Hubble Trivia: 5) What Does Hubble Use to Turn Itself and Point at a Target?

The video tutorial explains how spacecrafts use attitude control mechanisms, specifically reaction wheels, to adjust their orientation in space. Reaction wheels, which are about 2 feet wide, allow the telescope to rotate in the opposite direction when spun. This enables the telescope to move across the sky and focus on different targets. Typically, the telescope will lock onto a target for about two orbits, with each orbit lasting approximately 95 to 97 minutes.
