You Need to Drink 730 Liters of Recycled Sweat and Urine to Live in Space for a Year
Water is like liquid gold in space, so in order to live up there for a year astronauts have to resort to drinking their own waste. That means drinking up to 730 liters of their own sweat and urine.
Chunks of Our Galaxy Are Being Sucked Away by Something Bigger Than Anything in the Known Universe
Bad news: there's something out there, beyond the known universe, larger than anything in the known universe, and it's sucking our galaxy away from us. Scientists who think they're hilarious call this concept "Dark Flow." A better name for it is "NASA's Instant Nightmare Juice."
Being In Space Can Literally Change Your DNA
If you're an astronaut and spend an extended time in space, it will literally change your genetic makeup. We know this thanks to astronaut Scott Kelly, who spent a year at the International Space Station. Back on Earth was his identical twin brother Mark - also an astronaut. Upon Scott Kelly's arrival, scientists compared the two's DNA and found he changed in some horrifying ways. He got taller, the bacteria inside his gut was completely different, and his genes had changed.
Scientists believe his year at the ISS caused "space genes" to alter nearly everything about his body. As it turns out, this seems irreversible, meaning Scott and Mark are no longer identical twins.
You Can Drown Inside a Spacesuit
Here's how it happened: a routine spacewalk almost turned disastrous for one astronaut outside of the ISS back in 2013. His spacesuit began to mysteriously fill with water due to leak (water is used in the suits for cooling as well as drinking). His helmet would have filled with water and drowned him while in outer space if it wasn't for the brave efforts of his fellow astronauts to save him.
