When you poop in space, everyone screams.

Here are some fascinating, colorful photos of food items in space, from the early days of space travel to today.

Twice a day, I pour my dog a bowl full of kibble, a specially formulated blend of barley, lamb, herring, and few other goodies I'm told will fully meet his nutritional needs.

In the US and Russian space programs, many rituals are attached to missions, perhaps to add a little good fortune to their science.

Astronauts may not expose their nostrils to the vacuum of space, but folks who come back from space walks report that they've brought a very distinctive odor back with them. And the space stations have their own special (and not necessarily pleasant) scents, including perfume of the Mir Space Station, which is…

The astronauts in Nathan Hoste's Bodies in Space illustrations left the airlock without proper attire, and they're suffering the consequences. Without the benefit of airtight spacesuits, their bodies are experiencing sunburns, bruising, and worse.

You've probably heard of necrotizing fasciitis, also known as flesh-eating bacteria. But bacteria do not actually eat human flesh. They're actually trying to gobble up something a lot weirder.
