Those holes in the wheels, on the far side of the wheel in this image, form the rover’s visual odometry, spelling JPL in Morse code.
Curiosity is downloading thousands of pictures of itself and its surroundings, completing a few new checkouts before she rolls toward a rock outcropping called Glenelg, probably sometime in the next couple Mars-weeks.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
