1200 square meter solar sail preparing January 2015 launch

Sunjammer is a solar sail constructed by LGarde for NASA. The largest solar sail to be constructed as of 2013, Sunjammer was named after a 1964 Arthur C. Clarke story of the same name, in which several solar sails compete in a race across the Solar System. Sunjammer is slated to launch in January 2015 as the secondary payload of a SpaceX Falcon 9 rocket, along with the Earth observation satellite DSCOVR.
