Summer Intern works on the Advanced eLectrical Bus (ALBus) CubeSat: From Build to Flight Advanced eLectrical Bus (ALBus) CubeSat: From Build to Flight A new CubeSat, launched Sunday, December 16, will test high power electric systems and the use of unique shape memory alloy (SMA) components for the first time. CubeSats are very small, lightweight satellites, about the size of a loaf of bread, and typically operate within a power range of 5-20 watts. Lower power systems are typically used in CubeSats because of size and weight limits, while higher power systems and components cause excessive heat. Completely designed and led by a team of 12 early career scientists and engineers at NASA’s Glenn Research Center in Cleveland, the Advanced Electrical Bus, or ALBus, will be the first CubeSat to demonstrate power management and distribution of a 100-watt electrical system. The CubeSat will also employ a custom-built SMA release mechanism and hinges to deploy solar arrays and conduct electricity.
