The Apollo missions were the United States' series of manned space flights that landed NASA astronauts on the moon in 1969. All together, there were 17 Apollo missions between 1961 and 1972.
Of course, thousands of photographs were taken by the astronauts and by NASA. And now, thanks to the Project Apollo Archive, about 13,000 high-resolution scans of those photographs are available for anyone to look through online.
Because of budget cuts at NASA, the archival photos were handed over to Project Apollo Archive founder Kipp Teague. He's been uploading them to Flickr, and hopes to have all of them online by the end of the week.
The photos include the astronauts, shots of the moon and of Earth and, of course, the moonwalks. You could spend hours perusing these amazing historic photos taken in space.
