Cosmos 1 was a project by Cosmos Studios and The Planetary Society to test a solar sail in space. As part of the project, an unmanned solar-sail spacecraft named Cosmos 1 was launched into space at 15:46:09 EDT (19:46:09 UTC) on June 21, 2005 from the submarine Borisoglebsk in the Barents Sea. However, a rocket failure prevented the spacecraft from reaching its intended orbit.
