For more than forty years, NASA missions have explored Mars, the Red Planet, with orbiters, landers and rovers.  It's the planet most like our own with dust devils, giant dormant volcanoes and a thin atmosphere. Could we go and someday live there?  By 2024, NASA plans to be going back to the moon and using a new gateway there to fly humans to Mars. Join Solar System Ambassador Pat Monteith as she discusses the Apollo missions, the 50 years since, and the plans to return to the moon and go to Mars.
