Imagine the Universe!

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.

Artist concept of spacecraft, starting with spin-down, momentum axis change, solar paddle deployment, and X-ray telescope extension.
