The CapSat-1 is a technological demonstration, selected on March 14th, 2019 through NASA’s tenth annual CSLI round . It is designed to validate a capacitor-based electrical power system (EPS) in a 1U CubeSat. Currently, all CubeSats use lithium-ion polymer (LiPo) batteries as their primary source of power. Capacitors have been proven to be safer, more cost/volume-efficient, and more temperature-durable than LiPo batteries. This mission would validate their power/voltage efficiency and compare that to the status quo of the EPS in CubeSats today.
This CubeSat will launch as a 1U, and its launch date is expected within mid-to-late 2021. The CapSat1 was classified by NASA with a secondary mission of technological demonstration, and a primary mission of education – by giving younger engineers the opportunity for hands-on experiential learning with how to develop, build, test, and fly a satellite.
