NASA is sending a rocket to Mars this morning.  The Atlas Five rocket will be carrying the Perseverance rover and a small helicopter to Mars.  The car-sized robotic rover will search for evidence of past life on the planet, and will take videos and photographs.  It also has two microphones, and will be the first spacecraft to record sounds on another planet.  The small helicopter is a four-pound ‘Marscopter’ that, if it works, will be the first powered flight on another planet.
