Spirit Mars Rover In ‘Drive Or Die’ Situation

NASA’s Spirit Mars rover has wrapped up exploration of a baffling feature called “Home Plate” but now faces the onset of martian winter while dealing with dropping power levels and fighting a balky right front wheel.
“Our current focus is to drive like hell … and try to get [Spirit] to safe winter havens before the power situation gets really bad,” said Steve Squyres, lead Mars Rover Exploration scientist at Cornell University.
