Why can't astronauts burp in space?

On Earth, gravity pulls liquids and solids to down to the bottom of our digestive systems, while gases stay up top and get forced back up the esophagus as a burp. That can't happen in space.

How do they sleep in space?

A crew member sleeps in a sleeping bag located in a crew cabin. As a result, astronauts are weightless and can sleep in any orientation.

How do astronauts brush their teeth?

First, the astronaut attaches their toothpaste tube to a nearby wall. Then, the astronaut takes their toothpaste and repeats the same process. They will brush their teeth like usual!

Because the space shuttle doesn't have a refrigerator, foods must stay fresh at ambient temperatures.

Do things rot in space?

If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.

Why are there no refrigerators in space?

As the temperature in space is well below freezing -100C or so, there really is no need for a fridge. All an astronaut need do is place milk and other perishables in a carrier bag, (even frozen food) and simply hang it out of the window. There are refrigerators on the ISS.
