LightSail2

• The LightSail 2 is a project to demonstrate controlled solar sailing using a miniature CubeSat satellite.

• It will be launched from the Kennedy Space Center, Florida, US in April 2019.

• LightSail 2 is the second of three satellites built to demonstrate the feasibility of powering a spacecraft using solar radiation.

• This mission is designed to see if LightSail can move into higher orbits around the Earth using only photons from the sun to push it along.

Solar Sailing

• Solar sails (also called light sails or photon sails) are a proposed method of spacecraft propulsion using radiation pressure exerted by sunlight on large mirrors.
