NASA will launch huge solar sail in 2014

SunjammerNASA announces plans to launch an experimental uncrewed test vehicle called Sunjammer into orbit in 2014, as a test of solar sail technology. Though not the first solar sail ever launched, Sunjammer be will the largest by far, its mainsail being incredibly thin Kapton with a surface area of 13,000 feet. The objective of the flight is to unfurl the sail and then use the solar wind to propel it to the L1 Earth-Sun LaGrange point nearly 2,000,000 miles from Earth. Sunjammer will be lifted into orbit by a SpaceX rocket in 2014, with both NASA and NOAA keeping a close eye on the results.
