At the time the USAF was looking at an orbital space station that would function as a spy satellite. It would have a large telescope to see targets on earth. At the time such cameras used film. The Man Orbital Laboratory or MOL, was planed to use a military version of the Gemini capsule. This was referred to a "blue" Gemini as the USAF had blue dress uniforms. They were looking for an alternative that could land on a runway at a base to make retuning the film faster and with less chance of it getting lost. The DYNASOAR would be launched on a titan rocket, dock at the MOL, then separate and reenter with the astronauts and the film. It would glide back to the runway at an AFB and land.
When NASA took over manned space flight the USAF MOL program and military Gemini capsule projects were canceled. The DYNASOAR project continue to study the flight of lifting bodies.
