Overall view of the lunar communications relay unit (LCRU). The LCRU was an electronics box which allowed two-way communication of voice, television, and telemetry between the astronauts and ground controllers during an EVA. The Smithsonian has a page on the LCRU, and the Apollo Lunar Surface Journal has a crew training manual. | ||||
