2008: Two USRA technicians laying on the floor of the mirror coating chamber at NASA Ames Research Center, Moffett Field, California, photographed themselves reflected in the perfectly coated SOFIA telescope main mirror suspended above them. Project engineers completed the first mirror coating of the German-built telescope in a 10-ton, 16-foot tall stainless steel vacuum chamber at Ames. It took just 20 seconds to apply the shiny aluminum coating to the glass mirror. (NASA/USRA Patrick Waddell)
