The 16mm Data Acquisition Camera (DAC) was manufactured by J. A. Maurer Company specifically for the Apollo program. Used in both the command and lunar modules, the DAC was tested on Apollo 8, the first circumlunar mission, and again on Apollo 9, the first test of the lunar module. DACs were an essential piece of equipment that aided in the recording of EVAs, landing and lunar approach, and technical procedures such as the undocking and redocking of the lunar module.
