00:00:00.867 --> 00:00:03.870
NASA's Interstellar
Mapping and Acceleration Probe,

2
00:00:03.870 --> 00:00:07.640
or IMAP, is undergoing extreme
testing at NASA's

3
00:00:07.640 --> 00:00:10.643
Marshall Space
Flight Center in Huntsville, Alabama.

4
00:00:11.711 --> 00:00:14.147
After unloading, the spacecraft was lifted

5
00:00:14.147 --> 00:00:17.150
into one of Marshall's
thermal vacuum chambers.

6
00:00:17.984 --> 00:00:22.856
Inside the chamber, a 28-day test mimics
the extreme environment of space,

7
00:00:22.856 --> 00:00:27.560
including temperatures as cold as -148°F.

8
00:00:28.194 --> 00:00:31.398
In space, IMAP will study the heliosphere,

9
00:00:31.398 --> 00:00:34.868
the magnetic bubble surrounding
and protecting our solar system.

10
00:00:35.335 --> 00:00:38.805
Once testing is complete,
the spacecraft will be shipped to NASA's

11
00:00:38.805 --> 00:00:40.540
Kennedy Space Center in Florida,

12
00:00:40.540 --> 00:00:43.977
where it's slated to launch
no earlier than September 2025.
