Gemini Transport
Gemini Transport version proposed as a Gemini program follow-on. With the extended re-entry module, this is the ancestor of the Big Gemini spacecraft proposed in the late 1960's.

American logistics spacecraft. Study 1963. This Gemini Transport version was proposed as a Gemini program follow-on in 1963. With the extended reentry module, this was the ancestor of the Big Gemini spacecraft of the late 1960's.

In 1962 NASA funded studies with several contractors on Operations and Logistics for Space Stations. McDonnell's study was dated 20 March 1963 and proposed three alternatives, all of which could be boosted by either a Titan 3M or Saturn IB Launch Vehicle, and all of which would be equipped with aft-mounted docking systems:

  • Two-crew Gemini, relatively unmodified, with a cargo module
  • Modified Gemini with a stretched re-entry vehicle (later fully developed into the Big-Gemini)
  • New winged spaceplane, capable of accommodating two crew plus four passengers

Crew Size: 2.

Gross mass: 18,500 kg (40,700 lb).
Height: 9.73 m (31.92 ft).

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...
