Astronaut Charles Duke examines surface of boulder at North Ray crater

AS16-116-18649 (23 April 1972) --- Astronaut Charles M. Duke Jr., lunar module pilot of the Apollo 16 lunar landing mission, examines closely the surface of a large boulder at North Ray Crater during the third Apollo 16 extravehicular activity (EVA) at the Descartes landing site. This picture was taken by astronaut John W. Young, commander. Note the chest-mounted 70mm Hasselblad camera. While astronauts Young and Duke descended in the Apollo 16 Lunar Module (LM) "Orion" to explore the Descartes highlands landing site on the moon, astronaut Thomas K. Mattingly II, command module pilot, remained with the Command and Service Modules (CSM) "Casper" in lunar orbit.
