NASA's Goddard Space Flight Center and the Lunar Reconnaissance Orbiter present to you a short, narrated Science on a Sphere show depicting the evolution of our moon - all the way from when it was just a ball of magma orbiting the Earth. See the large impacts that formed the basins of the moon, watch as lava seeps out and cools to form the dark-colored maria, and observe how thousands of crater impacts made the moon look like it does today!
