It's definite now: Solar sail spacecraft lost
June 22, 2005A solar sail spacecraft failed to reach orbit because of an apparent booster rocket problem, Roskosmos, the Russian space agency said Wednesday.
The unmanned spacecraft, called Cosmos 1, was launched at 3:46 p.m. EDT Tuesday aboard a Volna rocket, Roskosmos said, from a Russian submarine in the Barents Sea. But 83 seconds after the launch, the craft experienced a spontaneous shutdown of the first stage rocket engine.
The spacecraft with eight triangular sail blades, each 16.5 yards long, was built under a contract with the U.S. Planetary Society. Scientists planned to study the possibility of using a solar sail as a traction system and as a way to control the spacecraft during its orbit flight.
An attempt in 2001 to test a spacecraft with two sail blades also failed, because the craft failed to deploy from its booster rocket.
