Abstract
Many people mistakenly think that gravity doesn’t exist in space. However, typical orbital altitudes for astronauts vary between 200 and 550 km above Earth’s surface and the gravitational field is still quite strong at these altitudes. In fact, Earth’s gravitational field at about 400 km above the surface is 88.8% of its strength at the surface - it’s the reason why the International Space Station (ISS) is kept in orbit around Earth.
