We’ve had a very exciting day here in Moscow. Bud Schurmeier and I met with Konstantin Pichkhadze, head of the Lavochkin Association, which built our spacecraft, Cosmos 1.

The Launch of Cosmos 1: Live Reports

Bruce Betts • June 21, 2005

In the past twenty-four hours, the Russian space agency (RKA) has made a tentative conclusion that the Volna rocket carrying Cosmos 1 failed during the firing of the first stage. This would mean that Cosmos 1 is lost.

Final Words Before Launch

Louis D. Friedman • June 21, 2005

Speaking by phone to a roomful of journalists in Pasadena less than 2 hours before the expected launch, project director Louis Friedman reiterated his confidence in the entire Cosmos 1 team.

Cosmos 1 Solar Sail will Carry CD into Orbit

Worldwide Network to Track Cosmos 1

Susan Lendroth • June 02, 2005

From Moscow to the Marshall Islands and California to the Czech Republic, tracking stations around the world will receive data from Cosmos 1, the world's first solar sail spacecraft after it launches on June 21, 2005.

Launching Cosmos 1 on a Soviet ICBM

Louis D. Friedman • May 25, 2005

The biggest reason that NASA—as well as other western space agencies—has not attempted a solar sail flight is that the cost of launching even a small spacecraft is so high that they are unwilling to carry out a mission with very modest goals.
