The last four Gemini missions carried this type of film magazine for use with a Maurer 70mm camera. The camera was used for scientific photography. The equipment available for these experiments was extensive and included lenses of different focal lengths, special filters, and extra film magazines, which increased the types and amount of photographic work astronauts could do in space.
NASA transferred this film magazine to the Museum in 1971.
