PASADENA, CALIFORNIA (BNS): The team operating NASA's Curiosity Mars rover on Mars 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", according to a news release by NASA.

The rover found evidence of an ancient environment favourable 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."

This second drilling is intended to confirm results from the first drilling, which indicated the chemistry of the first powdered sample from John Klein was much less oxidizing than that of a soil sample the rover scooped up before it began drilling, the release added.

Curiosity is about nine months into a two-year prime mission since landing inside Gale Crater on Mars. After the second rock drilling in Yellowknife Bay and a few other investigations nearby, the rover will drive toward the base of Mount Sharp, a 3-mile (5-kilometer) tall layered mountain inside the crater.
