Cosmos 1 is a prototype solar sail whip which uses 14m long sails and the solar wind to propel itself through near solar space. It's due for launch in October. One of its neatest features though is that it is being launched on a SLBM from a Russian nuclear submarine - eat your heart out Sky-One. Cosmos-1 is part funded by The Planetary Society, co-founded by space visionary Carl Sagan.
