What's It All About?

Science Channel will broadcast live coverage of mankind's next major step in Mars exploration with Mars Live: The Phoenix Lands premiering Sunday, May 25, 2008, at 7 p.m. ET, 4 p.m. PT. Originating LIVE from the Jet Propulsion Laboratory in Pasadena, Calif. and the University of Arizona's Lunar and Planetary Laboratory, the program will give viewers a first look at photos sent back from the Mars surface, and exclusive, in-depth analysis and perspective of the mission's historic scientific implications from NASA Chief Scientist Dr. James B. Garvin, as well as firsthand reactions from scientists including Phoenix Mars Mission Principal Investigator Peter Smith.

In what is designed to be mankind's best effort to date to find life on Mars, the rover has covered 422 million miles over the past nine months. Its mission is to help answer questions about life-supporting conditions on the planet by analyzing ice from the northern Martian arctic using a suite of onboard, state-of-the-art instruments.

Dr. James B. Garvin is the world's leading expert on the surface of Mars. Throughout the broadcast, Dr. Garvin will be your guide as the Phoenix Lander approaches the surface of Mars, will lend valuable perspective on what scientists are seeing and may find, and can speak to what conditions the Phoenix is facing on Mars.

Following the show, Science Channel looks back at recent missions to the red planet with encore presentations of Revealing Mars at 9 p.m. ET/6 p.m. PT and Roving Mars at 10 p.m. ET/7 p.m. PT. Revealing Mars walks viewers through NASA's Mars Reconnaissance Orbiter's (M.R.O.) scientific payload and the high-tech instruments used to capture stunning images of Mars. The M.R.O. was launched in 2005. Roving Mars immerses viewers in the journeys of Spirit and Opportunity, two rovers that explored the red planet on remote, unmanned NASA missions. Spirit and Opportunity launched in June 2003 and landed on Mars in January 2004.
