Satellites have become our planet’s orbiting guardians, silently circling Earth and gathering data that help scientists unravel the story of climate change. Using advanced sensors, these high-tech observers measure everything from global temperatures and greenhouse gas levels to shrinking ice sheets and disappearing forests. The result is a revolution in climate monitoring – a wealth…

Definition and How Geostationary Orbit Works A geostationary orbit (GEO) is a circular orbit around Earth’s equator at approximately 35,786 km altitude (about 22,236 miles) where a satellite orbits once per sidereal day (~23 hours 56 minutes) in the same direction as Earth’s rotation en.wikipedia.org esa.int. This precise altitude and orbital period make the satellite…

Introduction: LEO and the Rise of Small Satellites Low Earth Orbit (LEO) generally refers to orbits up to about 2,000 km above Earth’s surface nasa.gov. At these altitudes, satellites circle the globe in ~90–120 minutes, close enough for low-latency communications and high-resolution observations. In recent years, small satellites – typically massing from a few kilograms…

Imagine sending a text from the middle of the ocean or deep in the mountains with no cell tower in sight. That’s the promise of Starlink’s new Direct-to-Cell technology – a “cell tower in space” that lets ordinary phones connect via satellite when terrestrial coverage is absent. In recent trials, SpaceX’s Starlink satellites have successfully…
