To unbelief, the moon was littered by people with about 500,000 pounds of "garbage," according to NASA reports.
Some parts of this "garbage" include a golden olive branch, flag gear, lunar orb, a hammer, and a falcon's feather, reports Live Science.

Much of the litter was left by NASA astronauts who landed on the Moon during the Apollo missions between 1969 and 1972. Other types of garbage are from unmanned space exploration missions from the United States, Japan, Russia, India and Europe, said William Barry, a NASA chief historian, on Live Science.

The significant weight of lunar litter is one of serious artifacts, such as "five moon rangers and moon probes that are still there," Barry told Live Science.
The reason these objects were left behind on the moon was simple, because "little thought was given to bringing back unimportant equipment."
"The real concern was, can we bring the crew safely to the moon, can they? get the samples they need, and can we get them back in one piece? "Barry told Live Science."
But lunar waste has actually given NASA researchers another research field, such as how the materials survive the radiation conditions and the vacuum of space over time, Barry told Live Science Moon is still used – like the laser range reflector left there by the Apollo 11 crew.
NASA published a complete list of objects remaining on the Moon, although there is probably more since the list since 2012 was not updated, according to Live Science.
