Mars rover approaches long-term goal

Endeavour crater offers the setting for plenty of productive work by Opportunity.
The NASA Mars rover Opportunity has gained a view of Endeavour crater from barely more than a football-field's distance away from the rim. The rim of Endeavour has been the mission's long-term goal since mid-2008.

Endeavour offers the setting for plenty of productive work by Opportunity. The crater is 14 miles (22 kilometers) in diameter — more than 25 times wider than Victoria crater, an earlier stop that Opportunity examined for 2 years. Observations by orbiting spacecraft indicate that the ridges along Endeavour's western rim expose rock outcrops older than any Opportunity has seen so far. The selected location for arrival at the rim, "Spirit Point," is at the southern tip of one of those ridges, "Cape York," on the western side of Endeavour.

Opportunity and Spirit completed their 3-month prime missions on Mars in April 2004. Both rovers continued for years of bonus, extended missions. Both have made important discoveries about wet environments on ancient Mars that may have been favorable for supporting microbial life. The mission of the Spirit rover, for which Spirit Point was named, was concluded in May, 2011, after the rover did not re-establish communications following the martian winter.
