And he credits another WUSTL professor for the fact that the astronauts even collected the moon rocks in the first place.
Randy L. Korotev, Ph.D., a research professor in the Department of Earth and Planetary Sciences in Arts & Sciences, has studied lunar samples and their chemical compositions since he was an undergraduate at the University of Wisconsin and "was in the right place at the right time" in 1969 to be a part of a team to study some of the first lunar samples.
"We know even more now and can ask smarter questions as we research these samples," says Korotev, who is mainly interested in studying the impact history of the moon, how the moon's surface has been affected by meteorite impacts and the nature of the early lunar crust.
"There are still some answers, we believe, in the Apollo 11 mission.
