Brother Bob Macke SJ is the curator of meteorites at the Vatican Observatory, and during his research measuring meteorite physical properties he has probably handled as many rocks from outer space as anyone alive today. Other astronomers may claim to study stars and planets, but mostly all they touch are photons; Bob has handled actual stuff from space, from stellar dust at Washington University in St. Louis to moon rocks at the Johnson Space Center in Houston. Guests: - Br.
