When was gemini 12

Lovell, Jr. Aldrin, Jr. Mission Summary: Launch was originally scheduled for November 9, but was postponed on November 8, when a power supply in the Gemini-Titan II secondary autopilot malfunctioned.

The suspect equipment was replaced, and the launch was rescheduled for November 10, Another malfunction in the secondary autopilot of the Gemini-Titan II was detected during testing on November 9, which resulted in an additional one day delay in the launch as the suspect equipment was replaced and tested.

As the Gemini 12 spacecraft began its approach to the GATV, the radar system used as a rendezvous tool failed, and the crew completed a manual rendezvous that was achieved at a mission elapsed time of 3 hours, 46 minutes.

As had been the case during Gemini 10 and Gemini 11, the mated spacecraft were to have been boosted to a higher altitude through the firing of the GATV multiple-start engine thrusters. However, an attempt to boost the mated spacecraft to a higher altitude was not attempted due to problems in the GATV Primary Propulsion System PPS that were detected when it was launched.

At a mission elapsed time of 19 hours, 29 minutes the hatch was opened, allowing astronaut Aldrin to stand in his seat with his upper body outside the Gemini 12 spacecraft.

Flight : Gemini Air Force Space Systems Division SSD recommended a Gemini Agena launch on a nonrendezvous mission to improve confidence in target vehicle performance before undertaking a rendezvous mission. Gemini Project Office GPO rejected this plan, regarding it as impractical within current schedule, launch sequence, and cost restraints.

First Agena D for the Gemini program. Following minor retrofit operations, the vehicle, now designated Gemini Agena target vehicle , entered the manufacturing final assembly area at the Lockheed plant on May There began the conversion of the Agena D into a target vehicle for Gemini rendezvous missions. Major modifications were installation of a target docking adapter supplied by McDonnell , an auxiliary equipment rack, external status displays, a secondary propulsion system, and an L-band tracking radar.

Final assembly of Gemini Agena target vehicle -. Spacecraft : Gemini Agena Target Vehicle. Lockheed completed the modification and final assembly of Gemini Agena target vehicle and transferred it to systems test complex C at the Lockheed plant. Lockheed began the task of hooking the vehicle up for systems testing the next day, September Minor anomalies required portions of the test to be rerun.

The vehicle was shipped November Primary test objective was verifying the operational capabilities of the GATV during actual firing of the primary and secondary propulsion systems. The test simulated a full 20,second mission, including multiple firings of both the primary and secondary propulsion systems and transmission of operational data in real time to two PCM pulse-code-modulated telemetry ground stations, one at the test site and one in Sunnyvale.

Major test anomaly was a series of command programmer time-accumulator jumps, seven of which totaled 77, seconds. The vehicle was removed from the test stand on February 1 and returned to Sunnyvale. After a brief stopover in systems test complex C, the vehicle was transferred to the anechoic chamber for elecromagnetic interference and radio-frequency-interference tests.

Gemini Agena target vehicle completed electromagnetic compatibility tests in the anechoic chamber at Sunnyvale. It remained in the chamber, however, until March 17 while Lockheed verified the corrective action that had been taken to eliminate programmer time-accumulator jumps and telemetry synchronization problems.

The vehicle was then transferred to systems test complex C for final Vehicle Systems Tests on March Six days were scheduled for vehicle modifications before beginning final systems tests. Flight : Gemini 12 , Gemini 3. Gemini Agena target vehicle GATV completed vehicle systems testing with a final simulated flight.

The vehicle was disconnected from the test complex on May 14, and data analysis was completed May Flight : Gemini 12 , Gemini 6. This was because First Article Configuration Inspection completed May 26 showed the vehicle not to be flightworthy as required by the contract. Discrepancies remaining on Gemini Agena target vehicle cleared.

The major portion of discrepancies remaining from the First Article Configuration Inspection FACI of Gemini Agena target vehicle in June were cleared; that had not been applied against the acceptance document DD remained.

Disassembly and inspection of Gemini Agena target vehicle to determine the extent of refurbishment. Air Force Space Systems Division authorized Lockheed to begin the disassembly and inspection of Gemini Agena target vehicle to determine the extent of refurbishment needed.

The vehicle was stripped down to its major structural components to expose all areas of possible contamination.

Gemini launch vehicle GLV 12 in assembly -. Flight : Gemini 11 , Gemini Flight : Gemini 10 , Gemini 11 , Gemini Gemini Program Manager Charles W. The task force's function was to see that GATV reached a flightworthy condition on time and as economically as possible. The reassembly plan provided an operational base line as well as guidelines for reassembling the vehicle, which was completely disassembled down to the level of riveted or welded parts.
