Astronauts' personal photographs with hand-held cameras during the early space missions gave Earth's inhabitants a new view of their home: a fragile and subtly-coloured globe, suspended in a black void. Now, several dozen satellites stream back images which routinely illustrate weather-forecasts and environmental news-stories. Once available only to the military, these are routinely made available by agencies such as NASA, and high-resolution imagery (at scales comparable to aerial photographs) is widely available commercially. These images allow a "zoom" from a global to a local view, giving a better appreciation of the settings of ancient sites both within their immediate landscapes and in the context of corridors of communication with a wider world.
