Where Does Astronaut Poop End Up?

The next time you see a shooting star, just know: It could be astronaut poop. 

NASA released the infographic above to highlight some of the changes astronaut Scott Kelly’s body will go through during his year aboard the International Space Station with Russian cosmonaut Mikhail Kornienko. The mission, designed to study the effects of long-term spaceflight, is about twice as long as the average ISS trip, and the space explorers are about halfway through their journey. 

Along with factoids such as how much Kelly will exercise and how much radiation he’ll be exposed to, NASA shared several numbers that will interest the toilet enthusiasts among us. Kelly will drink 730 liters of water drawn from recycled urine and sweat, and he’ll produce 180 pounds of feces (barring any unforeseen incidents). Astronaut poop can’t just be flushed down the drain, of course, because space has no sewer pipes. Instead, it’ll be cast off from the station along with other ISS trash. It will eventually incinerate due to the extreme heat of atmospheric re-entry, sort of like a meteor

And, just like a meteor, that hot ball of poop trash will light up across the sky like a shooting star. But, as NASA cautions, “your feces will not be shooting stars.” Killing our dreams, NASA!

Tracing a word’s origin and evolution can yield fascinating historical insights—and the weird nicknames used in some states to describe their residents are no exception. In the Mental Floss video above, host John Green explains the probable etymologies of 29 monikers that describe inhabitants of certain states across the country.

Some of these nicknames, like “Hoosiers” and “Arkies” (which denote residents of Indiana and Arkansas, respectively) may have slightly offensive connotations, while others—including "Buckeyes," "Jayhawks," "Butternuts," and "Tar Heels"—evoke the military histories of Ohio, Kansas, Tennessee, and North Carolina. And a few, like “Muskrats” and “Sourdoughs,” are even inspired by early foods eaten in Delaware and Alaska. ("Goober-grabber" sounds goofier, but it at least refers to peanuts, which are a common crop in Georgia, as well as North Carolina and Arkansas.)

Learn more fascinating facts about states' nicknames for their residents by watching the video above.
