5 Mind Blowing Facts About Spacewalks Space Station Nasa Astronomy
Objects in earth orbit have to travel at least 28 160 km h 17 500 mph.
Why are astronauts weightless in the space station. Why some people say no. The rocket pushes the station the station pushes on each and every thing interior such by using fact the astronauts. An object in a straight free fall or in a more complex inertial trajectory of free fall such as within a reduced gravity aircraftor inside a space station all experience weightlessness since they do not experience the mechanical forces that cause the sensation of weight. That s right they don t fall to earth but keep falling around it traveling at a minimum of 28 160 km h.
The answer to this is just a bit more complicated but the basis is that there is some gravity in space so the weightless condition of the astronauts doesn t have anything to do with gravity. As the bones weaken astronauts are more susceptible to breaking them if they slip and. Astronauts seem to float weightless in the iss and during spacewalks. Astronauts in space for weeks to months can run into trouble.
Earth 39 s gravitational field extends into space and therefore pulls the iss and astronauts inside it. We also have to remember that there are tons and tons of space debris as well as satellites that are out in space around the planet. Why some people say yes. Force fields other than gravity edit.
They experience weightlessness not because of a lack of gravity but because the iss and they are orbiting earth in constant free fall says valerie neal curator of space history at the national. It s actually the pull of gravity on a very very fast moving spacecraft that puts them into an endless fall making them experience the fun and sometimes nauseating thrill of weightlessness. Calcium in bones secretes out through urine. In fact the force of gravity does act on objects in the iss although they appear to float freely as.
Whilst the rocket is firing the astronauts do experience a push in any. Most astronauts never escape earths gravity. Is there gravity inside the international space station. The earth is curving away beneath them as they speed up towards it so they never succeed.
In reality the astronauts are actually falling and so is the space station.
