CubeSail was a 2018 low-cost spacecraft propulsion demonstration mission using two identical 1.5U CubeSat satellites to deploy a 260 m (850 ft) long, 20 m2 (220 sq ft) solar sail ribbon between them. This mission was a first in a series of increasingly-complex planned demonstrations leading up to a full-scale UltraSail heliogyro by the University of Illinois and CU Aerospace.
