Oh noes! The Mars rover Spirit has sunk nearly to its axles in soft ground. Will this be the end of the intrepid little probe? Nobody's sure, but they're definitely trying to figure out if it can dig itself out. It'll be a helluva long time before a tow truck can get out there otherwise.
Even if this is the end, at 5 years and change for a robot expected to only live...what, 90 days?
NASA--and therefore the US taxpayer--has definitely gotten its money's worth!
