Lou Friedman is "our man in Japan" to watch IKAROS sail deployment

Emily Lakdawalla • June 03, 2010

Planetary Society Executive Director Lou Friedman is now in Japan, joining the rest of the IKAROS team to watch the eagerly anticipated deployment of its solar sails.

Firming Up the Spacecraft Design

Louis D. Friedman • May 27, 2010

The LightSail 1 spacecraft development is proceeding well. Our engineering team has completed crucial milestones to building the vehicle that will demonstrate the value and potential of using sunlight alone to propel exploratory craft through space.

Solar Sail Update: New Opportunities

Bruce Betts • April 01, 2009

At the beginning of this decade, we designed a mission to accomplish this goal. We launched Cosmos 1 in June 2005, but the Volna rocket that was to place the spacecraft in orbit failed, and we were never able to test our solar sail in flight. These days, The Planetary Society is working with colleagues at NASA and at the Russian Space Research Institute to put together a new solar sail mission.

New Developments on the Road to Cosmos 2

Louis D. Friedman • June 23, 2008

The Planetary Society and Cosmos Studios remain committed to flying the first flight with light. Our spacecraft, Cosmos 2, is a maneuverable solar sail that may be the precursor to a new mode of interplanetary travel, and could one day take us to the stars.

Cosmos 2

A letter from the Executive Director to the members and supporters of The Planetary Society.

Making Light Work

Louis D. Friedman • June 15, 2007

Professional Pilot Magazine asked me to contribute a prediction about the future of flight for the next century. Naturally, I wrote about solar sailing.

Update: Monitoring the Weather?

Louis D. Friedman • October 20, 2006

The bigger the dream, the harder it is to achieve it. Our dream at The Planetary Society is to fly the first solar sail mission -- and prove the technology that might someday take humanity to the stars.

Update: Getting Started

Louis D. Friedman • December 02, 2005

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

The End of Cosmos 1, the Beginning of the Next Chapter

Louis D. Friedman • September 30, 2005

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.

Volna Failure Review Board Reports on Loss of Cosmos 1

Louis D. Friedman • July 20, 2005

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.

The Planetary Society Asks "Where is Cosmos 1?" Received Signals May Have Come from Solar Sail Spacecraft in Orbit

Susan Lendroth • July 01, 2005

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 Story of Cosmos 1 is Not Over: A Personal Report

Louis D. Friedman • June 25, 2005

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.

Piecing the Data Together

Louis D. Friedman • June 23, 2005

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.

"We have a live spacecraft..."

Emily Lakdawalla • June 21, 2005

...we think.

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.

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.

Cosmos 1 Solar Sail will Carry CD into Orbit

Susan Lendroth • June 16, 2005

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.

The buzz begins!

Emily Lakdawalla • June 15, 2005

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.

Cosmos 1: Another rehearsal...

Emily Lakdawalla • June 15, 2005

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.

Cosmos 1 "Mated" to Volna Rocket in Preparation for Tuesday Launch

Louis D. Friedman • June 15, 2005

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