JPL has put together a touching little momento to the Mars Rover Opportunity. The determined little robot took a picture at the end of each leg of its three-year journey over 13 miles of martian terrain. JPL stiched those images into a time-lapse, paired with an audio representation of accelerometer data gathered by the robot, which helps you know if that day's wanderings were bumpy or smooth for Opportunity. It's a bit of a touching experience, so make sure you have some tissue handy when you watch the video, embedded below. Oh, and Mars: we'll be seeing each other again soon, so don't get too comfortable up there.
