Back at the end of last month, the Mars rover Curiosity marked its 1,000th "sol" on the red planet. Sol was the name given to a Martian day, which is a little bit longer than ours.

Of course, what's not shown is how far Curiosity had to travel to get to Mars. But it's hard to leave tracks in space.
