Technologies important to everyday life that were originally developed for astronomy are listed below (National Research Council, 2010):
•X-ray observatory technology is also used in current X-ray luggage belts in airports.
•In airports, a gas chromatograph — for separating and analysing compounds — designed for a Mars mission is used to survey baggage for drugs and explosives.
•The police use hand-held Chemical Oxygen Demand (COD) photometers — instruments developed by astronomers for measuring light intensity — to check that car windows are transparent, as determined by the law.
•A gamma-ray spectrometer originally used to analyse lunar soil is now used as a non-invasive way to probe structural weakening of historical buildings or to look behind fragile mosaics, such as in St. Mark’s Basilica in Venice.
