Title: Lunar Laser Ranging Reflector, Apollo 14
Caption: A close-up view of a laser ranging retroreflector (LR3) which the Apollo 14 astronauts deployed on the moon during their lunar surface extravehicular activity (EVA) on February 5, 1971. The experiment measures distance between the Earth and the Moon through the use of lasers on Earth aimed at the reflectors. While astronauts Alan B. Shepard Jr., commander, and Edgar D. Mitchell, lunar module pilot, descended in the Lunar Module (LM) to explore the moon, astronaut Stuart A. Roosa, command module pilot, remained with the Command and Service Modules (CSM) in lunar orbit.
