Pasadena, CA --"The next flight in the Cosmos 1 solar sail project will be an orbital test of an eight-bladed sail," announced Cosmos 1 Project Director Louis Friedman at a press conference in Pasadena, California on Wednesday, August 22. Friedman is also the Executive Director of The Planetary Society.

The Cosmos 1 team will not fly another sub-orbital test of the two-bladed spacecraft lost on July 20, 2001. Instead, they will move forward to launch to Earth orbit a spacecraft that will test deployment of the sail blades and initial operation of a full solar sail.

About the two-bladed test, Babakin Space Center General Director Konstantin Pichkhadze noted that "The experience gained preparing and integrating the payload was valuable enough to allow us to proceed to the next step."

The next test flight is expected to launch in early 2002. Like the previous deployment test, the spacecraft will launch on a Volna rocket, a converted inter-continental ballistic missile, from a Russian submarine in the Barents Sea.

July's sub-orbital test launched as planned, with the rocket flying on its correct trajectory. However, the spacecraft never separated from the third stage of the rocket and, thus, was unable to perform its mission to deploy two solar sail blades.

A Russian review team has determined the cause of the failed separation to be linked to insufficient thrust from the motor of the third stage. On board computers sensed less than normal thrust and commanded the spacecraft payload not to separate from the third stage. The failure was unusual – the Volna rocket had a record of 146 consecutive successes before this flight.

"This error had nothing to do with the payload or solar sail spacecraft, but was a rare problem in our rocket," said Viacheslav Danyelkin, Deputy Director of Makeev Rocket Design Bureau, which is responsible for the launch vehicle.

The Planetary Society and Cosmos Studios have directed Babakin to build a second spacecraft as backup for the test flight; this spacecraft would be available to conduct the actual solar sail mission. The goal of Cosmos 1 is to measurably increase its orbital energy in controlled flight, that is, to slowly expand the orbit further out from Earth.

"This is my first ‘third stage separation failure,'" said Ann Druyan, CEO of Cosmos Studios, "and, despite the outcome, it was a thrill! The vision of that missile breaking the surface of the sea -- not to destroy everything we love, but to take us inches closer to the stars -- was a peak experience. We are more committed than ever to the mission, and we can't wait to share it with the world on the A&E Network."

Solar sailing utilizes reflected light pressure pushing on giant panels, which adjust to the continuously changing orbital energy and spacecraft velocity. The sunlight pressure is powerful enough to push spacecraft between the planets from Mercury out to Jupiter. Beyond Jupiter, and out to the stars, space sailing can be done using powerful lasers focused over long distances in space.

Cosmos Studios is funding Cosmos 1 with additional support from the A&E Network. The project involves the cooperation of Russian space and defense organizations through a contract with The Planetary Society.

Russia's Babakin Space Center is the prime contractor for the project. The company is a spin-off organization of NPO Lavochkin, one of the largest manufacturers of robotic spacecraft in the world. Babakin is responsible for building the spacecraft and for mission operations. The Space Research Institute (IKI) of the Russian Academy of Sciences and Makeev Rocket Design Bureau also play major roles in project development. IKI is responsible for the spacecraft electronics, computer and one of the cameras. Makeev is responsible for development of the Volna rocket, which launched the suborbital test spacecraft in July and will launch the orbital test scheduled for 2002. Makeev coordinates with the Russian Navy for the launches.

Cosmos Studios and MPH Entertainment are producing a documentary on Cosmos 1 that will air on A&E Network in 2002.

About The Planetary Society:

The Planetary Society is headquartered in Pasadena, California, U.S.A. The organization was co- founded by Carl Sagan, Bruce Murray and Louis Friedman in 1980 to advance the exploration of the solar system, and to continue the search for extraterrestrial life. With 100,000 members in over 140 countries, the Society is the largest space interest group in the world. In addition to the Cosmos 1 solar sail, The Planetary Society conducts and supports numerous projects and activities, including the popular SETI@home distributed computing project and other searches for extraterrestrial intelligence, Red Rover Goes to Mars, and grants for astronomers searching for Near Earth Objects. The latest solar sail information will be posted on The Planetary Society's website at http://planetary.org.

About Cosmos Studios:

Founded by CEO Ann Druyan and company President Kent Gibson, Cosmos Studios seeks to build on the legacy of Dr. Carl Sagan by supporting cutting-edge scientific research, clean high technology and bold exploration - and engaging the widest possible audience in the romance of the adventure. Some of the ways Cosmos Studios is doing this are through its updating and presentation of the landmark COSMOS television series and its broadcast and re-issue on home video and DVD; its proud sponsorship of the SETI@home project, whose three million participants are actively engaged in the analysis of radio telescope data gathered in the scientific search for extraterrestrial civilizations; its support of scientific expeditions, including one that recently resulted in the discovery of a new genus of dinosaur; its creative alliances with the A&E Television Network , MPH Entertainment and Random House to create science-based entertainment events, books and accompanying curricula for students of all ages.
