745211 story NASA to Launch Solar Sail 147 Posted by timothy on Saturday June 28, 2008 @12:31PM from the cue-bad-brains dept. arbitraryaardvark writes "Physorg reports that NASA will launch a solar sail around the end of July. It'll be the first of its kind; a previous attempt blew up. It's a small proof-of-concept gizmo, not a full-on spaceyacht. Solar sails operate on photon pressure from sunlight. They are well known to science fiction readers, otherwise not so much." C-net has coverage, too.
