Spaceships pushed by LIGHT – the future of space travel?

This episode is brought to you by Squarespace: http://www.squarespace.com/physicsgirl

What if you could power a ship using sunlight instead of wind? Well in space, you can! Solar sails or light sails are pushed with light from the sun. Photons provide a kick when they reflect off the sail pushing the sail like an air molecule in the wind pushes a sailboat. Find out how a solar sail works and about the future of this technology!
