Low Earth Orbit (LEO) is a region of space that extends from about 100 to 2,000 kilometers above the Earth's surface. It is the most commonly used orbit for satellites, including those for communication, weather monitoring, and scientific research. Notable missions, such as those involving the International Space Station, operate within this altitude range, allowing for easier access and shorter travel times. Satellites in LEO experience less latency and can provide high-resolution images of the Earth. This makes LEO ideal for applications like Earth observation and remote sensing. However, satellites in this orbit must contend with atmospheric drag, which can affect their operational lifespan.
