Mars Curiosity rover to continue roving after technical glitch

Nasa engineers have overcome a computer glitch that shut down the space agency's car-sized Mars rover, Curiosity, earlier this week.
The $2.5bn rover went into a precautionary "safe mode" on Sunday, when a command file failed a check by protective software on board the mobile science laboratory.
Richard Cook, at Nasa's Jet Propulsion Laboratory, said the fix was "a very straightforward matter to deal with" and was resolved by deleting the offending file. He said engineers knew how to prevent the glitch from happening again.
The rover has two computers it can switch between: the main A side, and a B side that acts as a backup. The latest computer problem arose when the rover was operating on the B side after an unrelated memory fault knocked out its A side.
