Curiosity suffers software glitch, gets put into safe mode

NASA’s Curiosity rover has been put into “safe mode” after some files which it relies on running have defected. Exactly what damaged the files on the robot’s flash memory is not known.


“We’re still early on in the process,” said project manager Richard Cook.”We have probably several days, maybe a week of activities to get everything back and reconfigured.”

At the moment, the robot is put on temporary hold, while the back-up computer on which it is running now is fully configured, and the investigation on the primary files is concluded.

“We switched computers to get to a standard state from which to begin restoring routine operations,” Mr Cook said.


The main guess researchers have so far is that the damage was caused by cosmic radiation, even though Curiosity was built to survive even harsher conditions.

“The hardware that we fly is radiation-tolerant, but there’s a limit to how hardened it can be. You can still get high-energy particles that can cause the memory to be corrupted. It certainly is a possibility and that’s what we’re looking into.”

The timing is really frustrating, considering how Curiosity has just begun analysing rock samples. Martian samples were “ingested” into the rover’s on-board laboratory last month.


Andrei’s background is in geophysics, and he published his first scientific paper when he was still an undergrad; now, his main focus is on how geology and geophysics can be applied to understand and protect the environment. Feeling that there is a gap between scientists and the general audience, he started ZME Science – and the results are what you see today.
