1
00:00:03,149 --> 00:00:05,600
WELCOME TO SPACE TO GROUND, I’M LEAH CHESHIER.

2
00:00:05,600 --> 00:00:10,470
COMING UP SOON, THE CYGNUS SPACECRAFT WILL
ASCEND TO ITS NEW PLACE IN SPACE AFTER RIDING

3
00:00:10,470 --> 00:00:11,740
AN ANTARES ROCKET.

4
00:00:13,100 --> 00:00:15,560
NORTHROP GRUMMAN’S CYGNUS RESUPPLY SPACECRAFT IS SCHEDULE

5
00:00:15,560 --> 00:00:18,020
TO LAUNCH FRIDAY AFTERNOON, FEBRUARY 14

6
00:00:18,020 --> 00:00:21,700
FROM THE MID-ATLANTIC REGIONAL SPACEPORT IN
WALLOPS ISLAND, VIRGINIA,

7
00:00:21,700 --> 00:00:24,060
BOUND FOR THE INTERNATIONAL SPACE STATION.

8
00:00:24,070 --> 00:00:28,880
THIS CYGNUS, LAUNCHING DURING BLACK HISTORY
MONTH, IS NAMED THE “SS ROBERT H. LAWRENCE”

9
00:00:28,880 --> 00:00:32,579
IN HONOR OF THE FIRST AFRICAN AMERICAN TO
BE SELECTED AS AN ASTRONAUT.

10
00:00:32,579 --> 00:00:38,500
THE COMPANY’S 13TH RESUPPLY MISSION WILL
DELIVER OVER 7,500 POUNDS OF CREW SUPPLIES,

11
00:00:38,500 --> 00:00:42,290
RESEARCH INVESTIGATIONS, SPACEWALK EQUIPMENT
AND MORE.

12
00:00:42,290 --> 00:00:44,800
CYGNUS WILL ARRIVE AT THE STATION ON FEBRUARY 16,

13
00:00:44,800 --> 00:00:48,370
WHERE NASA ASTRONAUT JESSICA MEIR WILL MONITOR ITS APPROACH AND RENDEZVOUS

14
00:00:48,370 --> 00:00:52,960
BEFORE IT IS CAPTURED BY THE CANADARM2, CONTROLLED BY ANDREW MORGAN.

15
00:00:53,740 --> 00:00:56,240
AS WE PLAN TO VENTURE FURTHER INTO SPACE,

16
00:00:56,240 --> 00:01:01,580
WE KNOW THAT INCREASED EXPOSURE TO RADIATION
IN SPACE CAN POSE HEALTH HAZARDS FOR ASTRONAUTS.

17
00:01:01,580 --> 00:01:05,200
RESEARCH ON THE SPACE STATION MIGHT HELP US
PREPARE FOR THOSE LONGER JOURNEYS.

18
00:01:06,340 --> 00:01:09,900
ASTRONAUT LONG-TERM HEALTH CAN BE AFFECTED
AS RADIATION MAY CAUSE

19
00:01:09,900 --> 00:01:12,300
DOUBLE-STRAND BREAKS IN THEIR DNA.

20
00:01:12,300 --> 00:01:15,080
CELLS REPAIR THESE BREAKS, BUT NOT ALWAYS
PERFECTLY,

21
00:01:15,080 --> 00:01:18,940
AND THE ERRORS MAY RESULT IN DETRIMENTAL EFFECTS, LIKE CANCER.

22
00:01:18,940 --> 00:01:23,760
THE GENES IN SPACE-6 EXPERIMENT DETERMINES
THE OPTIMAL DNA REPAIR MECHANISMS THAT CELLS

23
00:01:23,760 --> 00:01:25,890
USE IN A SPACEFLIGHT ENVIRONMENT.

24
00:01:25,890 --> 00:01:31,880
FOR THE FIRST TIME, THE ENTIRE DNA DAMAGE,
MUTATION AND REPAIR PROCESS IS BEING EVALUATED

25
00:01:31,880 --> 00:01:34,500
IN SPACE AT THE MOLEULAR LEVEL.

26
00:01:34,500 --> 00:01:37,820
NOT ONLY WILL THIS RESEARCH HELP US PREPARE
FOR LONG DURATION MISSIONS

27
00:01:37,820 --> 00:01:39,340
TO THE MOON AND MARS,

28
00:01:39,340 --> 00:01:44,480
IT ALSO MAY HELP DEVELOP PROCEDURES TO PROTECT PEOPLE IN REMOTE AND HARSH LOCATIONS ON EARTH.

29
00:01:45,060 --> 00:01:48,780
THIS WEEK, WE’RE HIGHLIGHTING JUST A FEW
OF THE THOUSANDS OF MESSAGES WE RECEIVED

30
00:01:48,780 --> 00:01:50,980
WITH THE HASHTAG #CONGRATSCHRISTINA

31
00:01:50,980 --> 00:01:55,720
AFTER NASA ASTRONAUT CHRISTINA KOCH COMPLETED A 328 DAY MISSION

32
00:01:55,720 --> 00:02:00,740
TO THE INTERNATIONAL SPACE STATION, THE LONGEST SINGLE DURATION MISSION FOR A WOMAN.

33
00:02:00,740 --> 00:02:06,180
EZEKIEL SENT HIS CONGRATULATIONS, BUT ADMITTED
HE WOULD MISS SEEING CHRISTINA’S SPACE HAIR.

34
00:02:06,180 --> 00:02:10,560
EVAN RECALLED WATCHING THE FIRST ALL WOMAN
SPACEWALK DURING WHICH CHRISTINA AND JESSICA

35
00:02:10,560 --> 00:02:13,409
MEIR VENTURED OUTSIDE THE STATION IN OCTOBER.

36
00:02:13,409 --> 00:02:17,940
JJHOFAN SAID THEY LET THEIR 11 YEAR OLD STAY
UP TOO LATE TO WATCH THE LANDING,

37
00:02:17,940 --> 00:02:20,340
BUT WE THINK IT WAS WORTH IT.

38
00:02:20,340 --> 00:02:24,500
PRIOR TO BECOMING AN ASTRONAUT, CHRISTINA
CONDUCTED REMOTE SCIENTIFIC FIELD WORK AT

39
00:02:24,500 --> 00:02:26,209
PALMER STATION IN ANTARCTICA,

40
00:02:26,209 --> 00:02:29,240
WHO SENT THEIR CONGRATS MESSAGE WHLE WATCHING HER LANDING.

41
00:02:29,640 --> 00:02:32,440
"BON VOYAGE, CHRISTINA!"
