6 Facts About Food In Space

Despite what you've heard, there's more to eating in space than freeze-dried ice cream and Tang. Find out which foods work while in orbit and which are better left on Earth with these facts. Neil deGrasse Tyson and the StarTalk team answer even more of your questions about space travel in "StarTalk" from National Geographic Books: http://smarturl.it/StarTalkFoodPB

  1. 1

    Food tastes and smells bland in orbit.

    In dry environments with low atmospheric pressure —like space stations—human taste buds and noses don't work that well.

  2. 2

    You need to change the consistency of spices.

    If you start shaking a salt-and-pepper shaker, it all goes into the air around you. As a result, spices are made into liquids for space flight.

  3. 3

    You can't bring a pulled pork sandwich with you.

    Even when fully cooked, many foods, especially meats, contain microorganisms that are harmless on Earth but are unwelcome and even dangerous in spacecraft environments.

  4. 4

    Pizzerias on Venus would have quick turnaround time.

    According to Neil deGrasse Tyson, a 16-inch pizza would cook in nine seconds on a windowsill.

  5. 5

    Tortillas are the bread of choice.

    Unlike most kinds of bread, tortillas make minimal crumbs, making it easier to clean up your space sandwich.

  6. 6

    Meat sources would be different on Mars.

    Sheep, pigs, and cows are large, messy, and difficult to care for – let alone transport to another planet! Chickens and ducks are also messy because of their feathers and seafood wouldn't survive without a reliable water source. What does that leave? Mouse stew.
