Astronomy Picture of the Day

Explanation: NASA will launch two robots to Mars next year and you can help name them. The Mars Exploration Rovers are scheduled for launch on or near this coming June, when Mars and Earth are relatively close in their orbits. The landing craft are expected to touch down on Mars in January 2004 and deploy the robot rovers shortly thereafter. Rovers have the capability to crawl about 100 meters each day of their planned 90-day mission. The mission's scientific purpose is to seek out and inspect interesting rocks and terrain that could give clues to the past of Mars. Suggestions for names should be sent here, accompanied by a short essay, by 2003 January 31.
