NASA Mars Rover Spirit May Move Forward By Spinning Its Wheels

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."

The difference is that winter is coming, and the sun gets low on the horizon. We can, if we chose, dig in on one side so that we tilt toward the sun, which means that we will get more solar energy, and so the solar powered rover will survive the winter.

(We've tilted the rover into the sun every winter so far-- if we don't, this will be the first winter we've tried to survive without tilting into the sun)

Actually, Opportunity is examining the damaged heat shield from re-entry, which it just arrived at the other day.
