DownloadIn July of 1969, Neil Armstrong and Buzz Aldrin left the first human footprints on the moon.
They also left two pairs of boots, a handful of tools, and four vomit bags.
This lunar litter was far from the last space junk humanity has produced.
In 2006, Suni Williams lost her camera while tussling with a stuck solar array on the ISS.
And the following year, a similar job resulted in the loss of a bag filled with $100,000 worth of tools.
These accidental satellites typically have short lifespans, before falling back to Earth and burning up in our atmosphere.
However, other pieces of space junk, like SpaceX’s Tesla Roadster, will be stuck in their orbits for the foreseeable future.
