NASA Announces Mars & Comet Mission Coverage NASA

On Jan. 3, NASA’s Mars Exploration Rover Project will deliver the first mobile laboratory to the surface of Mars. The rover will perform robotic geological fieldwork that may reveal a history of water on Mars. Engineers at NASA’s Jet Propulsion Laboratory (JPL), Pasadena, Calif., have navigated the first rover, Spirit, to arrive at Mars at approximately 11:35 p.m. EST Jan. 3. Three weeks later, the second rover, Opportunity, will reach the Meridiani Planum, a region containing exposed deposits of a mineral that usually forms under watery conditions.
