Atlas agena payloaf12/8/2023 Following a Lockheed briefing on pulse-code-modulation (PCM) instrumentation systems, representatives of Goddard Space Flight Center and Manned Spacecraft Center (MSC) formed a small working group to discuss the feasibility of making the Gemini telemetry system a full PCM system. Small working group to discuss the feasibility of making the Gemini telemetry system a full PCM system. Small working group to discuss the feasibility of making the Gemini telemetry system a full PCM system.Lockheed's planned program included: propulsion system optimization studies, a multiple-restart development program for the primary propulsion system, and a development program for the secondary propulsion system. Īt an Atlas-Agena coordination meeting, Lockheed presented a comprehensive description of its proposed propulsion development plans for the Gemini-Agena. Propulsion development plans for the Gemini-Agena.Flight missions remained unchanged from the January analysis. The first unmanned qualification flight was still scheduled for late July or early August 1963, but the second (manned) flight was now planned for late October or early November 1963 and the first Agena flight for late April or early Many 1964, with remaining flights to follow at two-month intervals, ending in mid-1965. No problems beset launch vehicle development, but the schedule allowed little contingency time for unexpected problems. A key feature of engineering development for the Gemini program was the use of a number of test articles, the lack of which had sometimes delayed the Mercury program although constructing these test articles might cause some initial delay in Gemini spacecraft construction, the data they would provide would more than compensate for any delay. Procurement of the Agena target vehicle had been initiated so recently that scope for analysis in that area was limited. Unlike the first, it considered launch vehicles as well as the spacecraft. Manned Spacecraft Center issued its second analysis of the Gemini program schedule.Marshall also reported the expected delivery of a qualified multiple-restart main engine in 50 weeks, an improvement that removed this development requirement as the pacing item in Agena scheduling. SSD assigned the Gemini Agena target vehicle program to its Ranger Launch Directorate, which was responsible for programs using Agena vehicles. Air Force Space Systems Division (SSD) was to contract with Lockheed for 11 target vehicles. Marshall Space Flight Center delivered an Agena procurement schedule (dated March 8) to Gemini Project Office. Marshall Space Flight Center delivered an Agena procurement schedule (dated March 8) to Gemini Project Office.The transponder, a combined receiver and transmitter designed to transmit signals automatically when triggered by an interrogating signal, was located in the Agena target vehicle. Purpose of the rendezvous radar, sited in the recovery section of the spacecraft, was to locate and track the target vehicle during rendezvous maneuvers. Westinghouse Electric Corporation, Baltimore, Maryland, received a $6.8 million subcontract from McDonnell to provide the rendezvous radar and transponder system for the Gemini spacecraft. Rendezvous radar and transponder system for the Gemini spacecraft.The first Atlas-Agena launch under this program was expected to take place on or about March 15, 1964. Regularly scheduled meetings were planned to resolve technical and management problems between MSC and Marshall. Marshall was to spend no more than $2 million, however, until a Statement of Work had been made definite. Manned Spacecraft Center (MSC) suballotted $5.2 million to Marshall Space Flight Center for procuring Atlas-Agena vehicles for Project Gemini.
