We chat with Notre Dame geologist and moon expert Clive Neal, who is part of a team that will examine previously sealed lunar samples obtained during the Apollo missions. Learn more about Clive's work. In addition, we look at the School of Architecture's Rome Studies Program as it marks its 50th Anniversary in the Eternal City. Read more about the program.

Producer's note: Clive refers several times to "regolith," which is the powdery, dusty material on the lunar surface.
