Condition of rovers left on the moon
Pretty damn hard to make things that last
Except the batteries on that rover are long dead. Many, if not all, of the plastic and paper insulators exposed to vacuum are now brittle and broken. All labels or painted surfaces are likely bleached white. Differential expansion during lunar daylight cycles has likely snapped a few things here and there too. Fifty years of exposure to static electric charges on the moon has put lunar dust in all sorts of places it doesn't belong.
