The clever engineering of JWST’s mirror actuators

The cryogenic mirror actuators on JWST are amazing feats of engineering. Capable of long travel and nanometer precision, able to survive rocket launch, cryogenic temperatures and hard vacuum... they are really impressive devices. And they use flexures!
