WebAn example of this is the International Space Station (ISS), which has an operational altitude above Earth's surface of between 330 and 410 km. Due to atmospheric drag the space station is constantly losing orbital energy. In order to compensate for this loss, which would eventually lead to a re-entry of the station, it has from time to time ... WebSep 16, 2024 · The speed of ISS is the same as the first orbital velocity, which is 7.9 km/s. For a better demonstration of its moving speed, the French astronaut Thomas Pesquet, …

WebThe International Space Station is on average orbiting at an altitude of around 230 miles (370 km), but is currently roughly at an altitude of 260 miles (418 km) as it just completed an orbital reboost a few days ago (or maybe it was yesterday, my biorhythm is all messed up). WebThe ISS orbits the Earth in a ~circular orbit at an altitude of 353 km. The Earth's radius is 6378 km, giving the ISS a semi-major axis of 6731km, or 6731000 meters, and an eccentricity of 0. Circular orbital velocity for this orbit would be: where: G is the gravitational constant, M is the mass of the Earth, r is the semi-major axis of the ISS, WebCalculated for a circular orbit of 200 km (120 mi) the orbital velocity is 7.79 km/s (4.84 mi/s), but for a higher 1,500 km (930 mi) orbit the velocity is reduced to 7.12 km/s (4.42 mi/s).
