“Here’s some of the stories trending This
Week at NASA!”

2
00:00:04,020 --> 00:00:10,340
A Jan. 26 event at NASA’s Michoud Assembly
Facility in New Orleans, marked recently completed

3
00:00:10,340 --> 00:00:15,480
work by technicians there to weld together
the pressure vessel for the next Orion deep

4
00:00:15,480 --> 00:00:17,310
space crew module.

5
00:00:17,310 --> 00:00:21,900
The event also was an opportunity for NASA
officials to thank employees and to show the

6
00:00:21,900 --> 00:00:27,360
progress on Orion and the core stage of the
agency’s Space Launch System (SLS) rocket.

7
00:00:27,360 --> 00:00:31,900
The Orion pressure vessel will be shipped
to Kennedy Space Center in Florida next month,

8
00:00:31,900 --> 00:00:37,750
where engineers will continue to prepare it
for the first flight of the SLS rocket.

9
00:00:37,750 --> 00:00:43,190
Even as the one-year mission aboard the International
Space Station winds down, activity continues

10
00:00:43,190 --> 00:00:46,070
at a steady clip on the orbital laboratory.

11
00:00:46,070 --> 00:00:50,600
This week, those activities included an altitude
correction in advance of the landing in early

12
00:00:50,600 --> 00:00:56,430
March of Expedition 46 – including one-year
crew members Scott Kelly of NASA and Russia’s

13
00:00:56,430 --> 00:01:02,149
Mikhail Kornienko, work by Kelly and Flight
Engineer Tim Peake to prepare for a nanosatellite

14
00:01:02,149 --> 00:01:08,110
deployment, and NASA astronaut Tim Kopra continued
work with a fire studies experiment.

15
00:01:08,110 --> 00:01:13,080
The crew also is preparing for a Russian spacewalk
on Feb. 3.

16
00:01:13,080 --> 00:01:18,970
A new color animation, based on images from
NASA's Dawn spacecraft, shows a simulated

17
00:01:18,970 --> 00:01:22,120
flight over the surface of dwarf planet Ceres.

18
00:01:22,120 --> 00:01:26,830
The enhanced color movie highlights variations
in the appearance of surface materials and

19
00:01:26,830 --> 00:01:30,390
helps emphasize the most prominent craters
on Ceres.

20
00:01:30,390 --> 00:01:35,470
Dawn is the first mission to visit Ceres,
the largest object in the main asteroid belt

21
00:01:35,470 --> 00:01:37,360
between Mars and Jupiter.

22
00:01:37,360 --> 00:01:42,170
The spacecraft is in its final and lowest
mapping orbit, at about 240 miles from the

23
00:01:42,170 --> 00:01:44,510
surface.

24
00:01:44,510 --> 00:01:50,420
Jan. 28 was NASA’s Day of Remembrance and
the 30th anniversary of the space shuttle

25
00:01:50,420 --> 00:01:52,479
Challenger accident.

26
00:01:52,479 --> 00:01:57,450
During the annual Day of Remembrance, the
agency pays tribute to the crews of Apollo

27
00:01:57,450 --> 00:02:04,939
1, Challenger and space shuttle Columbia,
as well as other members of the NASA family

28
00:02:04,939 --> 00:02:10,160
who lost their lives while furthering the
cause of exploration and discovery.

29
00:02:10,160 --> 00:02:15,480
NASA Administrator Charlie Bolden, Deputy
Administrator Dava Newman, and other agency

30
00:02:15,480 --> 00:02:20,529
senior officials participated in a wreath-laying
observance at Arlington National Cemetery

31
00:02:20,529 --> 00:02:22,359
in Virginia.

32
00:02:22,359 --> 00:02:27,489
Similar observances took place at the Kennedy
Space Center, Johnson Space Center and other

33
00:02:27,489 --> 00:02:28,969
centers around the agency.

34
00:02:28,969 --> 00:02:32,129
And that’s what’s up this week @NASA …
