In an isolated area of the Manned Spacecraft Center's Lunar Receiving Laboratory, geologists Don Morrison (left) and Fred Horz flank University of Texas geologist/professor William (Bill) Muehlberger as the three look at a "special" rock brought back from the moon recently by the Apollo 16 astronauts. Lunar sample 61016, better known as "Big Muley," is a large breccia sample, the largest moon rock returned by any Apollo crew, which is named after Muehlberger, the Apollo 16 field geology team leader.
