Watch Mars Curiosity Wiggle Its Wheels in the Gravel

This futuristic black and white image was taken today by one of the navigation cameras on NASA's Curiosity rover. Engineers at NASA's Jet Propulsion Lab are wiggling front left wheel in the Mars gravel as vehicle gets ready to start out on its first drive soon. The dots on the wheel stand for JPL, because NASA won't let the lab attach its logo. And though the pic is low res, it's inspiringly beautiful. Who knew Ansel Adams was on board?
