296 --> 00:01:01,996
WITH SPACEX'S TENTH
RESUPPLY MISSION.

23
00:01:02,486 --> 00:01:05,326
AN UNMANNED DRAGON
CARGO CRAFT IS TARGETED

24
00:01:05,326 --> 00:01:07,760
TO LAUNCH ON SATURDAY, FEBRUARY 18th

25
00:01:07,760 --> 00:01:10,260
AT 10:01 A.M. EASTERN TIME.

26
00:01:10,586 --> 00:01:14,526
PACKED WITH NEARLY 5,500
POUNDS OF SCIENCE AND SUPPLIES,

27
00:01:14,736 --> 00:01:18,336
IT'S SET TO LAUNCH FROM
PAD 39A, THE SAME PAD

28
00:01:18,336 --> 00:01:21,086
THAT FIRST SENT HUMANS TO
THE MOON AND WAS THE SITE

29
00:01:21,156 --> 00:01:23,006
FOR THE FINAL FLIGHT
OF THE SPACE SHUTTLE.

30
00:01:23,616 --> 00:01:26,136
ONBOARD, THE CREW HAS BEEN
TRAINING FOR THEIR ROLE

31
00:01:26,136 --> 00:01:28,656
OF CAPTURING DRAGON ONCE
IT ARRIVES ON MONDAY.

32
00:01:29,166 --> 00:01:32,226
YOU CAN WATCH DRAGON'S
JOURNEY LIVE ON NASA TV

33
00:01:32,276 --> 00:01:35,546
OR BY GOING TO NASA.GOV/NTV.

34
00:01:36,286 --> 00:01:39,196
OUR VIEWER QUESTION THIS
WEEK COMES FROM ZACK HANSEN

35
00:01:39,196 --> 00:01:42,786
IN MR. TELLSTROM'S 4TH GRADE
CLASS AT SUNRISE ELEMENTARY.

36
00:01:43,226 --> 00:01:46,036
ZACK WANTED TO KNOW HOW MUCH
ELECTRICITY GETS COLLECTED

37
00:01:46,036 --> 00:01:47,116
IN THE SOLAR PANELS.

38
00:01:47,536 --> 00:01:49,846
THEY'RE BIG SOLAR
ARRAYS, SO IT'S A LOT.

39
00:01:50,596 --> 00:01:54,276
ON AVERAGE, THE MASSIVE
ARRAYS GENERATE 75 KW

40
00:01:54,276 --> 00:01:57,456
OF CONTINUOUS POWER,
ENOUGH TO POWER DOZENS

41
00:01:57,456 --> 00:01:58,606
OF HOMES HERE ON EARTH.

42
00:01:59,096 --> 00:02:02,996
TWO BLANKETS OF SOLAR CELLS
MAKE UP EACH SOLAR ARRAY WING

43
00:02:03,196 --> 00:02:05,086
WITH 8 WINGS TOTAL
ON THE STATION.

44
00:02:05,496 --> 00:02:08,206
EACH WING WEIGHS MORE
THAN 2,400 POUNDS

45
00:02:08,456 --> 00:02:12,346
AND USES 32,800 SOLAR
ARRAY CELLS.

46
00:02:12,966 --> 00:02:15,566
IT SOUNDS LIKE A LOT,
BUT THESE PROVIDE ALL

47
00:02:15,566 --> 00:02:19,136
OF THE ELECTRICAL POWER FOR THE
STATION, ENERGIZING EVERYTHING

48
00:02:19,196 --> 00:02:21,946
FROM THE LIGHTS AND EXPERIMENTS
TO THE AIR GENERATORS

49
00:02:21,946 --> 00:02:24,496
AND LIFE SUPPORT SYSTEMS
KEEPING THE CREW SAFE

50
00:02:24,496 --> 00:02:26,396
AND FUNCTIONING IN OUTER SPACE.

51
00:02:27,356 --> 00:02:30,006
KEEP SENDING YOUR
QUESTIONS USING THE HASHTAG
