"Spirit is the first of two golf-cart-sized rovers
headed for Mars landings in January. The rovers will seek
evidence about whether the environment in two regions
might once have been capable of supporting life. Engineers
at NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif.,
have navigated Spirit to arrive during the evening of
Jan. 3, 2004, in the Eastern time zone.
Spirit will land near the center of Gusev Crater, which
may have once held a lake. Three weeks later, Opportunity
will reach the Meridiani Planum, a region containing exposed
deposits of a mineral that usually forms under watery
conditions."
