5 days ago · The primary objective of the ACS3 technology demonstration is the successful deployment of the composite boom solar sail in low-Earth orbit. After reaching space, the ACS3 spacecraft will deploy its solar power arrays and then begin unfurling its solar sail via four booms that span the diagonals of the square and unspool to reach 23 feet (about 7 meters) in length.
