Actual poop. Human dung. From the Guardian article linked to above:Are you talking about actual poop or trash?
Because the moon is considered lifeless, Nasa’s office of planetary protection does not frown on missions that spill Earthly organisms on its surface. After all, the Apollo astronauts left behind their own microbes in the 96 bags of human waste that await some future cleaner on the moon. Had the spacecraft spilled its living cargo on Mars, the story might be very different.
I never knew this until today! When was the first time you ever thought of 96 bags of human poop laying on the moon? Nice thought, no? Welcome to club.
