Rover Curiosity carries 10 instruments to help it determine whether its Gale Crater landing site has ever been capable of supporting microbial life. But CheMin and another instrument on the 1-ton rover's body, known as Sample Analysis at Mars (SAM), are the rover's core scientific gear.
SAM is a chemistry laboratory that can identify organic compounds — the carbon-containing building blocks of life as we know it. The instrument has been sniffing the Martian air already, but it has yet to analyze its first soil sample. That should change in a week or so, Grotzinger said, after further cleaning of the rover's sampling system.
Curiosity continues to be in good health, researchers said. After the six-wheeled robot finishes testing out its scooping and sampling systems at Rocknest, mission scientists will begin searching for a spot to break out the rover's rock-boring drill. The first drill activity will be a complicated affair that could take month or so all up, Grotzinger said.
Curiosity is currently checking out deposits near a site called "Glenelg," where three interesting types of Martian terrain come together. But its ultimate destination is the base of Mount Sharp, the 3.4-mile-high (5.5 kilometers) mountain rising from Gale Crater's center.
Mount Sharp's foothills show signs of long-ago exposure to liquid water. Curiosity could be ready to start rolling toward the mountain's interesting deposits — which lie about 6 miles (10 km) away — in a couple of months.
"I would hope we'd be on our way by the end of the year," Grotzinger said.
