TIMELINE: The unexpectedly long life of the Mars rover ‘Oppy’
Opportunity, otherwise known as “Oppy,” was a rover created by NASA as a part of their Mars Exploration Rover (MER) program. The MER mission included two Mars rovers, both Opportunity and Spirit; Spirit was active from 2004 – 2010. In July 2003, the rover Oppy began its journey to Mars. It took Opportunity about 6 months to land on Mars, where it was expected to last roughly 90 days.
