Astro poop
It’s my strong opinion that all Apollo landing sites should be left alone and treated as protected areas. That said, there are some items of scientific value that should be retrieved, including the human waste bags left behind by the astronauts. These bags, containing urine and poop, contain biological materials that scientists would very much like to study. Any microbes, such as bacteria, that once lived in these waste products are probably long dead, but biologists would like to prove that for certain, as it speaks to the potential for interplanetary microbial contamination.
