THE MATERIAL THAT ALLOWED SKYLAB TO BE A FLIGHT SUCCESS.
Skylab Sunshade Material. Two samples, each approximately ½ by 1 inch, showing the front and back of the material used during the Skylab space station rescue operations. Both are mounted onto an 11 by 8 inch display certificate which has images of the sunshade assembly and after it was deployed in space to protect Skylab. Sample number 727 of 2500.
The certificate reads: "The attached are samples of Skylab sunshade material. It was constructed from ½ mil Mylar, the Du Pont trademark name for polyester film. The Mylar was aluminizied and then bonded to 1.1 ounce weight nylon ripstop. During the unmanned launch of the Skylab space station (SL-1 mission) on May 14, 1973, a shield designed to protect Skylab from micro-meteoroids and temperature extremes was torn off due to aerodynamic forces. The temperatures inside Skylab soon soared to well over 100 degrees F.
Ground support crews devised a method of erecting a parasol sunshade. It was deployed by the first manned flight called Skylab I (SL-2 mission) insuring a successful 28 day flight. The Skylab II crew (SL-3 mission) later installed a larger and improved sunshade during a 59 day flight. The sunshade material enabled all three manned missions to take place, allowing a successful completion of the Skylab program."
