Artist's concept of Skylab 4 astronauts observing Comet Kohoutek

S73-37274 (1973) --- An artist's concept illustrating how the Skylab 4 astronauts will observe, through the scientific airlock of the Orbital Workshop, the passing of the newly-discovered Comet Kohoutek. The favorable location of the Skylab space station in Earth orbit will help provide a comprehensive investigation of the nature and evolution of the coma and tails as the comet approaches, passes, and recedes from the sun.
