“Astronaut Alan B. Shepard, right, and Kenneth P. Timmons, Martin Marietta Aerospace executive, inspect the Skylab orbiting laboratory’s optical window at the Corporation’s Denver division. The window was meticulously hand-polished for weeks to attain an optical quality that will allow any cameras to scan the earth as if no window were present. It is located in the Skylab Multiple Docking Adapter which was assembled for NASA’s Marshall Space Flight Center, Huntsville, Ala. The docking adapter will serve as an experiment control center and space dock for arriving Skylab crewmen when the orbiting laboratory is put to use in 1973.”
