The sub-orbital flight is expected to last about 32 minutes. It will be launched from a submarine  in the Barents Sea, and end with a touchdown on the Kamchatka peninsula. The test flight will demonstrate that the solar sail can unfurl in space. The test consists of the deployment of only two blades of Mylar polyester film. An inflatable re-entry shield will be used to return film from cameras aboard the sail after the half-hour flight ends with a landing on the Kamchatka peninsula.
