If you noticed an unusual glow in the sky last Wednesday, it wasn’t a shooting star — it was astronauts’ urine.
The glow was the result of the space shuttle Discovery releasing an unusually large amount of water and urine into outer space.
Unusually large as in 150 lbs., according to Space.com.
Why did Discovery drop its waste payload? According to a NASA spokeswoman in the article, it’s the result of recent restrictions on waste disposal while the space shuttle is docked with the International Space Station.
Which leaves one simple question: what happens when you release pee in space?
Liquids released into space apparently freeze as tiny ice shards first. Once the sun’s rays strike, the ice sublimates into vapor and disperses into space.
