S81-33963 (July 1981) --- Mission specialist/astronaut Sally K. Ride and Dale E. Moore of the flight control division?s electrical, mechanical and environmental systems branch take a special interest in a simulations session during which the remote manipulator system (RMS, a mechanized arm) takes a momentary spotlight. They are seated at the CAPCOM or capsule communicator console in the mission operations control room of JSC?s mission control center. Dr. Ride will converse with astronauts Joe H. Engle and Richard H. Truly during their STS-2 mission in space when the RMS will have its debut in the Columbia?s cargo bay. Astronaut James F. Buchli, serving in a CAPCOM capacity, is partially obscured behind Dr. Ride. Photo credit: NASA
