The Sun is our life-giving star – a 4.6-billion-year-old solar inferno that governs Earth’s climate and space environment. Understanding the Sun is not only vital for fundamental science, but also for protecting modern technology and astronauts from space weather (solar storms that can disrupt satellites and power grids) nasa.gov nasa.gov. Yet many solar mysteries endure,…

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…

Stacks of Starlink satellites awaiting deployment in orbit. A new space race is underway—not for the Moon or Mars, but to blanket Earth in high-speed internet from space. Private companies and governments are launching mega-constellations of satellites by the thousands, aiming to beam broadband connectivity to every corner of the globe. The stakes are enormous:…

High above Earth, in the crowded expanse of geosynchronous orbit (GEO) some 22,300 miles up, a set of American satellites quietly keeps watch. These are the Geosynchronous Space Situational Awareness Program (GSSAP) satellites – often dubbed “neighborhood watch” satellites – and they form a covert but crucial line of defense in space. Born in secrecy…

Low-Earth orbit (LEO) satellite internet has become a hotly contested “final frontier” of the telecom industry. Multiple players – notably SpaceX’s Starlink, the UK/India-backed OneWeb (now part of Eutelsat), Amazon’s Project Kuiper, and Canada’s Telesat Lightspeed – are racing to blanket the globe in affordable, high-speed internet from space. All seek to deliver broadband to…

Introduction High-speed internet access is increasingly seen as essential infrastructure, yet billions worldwide still lack reliable connectivity. Traditional wired broadband and cellular networks often fail to reach remote or underserved areas, leaving a “digital divide.” Enter Starlink, a satellite internet constellation developed by SpaceX. Starlink is deploying thousands of low Earth orbit (LEO) satellites to deliver…
