NASA Curiosity Rover Team Selects Second Drilling Target On Mars


The team operating NASA’s Curiosity Mars rover has selected a second target rock for drilling and sampling. The rover will set course to the drilling location in coming days.

This second drilling target, called “Cumberland,” lies about nine feet (2.75 meters) west of the rock where Curiosity’s drill first touched Martian stone in February. Curiosity took the first rock sample ever collected on Mars from that rock, called “John Klein.” The rover found evidence of an ancient environment favorable for microbial life. Both rocks are flat, with pale veins and a bumpy surface. They are embedded in a layer of rock on the floor of a shallow depression called “Yellowknife Bay.”

“We know there is some cross-contamination from the previous sample each time,” said Dawn Sumner, a long-term planner for Curiosity’s science team at the University of California at Davis. “For the Cumberland sample, we expect to have most of that cross-contamination come from a similar rock, rather than from very different soil.”
