clustermonkey writes "The first controllable solar sail was launched earlier today from a Russian sub in the Barents Sea. The Planetary Society, founded by Carl Sagan, organized the project and were funded by Cosmos Studios, founded by Sagan's widow. There have been 2 other solar sail deployments by others, but this will be the first to attempt controlled flight. The sail is scheduled to deploy June 25." All may not be well, though: Snot Locker writes "The Cosmos 1 Weblog is showing that, although the launch initially looked successful, they can't seem to find it or hear it. Bummer. Previous Slashdot coverage on the Cosmos 1 Solar Sail mission can be found here."
