   Oct 12, 2024 · News •. low Earth orbit (LEO), region of space where satellites orbit closest to Earth ’s surface. There is no official definition of this region, but it is usually considered to be between 160 and 1,600 km (about 100 and 1,000 miles) above Earth. Satellites do not orbit below 160 km because they are affected by atmospheric drag.

   A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. [ 1 ] Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around 800 km (500 mi), [ 2 ] while the farthest in LEO, before medium Earth orbit (MEO ...

   May 30, 2022 · In very simple terms, low Earth orbit (LEO) is exactly what it sounds like: An orbit around the Earth with an altitude that lies towards the lower end of the range of possible orbits. This is around 1,200 miles (2,000 kilometers) or less. The majority of satellites are to be found in LEO, as is the International Space Station (ISS).

   What happens if a spacecraft goes into low Earth orbit?

   • When a spacecraft goes into low Earth orbit, it won’t stay there forever. As objects orbit the Earth, they interact with the atmosphere. There is a small air drag force similar to the forces a on a bullet shot from a gun—well the big difference is the size of the drag force. In LEO, the air is really thin and exerts just a tiny force on objects.

   Is the ISS in a low Earth orbit?

   • The ISS is in a low Earth orbit. Credit: NASA Despite this, most objects in low Earth orbit are in the first 100-200 miles of space, so some NASA sources simply consider LEO to be the space occupied by LEO orbits. Yes, the reasoning is a bit circular, but we are talking about orbits here.

   What is a low Earth orbit?

   • Orbits of satellites that reach altitudes below 300 km (190 mi) decay fast due to atmospheric drag. Objects in LEO orbit Earth between the denser part of the atmosphere and below the inner Van Allen radiation belt. Equatorial low Earth orbits (ELEO) are a subset of LEO.

   Is low Earth orbit very high?

   • Low Earth orbit is not very high. Yes, we think about LEO as being way up there in space—and it is indeed very high. The International Space Station orbits 400 km above the Earth’s surface. However, in terms of orbits, that’s not that far. Take a look at this python model (using trinket.io) that shows the path of the ISS around the Earth.

   Why is low Earth orbit important?

   • Low Earth orbit provides an ideal environment for crew training, research, and hardware testing for exploration use. NASA will need access to a human-rated destination in LEO following the life of the International Space Station, and the agency intends to be a significant customer of space services.

   The U.S. Space Transportation System, STS, or Space Shuttle, was designed as a reuseable system to reach Low Earth Orbit. Most of its components were refurbished and reused multiple times. Upper Stage Rockets can be selected for placement atop the launch vehicle's lower stages (or within the Shuttle's cargo bay) to provide the performance needed for a particular payload.
