00:00:01.368 --> 00:00:03.737
You are now in the exhibit
hallway outside of the

3
00:00:03.737 --> 00:00:06.707
Operations Support Room, which
displays some of the hardware

4
00:00:06.707 --> 00:00:10.477
that once flew on Hubble. In the
built-in display case you see a

5
00:00:10.477 --> 00:00:15.082
black electronic control box. It
was used to control gyroscopes -

6
00:00:15.082 --> 00:00:17.584
the sensors that can tell how
fast Hubble is turning and in

7
00:00:17.584 --> 00:00:21.688
what direction. During the first
servicing mission in 1993,

8
00:00:21.688 --> 00:00:25.125
astronauts replaced this control
box and learned that it had a

9
00:00:25.125 --> 00:00:29.096
bad capacitor. It was fixed so
that it could potentially be

10
00:00:29.096 --> 00:00:33.934
used on Hubble again, but it was
never needed. Farther over is

11
00:00:33.934 --> 00:00:36.203
one of the original tape
recorders used for storing

12
00:00:36.203 --> 00:00:39.373
science and engineering data.
During the second servicing

13
00:00:39.373 --> 00:00:43.010
mission in 1997, the tape
recorder was replaced with a

14
00:00:43.010 --> 00:00:46.813
solid state recorder, similar to
a USB memory stick, which could

15
00:00:46.813 --> 00:00:50.417
hold 10 times more information.
This was important as Hubble

16
00:00:50.417 --> 00:00:52.986
would later be upgraded with
better cameras that had over six

17
00:00:52.986 --> 00:00:57.925
times the resolution – requiring
more storage space. On the

18
00:00:57.925 --> 00:01:01.561
opposite wall, standalone
display cases contain tools

19
00:01:01.561 --> 00:01:05.165
developed to help astronauts
work on Hubble. The Mini Power

20
00:01:05.165 --> 00:01:08.769
Tool is a power screwdriver with
LED lights and interchangeable

21
00:01:08.769 --> 00:01:12.506
screwdriver bits. It is
connected to a battery pack so

22
00:01:12.506 --> 00:01:16.710
that it is smaller and easier to
handle. The tool was optimized

23
00:01:16.710 --> 00:01:20.180
so that astronauts could remove
over 100 small screws during an

24
00:01:20.180 --> 00:01:24.351
instrument repair. The bits are
color coded so that the

25
00:01:24.351 --> 00:01:28.622
astronauts can find the right
bit faster. Their bit caddy, a

26
00:01:28.622 --> 00:01:31.725
device built to carry the bits
and hold them in place, can hold

27
00:01:31.725 --> 00:01:37.197
7 bits at a time. Moving along.
the standalone display case to

28
00:01:37.197 --> 00:01:41.668
the right discusses technologies
developed for this remarkable

29
00:01:41.668 --> 00:01:43.670
observatory that have made their
way into everyday products here

30
00:01:43.670 --> 00:01:46.340
on earth. These include digital
mammography systems that use a

31
00:01:46.340 --> 00:01:49.509
Hubble camera detector that is
used in the fight against breast

32
00:01:49.509 --> 00:01:52.546
cancer and a sky map computer
program used by amateur

33
00:01:52.546 --> 00:01:56.717
astronomers that is based on
Hubble’s star catalog. On the

34
00:01:56.717 --> 00:01:59.486
walls to the left of the
standalone display cases hang

35
00:01:59.486 --> 00:02:03.090
various awards received by the
operations team as well as a

36
00:02:03.090 --> 00:02:06.293
letter from the President of the
United States congratulating the

37
00:02:06.293 --> 00:00:00.000
team on 25 years of Hubble
operations.
