As with any good project, there should always be a back up plan. The Curiosity for Mars is no different. The system has a B-Side computer in the event the A-Side computer went down…well guess what, it went down.
There is a theory that cosmic rays affected some of the flash memory on Curiosity causing the A-Side computer to shut down and reboot into Safe Mode.
JPL is currently backup up the A-Side data to the B-Side computer and should reboot by weeks end. Configuration and data transfer can take a while, then of course the verification process of everything done right.
JPL states:
“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.”
