A launch window in LEO.
Low Earth orbit (abbreviated as LEO) is a kind of Earth orbit. In the game, an orbit around Earth that has an altitude between 30 and 120 kilometers is considered as a low Earth orbit. There are still some types of orbits around the Earth such as the middle Earth orbit (where some satellites orbit in) and high Earth orbit (where dead geostationary satellites lie).
This orbit is easily reachable, due to its low Delta-v requirements. It usually takes two rocket stages to reach LEO. See building orbital rockets for more information.
Usage[]
Low Earth orbit is the starting point for almost all missions. LEO can be used for the following purposes:
- Burn prograde to execute the Hohmann transfer to a higher orbit
- Await for an interplanetary transfer window
- Holding an Earth space station
- Communications satellites
- Achieving a heliocentric orbit
- Parking orbit
- Orbits of satellites
