NASA to Launch World’s Largest Solar Sail in 2014
The largest solar sail ever constructed is headed for the launch pad in 2014 on a mission to demonstrate the value of “propellantless propulsion”— the act of using photons from the sun to push a craft through space.
Dubbed Sunjammer, the giant solar sail measures about 124 feet (38 meters) on a side and boasts a total surface area of nearly 13,000 square feet (1,208 square m, or one-third of an acre). The project is under the wing of NASA’s Space Technology Program, within the agency’s Office of the Chief Technologist.
NASA has contracted with a team of high-tech “solar sailors” at L’Garde Inc. of Tustin, Calif., to build Sunjammer.
