Here is a partial list
of the trash that humans have left on the moon:
more than 70 spacecraft including rovers, modules, and crashed orbiters,
12 pairs of boots,
2 golf balls,
an assortment of empty
packages of space food,
various hammers, tongs, rakes, and
backpacks, insulating blankets,
utility towels, used wet-wipes,
discarded 'personal hygiene kits'
and 96 bags containing the piss, shit, and vomit of departed astronauts.
Humans have left, all told, nearly 400,000 pounds
(= nearly 200,000 kg) of stuff on the surface of the moon;
Buzz Aldrin and Neil Armstrong alone left more than 100 items on the Sea of Tranquillity
— including a plaque claiming that "we came in peace for all mankind."
And soon, of course, more mendacious and meretricious advertising
will be placed on the helpless, battered satellite —
a chemical drink will start off the commercial blight.
