Ask an Explainer
Q:
Is redundancy used with thrusters and reaction wheels in satellites and space shuttles to increase its reliability?
A:
Backups are brought along in satellites and space telescopes to replace the thrusters or reactions wheels in case of malfunction. This makes the craft much more reliable, as it can stay in space longer without human intervention for repairs, which are very costly.
