It’s one of the most replayed moments in the history of the world, but even the moon landing has its unseen moments.

After 45 years in the NASA archives, TIME has uncovered stunning behind the scenes images of the Apollo 11 crew during their incredible mission.

Apollo 11 astronauts Neil Armstong, Buzz Aldrin and Michael Collins took a whole heap of photos while being the first men to land on the moon, but not all were for public consumption.

Along with telling the stories of some of the more ubiquitous photos from the landing, TIME explored NASA’s catalogue of images for the more intimate moments the crew shared.

Amongst the shots, we learn just how cramped and claustrophobic the lunar landing module was.

We also see a photo of Armstrong just after he’s completed the moonwalk, sporting a wide smile from ear to ear.

The second man on the moon

No one remembers who came second? Armstrong did. Here he snaps Aldrin as he’s about to be the second man on the moon. Photo: NASA
