PASADENA, Calif. - The ground team for NASA's Mars rover Curiosity has switched the rover to a redundant onboard computer in response to a memory issue on the computer that had been active. The intentional swap at about 2:30 a.m. PST today (Thursday, Feb. 28) put the rover, as anticipated, into a minimal-activity precautionary status called "safe mode." The team is shifting the rover from safe mode to operational status over the next few days and is troubleshooting the condition that affected operations yesterday. The condition is related to a glitch in flash memory linked to the other, now-inactive, computer.

Not good! The probability is that they will be able to continue operations after accommodating their operations to whatever problem they diagnose, but it is still "early innings". Better head up the mountain while you can! They've been cooling their heels in this same spot for over a month, now.

Could be radiation effects. Single-event glitch? What is the total gamma dose rate at Mars surface?

Heh. Cf. Wikipedia,
Mars Radiation Environment ExperimentIronically, in the Autumn of 2003 after a series of particularly strong solar flares MARIE started malfunctioning, probably as a result of being exposed to the solar flare's intense blast of particle radiation. The instrument was never restored to working order.

Mars doesn't have much, if any, magnetosphere, so any particle coming from the sun or anywhere can just barrel right in.
Just a single little one or zero needs to be set wrong to upset the whole apple cart.
Imagine there is shielding, but......................

If we're still communicating with them, I'm guessing the restart was not in "Safe Mode," but
"Safe Mode With Networking."Know your start-up options.
