In a science update on Curiosity’s research in Gale Crater, this Science journal article today gives a good overall update on Curiosity’s technical condition.

Since early December 2016, Curiosity hasn’t been able to drill. The problem, likely a stuck brake on the mechanism for extending the drill bit, is serious. “There is apprehension,” says Ashwin Vasavada, Curiosity’s project scientist at the Jet Propulsion Laboratory in Pasadena, California. But the drill still responds intermittently. “We’re not in a situation where it’s completely dead.”

Still, the clock is ticking for the aging rover, and some outside scientists regret not having used a wet chemistry cup. Rocks have punctured its wheels, and the output of its decaying radioactive power source has dropped by 15%. Jack Mustard, a planetary scientist at Brown University, says he understands the team’s hesitancy. But he wished the “mission had moved more quickly with the wet chemistry experiments,” he says. “I am eager to see what we can learn.”

The wet chemistry cup, designed to look for organic life, is an experiment that requires use of the drill but the science team has held off doing. Now it might be too late.

At the moment Curiosity is approaching [see Sol 1598-1599] the small hill that had been to its southwest in my January 18, 2017 update and shown in the image above. I had thought they might make a side trip there on their way up Mount Sharp, and they have, with their actual route taking them around the backside of the hill.

    Looking at that picture I wonder what is its geological history and what minerals might we find? Robots are very limited in what they can tell us.
