Submission + - The Mystery of the 'Only Camera to Come Back from the Moon' (vice.com)
But contrary to claims repeated across the Internet on Monday, this isn't the only camera to come back from the moon. In fact, some think it may have never landed on the moon at all. And because of rules surrounding most NASA property, its sale may actually violate US law.
One thing we know for sure, maybe: the 70mm Hasselblad 500 is one of fourteen cutting-edge cameras that astronauts used in orbit around the moon and on the lunar surface during the Apollo program. All of the images we have from those moon missions were taken by these machines, which were either mounted inside the command module that circled the moon or were attached to space suits at the chest.
This particular camera was, reports the Verge, among many other sources, "used on the moon during the Apollo 15 mission in 1971," and "is special in the fact that it's returned to Earth." That's because astronauts were often instructed to jettison their cameras on the lunar surface in order to save precious kilograms during the return trip.
