A year long Curiosity

Just a few quick thoughts.  This week marks the one year anniversary of the Mars Science Laboratory Rover, Curiosity, landing in Gale Crater on the surface of Mars.  A year ago we deposited a ton of nuclear-powered robot on the surface of another world.

Since then it is have been roving, scooping, dusting, vaporizing rocks, and just sciencing the heck out of the red planet.  36,700 images, 76,000 rock-zapping laser shots, and 1.6 kilometers driven so far.  It still has about an 8 km drive to go to get to the lower layers of the 5.5 km tall Mt. Sharp.  Just in it’s first year Curiosity has already a world that looks downright “habitable” in the distant past – spectacularly finding the remains of a pebbled riverbed.

So happy “birthday” to the MSL Rover Curiosity – may there be many more rocks to bother in your future.
