View from Mars

It has been a while since we have seen a photo from Mars. Last week, scientists received new images from the Red Planet. The pictures were sent by Opportunity, a wheeled vehicle called a rover. Opportunity's mission is to explore Mars.

Last Wednesday, Opportunity reached the rim of Victoria Crater. It took the six-wheeled rover 21 months to get there. The crater is a half-mile wide and about 230 feet deep. The rover sent black-and-white pictures back to Earth. The pictures show tall rock walls and a sandy floor.

Scientists hope that Opportunity will keep exploring Mars for at least another year. It has already rolled along much longer than expected. It might enter the big crater to explore the inside. "Those layers of rock will tell us new stories about environmental conditions long ago," says NASA scientist Steve Squyres.
