Satellite Internet
The Sky Is Now Full of Routers (And That Changes Everything)
For most of human history, the people least connected to the world were the ones who needed connection the most — that calculus is now being rewritten, 550 kilometres above your head.
The Idea
The idea behind satellite internet isn't new — we've had geostationary satellites beaming data since the 1990s. But those systems had a fundamental, physics-baked problem: the satellites sat roughly 35,000 kilometres up, in a fixed orbit above the equator. At that distance, the time it takes a signal to travel up and back down — latency — is around 600 milliseconds. That half-second delay doesn't sound catastrophic until you're on a video call, playing a game in real time, or, critically, running a hospital consultation in a remote area. What changed the game wasn't a software fix or a clever algorithm. It was orbital altitude. A new generation of low Earth orbit, or LEO, constellations — satellites circling at 550 to 1,200 kilometres — cut that latency to somewhere between 20 and 40 milliseconds. That's in the same ballpark as a decent fibre connection. The satellites move fast (they lap the Earth roughly every 90 minutes), so you need hundreds or thousands of them working in coordinated relays to maintain continuous coverage. This is why these systems are called constellations — one satellite hands off your connection to the next, almost imperceptibly. The engineering required is staggering: each satellite is essentially a flying radio tower with sophisticated phased-array antennas, powered by solar panels, and communicating both with the ground and with neighbouring satellites. The cost that once made this unthinkable — launching a single satellite used to cost hundreds of millions — has collapsed alongside launch prices, which is what made the whole enterprise viable.
In the World
In February 2022, within days of Russia's invasion of Ukraine, ground-based internet infrastructure began going dark. Cell towers were destroyed. Fibre lines were cut. In some cities, entire neighbourhoods lost connectivity overnight. Within 48 hours, Mykhailo Fedorov, Ukraine's Minister of Digital Transformation, sent a now-famous tweet tagging SpaceX's Starlink service, asking for terminals. Within days, thousands of terminals were on their way. Within months, Starlink terminals were being used by Ukrainian military units for targeting, communication, and drone coordination — in places where no terrestrial network existed. It was the first large-scale demonstration of LEO satellite internet being used not as a convenience, but as critical wartime infrastructure. Military analysts described it as a genuinely novel development in the history of communications in conflict. But the implications stretch far beyond conflict zones. In the Amazon basin, indigenous communities that had never had a stable broadband connection began accessing telehealth services. In Alaska, schools that were running on satellite connections with 700-millisecond delays suddenly had latency low enough to run live video lessons without the conversation becoming a pantomime of frozen frames and awkward pauses. In maritime shipping, vessels that used to go dark for days at sea are now continuously connected. The technology isn't perfected — it's expensive, weather can degrade it, and the terminals aren't small — but the proof of concept is now undeniable.
Why It Matters
The geography of internet access has always roughly mirrored the geography of wealth and density. Cities got fibre first. Suburbs got decent broadband eventually. Rural and remote areas got promises. That pattern isn't incidental — laying physical cable is expensive, and the economics have never favoured sparse populations. LEO constellations cut that cord, so to speak. The economics of satellite coverage don't care whether you're in central London or central Chad. That matters for how you think about the next decade. The assumptions we've built around digital access — that the unconnected are simply late adopters waiting for infrastructure to arrive — may be wrong. The infrastructure may arrive from above, on a timeline compressed by launch economics rather than by the slow politics of building ground infrastructure. It also raises harder questions: who controls the sky? If the communications of a country under attack can be switched on or off by a private company's decision, what does sovereignty mean in a LEO-connected world? The technology is genuinely liberating. The power structures it creates are genuinely new. Both things are true at once.
A Question to Ponder
If reliable internet access becomes available everywhere on Earth simultaneously, which assumptions about development, education, or democracy — that you've quietly held as fixed — would have to change first?
