00:00:00.000 --> 00:00:08.880
When was the last space shuttle servicing mission to Hubble?

2
00:00:08.880 --> 00:00:13.040
Hubble is better than ever as a result
of the the servicing missions, 19 years

3
00:00:13.040 --> 00:00:17.640
of servicing missions, with the last
being SM4 in 2009.

4
00:00:17.640 --> 00:00:21.439
"And liftoff
of Space Shuttle Atlantis, the final

5
00:00:21.439 --> 00:00:25.519
visit to enhance the vision of Hubble
into the deepest grandeur of our

6
00:00:25.520 --> 00:00:28.780
universe!"

7
00:00:28.780 --> 00:00:32.640
We were able to replace any of the
hardware that we had been having

8
00:00:32.640 --> 00:00:35.760
problems with and we were also able to
upgrade our instruments

9
00:00:35.760 --> 00:00:39.360
so that for instance the wide field
camera that we have on board now is Wide

10
00:00:39.360 --> 00:00:43.420
Field Camera Three, it's the third
version of that.

11
00:00:43.420 --> 00:00:47.360
Each servicing mission we've been able
to upgrade the technology and we've got

12
00:00:47.360 --> 00:00:52.160
full redundancy of all of our critical
subsystems on Hubble still. Everything

13
00:00:52.160 --> 00:00:55.280
looks excellent
and we have no reason not to expect that

14
00:00:55.280 --> 00:01:01.160
Hubble will last until the late 2020s
and beyond.
