NASA Mars Rover Spirit May Move Forward By Spinning Its Wheels 175
coondoggie writes "As NASA celebrates its Mars rover Spirit's sixth anniversary exploring the red planet, it is hunting for a way to keep the machine, which is mired in a sand trap, alive to see a seventh year. On its Web site, the space agency this week noted there may indeed be such an option. That option would be spinning the wheels on the north side of Spirit, letting it dig in deeper in the Martian sand but at the same time improving the tilt of the rover's solar panels toward the Sun."
