The Apollo missions have left 96 bags of poop, pee, and vomit on the moon. Back in 1969, mankind made history by walking on the moon for the first time. That wasn’t the only first that happened on that momentous trip – it was also the first time literal trash was dumped on the moon. Subsequent voyages to the moon followed suit, leaving behind all their unwanted trash, but it turns out that’s all for a good reason – the returning spacecraft don’t have enough fuel to carry all that weight back!
