After 11 years and 2 months, NASA’s Opportunity rover has completed a record 26.2-mile (42.2 kilometers) drive across Mars. Some highlights along the way:

1. EAGLE CRATER: 
After landing, Opportunity found signs of acidic water in Mars’ ancient past.
 
2. ENDURANCE CRATER: 
Rock layers indicated this area was wet only from time to time. Any microbes would have had a tough time surviving.
 
3. VICTORIA CRATER: 
Findings at this site made scientists wonder: “Was the water of ancient Mars too salty for life?”
 
4. ENDEAVOUR CRATER: 
Opportunity finally discovered signs of past water that would have been hospitable to life.
 
5. NEXT, MARATHON VALLEY: 
Opportunity will explore clay that suggests Mars might have made a good habitat for life in the past.
 
A marathon is a traditional running event dating back to the legends of the ancient Greeks.
