The Planetary Society solar sail team is working to try again to fly the world’s first solar sail spacecraft.

Almost since it was founded in 1980, The Planetary Society has been there for the search for other worlds.

Cosmos 1 was—and is—a great effort, and one we are proud The Planetary Society tried to do. Our independent grassroots organization built and launched a spacecraft whose technology promises to one day open up interstellar travel.

Following last year's Potentially Hazardous Asteroid and a few other non-main-belt discoveries, I looked into what improvements I could make to more efficiently image the sky. The major advance involved the design of a 3-lens corrector comprising 2 stock lenses and a custom lens I made myself.

In 2005, The Planetary Society awarded $32,500 as part of its Gene Shoemaker Near Earth Object (NEO) Grant Program. The grants were made to a group of international researchers to find, track, and characterize potentially hazardous NEOs.

The Volna Failure Review Board convened by the Makeev Rocket Design Bureau, manufacturers of the Volna launch vehicle, has made its final report to the Russian space agency, Roskosmos, concerning the attempted June 21 launch of our Cosmos 1 spacecraft.

Candidate signals sent in by users around the world will be quickly analyzed and compared to existing signals.

The Planetary Society continues to investigate the mystery of what happened to its Cosmos 1 spacecraft - a joint project with Cosmos Studios - that launched last week on a Russian Volna rocket.

The word failure is sticking in my craw. Certainly, we failed to achieve the objective of Cosmos 1: we did not achieve solar-sail flight. But I don’t think, with all we have done, that I can call Cosmos 1 a failure.

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.

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.

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.

When Cosmos 1, the first solar sail spacecraft, launches on June 21, 2005, it will carry into Earth orbit a CD containing the names of over 75,000 members of The Planetary Society and the Japan Planetary Society, along with the works of early visionaries who inspired solar sailing.

Rehearsals don't always go so well, which is the whole point of rehearsals. That was true both for us and for the Russians today, in separate simulations of mission operations.

Yesterday, we sent out an invitation to print, TV, and Web media for the launch event we'll be holding at our Pasadena headquarters on Tuesday. So today, the buzz really began about our mission, and the phones are beginning to ring off the hook.

The world’s first solar sail spacecraft, Cosmos 1, is now mated to its Volna launch vehicle and ready for its ride into space.

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.

Louis D. Friedman

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.

Astronomers have revised the Torino scale, the color-coded advisory system to assess the threat of asteroids and other near-Earth objects (NEOs) to make it easier for the public to understand.

As SETI@home has demonstrated, untold millions around the world are ready and eager to donate their computer time for the advancement of knowledge and the benefit of humankind. The story of distributed computing is only just beginning.
