Astronaut Edwin Aldrin prepares to deploy EASEP on surface of moon

Astronaut Edwin E. Aldrin Jr., lunar module pilot, moves toward a position to deploy two components of the Early Apollo Scientific Experiments Package (EASEP) on the surface of the Moon during the Apollo 11 extravehicular activity. The Passive Seismic Experiments Package (PSEP) is in his left hand; and in his right hand is the Laser Ranging Retro-Reflector (LR3). Astronaut Neil A. Armstrong, commander, took this photograph with a 70mm lunar surface camera.
