Maurer data acquisition cameras like this high fidelity mockup documented technical aspects of missions. Astronauts used a motion picture camera like this, along with its large battery, while exploring the lunar surface on their lunar roving vehicle. The moving images were later viewed back on Earth to determine how well the equipment worked and how mission requirements were accomplished.
This camera was transferred from NASA to the Museum in 1975.
This object is on display in James S. McDonnell Space Hangar at the Steven F. Udvar-Hazy Center in Chantilly, VA.
