Manned Orbiting Laboratory - History

History

There was one test flight of an MOL mockup that was built from a Titan II propellant tank. The Gemini 2 spacecraft was re-flown on a 33-minute sub-orbital test flight. After the Gemini was separated for its sub-orbital reentry, the MOL mockup continued on into orbit and released three satellites. A hatch was installed in the Gemini 2 heat shield to provide access to the MOL and was tested in the sub-orbital reentry. The test flight was launched by the USAF on November 3, 1966 at 13:50:42 UTC on launch vehicle Titan IIIC-9 from LC-40 at Cape Canaveral Air Force Station. The Gemini 2-MOL space capsule was recovered near Ascension Island in the South Atlantic by the USS La Salle.

The MOL was planned to use a helium-oxygen atmosphere. It used a Gemini B spacecraft as a reentry vehicle. The crew were to be launched with the Gemini B and MOL, and returned to Earth in the Gemini B. They would conduct up to 40 days of military reconnaissance using large optics, cameras, and side-looking radar.

The USAF Astronaut Maneuvering Unit (AMU) was developed for the MOL project. NASA chief astronaut Deke Slayton later speculated in his autobiography that the AMU may have been developed for MOL because the Air Force "thought they might have the chance to inspect somebody else's satellites."

In response to the announcement of the MOL, the USSR commissioned the development of its own military space station, Almaz. Three Almaz space stations flew as Salyut space stations, and the program also developed a military add-on used on Salyut 6 and Salyut 7.

In 2005, two MH-7 training space suits from the MOL program were discovered in a locked room in the Launch Complex 5/6 museum on Cape Canaveral.
