Did you know that a suit for an astronaut costs $ 12 million?

Another interesting astronauts related issue is that, while in outer space, they can’t cry because there is no gravity, so the tears don’t fall down their face. Most astronauts grow by 2 cm in space, their heart becomes rounder, and they stop snoring.

Sleeping for them is a great adventure due to a lack of gravity, so most of them are fond of sleeping in a specially designed sleeping bags that are attached to the wall or floor.

What is not so pleasant is the fact that almost every one of them feel the consequences of some space sickness, caused by a broad spectrum of confusing information coming to their inner ear.
