How High Is the Iss?

The International Space Station is a modular space station in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA, Roscosmos, JAXA, ESA, and CSA. The ownership and use of the space station is established by intergovernmental treaties and agreements.

How far above the earth is the ISS?

How far away is the ISS? The space station orbits Earth at an average altitude of 227 nautical miles/420 kilometers above Earth.

How long does it take to reach the ISS?

It can take anywhere from 6 hours to 3 days to get to the International Space Station, depending on the spacecraft and mission profile. It took the Apollo astronauts about three days to get to the Moon. Although the Moon is much farther away than the ISS, the Apollo spacecraft travelled more directly and quickly.
