Private Solar Sail Orbiter Launches

From the exciting field of private sector space innovation:

A privately funded and experimental spacecraft blasted off on Tuesday from a Russian submarine in a venture funded by space enthusiasts who see their solar-driven orbiter as a way to reinvigorate a race to the stars. Cosmos 1, the world’s first solar sail spacecraft, launched in the tip of a converted Russian intercontinental ballistic missile from the Barents Sea for the start of a mission that cost just $4 million.
