Even though free fall causes objects on the International Space Station to appear to be weightless, there actually is gravity. Gravity gets weaker as you move away from the Earth, although it still exists. The change in gravity can be calculated with the equation: 1/(Radius^2). The Earth is about 4000 miles in radius, so in the equation, 4000 miles would be R=1. At 4000 miles in altitude, the distance to the center of the Earth would be 8000 miles so it would use R=2 (twice the radius of the Earth). At the space station's altitude of 200 miles, the equation would use R=1.05. 1/(1.05^2) equals about .91, so gravity on the space station is about 91% of the gravity on the Earth.
By spinning, the centripetal force creates artificial gravity on the space station.
The force of gravity keeps the space station in orbit as well as inertia that keeps the space station moving in a straight line.
I'm not sure if it's ever measured, but it could be approximated by calculating the surface gravity of a spherical asteroid of equal mass and dimensions.Assuming the mass of the International Space Station is 450 000 kg (M) and its mean radius is about 30 meters (r) , the surface gravity would be g = MG/r2 = about 0,00000003337 m/s2 (about 30 nanometers/square second).For comparison, Earth's surface gravity is about 9.81 m/s2, so the gravity you would experience standing on the surface of the International Space Station is about 0.3 millionth of a percent compared to earth. It's certainly too small a gravity to hold you attached to the station if you were standing on it.If you're inside the space station, in the center of the station, there is zero gravity because you are in the center of gravity because the mass of the station is situated around you.Panu, M.Sc.
If he is aboard something that's in Earth-orbit, like the International Space Station or the Space Shuttle, then Earth's gravity is what's keeping him in orbit.
Yes, there is gravity on the International Space Station (ISS), but it is not due to the station being in Earth's orbit. The sensation of weightlessness experienced by astronauts aboard the ISS is because they are in a state of constant free fall towards Earth, creating the effect of microgravity.

The International space station is constantly falling towards Earth under the pull of Earth's gravity (Just like any other object - gravity does not stop when you reach space!). However the Station is moving very fast horizontally and, as the Earth is a sphere, this means that as it falls its path takes it round the Earth in a circle - it is in "orbit". This means that if you are in the space station you are falling as fast as gravity can pull you and therefore you do not feel the pull of gravity, making you weightless.
no.
the distance
Compared to a planet a space station is tiny. While all objects with mass gave gravity, that of a space station is negligible, and certainly could not keep a moon in orbit.

As of 2010, artificial gravity technology has not been invented.
