One of the Two Scientific Airlocks on the Orbital Workshop Section

This close up view of one of the two scientific airlocks on the Skylab Orbital Workshop Section was taken from the Skylab 2 Command/Service Module during its initial fly around inspection. The micrometeoroid shield can be seen to be missing from this section of the orbital workshop. A parasol solar shield was later devised and put in place over this damaged area through this very same airlock opening.
