It is thought that thousands of years
ago, everything was fertile...
:14:07
...but a change in climate
turned North Africa into a desert.
:14:12
What will future climatic changes
do to our Earth and to us?
:14:17
We're still looking for a deploy
over that MlLA pass...
:14:21
Okay. How's that?
:14:23
In search of the answer, Sally Ride
deploys a satellite called ERBS.
:14:30
That's a pretty spacecraft.
:14:32
- Challenger, you're go for release.
- We'll put it in work.
:14:37
ERBS will help us know if there'll
be more sandstorms in our future...
:14:42
...or blizzards
or hurricanes like Josephine...
:14:46
...500 miles in diameter...
:14:48
...and packing winds
of 90 miles an hour.
:14:53
- We're seeing not even half of it.
- There's the eye of the storm.

The U.S. East Coast is to the right.
:15:06
Now the mid-deck has become
part gymnasium and part factory.
:15:11
While Steve Hawley exercises...
:15:13
...Charlie Walker operates a compact
laboratory on the far bulkhead.
:15:21
This is a commercial venture...
:15:23
...to develop new kinds
of medicines...
:15:26
...that can only be made
in zero gravity.
:15:33
Ten seconds. Nine, eight,
seven, six, five...
:15:38
- Got it armed?
- Got it armed. Three, two, one.
:15:42
The five-string arm is off.
:15:45
The nexus is inabled.
:15:52
- Congratulations, three for three.
- I'm gonna close the sun shield.
