Although wintry skies in the St. Louis region didn’t make for ideal viewing conditions Sunday night as the sun, Earth and moon aligned for a total lunar eclipse, the anticipated celestial event still had many people looking skyward. It also sparked renewed interest in human understanding of the moon.

On Friday’s St. Louis on the Air, host Don Marsh talked with space journalist Rebecca Boyle, lunar scientist Brad Jolliff and St. Louis Public Radio’s Eli Chen about the latest in moon research.

Boyle is a freelance writer whose work has recently appeared in outlets including the New York Times and Scientific American. Jolliff is the Scott Rudolph Professor of Earth and Planetary Sciences at Washington University.

This article first appeared in the St. Louis Beacon, Feb. 2, 2010 - The excitement was palpable when four Washington University faculty members got together to explain just why it is so important to go back to the moon and gather new rocks to analyze.

"The moon is like a storage locker of early solar system history," explained Paul Carpenter, director of the microprobe laboratory in earth sciences. "The youngest rock on the moon is older than almost all the rocks on Earth."
