Starlink Explained: Satellite Internet

Starlink is SpaceX's low-orbit broadband network. Here is how the dish, the constellation, coverage, speeds, and use cases work, in plain language.

Starlink is a satellite internet service run by SpaceX. It delivers broadband through thousands of low-orbit satellites, which connect to a small dish at the customer’s home.

The service is designed for places cable and fiber don’t reach, rural properties, boats, remote worksites, and disaster zones where ground networks are unavailable. Traditional satellite internet relies on satellites nearly 36,000 kilometers above Earth. Starlink’s satellites orbit just a few hundred kilometers overhead, making the connection feel much faster. That lower orbit is the key difference between Starlink and the satellite internet of a decade ago.

Starlink connects a customer to the internet through three pieces: the dish, the constellation, and the ground gateways. The dish, a flat panel SpaceX nicknames “Dishy,” sits with a clear view of the sky and steers its beam electronically to track satellites as they pass. There are no moving parts to point it. The panel aims itself.

The dish talks to whichever satellite is overhead, and because those satellites are in low Earth orbit, each one is only in view for a few minutes. So the dish hands off to a fresh satellite constantly as the fleet moves across the sky. The satellite then relays the traffic to a ground gateway wired into the internet, or passes it between satellites using laser links in space before it comes down. Our LEO satellites explainer covers why low orbit forces this constant handoff and why it needs so many satellites to work.

The Constellation

Starlink is the largest satellite constellation ever flown, with thousands of satellites in orbit as of 2026 and more launching regularly. The scale is the product. A low-orbit satellite covers only a small patch of ground at any moment, so continuous service everywhere demands a very large fleet spread across many orbital planes. SpaceX launches its own satellites on its own rockets, which lets it add to the constellation faster and more cheaply than operators that must buy launches from someone else.

Because the fleet is always growing and older satellites are always being retired, the exact satellite count is a moving target. The satellites fly low enough that a dead one is dragged down by the faint atmosphere and burns up within a few years rather than lingering as debris. That short lifespan means SpaceX has to keep launching replacements just to hold the network steady, on top of the launches that expand it.

How Starlink’s shell compares with Iridium, GPS, and China’s networks is laid out in our satellite constellations guide.

Coverage, Speeds, and What to Expect

Starlink typically advertises download speeds in the tens to low hundreds of megabits per second, with latency that is low, roughly tens of milliseconds. Those figures are enough for video calls, streaming, and gaming, uses that older satellite internet handled poorly because of its long delay. Real performance shifts with conditions, so the numbers are a guide rather than a guarantee.

Two factors move the actual speed a user sees. The first is congestion: satellite capacity over any area is shared, so speeds can dip when many subscribers in the same region are online at once. The second is weather, since heavy rain or snow weakens the high-frequency signal the dish uses. Coverage depends on the satellites overhead and on local regulatory approval, and it has widened fast, though some areas remain waitlisted. Anyone considering it should check the official coverage map for a specific address before ordering.

Use Cases

Starlink fits wherever the ground network falls short. Its clearest home is rural and remote broadband, where a property sits beyond the reach of cable or fiber and the only prior option was slow, high-latency satellite. It also serves motion: boats, recreational vehicles, and aircraft use versions of the service built to keep a link while moving. Anyone still deciding whether the cost makes sense can see our full breakdown of whether Starlink is worth it. After a hurricane or wildfire knocks out local towers, portable Starlink terminals often restore connectivity for responders within hours.

The service comes in tiers built for these different uses. A residential plan ties service to one address and costs the least. Mobile and maritime plans cost more but keep the link while the terminal travels, and business plans add priority data so a paying site is less likely to slow down when an area gets busy. The hardware differs too: a boat or a plane in constant motion needs a sturdier, higher-performance dish than a fixed roof mount. Anyone weighing the service should match the plan to how they will actually use it, since paying for mobility a fixed home never needs is wasted money. What each tier costs, whether it carries a data cap, and how the hardware price shifts by region, is on our Starlink pricing page.

Beyond home internet, Starlink runs a separate direct-to-cell service that connects ordinary phones for texting from dead zones, using cell payloads on its satellites and partnerships with mobile carriers. That service starts with messages rather than the full broadband the dish delivers, because a bare phone cannot hold the strong link a dish can. Starlink now calls that phone service Starlink Mobile; see whether you can get Starlink Mobile on your phone and which phones work with Starlink.

Starlink is not the only satellite broadband option, and the alternatives split along the low-orbit versus high-orbit line.

ProviderOrbitLatencyPosition as of 2026
StarlinkLow Earth orbitLow, tens of msLargest fleet, consumer and enterprise
OneWebLow Earth orbitLowEnterprise and government focus
Project KuiperLow Earth orbitLowAmazon network, deploying
ViasatGeostationaryHigh, ~500 msEstablished high-orbit broadband

The low-orbit rivals, OneWeb and Amazon’s Project Kuiper, share Starlink’s latency advantage but sit at different stages and chase different customers. OneWeb, now part of Eutelsat, leans toward enterprise and government users. Project Kuiper is still building out its fleet, and our Project Kuiper explainer covers its deployment progress and FCC deadline status in detail. Geostationary providers such as Viasat cover wide areas with far fewer satellites, but their high orbit adds the long delay that low-orbit networks were built to avoid. SpaceX also sells a government-only line on the same hardware, and whether Starshield is the same thing as Starlink is the question that separates them.

For plan-by-plan comparisons with the geostationary incumbents, see Starlink vs HughesNet and Starlink vs Viasat.

Each Starlink satellite is designed for roughly five years of service, after which SpaceX plans to retire and replace it rather than keep it flying indefinitely. When a satellite reaches the end of its life or fails early, SpaceX uses its onboard thrusters to actively lower the orbit until the satellite burns up in the atmosphere within weeks, a controlled disposal that goes well beyond the 25-year international guideline for clearing dead satellites out of orbit. Even a satellite that fails completely and cannot maneuver still reenters naturally within one to two years, because Starlink flies low enough, around 500 to 550 kilometers, for the thin remaining atmosphere to drag it down on its own.

That short lifespan is a tradeoff SpaceX accepted deliberately. A satellite has to keep launching replacements just to hold the constellation steady, on top of whatever growth is planned, but flying low keeps latency down and guarantees that a dead satellite does not linger as space debris for decades the way a geostationary one would.

Satellite Generations: V1, V2 Mini, and V3

SpaceX has flown three broad generations of Starlink hardware, each heavier and more capable than the last. The original V1 satellites, at roughly 260 kilograms each, made up the early constellation and are now mostly retired through the controlled deorbit process described above. The V2 Mini generation that followed weighs about 800 kilograms, carries more capacity per satellite, and added the direct-to-cell payload that lets ordinary phones connect without a dish. V2 Mini also switched to argon-fueled Hall-effect thrusters, which SpaceX’s own documentation states deliver more than double the thrust of the earlier krypton-fueled engines.

The newest generation, V3, is built around Starship rather than Falcon 9 as its launch vehicle, since its larger size and roughly tenfold jump in per-satellite capacity over V2 Mini would not fit efficiently inside Falcon 9’s smaller payload bay. Starship’s higher payload capacity is what makes a satellite that size worth building in the first place.

Starlink is a business unit of SpaceX rather than a separately listed company. SpaceX itself went public on June 12, 2026, and now trades on the Nasdaq under the ticker SPCX, but that listing covers the combined company, launch, Starlink, and SpaceX’s newly acquired xAI operations, together. There is still no Starlink-only ticker to buy separately. SPCX is currently the only public-market way to gain exposure to Starlink’s satellite-internet business.

Frequently asked questions

What is Starlink?

Starlink is a satellite internet service run by SpaceX. It uses thousands of satellites in low Earth orbit to deliver broadband to a small dish at the customer's location, aimed at places that fiber and cable lines never reached.

How fast is Starlink?

Starlink typically advertises download speeds in the tens to low hundreds of megabits per second and latency that is low, roughly tens of milliseconds. Real speeds vary with how many users share a given area and with weather, so treat any single number as a rough guide as of 2026.

Do you need a dish for Starlink?

Yes. Standard Starlink service uses a flat, self-aiming dish that steers its signal to track satellites overhead. Starlink also runs a separate direct-to-cell service that talks to ordinary phones for texting, but home internet still relies on the dish.

Is Starlink available everywhere?

Not everywhere. Coverage depends on how many satellites serve a region and whether the local government has approved the service. Availability has widened quickly, but some areas remain waitlisted or unapproved, so it is worth checking the coverage map for a specific address.

Is Starlink publicly traded?

Not separately. Starlink is part of SpaceX, which went public on the Nasdaq under the ticker SPCX in June 2026, but that listing covers the whole company rather than carving out a standalone Starlink ticker. Buying SPCX is currently the only public-market way to gain exposure to Starlink, alongside SpaceX's launch and xAI businesses.

How does Starlink compare to Amazon's Project Kuiper?

Starlink and Project Kuiper both fly in low Earth orbit and target similar latency, in the tens of milliseconds. Starlink already has the larger fleet in service and serves both consumer and enterprise customers, while Kuiper is still deploying its constellation and has not yet reached Starlink's coverage or scale. The two behave more alike than either does compared to a geostationary provider like Viasat, which orbits far higher and carries a much longer delay. Our Amazon Leo vs Starlink comparison puts the two services side by side.

How much does Starlink cost a month?

In the United States, Starlink residential service costs $55 a month for 100 Mbps, $85 a month for 200 Mbps, and $130 a month for Residential Max, all with unlimited data as of September 2026. Roam plans cost $55 a month for 100 GB, $80 for 300 GB, or $175 for Roam Unlimited, while Business plans start at $55 a month with adjustable priority-data blocks. Hardware is a separate one-time purchase and pricing varies by region and account, so verify current rates for your address on Starlink's service plans page.

Is Starlink better than 5G?

Whether Starlink is better than 5G home internet depends on coverage. Fixed wireless 5G from cellular carriers requires reasonable proximity to a cell tower and cannot reach the most remote areas Starlink serves. Starlink targets regions without cable, fiber, or cellular tower infrastructure, advertising download speeds in the tens to low hundreds of megabits per second (Mbps) with latency of roughly tens of milliseconds. Where cell towers reach, 5G delivers residential connectivity, while Starlink connects locations where ground infrastructure does not exist at all.

What is the downside to Starlink?

Starlink's main downsides are shared bandwidth, weather sensitivity, and cost tiers. Speeds dip when many subscribers in the same area are online at once, and heavy rain or snow weakens the signal. Some areas also remain waitlisted where local approval or satellite coverage hasn't caught up, and the mobile and maritime plans built for motion cost noticeably more than the residential tier. None of that is unique to Starlink among satellite internet providers, but it is why the service still trails wired fiber on consistency.

Does Starlink cause light pollution or interfere with astronomy?

Yes, Starlink satellites interfere with optical astronomy by leaving bright streaks across long-exposure images, especially shortly after launch and around dawn or dusk when visible to the naked eye. Wide-field survey telescopes like the Vera C. Rubin Observatory are particularly exposed, so SpaceX tested experimental DarkSat coatings and VisorSat sun-visors to reduce ground brightness. The International Astronomical Union also established the IAU Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference to coordinate solutions with satellite operators.
