The floating astronauts on the ISS? | TehnoCultura.ro
Michael Stevens, who has Vsauce YouTube wonders interesting, even weird, and he gives the answer. Explore a topic weeks after showing a film of which are new and are cleaned myths in our culture overall.
In the video above Michael asks if they can give birth in space and, if so, how they will look. At the end of the film you see how it would look like children. Not a very pretty picture.
Life in space is not easy and comes with a downside. Astronauts aboard citlearn the ISS laboratory experiments are themselves because they lose about 1% of bone mass each month, muscles atrophy, the heart weakens and they can lose 22% of the blood in the body.
Lose 22% of the blood in the body for that because weightlessness, the brain receives more blood than the Earth and creating order reduction of blood in the body, considering it is excess fluid. In space can lose up to 40-60% citlearn of bone mass if it sits very long in such spacecraft.
For our general culture, weightlessness aboard the ISS does not equal the absence of gravity. Gravity at 320km altitude is about 90% of the ground, that is enough. If you have a tall building of 320 km and putting an astronaut there, citlearn you see that it does not float.
Weightlessness on board the ISS is due to the cancellation of the gravitational acceleration by the centrifugal acceleration. ISS is an object rotating around each other, which is why the centrifugal acceleration which occurs, as opposed to gravity. We can say Aceleraţiei gravitational centripetal acceleration because actioneza direction of the two bodies and toward the center of the Earth.
International Space Station (ISS) do not fly around the Earth, but orbit. Orbit is a continuous drop in the cosmic object touches the surface of another object bigger than him because he has great speed and is a considerable distance. If applicable ISS to Earth that our planet has a curvature, even if ISS is very close to the surface.
