NASA Rover Reaches Edge of Endeavour Crater on Mars After Three Year Journey

Posted on August 13, 2011

NASA's Mars Exploration Rover Opportunity has reached the edge of the Endeavour Crater on Mars. The crater will give NASA to study rocks that have never been examined before. It took Opportunity three years to get to the crater after traveling nearly 13 miles. The crater is 14 miles in diameter. The west rim of the crater is pictured above.

NASA project manager John Callas says, "We are interested in Endeavor crater because we see in its rim evidence of clay minerals. Clay minerals are a class of mineral that form in neutral Ph water. This is very exciting from the possibility of Mars at one time being a habitable planet."
