December 7 marks the 50-year anniversary of the Blue Marble photograph. The crew of NASA’s Apollo 17 spacecraft – the last manned mission to the Moon – took a photograph of Earth and changed the way we visualised our planet forever.
Taken with a Hasselblad film camera, it was the first photograph taken of the whole round Earth and is believed to be the most reproduced image of all time. Up until this point, our view of ourselves had been disconnected and fragmented: there was no way to visualise the planet in its entirety.
