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!

After weeks of mailing out this year’s holiday cards, postage might be the last thing you want to think about. But the U.S. Postal Service has just given us a sneak peek at the many iconic people, places, and things that will be commemorated with their own stamps in 2018, and one in particular has us excited to send out a few birthday cards: Mister Rogers.

In celebration of the 50th anniversary of Mister Rogers’ Neighborhood, Fred Rogers’s groundbreaking PBS series that the USPS says “inspired and educated young viewers with warmth, sensitivity, and honesty,” the mail service shared a mockup of what the final stamp may look like. On it, Rogers—decked out in one of his trademark colorful cardigans (all of which were hand-knitted by his mom, by the way)—smiles for the camera alongside King Friday XIII, ruler of the Neighborhood of Make-Believe.

Though no official release date for Fred’s forever stamp has been given, Mister Rogers is just one of many legendary figures whose visages will grace a piece of postage in 2018. Singer/activist Lena Horne will be the 41st figure to appear as part of the USPS’s Black Heritage series, while former Beatle John Lennon will be the face of the newest Music Icons collection. Sally Ride, the first American woman in space, will also be honored.
