All about the laser (and microphone) atop Mars 2020, NASA's next rover

NASA is sending a new laser-toting robot to Mars. But unlike the lasers of science fiction, this one is used for studying mineralogy and chemistry from up to about 20 feet (7 meters) away. It might help scientists find signs ...
