Is there anything cooler than sending a robot to Mars to shoot rocks with lasers? Probably not -- which is why NASA is giving the Curiosity rover the ability to shoot even more rocks with lasers. Okay, technically NASA is giving the Martian rover the ability to choose targets for ChemCam analysis. This is a process that uses a laser and telescopic camera to sort out the chemical composition of Martian rocks. Typically, NASA chooses the targets manually, but a new update will allow the rover to collect data autonomously.
