00:00:03,043 --> 00:00:05,020
“HOUSTON, STATION ON SPACE TO GROUND.”

2
00:00:05,020 --> 00:00:07,880
WELCOME TO SPACE TO GROUND, I AM KAYLA LAFRANCE.

3
00:00:07,880 --> 00:00:11,330
FROM NEW ARRIVALS, AND MICROGRAVITY ARCHAEOLOGY,

4
00:00:11,330 --> 00:00:17,910
TO A SPACE WALKING DUO, THE CREW ONBOARD THE
ISS HAS HAD A BUSY WEEK.

5
00:00:17,910 --> 00:00:21,810
WITH THE ARRIVAL OF 3 COSMONAUTS TO THE ORBITING
LABORATORY LAST FRIDAY,

6
00:00:21,810 --> 00:00:26,870
THERE ARE NOW 10 PEOPLE LIVING AND WORKING
ON THE INTERNATIONAL SPACE STATION.

7
00:00:26,870 --> 00:00:32,640
THE NEWEST CREWMEMBERS LAUNCHED FROM THE BAIKONUR
COSMODROME IN KAZAKHSTAN ATOP OF A SOYUZ BOOSTER,

8
00:00:32,640 --> 00:00:36,590
THEN RENDEZVOUSED AND DOCKED WITH THE SPACE
STATION 3 HOURS LATER.

9
00:00:36,590 --> 00:00:40,970
THE TRIO WILL SPEND THE NEXT 6 AND A HALF
MONTHS PREFORMING SCIENCE AND MAINTENANCE

10
00:00:40,970 --> 00:00:42,370
ON THE ORBITING OUTPOST

11
00:00:42,370 --> 00:00:47,110
AS PART OF THE EXPEDITION 66 AND 67 CREWS.

12
00:00:47,110 --> 00:00:52,670
WHILE THE 63 SOYUZ CREW SETTLED IN THEIR NEW
HOME AND ADAPTED TO LIFE IN MICROGRAVITY,

13
00:00:52,670 --> 00:00:57,175
THE REST OF THE EXPEDITION 66 TEAM SPENT THE
WEEK PREPPING

14
00:00:57,175 --> 00:01:00,670
FOR THE SECOND SPACEWALK IN TWO WEEKS.

15
00:01:00,670 --> 00:01:04,144
SOME OF THE WORK PREFORMED BY NASA ASTRONAUT
RAJA CHARI

16
00:01:04,144 --> 00:01:07,799
AND EUROPEAN SPACE AGENCY ASTRONAUT MATTHIAS MAURER

17
00:01:07,799 --> 00:01:12,076
INCLUDED THE INSTALLATION OF JUMPER HOSES
FOR THE THERMAL SYSTEM.

18
00:01:12,076 --> 00:01:17,470
UPGRADES TO SOME OF THE ELECTRONICS AND POWER
COMPONENTS ON THE STATION WAS ALSO ON THE

19
00:01:17,470 --> 00:01:19,730
BOOKS FOR THE SPACEWALKING DUO.

20
00:01:19,730 --> 00:01:25,677
WEDNESDAY’S EVA WAS THE SECOND FOR CHARI,
AND THE FIRST FOR MAURER.

21
00:01:25,677 --> 00:01:30,340
WHEN YOU HEAR THE TERM ‘ARCHAEOLOGY’,
YOU PROBABLY THINK OF INDIANA JONES,

22
00:01:30,340 --> 00:01:33,525
EXCAVATION SITES, AND ANCIENT ARTIFACTS.

23
00:01:33,525 --> 00:01:38,780
BUT DID YOU KNOW THAT WE HAVE BEGUN DOING
ARCHEOLOGY RESEARCH IN ORBIT?

24
00:01:38,780 --> 00:01:44,890
THE ISS ARCHAEOLOGICAL PROJECT, ALSO KNOWN
AS SQUARE, IS WRAPPING UP ITS FIRST TEST STUDY

25
00:01:44,890 --> 00:01:46,891
ABOARD THE SPACE STATION.

26
00:01:46,891 --> 00:01:52,020
ARCHAEOLOGISTS ON EARTH USE A ONE METER BY
ONE METER “SHOVEL PIT” METHOD TO EXCAVATE

27
00:01:52,020 --> 00:01:54,560
LAYER BY LAYER AND REVEAL OBJECTS.

28
00:01:54,560 --> 00:02:00,930
IN SPACE, ASTRONAUTS HAVE INSTEAD TAPED OFF
ONE METER BY ONE METER SQUARES IN VARIOUS

29
00:02:00,930 --> 00:02:03,750
HIGH-TRAFFIC PLACES THROUGHOUT THEIR HOME
IN ORBIT.

30
00:02:03,750 --> 00:02:07,869
THEY’VE TAKEN PICTURES OF THOSE SQUARES
ON A DAILY BASIS TO REVEAL “LAYERS” OF

31
00:02:07,869 --> 00:02:09,525
ACTIVITY WITHIN.

32
00:02:09,525 --> 00:02:14,450
THE AIM IS TO SHOW HOW THESE AREAS CHANGE
OVER TIME AND TO CAPTURE HOW THE STATION WAS

33
00:02:14,450 --> 00:02:16,140
USED DAY-TO-DAY.

34
00:02:16,140 --> 00:02:22,040
RESULTS FROM THIS STUDY COULD NOT ONLY PRESERVE
THE DAILY USE OF THE ISS FOR FUTURE GENERATIONS,

35
00:02:22,040 --> 00:02:27,660
BUT COULD ALSO BE USED TO IMPROVE THE DESIGN
OF FUTURE SPACE CRAFT AND HABITATS.

36
00:02:27,660 --> 00:02:29,680
AND THAT’S SPACE TO GROUND FOR THIS WEEK.

37
00:02:29,680 --> 00:02:31,000
THANKS FOR WATCHING.

38
00:02:31,000 --> 00:02:36,240
BUT BEFORE WE GO, WE INVITE YOU TO LISTEN
TO “HOUSTON, WE HAVE A PODCAST”.

39
00:02:36,240 --> 00:02:40,650
THE FIRST PRIVATE ASTRONAUT MISSION TO THE
SPACE STATION IS RIGHT AROUND THE CORNER,

40
00:02:40,650 --> 00:02:46,170
AND THE UPCOMING AXIOM-1 MISSION WILL BE THE
TOPIC FOR THIS WEEK’S EPISODE.

41
00:02:46,170 --> 00:02:52,184
YOU CAN FIND THIS CONVERSATION BY GOING TO
NASA.GOV/PODCASTS.

42
00:02:52,184 --> 00:02:57,660
“HOUSTON, WE HAVE A PODCASTS”, ALONG WITH
THE FULL LIBRARY OF NASA PODCASTS ARE ALSO
