NASA's Curiosity Rover temporarily switches 'brains' - NASA's Curiosity rover has switched to its second computer after a technical issue prevented the probe from storing science data. The switch will enable engineers to do a detailed diagnosis of the issue, the US space agency said in a statement. Like many NASA spacecraft, Curiosity was designed with two, redundant computers -- in this case, referred to as a Side-A and a Side-B computer -- so that it can continue operations if one experiences a glitch.
