Mystery Rock suddenly appears near Mars Rover!

Very weird, Mars Rover is causing a stir with a picture of mysterious rock that suddenly appears from out nowhere.

You can clearly see in the first photo that there is just bare bedrock, then in another photo taken some time later a fist sized rock is clearly seen, but where did it come from!?

Comparison of two raw Pancam photographs from sols 3528 and 3540 clearly shows the mystery rock.

After a decade of exploring the Martian surface, the scientists overseeing veteran rover Opportunity thought they’d seen it all. That was until a rock mysteriously “appeared” a few feet in front of the six wheeled rover a few days ago.

News of the errant rock was announced by NASA Mars Exploration Rover lead scientist Steve Squyres of Cornell University at a special NASA Jet Propulsion Laboratory “10 years of roving Mars” event at the California Institute of Technology (Caltech), Pasadena, Calif., on Thursday night.

In a comparison of recent photographs captured by the rover’s panoramic camera, or Pancam, on sol 3528 of the mission, only bare bedrock can be seen. But on sol 3540, a fist-sized rock had appeared (raw Pancam images can be found in the mission archive). MER scientists promptly nicknamed the object “Pinnacle Island.”

“It’s about the size of a jelly doughnut,” Squyres told Discovery News. “It was a total surprise, we were like ‘wait a second, that wasn’t there before, it can’t be right. Oh my god! It wasn’t there before!’ We were absolutely startled.”

But the rover didn’t roll over that area, so where did Pinnacle Island come from?

Only two options have so far been identified as the rock’s source: 1) The rover either “flipped” the object as it maneuvered or, 2) it landed there, right in front of the rover, after a nearby meteorite impact event. The impact ejecta theory, however, is the least likely of the two.

“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.
