Opportunity Mars rover

The Opportunity Mars rover is doing a mission in a crater of Mars called Victoria Crater located at Meridiani Planum. The reason for this mission is to extract rocks and soil which when studied will give scientists the opportunity to get to know Mars from a million years ago. The problem is the crater is steep so the rover mission has to be done carefully and slow, but in the end it will be worth it.
