The Pioneer and Voyager messages were high-minded attempts to communicate with other civilisations, to let them know we are here. Postcards for aliens, if you like. But Paglen says that the Last Pictures project is very different. “[The Voyager team] were very sincere about how to explain life on Earth to extra-terrestrials. This is not like that at all, we’re not going to the final frontier or anything like that.” In fact he does not imagine that his work will find an audience. “I don’t think it will ever be found,” he says.
