HAWTHORNE, California, July 9 — For millions of people around the world, the internet remains a distant promise, a service that stops at the edge of town or refuses to cross a mountain range. SpaceX’s Starlink project is trying to change that, one satellite at a time. As of 2024, the company has placed more than 5,000 satellites into low Earth orbit, a constellation that now provides broadband service to over 2 million subscribers spread across 60 countries.
The scale of the operation is difficult to grasp. These satellites fly at altitudes between 340 and 1,200 kilometers, far lower than traditional communications satellites, which means the signal travels a shorter distance.
That translates to lower latency, a critical factor for video calls, online gaming, and real-time applications that simply cannot tolerate the lag of older geostationary systems. For patients in rural clinics who need to consult a specialist hundreds of miles away, that difference in milliseconds can be the difference between a diagnosis and a dead end.
A constellation built for coverage
Each satellite in the Starlink network is part of a carefully orchestrated mesh. They communicate with ground stations and with each other, handing off connections as they move across the sky at tremendous speed. The system is designed to cover areas where fiber-optic cables have never been laid and where cellular towers are too expensive to build.
That includes remote villages in the Global South, islands in the Pacific, and vast stretches of the Canadian Arctic. The encouraging part for patients in these underserved regions is that telemedicine, once a theoretical possibility, is now within reach.
SpaceX, the company founded by Elon Musk, has been launching these satellites in batches aboard its Falcon 9 rockets. The cadence has been relentless. By 2024, the constellation had already grown to over 5,000 units, and the company shows no signs of slowing down.
Subscribers pay for a user terminal — a flat, phased-array antenna that the system calls a Dishy — and a monthly service fee. In return, they get broadband speeds that, in many cases, rival or exceed what is available in dense urban markets.
But Starlink is not the only story here. The same company that built this satellite network is also working on something far more ambitious: Starship.
The rocket that changes the equation
Starship is not just another rocket. It is a fully reusable super-heavy-lift launch vehicle, designed from the ground up for missions that go far beyond Earth orbit. SpaceX has stated that the vehicle is intended to carry humans to the Moon and eventually to Mars.
That is the long-term vision. In the shorter term, Starship represents a fundamental shift in how heavy payloads reach space.
The first orbital test flight took place in April 2023. It was a dramatic event, watched by millions around the world. The vehicle cleared the launch tower and climbed toward space, but it did not complete its full mission.
Since then, subsequent tests have refined the design. Engineers have made changes to the stage separation system, the heat shield tiles, and the engine performance.
Each test has provided data that the company uses to improve the next iteration. Early findings suggest that the vehicle is on a path toward operational capability, though the timeline remains uncertain. For patients and their families, the connection between a Mars rocket and a cancer diagnosis may not be immediately obvious.
But the link is real. A fully reusable heavy-lift vehicle dramatically lowers the cost of putting mass into orbit. That means cheaper satellites, more frequent launches, and a constellation that can be replenished faster and more affordably.
When a Starlink satellite reaches the end of its life, it deorbits and burns up in the atmosphere. A new one takes its place.
With Starship, that replacement cycle becomes faster and cheaper, which means the network stays robust.
A lunar contract and a planetary vision
In 2021, NASA awarded SpaceX a $2.9 billion contract to develop Starship as a lunar lander for the Artemis program. That program aims to return humans to the surface of the Moon for the first time since the Apollo era. Starship is not just a delivery truck for satellites.
It is being built to carry astronauts down to the lunar surface, to support extended stays, and to serve as a platform for scientific research. The contract is one of the largest single awards in NASA’s history, and it signals the agency’s confidence in SpaceX’s approach.
The Artemis program has faced delays, as all large space programs do. But the work continues. Starship prototypes have undergone static fire tests, pressure tests, and short-hop flights at the company’s facility in Boca Chica, Texas.
The vehicle is enormous. When fully stacked atop its Super Heavy booster, it stands taller than the Saturn V rocket that carried astronauts to the Moon in the 1960s.
The design is stainless steel, a choice that reflects the vehicle’s intended use in extreme thermal environments. For the Starlink project, Starship offers a crucial capability: the ability to launch larger batches of satellites in a single mission. The current Falcon 9 can carry about 60 Starlink satellites per launch.
Starship, with its cavernous payload bay, could carry several times that number. That would accelerate the buildout of the constellation and allow SpaceX to deploy next-generation satellites with more advanced capabilities, including direct-to-cellphone connectivity that could eliminate the need for a ground terminal in some situations. Patients should understand that these are not abstract engineering feats.
When a rural health clinic in Pakistan or Kenya gains reliable broadband through Starlink, it gains access to the same medical literature, the same specialist consultations, and the same diagnostic tools that are available in a major hospital in Karachi or Nairobi. The constellation is already operational in 60 countries.
The number of subscribers has passed 2 million. Those are not small numbers. The encouraging part is that the technology is still evolving.
The satellites themselves have been upgraded over time. The first generation had a limited lifespan and a relatively simple design.
The newer versions include laser inter-satellite links, which allow data to travel from one satellite to another across the globe without touching a ground station. That means a signal from a remote village in the Himalayas can hop from satellite to satellite and reach a specialist in Islamabad without ever coming down to Earth until it reaches its destination. There are challenges, of course.
Astronomers have raised concerns about the brightness of the satellites and their impact on ground-based observations. SpaceX has responded by testing darker coatings and sunshades, though the issue is not fully resolved. There are also regulatory hurdles in some countries, where local telecommunications laws require partnerships with domestic providers.
And the cost of the user terminal, while it has come down, remains a barrier for many households in low-income regions. But the trajectory is clear.
The constellation is growing. The rocket that will sustain it is being tested. The contract with NASA provides both funding and a clear mission objective.
For patients who live in areas where internet access has historically been unreliable or nonexistent, the message is one of cautious hope. Talk to your doctor about whether telemedicine services are available in your area.
Ask whether your clinic has considered satellite-based connectivity. The infrastructure is being built. It is not a promise for some distant future.
It is happening now.
