Meteorite? Rover antics? Elvis?
All of these theories are on the table when it comes to the mysterious rock that has appeared on Mars. When scientists working with the Mars Opportunity Rover compared two photos — one taken in late December and one on January 8 — they noticed the rock, which apparently appeared right in front of the rover at some point within a 12-day window.
The rover’s lead scientist, Steve Squyres, announced the finding at a 10-year anniversary event hosted by NASA’s Jet Propulsion Laboratory, celebrating a decade of roving on the red planet: “It’s about the size of a jelly doughnut. 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.”
