S71-19509 (5 Feb. 1971) --- Astronaut Edgar D. Mitchell, lunar module pilot, operates the Active Seismic Experiment's (ASE) thumper during the first Apollo 14 extravehicular activity (EVA) on the moon. Astronaut Alan B. Shepard Jr., commander, walks near deployed components of the Apollo Lunar Surface Experiments Package (ALSEP) in the background. This photograph was taken by an automatic 16mm camera mounted on the Apollo lunar hand tool carrier aboard the Modularized Equipment Transporter (MET). While astronauts Shepard and Mitchell descended in the LM to explore the moon, astronaut Stuart A. Roosa, command module pilot, remained with the Command and Service Modules (CSM) in lunar orbit.
