The solar sail aboard NASA‘s Advanced Composite Solar Sail System (ACS3) satellite has successfully deployed, using a spacecraft bus from Kongsberg NanoAvionics (NanoAvionics). Telemtry and images from the satellite's onboard camera confirmed the deployment, a primary objective of the ACS3 mission. The ACS3 mission, which NASA’s Ames Research Center led and operated, is a technology demonstration to test an 860-square-foot (80-square-meter) solar sail and new deployable composite boom technologies for future space missions.
