Homonym: LEO (Lion)
LEO, or Low Earth Orbit, refers to the region of space that is approximately 160 to 2,000 kilometers above Earth's surface. This orbit is commonly used by satellites, including those for communication, weather monitoring, and Earth observation. Due to its proximity to Earth, LEO allows for lower latency in data transmission and easier access for satellite maintenance.
Many spacecraft, such as the International Space Station (ISS) and various Earth observation satellites, operate in LEO. This orbit is also a focus for future space exploration missions, including potential crewed missions to Mars and beyond, as it serves as a testing ground for technologies and systems needed for deeper space travel.
