00:00:02,469 --> 00:00:05,705
[Outer Barrel Assembly (OBA) Struts
Loaded with aluminum weights to simulate other parts of the spacecraft, 

3
00:00:05,705 --> 00:00:08,241
the black OBA struts are mounted on the centrifuge]

4
00:00:09,509 --> 00:00:13,380
[Spinning at 3 G
simulates launch and thrust loads.]

5
00:00:18,084 --> 00:00:22,355
[Unloading
Removing the weights to prepare the struts for moving.]

6
00:00:25,859 --> 00:00:31,998
[OBA on the Move

[OBA Shell Section
In a cleanroom, protective wrap and mass sims

8
00:00:37,203 --> 00:00:40,607

9
00:00:48,148 --> 00:00:53,053
[Connecting the pieces
Shell lifted and moved to connect with the support strut section.]

10
00:01:04,230 --> 00:01:07,734
[Switching places
The shell is lifted from struts which are pushed back out.

11
00:01:07,734 --> 00:01:11,004
Then the shell is attached to the centrifuge.]

12
00:01:13,873 --> 00:01:17,143
[Spinning at 3.9 G
The shell is spun in the first of several positions.]
