Mars' Atmospheric Chemistry is Still Kicking, Says Rover Data

Mars is a dead world. It may have once been home to water and life, but experts have been fairly certain that the Red Planet is now nothing more than a grave frozen in time - a snapshot of what would happen to Earth if it was ever stripped of its atmospheric protections. However, new data from NASA's Curiosity rover has revealed that the planet is still a bit active, at least on a chemical level.
