Cosmos 1


 
 

Cosmos 1 was a project by The Planetary Society to test a solar sail in space. As part of the project, an unmanned solar sail spacecraft 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 it from reaching its intended orbit. Once in orbit, the spacecraft was supposed to deploy a large sail, upon which photons from the Sun would push, thereby increasing the spacecraft's velocity (the contributions from the solar wind are similar, but of much smaller magnitude).

Had the mission been successful, it would have been the first-ever orbital use of a solar sail to speed up a spacecraft, as well as the first space mission by a space advocacy group. The project budget was USD $4 million.

Planetary Society: The Planetary Society is a large, publicly-supported, not-for-profit organization that has many research projects related to astronomy. It is based in Pasadena, California, but has an international membership. It was founded in 1980 by Carl Sagan, Bruce Murray, and Louis Friedman. The Society is d...

Solar sail: Solar sails (also called light sails, especially when they use light sources other than the Sun) are a proposed form of spacecraft propulsion utilizing large membrane mirrors. Radiation pressure is small and decreases by the square of the distance from the sun, but unlike rockets, solar sails requir...
