I hope that was facetious, but anyway, I feel I should remind people that space at the distance the Columbia is flying is a much better vacuum than that of a Thermos bottle. Other than in esoteric measures (the temperature of the background radiation, or the "temperature" of the solar wind), space can be thought of as not having any temperature. The only way you can lose (or gain) heat in space is through radiative transfer. Does anyone have any data on to what extent the Columbia's coloring is due to the intended effects on its albedo, how much is has to do with other desired properties of the materials, and how much is due to esthetics?
