Remembering Apollo
Remembering Apollo 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. Graham Ryder, Lunar and Planetary Science Institute
