Opportunity
Opportunity was a NASA Mars rover, part of the Mars Exploration Rover mission, that landed in Meridiani Planum on January 25, 2004. Originally designed for a 90‑sol mission, it operated for nearly 15 years—more than 5,000 sols—traversing over 45 km and providing strong evidence that Mars once held liquid water. It ceased communications after a global dust storm in June 2018 and was declared complete in February 2019.

A Path Into Victoria Crater
04/09/2007
What's inside Victoria Crater? Now that the dust has settled from the regional Martian dust storms that immobilized the rolling Martian rovers, the task ahead has become clear. Opportunity arrived at Victoria Crater last month and was poised to enter when the dust storms flared up unexpectedly. The above image was taken last week by the Opportunity rover perched at a possibly traversable slope into the 750-meter impact feature. Victoria Crater is the largest crater that either Martian rover has come across during their explorations. The crater walls might hold clues about the Martian surface before the tremendous impact that created Victoria Crater.
