The Sunjammer mission – the name is borrowed from an Arthur C. Clarke short story about an interplanetary yacht race — will unfurl a solar sail that dwarfs those that have thus far been tested in space. Where NanoSail-D’s diminutive sail measured just 100 square feet and Japan’s IKAROS measures something like 2,000 square feet, Sunjammer’s sail possesses a total surface area of nearly 13,000 square feet. Yet collapsed it weighs just 70 pounds and takes up about as much space as a dishwasher, making it easy to stow in the secondary payload bay of a rocket headed to low Earth orbit.“
Popular Science previews the flight of NASA’s Sunjammer, set for launch in 2014. “The destination for Sunjammer is the Earth-Sun Lagrange Point 1, a gravitationally stable spot way out there between us and our nearest star…Sunjammer will be carrying the cremated remains of various individuals, including Star Trek creator Gene Roddenberry and his wife Majel Barrett Roddenberry.”
