00:00:00,080 --> 00:00:03,440
A commercial mission returning 
cargo from the space station …
  

2
00:00:03,440 --> 00:00:08,560
The first space station spacewalk of the year …
 
And observing a massive volcanic eruption  

3
00:00:08,560 --> 00:00:12,320
from space … a few of the stories to 
tell you about – This Week at NASA!
  

4
00:00:14,080 --> 00:00:19,440
A SpaceX Dragon cargo resupply spacecraft is 
slated to return to Earth from the International  

5
00:00:19,440 --> 00:00:25,200
Space Station loaded with more than 4,900 
pounds of cargo, including supplies and an  

6
00:00:25,200 --> 00:00:31,680
array of microgravity scientific experiments. 
The Dragon’s return will cap off SpaceX’s 24th  

7
00:00:31,680 --> 00:00:38,320
Commercial Resupply Services mission for NASA.
 
On Jan. 19 two Russian cosmonauts ventured outside  

8
00:00:38,320 --> 00:00:42,320
the International Space Station to conduct 
the station’s first spacewalk of the year.  

9
00:00:42,880 --> 00:00:49,040
During the outing, Anton Shkaplerov and Pyotr 
Dubrov of Roscosmos performed work to prepare  

10
00:00:49,040 --> 00:00:55,360
the new Prichal docking module for future Russian 
visiting spacecraft. The first docking to Prichal  

11
00:00:55,360 --> 00:01:00,640
is targeted for March, with the arrival of 
three cosmonauts aboard a Soyuz spacecraft.
  

12
00:01:01,360 --> 00:01:06,720
Several Earth-observing satellites are helping 
scientists affiliated with NASA’s Disasters  

13
00:01:06,720 --> 00:01:12,800
programcollect and share data from the massive 
volcanic eruption that obliterated the small,  

14
00:01:12,800 --> 00:01:19,120
uninhabited South Pacific island known as Hunga 
Tonga-Hunga Ha‘apai. Damage assessments are  

15
00:01:19,120 --> 00:01:24,400
ongoing, but preliminary reports indicate that 
populated communities in the island nation of  

16
00:01:24,400 --> 00:01:30,400
Tonga have taken heavy damage from volcanic 
ash and a tsunami caused by the eruption.
  

17
00:01:31,040 --> 00:01:36,240
Engineers at our Stennis Space Center conducted 
the first RS-25 engine hot fire test of the  

18
00:01:36,240 --> 00:01:44,000
new year on Jan. 19. Four RS-25s will help 
power our Space Launch System or (SLS) rocket  

19
00:01:44,000 --> 00:01:49,520
on future deep-space missions, including this 
year’s uncrewed Artemis I mission around the Moon.  

20
00:01:49,520 --> 00:01:54,960
This was the second overall test in the current 
test series which began in mid-December.  

21
00:01:54,960 --> 00:01:59,200
Each test provides valuable data that 
can be used to help develop the engines.
  

22
00:02:00,000 --> 00:02:05,280
The team assembling our X-59 Quiet SuperSonic 
Technology (QueSST) aircraft is making great  

23
00:02:05,280 --> 00:02:10,320
progress with the developmental X-plane. 
The crew successfully added the tail,  

24
00:02:10,320 --> 00:02:14,800
attached and tested out the positioning of 
the nose, performed a system check of the  

25
00:02:14,800 --> 00:02:21,280
ejection seat, and moved the X-59’s 
GE F414 engine to facilitate a 3D  

26
00:02:21,280 --> 00:02:28,000
engine scan. This scan helps engineers better 
understand the F414’s fit in the engine bay.  

27
00:02:28,000 --> 00:02:33,520
The X-59 is being built to conduct research 
aimed at reducing the loudness of sonic booms  

28
00:02:33,520 --> 00:02:39,120
that can occur during supersonic flight.
