An idea is born. Check out this awesome sketch of Skylab, drawn by Dr. George E. Mueller, former NASA associate administrator for Manned Space Flight. Mueller drew the sketch on August 19, 1966, during meeting at NASA's Marshall Space Flight Center in Huntsville, Ala. He used a felt pen and poster paper to pin down the final conceptual layout for the budding space station's (named Skylab in 1970) major elements.
