NASA has revealed the moon has various pieces of junk littering its surface, including a US flag, a urine-collection device, a golden olive branch, a falcon feather and a hammer.
The feather and hammer were famously used to show the objects would fall at the same rate.
These items are on top of the dozens of other pieces of equipment – such as moon rangers – left on the giant space satellite.
It is estimated that the weight of all the debris is more than 181,000kg if it was calculated on Earth.
“On any engineering project, like landing on the moon, you design the mission to do what you need”
William Barry, NASA chief historian
Most of the rubbish was left behind by astronauts on the various Apollo missions between 1969 and 1972.
Other bits are from lunar probes sent up there to explore.
NASA chief historian, William Barry, said the reason for all the moon junk is that astronauts would’ve used precious resources, like fuel, bringing it back to Earth.
He explained: ”On any engineering project, like landing on the moon, you design the mission to do what you need it to do and not a whole lot more.
“The real concern was: Can we get the crew safely to the moon, can they get the samples they need and can we get them back in one piece?”
Last month it was claimed NASA faked its Apollo 15 landing.
A video of the mission was posted online that apparently shows noise being made by astronauts – something that is impossible in space as there is no air.
