[background music]

2
00:00:01.969 --> 00:00:05.205
You have now entered the
Operations Support Room. This is

3
00:00:05.205 --> 00:00:08.509
where engineers and specialists
run tests before sending new

4
00:00:08.509 --> 00:00:11.912
updates to Hubble. This ensures
that these additions will not

5
00:00:11.912 --> 00:00:16.550
cause anything unexpected to
happen on the spacecraft. Today

6
00:00:16.550 --> 00:00:19.286
engineers are testing potential
changes to Hubble’s pointing

7
00:00:19.286 --> 00:00:23.724
control system. This room is
also used to figure out what’s

8
00:00:23.724 --> 00:00:27.527
going on when the spacecraft
isn’t operating as expected. The

9
00:00:27.527 --> 00:00:30.364
behavior could be caused by a
hardware failure, a strike from

10
00:00:30.364 --> 00:00:33.200
a high-energy particle, a
fluctuation in electrical

11
00:00:33.200 --> 00:00:37.804
current, or something else. Once
they know the cause, the team

12
00:00:37.804 --> 00:00:40.140
figures out how to get the
spacecraft back to normal

13
00:00:40.140 --> 00:00:44.778
operations. As you look around
the room, you’ll see a world map

14
00:00:44.778 --> 00:00:48.615
on the large middle screen at
the front. This shows engineers

15
00:00:48.615 --> 00:00:51.652
whether Hubble is in sunlight or
darkness, where it is with

16
00:00:51.652 --> 00:00:54.821
respect to ground stations, and
whether it is passing through a

17
00:00:54.821 --> 00:00:59.192
high-radiation zone. Another
large display on the left of the

18
00:00:59.192 --> 00:01:02.362
front wall shows a ground-based
image of what astronomical

19
00:01:02.362 --> 00:01:06.466
object Hubble is scheduled to be
looking at. This same display is

20
00:01:06.466 --> 00:01:11.772
available to anyone on NASA’s
Hubble Space Telescope website.

21
00:01:11.772 --> 00:01:14.308
In the back of the room is a
model of Hubble in the space

22
00:01:14.308 --> 00:01:17.577
shuttle cargo bay. The model
includes carriers that were

23
00:01:17.577 --> 00:01:20.080
mounted in the cargo bay to
carry new instruments,

24
00:01:20.080 --> 00:01:23.517
spacecraft components, and
astronaut tools during a

25
00:01:23.517 --> 00:01:28.288
servicing mission. In fact,
during these missions, this room

26
00:01:28.288 --> 00:01:31.858
was fully staffed 24 hours a
day, as engineers prepared

27
00:01:31.858 --> 00:00:00.000
Hubble for the installation of
new hardware.
