There was one mars rover forget the name that used it's lander as a communications relay. When that died it's rover would power up, make a 360 degree circuit around the lander waiting for relayed instructions, then when it didn't get any shut back down, repeating the process daily "Like an orphaned calf circling the dead body of it's mother" as one writer put it.

Heady stuff to imagine that we are controlling devices on other planets when barely a century ago we had just figured out how to build a workable flying machine.
