Curiosity’s first drilling sample has found that the ancient watery conditions in Gale Crater were especially suitable for life.
As a precaution engineers have temporarily shut Curiosity down to protect it from an oncoming solar flare.
They have done this in conjunction with the rover’s recent computer memory problem.
Curiosity is easing out of safe mode as engineers switch computers.
Corrupt memory in Curiosity’s A computer system has forced engineers to switch to the rover’s back-up computer.
The problem came to light Wednesday morning on Mars when flight controllers at the Jet Propulsion Laboratory in Pasadena, Calif., noticed what appeared to be memory corruption in the computer’s solid-state memory system. The flight software was not recording new data or playing back data already recorded. Instead, it was only sending back real-time telemetry. Later in the day, during a communications session using NASA’s Mars Reconnaissance Orbiter, telemetry from Curiosity indicated the corrupted memory was still present. In addition, Cook said, flight controllers saw the computer had not completed several pre-planned activities.
At that point, the computer was expected to put itself to sleep for an hour or so and then to wake up for a communications session with NASA’s Odyssey orbiter. “It was after that second overflight that we got some more information saying hey, the memory is still corrupted and oh by the way, I didn’t go to sleep when I was supposed to, I stayed awake,” Cook said.
The next communications session came late Wednesday night Earth time, between 10:30 p.m. and midnight at the Jet Propulsion Laboratory. The rover’s computer was still awake and engineers decided to switch over to the B-side system.
The engineers suspect the problem was caused by a cosmic ray hit, and can be fixed by rebooting the computer.
Boom! A newly discovered comet has an orbit that might have it collide with Mars in October 2014.
R.I.P. Dr. David S. McKay: 1936-2013. More here.
Though he was most famous for being the lead author of the 1996 paper suggesting that fossil life had found in a Martian meteorite, McKay was one of the giants of planetary science whose work was far more extensive and important. He will be missed.
Curiosity has obtained its first drill sample.

The first nighttime photos from Mars.
The seasons change on Mars.
With three years of data in hand the researchers report on the sequence and variety of changes that take place over the spring, including outbursts of gas carrying sand, polygonal cracking of the ice on the dunes, sandfalls down the slipface of the dunes, and dark fans of sand propelled out onto the ice. Gas escaping from under the seasonal layer of dry ice erodes channels in the dunes, reminiscent of the erosion that carves more permanent “spider” channels in the southern hemisphere polar region.
Happy 9th anniversary to the Opportunity rover on Mars!
Talk about getting your money’s worth: The rover was planned as a 90 day mission.
Data from Mars Reconnaissance Orbiter now suggests that a lake in a Martian crater had filled from groundwater coming up from below.
This is an important discovery, as it demonstrates that an underground water table had existed on Mars, at least at this location. With such a water table, it is possible for all kinds of interesting biological things to have taken place, underground.
