The 2004 Mars Exploration Rover Mission: Evidence for Water and Prospects for Life
The Mars Exploration Rover Mission, part of NASA's Mars Exploration Program, reveals evidence for water and prospects for life on Mars. The Mars Exploration Rovers landed on Mars in January 2004. These twin Robots, Opportunity and Spirit, were sent to opposite sides of the planet. Spirit was sent to Gusev carter where it went on to climb to the top of Husband Hill. Opportunity was sent to Meridiani Planum where it discovered sedimentary rocks formed by aqueous processes. The goals of the Mars Exploration Rover Mission were to characterize the climate and geology of Mars, determine if life ever arose on Mars, and prepare for human exploration of Mars. -- The rovers, equipped with scientific tools in order to collect and analyze data on Mars, have operated for over 1,200 days, analyzed dozens of rocks and soils, and returned over 100,000 images. This data enables scientists to better understand past and present conditions on Mars. Dr. John Grotzinger, who is part of the Athena Science Team (which consists of over 150 scientists and several hundred engineers), will share the latest discoveries about the mysterious red planet known as Mars.
