Long-lived Mars Opportunity rover sets off-world driving record

That Rover is amazing. She was supposed to last for 90 sols. If everything else only worked as well.

Apparently, Opportunity was only intended to drive half a mile and it has now done 25 - strange that GM can't manage that sort of reliability here on earth

NASA is going to reformat Opportunity's memory. She uses a chip that was old and slow even when she was built (3035?). It was space tested, and reliable so JPL used it.
They also had to reboot Spirit after she landed.

Curiosity has a bad wheel.
