ACS3 (Advanced Composite Solar Sail System)is a technology demonstration designed to characterize solar sail structures technologies for future small spacecraft to engage in deep space missions requiring long-duration, low-thrust propulsion.
The deployable composite boom and solar sail technologies demonstrated will guide the development of a larger mission-capable CubeSat-class solar sail propulsion system to be demonstrated in the 2025 timeframe.
ACS3 is build to the 6U CubeSat standard. It will feature four 6.85 m long deployable composite booms to span a 85 m2 solar sail with 9.2 m edge length.
It was selected in 2019 by NASA to be launched as part of the ELaNa program.
