Mars rover Curiosity gets software upgrade, wheel check

NASA engineers have given Mars rover Curiosity a software upgrade and are now checking wear and tear on the one-tonne robot's wheels caused by the rugged Martian surface.


The wheels of Curiosity rover are sustaining damage at an increasing rate, NASA said. "Curiosity is now operating on version 11 of its flight software," said Jim Erickson of NASA's Jet Propulsion Laboratory.

This is the third upgrade version since Curiosity's landing on Mars 16 months ago. Completing the switch from version 10 took about a week, the NASA said.

An earlier switch to version 11 prompted an unintended reboot on November 7 and a return to version 10, but the latest transition went smoothly.
