This overview map made from Mars Orbiter camera images illustrates the path that the Mars Exploration Rover Spirit has taken from its first sol on the red planet through its 107th sol. As of sol 112 (April 26, 2004), Spirit has passed "Missoula" crater and sits approximately 1,900 meters (1.18 miles) away from its destination at the western base of the "Columbia Hills." While most of Spirit's journey has been over the very angular rocks that make up the ejecta fields surrounding "Bonneville" crater, the rover's next 50 or so sols will be spent traversing over martian plains that are dominated by rounder, vesicle-filled rocks.

This overview map made from Mars Orbiter camera images illustrates the path that the Mars Exploration Rover Opportunity has taken from its first sol on the red planet through its 87th sol. After thoroughly examining its "Eagle Crater" landing-site, the rover moved onto the plains of Meridiani Planum, stopping to examine a curious trough and a target within it called "Anatolia." Following that, Opportunity approached and remotely studied the rocky dish called "Fram Crater." As of its 91st sol (April 26, 2004), the rover sits 160 meters (about 525 feet) from the rim of "Endurance Crater."

Opportunity could be at the crater rim in a matter of days!!!
