Terrestrial Garbage On Mars
An anonymous reader writes "The garbage left behind by the twin Mars rovers was highlighted this week by the close-up view in panorama of the Spirit rovers' heatshield. Not including the various Viking, Pathfinder and some crippled probes, the human contribution of rover hardware to the martian surface now includes a few odd nicknacks, parachutes, heatshields, back shell,landing petals and many wheel tracks. It may be September before the rovers themselves become part of the red planet's debris field."
Actually, it was a reference to Space Balls :)
