When Curiosity's A-side computer experienced a memory issue and failed to send some data back to Earth on Feb. 27, NASA switched on the B-side computer and set to troubleshooting. Thank goodness they had a backup, right?

In an interview with Space.com NASA's Curiosity Project Manager, Richard Cook said that it could take as long as a week to get everything working again. He said the memory glitch could have been caused by a radioactive "high-energy particle," and that they're looking into it.

Here's hoping the little fella recovers swiftly. You never know what could be up there with it.
