00:00:11,560 --> 00:00:14,700
Preparations for the last servicing 
mission to the Hubble Space Telescope

5
00:00:14,700 --> 00:00:21,000
are well underway at several NASA facilities. 
Almost all 22 thousand pounds of

6
00:00:21,000 --> 00:00:24,869
Service Mission 4 hardware is at some 
stage of integration and test at the

7
00:00:24,869 --> 00:00:31,500
Goddard Space Flight Center in Maryland. 
This includes, new gyros, batteries, fine

8
00:00:31,500 --> 00:00:38,790
guidance sensor, astronaut tools, support hardware, 
a new docking ring, the carrier

9
00:00:38,790 --> 00:00:44,010
systems and 2 new Hubble science instruments. 
The Wide Field Camera 3

10
00:00:44,010 --> 00:00:48,180
begins its 3rd and final thermal vacuum 
test shortly, where it will

11
00:00:48,180 --> 00:00:53,699
experience the harshness of space inside a large 
simulator for several weeks.

12
00:00:53,699 --> 00:00:57,330
The Service Mission 4 astronauts come 
to Goddard to practice installing the

13
00:00:57,330 --> 00:01:02,040
camera into the Hubble Space Telescope 
high-fidelity mechanical simulator as

14
00:01:02,040 --> 00:01:05,820
well as the carrier systems that will 
transport the camera to orbit onboard

15
00:01:05,820 --> 00:01:10,760
the space shuttle. The Wide Field Camera 3 
will be Hubble's most advanced camera,

16
00:01:10,760 --> 00:01:16,260
increasing it's discovery efficiency by a factor of 5. 
The Cosmic Origins

17
00:01:16,260 --> 00:01:20,790
Spectrograph, a point-source ultra-violet 
spectrograph, is ready for

18
00:01:20,790 --> 00:01:25,860
flight. Astronauts practice installing COS 
into the high-fidelity mechanical

19
00:01:25,860 --> 00:01:28,120
simulator and the carrier systems.

21
00:01:31,220 --> 00:01:36,000
At Goddard, engineers and astronauts 
work together developing tools and techniques

22
00:01:36,000 --> 00:01:40,170
to resurrect 2 malfunctioning science 
instruments currently on orbit inside

23
00:01:40,170 --> 00:01:45,659
Hubble. Both the Space Telescope Imaging 
Spectrograph and the Advanced Camera for

24
00:01:45,659 --> 00:01:50,700
Surveys suffered power supply failures. 
This is the first time a repair like

25
00:01:50,700 --> 00:01:57,570
this has ever been done on orbit. One of 
NASA's premier training facilities at

26
00:01:57,570 --> 00:02:02,580
the Johnson Space Center in Houston, 
is the Neutral Buoyancy Laboratory. In this

27
00:02:02,580 --> 00:02:07,950
6.2 million gallon swimming pool, Goddard 
engineers work along side the astronauts

28
00:02:07,950 --> 00:02:09,760
as they train for the mission.

00:02:13,120 --> 00:02:15,720
Scientists and engineers
are excited about flying

31
00:02:15,720 --> 00:02:19,470
this last servicing mission to the 
Hubble Space Telescope and, we'll update

32
00:02:19,470 --> 00:02:22,620
you periodically as preparations continue.
