Sunjammer (Solar Sail Demonstrator) was a NASA mission intended to demonstrate a solar sail constructed by LGarde, but was canceled before launch. The largest solar sail made as of 2013, Sunjammer was named after a 1964 Arthur C. Clarke story of the same name, Sunjammer, in which several solar sails compete in a race to the Moon. Sunjammer was slated to launch in January 2015 as the secondary payload of a SpaceX Falcon 9 launch vehicle, along with the Earth observation satellite DSCOVR. Citing a lack of confidence in its contractor's ability to deliver, the mission was canceled in October 2014.
