# PROJECT GEMINI ANALOG RE-ENTRY SIMULATOR NASA FILM 78064

This historic NASA film shows an analog re-entry simulation, made in support of Project Gemini. The concept was to use the simulator to test methods of manual control and techniques for re-entry into the Earth's atmosphere. The six-degree of freedom simulator was developed at the Manned Space Center. The manual control aspects of the Gemini capsule represented an important advance over the Project Mercury capsule, which had no maneuvering capabilities. A primitive cockpit, seen at the 1:41 mark, included a hand controller and a display panel with 8-ball, clock, roll rate command link and all attitude display. The computers used for the simulation were Pace 231-R Analog Computers. These machines were the precursor of modern digital computers. These were made by EAI (Electronics Associates Incorporated). The Pace 231-R computer, was produced in 1961. It worked by using electrical circuits known as operational amplifiers. This model model had 20 such amplifiers. Cables were used to make connections on the 3450-socket (75x46), color-coded patch panel (center). This computer model was used in science and engineering projects in the aerospace, car and nuclear industries. Project Mercury was the first human spaceflight program of the United States running from 1958 through 1963. An early highlight of the Space Race, its goal was to put a human into Earth orbit and return the person safely, ideally before the Soviet Union. Taken over from the U.S. Air Force by the newly created…
