- This Sunday night, we headed back to Mars: NASA's MAVEN spacecraft fired its six main engines, slowing down enough so it could be captured by the gravity of the red planet and go into orbit.
MAVEN, which stands for Mars Atmosphere and Volatile Evolution, is a distinctly un-sexy name for a project as cool as a sojourn to Mars. But whatever it's called, the probe is on a mission that should be of interest to everyone who likes living on Earth.
