The first-ever solar sail is scheduled for launch sometime after September aboard a Russian submarine-launched Volna rocket.

Once in orbit, Cosmos 1 will deploy eight solar sail blades that are supposed to use light energy from the Sun for propulsion. Ground controllers will analyze orbital data to see if the orbit is raised by even a small amount by the Sun’s rays.

The 88-pound spacecraft will also carry a camera that will capture pictures of the solar sails during the mission.
