View Full Version : Launch Date Set for Solar Sail

2005-Sep-11, 03:07 AM
SUMMARY: The countdown has begun for the launch of the Planetary Society's Cosmos 1 spacecraft; the first ever to be powered by a solar sail. The privately built spacecraft will be lofted into orbit atop a Volna rocket on March 1, 2005. Once Cosmos 1 is in orbit, it will unfurl 8 triangular solar sails, and then use the sails to propel the spacecraft through the pressure of light from the Sun. Cosmos 1 wasn't designed for a long-term trip into space, so it's likely not to last too much longer than a few weeks, or months at the most, but it should serve as a working concept to help designers plan future spacecraft.
