Mega-Constellation
An extremely large network of hundreds or even thousands of satellites orbiting Earth, designed to provide widespread services like global internet.

TECHNICAL DEFINITION
A Mega-Constellation is an exceptionally large network of hundreds to tens of thousands of satellites, primarily in Low Earth Orbit (LEO), deployed by entities like Starlink or OneWeb to provide global, high-bandwidth services such as broadband internet, posing challenges for space traffic management and orbital debris.
BACKGROUND
Space sustainability aims to maintain the safety and health of the space environment, as well as planetary environments. Similar to sustainability initiatives on Earth, space sustainability seeks to use the environment of space to meet the current needs of society without compromising the needs of future generations. It usually focuses on space closest to Earth, Low Earth Orbit (LEO), since this environment is the one most used and therefore most relevant to humans. It also considers Geostationary Equatorial Orbit (GEO) as this orbit is another popular choice for Earth-orbiting mission designs.

USAGE NOTE
The deployment of mega-constellations raises concerns about orbital debris and light pollution.
