S72-30694 (28 Jan. 1972) --- Astronauts John W. Young, left, Apollo 16 commander, and Charles M. Duke Jr., lunar module pilot, prepare to begin a simulated traverse in a training area at the Kennedy Space Center (KSC). The fifth National Aeronautics and Space Administration (NASA) Apollo lunar landing mission is scheduled to land in the mountainous highlands region near the crater Descartes to explore the area for a three-day period. Among the experiments to fly on Apollo 16 is the soil mechanics (S-200) experiment or self-recording penetrometer, a model of which is held here by Duke. A training model of the Lunar Roving Vehicle (LRV) is parked between the two crew men. Astronaut Thomas K. (Ken) Mattingly II is prime crew command module pilot for the mission.
