In any mission of the Gemini program, the astronauts required critical information about the systems contained on the spacecraft. In the Gemini program this information was bound in looseleaf binders like this one that was carried by Michael Collins into orbit during the Gemini 10 mission, July 18-21, 1966.
Transferred from the NASA Johnson Space Center to the Museum in 1985.
