Three rovers, six US flags, dozens of probes that either landed successfully or crashed, tools, cameras and trash: the Moon is dotted with hundreds of objects as a result of space exploration.
Some experts are calling to grant them heritage status to protect them from future tourists and human activity.
It all started on September 13, 1959 when Soviet probe Luna 2 smashed into Mare Imbrium, its 390 kilograms (859 pounds) of mass vaporizing, no doubt, on impact.
It was followed in succession by more Luna probes, then it was the Americans’ turn with the Ranger and Surveyor programs.
And then, on July 20, 1969, the first humans, Neil Armstrong and Buzz Aldrin.
The pair spent 22 hours on the Sea of Tranquility. They left behind everything that wasn’t necessary to taken back: the lunar module’s descent stage, cameras, lunar boots, tongs, commemorative objects, and four “defecation collection devices.”
Five more successful Apollo missions left behind hundreds of additional objects.
