“Liftoff of the Space Shuttle Discovery with the Hubble Space Telescope, our window on the universe!”

2
00:00:06,560 --> 00:00:18,000
In 1990, the Hubble Space Telescope was launched
into space to be our window to the universe.

3
00:00:18,000 --> 00:00:27,683
Since then, Hubble has provided the world 
with its stunning images of the cosmos.

4
00:00:27,683 --> 00:00:36,505
But on June 13, 2021, Hubble’s
payload computer unexpectedly came to a halt.

5
00:00:36,505 --> 00:00:46,976
The Hubble team attempted to bring
the computer back online but with no success.

6
00:00:46,976 --> 00:01:00,000
Team alumni and retirees joined the effort to methodically
identify the failure’s cause and possible solutions. 

7
00:01:00,000 --> 00:01:15,000
They updated and tested procedures to perform
a very complex hardware switch.

8
00:01:15,000 --> 00:01:21,797
On July 15, the team performed 
15 hours of spacecraft commanding...

9
00:01:21,797 --> 00:01:30,000
...and successfully completed the challenging
and risky switch to backup hardware.

10
00:01:30,000 --> 00:01:39,172
They then successfully brought the 
science instruments back online.

11
00:01:39,172 --> 00:01:45,001
Science observations are now flowing again...

12
00:01:45,001 --> 00:01:51,561
…as Hubble continues uncovering 
the mysteries of the universe.
