Aboard SpaceX’s latest Falcon launch today was a large reflective solar sail.  https://trib.al/CPE2DPe 

The aim is for the sail to reach 450 miles above Earth, and then orbit for about a year.  https://trib.al/CPE2DPe 

Engineers on the ground will be able to steer it by adjusting the angle of the sails, just like on a boat.

But instead of using the wind to move, the solar sail will use the energy of photons as they strike its gigantic mylar sails to move.  https://trib.al/CPE2DPe
