A great graphic from Michael Paukner on Flickr of all the world’s satellites, working and defunct, plus debris, by country. Interestingly, China and France appear to the worst litterers of space as a proportion of the amount of stuff they have up there. Russia have the most out of commission satellites and the USA (not surprisingly) have the most working devices. Of course, this graphic doesn’t distinguish civil from military, nor say what are their functions, but the sheer amount of stuff in orbit indicates why there will be serious conflict over the use of orbital space soon enough…
