American space suit, operational 1965. This David Clark lightweight suit was developed for long duration project Gemini missions. It was designed to be easily removed during flight and to provide greater comfort than the standard Gemini space suit.

Astronauts Frank Borman and James A. Lovell used suits of this type during their 14 day Gemini VII mission in December 1965.

AKA: Gemini G5C Space Suit; Gemini Lightweight Suit.

  • Space Suits To explore and work in space, human beings must take their environment with them because there is no atmospheric pressure and no oxygen to sustain life. Inside the spacecraft, the atmosphere can be controlled so that special clothing is not needed. But in order to work outside the spacecraft, humans need the protection of a spacesuit. 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...

  • Both stages of Gemini launch vehicle (GLV) 6 were removed from storage and arrived at complex 19 two hours after the launch of Gemini VII. - . Nation: USA. Flight: Gemini 6; Gemini 7. Spacecraft: G5C. Spacecraft No. 6 was returned to complex 19 on December 5. Within 24 hours after the launch of Gemini VII, both stages of GLV-6 were erected, spacecraft and launch vehicle were mated, and power was applied. Subsystems Reverification Tests were completed December 8. The only major problem was a malfunction of the spacecraft computer memory. The computer was replaced and checked out December 7-8. The Simulated Flight Test, December 8-9, completed prelaunch tests. The launch, initially scheduled for December 13, was rescheduled for December 12.
