Solar sail - Wikipedia
WEBSolar sails (also known as lightsails, light sails, and photon sails) are a method of spacecraft propulsion using radiation pressure exerted by sunlight on large surfaces. A number of spaceflight missions to test solar propulsion and navigation have been proposed since the 1980s.

What is solar sailing? - The Planetary Society
WEBSolar sailing is a revolutionary way of propelling a spacecraft through space. A solar sail spacecraft has large reflective sails that capture the momentum of light from the Sun and use that momentum to push the spacecraft forward. The Planetary Society’s LightSail 2 mission is one example of this technology in action.
