Pencil on paper drawing of Comet Kohoutek made by astronaut E. G. Gibson during the Skylab 3 mission. Gibson, the science specialist and pilot for the third manned Skylab visit, is a solar physicist and focused on the astronomical experiments. He took the opportunity to observe the comet visually through different windows in Skylab during the 84-day mission, supplementing electronographic images taken by various Skylab telescopes.
The full suite of over a dozen drawings and renderings was split between the space science collection and the art collection after it was donated by the Aerospace Corporation. This drawing, labeled "day 363" represents the comet one day after perihelion as it developed a sunward spike.
