Imagine the Universe!

AUDIO:
The rotational speed of the spacecraft is gradually reduced over several days after lift-off and the rotational axis was changed to achieve the most stable configuration of the spacecraft five days after lift-off. Deployment of solar cell paddles adds sun acquisition control. The X-ray telescope was extended ten days after lift-off on March 2nd, and performance verification of observational instruments started.

VIDEO:
