.....and I guess we do too!!
Last weekend I heard a report on CNN that the two Mars rovers have been up there for a year now. Their solar collectors haven't picked up as much dust as the boys at NASA thought so the two machines have power to spare. They continue roaming the serface of Mars, examining rock outcrops and beaming pictures back to Earth. Not bad for a piece of equipment that was only suppose to last for three months. The guys at NASA know that any one fault can bring an end to it all and that everything they've been receiving is "gravy". But as one NASA tech. put it, "We've long past exceeded our warrenties!"
