This space paper model is the Manned Orbiting Laboratory (MOL) with Gemini-B, created by Godai, and the scale is in 1:80. The Manned Orbiting Laboratory was part of the United States Air Force's manned spaceflight program, a successor to the cancelled Boeing X-20 Dyna-Soar military reconnaissance space plane project.
The project was developed from several early Air Force and NASA concepts of manned space stations to be used for reconnaissance purposes. MOL evolved into a single-use laboratory, with which crews would be launched on 40-day missions and return to Earth using a Gemini-B spacecraft, derived from NASA's Gemini program.
