Innovators at NASA’s Glenn Research Center have developed lightweight and reliable mechanisms based on shape memory alloys (SMAs) for small satellites such as CubeSats. SMAs have a unique ability to effect a reversible phase transformation, so that they can withstand being severely deformed and recovered repeatedly. Glenn’s innovation, flown in a successful space mission, uses SMA components in actuators and hinging elements to improve retention, release, and deployment of crucial structures such as solar arrays.
