I heard from a lot of people that they really thought it was wonderful. These are informal names, not the certified names. It's quite common for a surface mission to name rocks for some feature that reminds them of something. They weren't all cartoon names. Though the Pathfinder spacecraft stopped sending signals in November, its 23-pound Sojourner land rover may be going in circles or stuck on a rock nearby, still trying to call home, Golombek said.
Nobody knows for sure.
The rover has a variety of safing devices on board. It will try to go around an obstacle. It can tell from the tilt that it should stop and call home. I guess it may be moving. Or it may be just sitting there waiting for instructions.
