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.

Its surface tension hold it in a logical shape (why is a bubble spherical?)

Spaceships are limited in crew because of weight and consumables (mainly oxygen). But more people can travel in them as their design and technology improves. - The earliest manned missions carried only one, and later two, and three for the Apollo missions to the Moon. - The first Soviet space station, Mir, could hold about 7 or 8 for a short period, but normally 3 or 4 at most. - The Space Shuttle carried from 3 to 7 crew members, and could transport as many as 10 without modification. - The International Space Station has an upper capacity of 14 astronauts for a day or so, with the standard resident crew being 6 (since 2009). - Some of the planned manned missions to Mars could carry a crew of 3 to 5.

A man holds the record for the longest continuous time spent in space. Russian cosmonaut Valeri Polyakov spent 437 days aboard the Mir space station in 1994-1995.
