The plucky little Curiosity rover that's been rolling around Mars' gale crater, finding signs of ancient water and snapping photos, is marking the end of its first year on the red planet today. It feels like only yesterday that Curiosity rode its daring rocket-parachute-sky crane contraption down to the surface. But it wasn't yesterday, it was August 5, 2012.
Wait, you say, didn’t Curiosity land on Mars in August of 2012? Shouldn’t we still be approaching the TWO-year anniversary of the MSL mission? Well, yes, here on Earth, but on Mars a year is 1.8808 Earth-years long — that’s 686.9 Earth days to a single Martian year! So from landing day August 5 (August 6 UTC) 2012, 686.9 days Earth days (i.e., one Martian year) later is June 24, 2014.
NASA's Jet Propulsion Laboratory has put together a highlight reel of what Curiosity has been up to over the past year. Just imagine all the things you could do in a year if you could make it nearly twice as long?
