Mars rovers still roving

Those plucky Mars rovers are still going. Their planned roving time was three months but now more than four years in, NASA is sending Opportunity off on a two-year trek to visit a large crater.

The mission team estimates Opportunity may be able to travel about 100m per day. But even at that pace, the journey could take two years. The rover will stop to study rocks on the way, and in winter months it cannot move because there is not enough sunlight to provide sufficient power for driving.

Mars Reconnaissance Orbiter recently snapped a picture of the Opportunity rover perched on the rim of Victoria Crater. Opportunity drove more than 5 miles from its landing site to get there. High resolution photo here. Here’s where Opportunity is located on Mars.
