NASA’s Mars Rover to Head Toward Bigger Crater

NASA’s Mars Rover Opportunity is setting its sights on a crater more than 20 times larger than its home for the past two years.

To reach the crater the rover team calls Endeavour, Opportunity would need to drive approximately 12 kilometers (7 miles) to the southeast, matching the total distance it has traveled since landing on Mars in early 2004. The rover climbed out of Victoria Crater earlier this month.

“We may not get there, but it is scientifically the right direction to go anyway,” said Steve Squyres of Cornell University, principal investigator for the science instruments on Opportunity and its twin rover, Spirit. “This crater is staggeringly large compared to anything we’ve seen before.”

Getting there would yield a look inside a bowl 22 kilometers (13.7 miles) across. Scientists expect to see a much deeper stack of rock layers than those examined by Opportunity in Victoria Crater.

“I would love to see that view from the rim,” Squyres said. “But even if we never get there, as we move southward we expect to be getting to younger and younger layers of rock on the surface. Also, there are large craters to the south that we think are sources of cobbles that we want to examine out on the plain. Some of the cobbles are samples of layers deeper than Opportunity will ever see, and we expect to find more cobbles as we head toward the south.”
