American manned spacecraft. Study 1965. A McDonnell concept for using Gemini for extended duration missions. The basic Gemini would dock with an Agena upper stage.

Between the docking collar and the Agena was an orbital shelter where the crew would live and work for weeks at a time.

The crew would transfer from the Gemini to the miniature space station via an inflatable airlock.

Characteristics

Crew Size: 2.

Height: 16.90 m (55.40 ft).

  • US Space Stations Wernher von Braun brought Noordung's rotating station design with him from Europe. This he popularized in the early 1950's in selling manned space flight to the American public. By the late 1950's von Braun's team favoured the spent-stage concept - which eventually flew as Skylab. By the mid-1960's, NASA was concentrating on modular, purpose-built, zero-G stations. These eventually flew as the International Space Station. More...

Associated Launch Vehicles
  • Titan American orbital launch vehicle. The Titan launch vehicle family was developed by the United States Air Force to meet its medium lift requirements in the 1960's. The designs finally put into production were derived from the Titan II ICBM. Titan outlived the competing NASA Saturn I launch vehicle and the Space Shuttle for military launches. It was finally replaced by the USAF's EELV boosters, the Atlas V and Delta IV. Although conceived as a low-cost, quick-reaction system, Titan was not successful as a commercial launch vehicle. Air Force requirements growth over the years drove its costs up - the Ariane using similar technology provided lower-cost access to space. More...
