Remembering Apollo On the Cover: The Genesis Rock was one of the great prizes returned to Earth by project Apollo. Here we show a magnified view of individual crystals within the rock. Analysis of this piece of anorthosite fixed its age at about 4.4 billion years—a rare find in a solar system on 4.6 billion years old. Scientists infer that the Genesis Rock formed from the original magma ocean that once covered the surface of the forming Moon.
