English: Scientist-astronaut Edward G. Gibson, Skylab 4 science pilot, stands at the Apollo Telescope Mount (ATM) console in the Multiple Docking Adapter (MDA) of the Skylab space station cluster in Earth orbit. This picture was taken with a hand-held 35mm Nikon camera. The ATM console was one of the busiest areas of the space station during the 84-day third manned Skylab mission, as Comet Kohoutek and solar activity were closely followed by the ATM and monitored by the crewmen from the ATM console. As Gibson demonstrated during a television transmission on Dec. 5, 1973, the ATM console controls several instruments on the solar telescope. Joining Gibson for the record-setting Skylab 4 mission were astronauts Gerald P. Carr, commander, and William R. Pogue, pilot. Photo credit: NASA
