Rescue Gemini
A version of Gemini was proposed for rescue of crews stranded in Earth orbit. This version, launched by a Titan 3C, used a transtage for manoeuvring. The basic Gemini re-entry module was extended to 120 inches (3.05 m) diameter to provide a passenger compartment for the rescued crew. The same concept would eventually be used for Big Gemini.

American manned rescue spacecraft. Study 1966. A version of Gemini was proposed for rescue of crews stranded in Earth orbit. This version, launched by a Titan 3C, used a transtage for maneuvering.

The basic Gemini reentry module was extended to 120 inches (3.05 m) diameter to provide a passenger compartment for up to three rescued crew. The same concept would eventually be used for Big Gemini.

Gross mass: 12,300 kg (27,100 lb).
Unfuelled mass: 6,300 kg (13,800 lb).
Height: 11.00 m (36.00 ft).
Thrust: 71.17 kN (15,999 lbf).
Specific impulse: 311 s.

  • Rescue In the early 1960's, in the hey-day of the X-20 Dynasoar, it seemed that the US military would naturally keep building military aerospacecraft that would just keep going higher and faster. It was also supposed that the pilot would have to be given the equivalent of an ejection seat - some means of bailing out of the spacecraft in case of catastrophic failure or enemy attack. 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...

Associated Propellants
  • N2O4/UDMH Nitrogen tetroxide became the storable liquid propellant of choice from the late 1950's. Unsymmetrical Dimethylhydrazine ((CH3)2NNH2) became the storable liquid fuel of choice by the mid-1950's. Development of UDMH in the Soviet Union began in 1949. It is used in virtually all storable liquid rocket engines except for some orbital manoeuvring engines in the United States, where MMH has been preferred due to a slightly higher density and performance.
