Space weather refers to variations in the space environment between the Sun and Earth that can affect technological systems both in orbit and on the ground swpc.noaa.gov. It is generated by solar phenomena—particularly solar flares, coronal mass ejections (CMEs), high-speed solar wind streams, and solar energetic particle events—that release bursts of radiation and charged particles…

Imagine a satellite that not only takes pictures of Earth, but can also identify what materials compose each pixel of the image. This is the promise of hyperspectral imaging – a technology giving satellites “super-vision” across hundreds of colors beyond human sight. Hyperspectral sensors capture detailed spectral fingerprints of objects by measuring reflected light in…

Starlink, SpaceX’s satellite internet network, has rapidly expanded coverage worldwide since its beta launch in 2020. As of mid-2025, Starlink service is available in over 110 countries and territories, with more on the way idemest.com. Below is an up-to-date regional breakdown of Starlink availability – including countries with full commercial service, those in beta or…

Definition and Basic Principles Satellite imagery refers to images of Earth (or other planets) collected by orbiting satellites. These images are a form of remote sensing, meaning the data are acquired from a distance without direct contact. Satellites carry sensors that detect electromagnetic radiation reflected or emitted from the Earth’s surface. Most imaging satellites use passive sensors that rely…

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…

Chad, a vast landlocked nation in Central Africa, has one of the world’s lowest rates of internet connectivity. As of early 2025, only about 13% of Chadians use the internet, compared to a global average around 60% capmad.com. This places Chad near the bottom globally in internet access. The digital infrastructure is underdeveloped, and most…

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…
