Cosmos 1 Solar Sail Will Carry CD into Orbit
FOR IMMEDIATE RELEASE
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.
Cosmos 1 is a project of The Planetary Society and Cosmos Studios. Built in Russia, it will launch atop a converted ICBM from a submerged Russian submarine in the Barents Sea. Data obtained during the flight of Cosmos 1 will assist the world space community in analyzing and developing future solar sail technologies, such as those presaged on the CD in an historic essay by F.A. Tsander and a science fiction story by Arthur C. Clarke. See the full CD contents at http://www.planetary.org/solarsailcd/.
Cosmos 1 will be the first mission to test the concept of sailing on light, using the pressure of photons to propel it through space. Reflected light pressure will push against eight giant reflective blades, designed to adjust to the continuously changing orbital energy and spacecraft velocity.
Ann Druyan, CEO of Cosmos Studios and Cosmos 1 Project Manager, and Louis Friedman, Executive Director of The Planetary Society and Cosmos 1 Project Director, both have messages on the CD.
Druyan’s message says in part, “Our ancestors devised a means to ride the winds across the high seas…The names of these ancient explorers are lost to us. Today we honor their courage and genius with this first flight of Cosmos 1.”
The spacecraft was built by the Lavochkin Association and the Space Research Institute of the Russian Academy of Sciences in Russia. These space organizations are also investing in mission infrastructure to advance their own space-sailing ambitions. The Russians have built a new, lightweight spacecraft and utilized a low-cost launch system in a bid to develop a new series of scientific spacecraft.
Solar Sail Watch, a program designed for the general public, will invite people around the world to lend their help in tracking Cosmos 1 and photographing its progress across the night sky. Once its sails unfurl, Cosmos 1 will be bright enough to be easily visible to the naked eye. The Planetary Society and Cosmos Studios urge everyone to witness this historic mission first hand.
About The Planetary Society
The Planetary Society has inspired millions of people to explore other worlds and seek other life. With the mission to empower the world's citizens to advance space science and exploration, its international membership makes the non-governmental Planetary Society the largest space interest group in the world. Carl Sagan, Bruce Murray and Louis Friedman founded The Planetary Society in 1980. Bill Nye, a longtime member of The Planetary Society's Board, serves as CEO.
