"“So my best guess for this rock … is that it’s something that was nearby,” said Squyres. “I must stress that I’m guessing now, but I think it happened when the rover did a turn in place a meter or two from where this rock now lies.”
Opportunity’s front right steering actuator has stopped working, so Squyres identified that as the possible culprit behind the whole mystery."
Reading a lot of speculation, but this seems pretty plausible - without the need for anything crazy like aliens, subterranean oozing or a rock falling from space and just so happening to land in front of the rover... But, Hey! Perhaps it is martian-cow dung afterall!
