LightSail 2 is a solar-powered spacecraft featuring several on-board batteries and a silver solar sail. The vessel was launched with the intention of demonstrating that solar power is a viable option for powering CubeSats, something the team has successfully accomplished, the Planetary Society announced on Tuesday.
