Astronaut Frank Borman at the controls of the Visual Docking Simulator. From A.W. Vogeley, "Piloted Space-Flight Simulation at Langley Research Center," Paper presented at the American Society of Mechanical Engineers 1966 Winter Meeting, New York, NY, November 27-December 1, 1966. "This facility was [later known as the Visual-Optical Simulator.] It presents to the pilot an out-the-window view of his target in correct 6 degrees of freedom motion. The scene is obtained by a television camera pick-up viewing a small-scale gimbaled model of the target." "For docking studies, the docking target picture was projected onto the surface of a 20-foot-diameter sphere and the pilot could, effectively, maneuver into contract. this facility was used in a comparison study with the Rendezvous Docking Simulator - one of the few comparison experiments in which conditions were carefully controlled and a reasonable sample of pilots used. All pilots preferred the more realistic RDS visual scene. The pilots generally liked the RDS angular motion cues although some objected to the false gravity cues that these motions introduced. Training time was shorter on the RDS, but final performance on both simulators was essentially equal. " "For station-keeping studies, since close approach is not required, the target was presented to the pilot through a virtual-image system which projects his view to infinity, providing a more realistic effect. In addition to the target, the system also projects a star and horizon background. "

Multiple exposure of Gemini rendezvous docking simulator. Francis B. Smith wrote in his paper "Simulators for Manned Space Research," "The rendezvous and docking operation of the Gemini spacecraft with the Agena and of the Apollo Command Module with the Lunar Excursion Module have been the subject of simulator studies for several years. [This figure] illustrates the Gemini-Agena rendezvous docking simulator at Langley. The Gemini spacecraft was supported in a gimbal system by an overhead crane and gantry arrangement which provided 6 degrees of freedom - roll, pitch, yaw, and translation in any direction - all controllable by the astronaut in the spacecraft. Here again the controls fed into a computer which in turn provided an input to the servos driving the spacecraft so that it responded to control motions in a manner which accurately simulated the Gemini spacecraft." A.W. Vogeley further described the simulator in his paper "Discussion of Existing and Planned Simulators For Space Research," "Docking operations are considered to start when the pilot first can discern vehicle target size and aspect and terminate, of course, when soft contact is made. ... This facility enables simulation of the docking operation from a distance of 200 feet to actual contact with the target. A full-scale mock-up of the target vehicle is suspended near one end of the track. ... On [the Agena target] we have mounted the actual Agena docking mechanism and also various types of visual aids. We have been able to devise visual aids which have made it possible to accomplish nighttime docking with as much success as daytime docking." -- Published in Barton C. Hacker and James M.

Astronaut Alan Shepard (right) was one of 14 astronauts, 8 NASA test pilots, and 2 McDonnell test pilots who took part in simulator studies. Shepard flew the simulator on November 14, 1963. A.W. Vogeley wrote: "Many of the astronauts have flown this simulator in support of the Gemini studies and they, without exception, appreciated the realism of the visual scene. The simulator has also been used in the development of pilot techniques to handle certain jet malfunctions in order that aborts could be avoided. In these situations large attitude changes are sometimes necessary and the false motion cues that were generated due to earth gravity were somewhat objectionable; however, the pilots were readily able to overlook these false motion cues in favor of the visual realism." Roy F. Brissenden noted that: "The basic Gemini control studies developed the necessary techniques and demonstrated the ability of human pilots to perform final space docking with the specified Gemini-Agena systems using only visual references. ... Results... showed that trained astronauts can effect the docking with direct acceleration control and even with jet malfunctions as long as good visual conditions exist.... Probably more important than data results was the early confidence that the astronauts themselves gained in their ability to perform the maneuver in the ultimate flight mission." Shepard commented: "I had the feeling tonight - a couple of times - that I was actually doing the space mission instead of the simulation. As I said before, I think it is a very good simulation." Shepard also commented on piloting techniques. Most astronauts arrived at this same preferred technique: Shepard: "I believe I have developed the preferred technique for these conditions and the technique appeared to me to be best was to come in slightly above the target so that I was able to use the longitudinal marks on the body of the target as a reference, particularly for a lateral translation and, of course, I used the foreshortening effect for a vertical translation, and this appeared to give me the best results. By that I mean the least number of control motions and the lowest fuel usage and the best end techniques, or the best end conditions, I should say." Engineer: "When you started to run you didn't start thrusting immediately I don't believe. It looked like you started working on your attitudes, then started closing in." Shepard: "That is correct. I did that because I felt that I wanted to get the X-axis translation in the most effective vector and for minimum fuel usage that wouldn't introduce any other lateral or vertical offsets that did not already exist." -- Published in Barton C.

Astronaut Virgil "Gus" Grissom at the controls of the Visual Docking Simulator. From A.W. Vogeley, "Piloted Space-Flight Simulation at Langley Research Center," Paper presented at the American Society of Mechanical Engineers 1966 Winter Meeting, New York, NY, November 27-December 1, 1966. "This facility was [later known as the Visual-Optical Simulator.] It presents to the pilot an out-the-window view of his target in correct 6 degrees of freedom motion. The scene is obtained by a television camera pick-up viewing a small-scale gimbaled model of the target." "For docking studies, the docking target picture was projected onto the surface of a 20-foot-diameter sphere and the pilot could, effectively, maneuver into contract. this facility was used in a comparison study with the Rendezvous Docking Simulator - one of the few comparison experiments in which conditions were carefully controlled and a reasonable sample of pilots used. All pilots preferred the more realistic RDS visual scene. The pilots generally liked the RDS angular motion cues although some objected to the false gravity cues that these motions introduced. Training time was shorter on the RDS, but final performance on both simulators was essentially equal. " "For station-keeping studies, since close approach is not required, the target was presented to the pilot through a virtual-image system which projects his view to infinity, providing a more realistic effect. In addition to the target, the system also projects a star and horizon background. "

Move crews at NASA’s Michoud Assembly Facility in New Orleans guide the Inter-Stage Simulator (ISS) to the Michoud deep water port on Monday, Sept. 19 in preparation for transportation by barge to the agency’s Stennis Space Center near Bay St. Louis, Mississippi. Once it arrives at Stennis, the simulator will be lifted into the B2 Test Stand, where it holds the Exploration Upper Stage (EUS) in place and acts as a thrust takeout. ISS protects the lower portion of the EUS from environmental elements during its Green Run tests. The term “green” refers to the new hardware, and “run” refers to operation all the components together for the first time. During tanking and launch for its future mission, the lower portion is shrouded in a flight interstage. EUS is part of the SLS Block 1B configuration. The more powerful configuration of the SLS rocket will provide in-space propulsion to send astronauts in NASA’s Orion spacecraft and 40% more cargo mass on a precise trajectory to the Moon. Through the Artemis missions, NASA will land the first woman and the first person of color on the Moon to pave the way for a sustainable presence on the Moon and future missions beyond.
