A photo from open sources Science has long known that during space flight astronaut grows by as much as two inches (a little more than five centimeters). The explanation is very simple: being behind outside the home planet, in zero gravity, people almost do not experiences the force of gravity of the Earth, due to which the spine astronaut lengthens.
This fact must be taken into account when planning the space ship and making spacesuits for crew members.
After returning to his home planet, the astronaut another ten days will be a few centimeters higher. During this time, his vertebrae have time to return to familiarity with Earth’s gravity state.
A similar phenomenon of spinal extension The weakening of gravity happens to us earthlings every day – waking up in the mornings, we don’t even guess what time of night grow half an inch. True, this phenomenon is also short-lived – very soon we will return to our normal growth.
NASA scientists familiar with how gravity affects human growth, convinced that if in the future we succeed colonize Mars, then people born on the Red Planet will much higher than earthlings. Gravity on Mars is almost three times less than on our planet, and if ever a Martian visits The earth will be surprised what dwarfs inhabit it.
There have always been many questions about space, for example, are sex astronauts? What will the astronauts themselves say about this?
