First solar sail spacecraft lost.

The world’s first solar sail spacecraft crashed back to Earth when its booster rocket failed less than two minutes after Tuesday’s takeoff, Russian space officials said Wednesday.

The Cosmos 1 vehicle, a joint U.S.-Russian project, was intended to show that a solar sail can make a controlled flight. Solar sails, designed to be propelled by pressure from sunlight, are seen as a potential means for achieving interstellar flight, allowing such spacecraft to gradually build up great velocity and cover large distances.

But the Volna booster rocket failed 83 seconds after its launch from a Russian nuclear submarine in the northern Barents Sea just before midnight Tuesday in Moscow, the Russian space agency said.
Its spokesman, Vyacheslav Davidenko, said that “the booster’s failure means that the solar sail vehicle was lost.” The Russian navy began a search for debris from the booster and the vehicle, he said.
