Hubble changing orientation

This animation, taken from Hubblecast 78: Dr J Q&A part 1, shows Hubble’s orientation changing.

Hubble cannot be moved to a different orbit as it has no engine. But, we can change its orientation. This is useful for taking observations and for avoiding space debris. If debris can’t be avoided, then the sturdier, less delicate, back of Hubble can be turned towards the impact.
