- Low Earth Orbit (LEO)
#nizka-obezna-draha-leo#bodies
Low Earth orbit, commonly called LEO, is the most accessible region of space. It is where the first orbital flights, spacecraft rendezvous, spacewalks, and long-duration station crews were demonstrated.
LEO is not a single altitude or a single orbit. The choice of a particular orbit depends on inclination, altitude, launch-vehicle capability, atmospheric drag, and mission purpose. For human spaceflight it is essential infrastructure for further expeditions.
Key context
- Atmospheric drag in LEO gradually lowers the orbit of objects without periodic corrections.
- The ISS operates in low Earth orbit.
- Reaching LEO primarily requires gaining high horizontal velocity.
