"Don't flip out: I just flipped over to my B-side computer while the team looks into an A-side memory issue," says a message from the Mars rover Curiosity on its NASA Facebook page.
In response to a flash memory issue on the Mars rover Curiosity, NASA's ground team switched the rover to a redundant computer on Thursday, Feb. 28. The rover, with two computers called the A side and B side, is operating on the B-side while the team troubleshoots A-side.

It's really the SRAM soft errors that cause the run-time glitches.

Redundancy is a great think if you can afford it!

I marvel at the ability of engineers to manage computer problems at great distances in hostile environments. I have enough trouble managing mine right in front of me when I have full physical access and the ability to substitute parts. One obvious trait that the NASA ground team has perfected is the ability to plan ahead, think about possible consequences, and craft a careful action plan. Many personal computer repairs go down some dead ends and depend upon physical access to reverse errors and restore functionality.

Long before portable computers, the Beatles anticipated this problem of moving from the "A" side to the "B" side. They released a 45 rpm vinyl record in 1965 with "I'm Down" on one side and "Help" on the flip side!
