Lunar Take Off Simulator: This simulator is used by scientists at the Langley Research Center ... to help determine human ability to control a lunar launch vehicle in vertical alignment during takeoff from the moon for rendezvous with a lunar satellite vehicle on the return trip to earth. The three-axis chair, a concept which allows the pilot to sit upright during launch, gives the navigator angular motion (pitch, role, and yaw) cues as he operates the vehicle through a sidearm control system. The sight apparatus in front of the pilot's face enables him to align the vehicle on a course toward a chosen star, which will be followed as a guidance reference during the lunar launch. The pilot's right hand controls angular motions, while his left hand manipulates the thrust lever. The simulator is designed for operation inside an artificial planetarium, where a star field will be projected against the ceiling during "flights". The tests are part of an extensive NASA program at Langley in the study of problems relating to a manned lunar mission. (From a NASA Langley, photo release caption.)
