A Startup Is Building Data Centers in Space. Here's Why.

Cowboy Space has raised $275 million to put data centers in orbit around Earth. The company, founded in 2024 by Baiju Bhatt (who co-founded the investment app Robinhood), is now valued at $2 billion — a remarkable jump for a startup just two years old.

The company's idea sounds unusual: instead of launching traditional satellites, Cowboy Space plans to convert the upper stages of rockets into functioning data centers. After a rocket delivers its main cargo to space, that upper stage stays in orbit and runs computer servers.

How This Actually Works

Think of a rocket's upper stage as the final booster section that sits on top of a rocket. Normally, once it has pushed the main satellite or payload into space, it becomes space junk. Cowboy Space's approach is to repurpose it.

A traditional satellite is small — roughly the size of a large refrigerator or smaller. It has limited power and can overheat easily. The upper stage of a rocket, by contrast, is much bigger and has powerful solar panels and cooling systems. That gives Cowboy Space room to install actual data center equipment: servers, power systems, and the machinery needed to keep them cool in the vacuum of space.

Data centers are facilities filled with computer servers. They store and process information for companies like Google, Amazon, and Netflix. Putting one in space offers a real advantage: it can send and receive data much faster than satellites hovering far above Earth. That matters for tasks like analyzing pictures taken from space or controlling robots and drones that need to make split-second decisions.

Why This Matters Now

The space industry has changed dramatically over the past decade. Rockets have become cheaper and more reliable, making it practical to launch complex systems into orbit. At the same time, companies are hungry for new ways to store and process data — and they're running out of room on the ground.

A historical parallel helps explain this moment. In the late 1990s and early 2000s, Amazon and Google realized they could rent out their internal computer servers to other companies, creating Amazon Web Services (AWS) and Google Cloud. Today, those services power much of the internet. Cowboy Space is betting that space could be the next frontier for the same kind of business: taking expensive infrastructure and sharing it with customers.

SpaceX already did something similar with its Starlink satellite network. It started as a way to provide internet to remote areas, but has since become a platform for military communications and other services. Cowboy Space is following a similar playbook: start with one idea, then adapt it to whatever customers actually need.

The broader implication here is that space is shifting from being a domain for single-purpose missions — "launch one satellite to do one job" — to becoming infrastructure that multiple customers can use. That's a maturation of the space industry that should unlock new possibilities.

The Challenges Ahead

Launching and operating data centers in space comes with genuine complications that don't exist on Earth.

First, radiation in space damages computer chips over time. Equipment must be specially hardened to withstand this. Second, cooling a data center in the vacuum of space is not straightforward — there is no air to blow across hot components. Cowboy Space will need to use specialized cooling systems designed for this environment.

Third, power is an issue. Solar panels work well in space, but satellites pass through Earth's shadow regularly. Batteries must handle those gaps. And finally, a satellite in orbit can only "see" ground stations for brief windows — maybe ten or twenty minutes at a time, depending on its orbit. That means Cowboy Space would need to launch many platforms or work with other space companies to offer round-the-clock service.

The regulatory picture is still being written. The Federal Communications Commission (FCC) has rules for communications satellites but no established framework for computing platforms in space. Cowboy Space will need permission from both the FAA (which handles launches) and the FCC (which handles radio frequencies).

What Happens Next

The $275 million Series B round is large for such a young company, but understandable given how expensive space operations are. Even with cheaper reusable rockets, launching hardware into orbit is expensive. This capital will likely fund early demonstration missions and the design of standardized data center modules that can be deployed repeatedly.

Unlike software companies, which can grow cheaply by writing code once and selling it millions of times, space ventures require large upfront investments before any revenue arrives. The first missions will likely be test flights and proof-of-concept work with a handful of early customers.

The broader pattern worth watching: if Cowboy Space succeeds in reliably operating data centers in orbit, other companies will likely copy the model. That could open a new market where space becomes a standard part of a company's computing strategy — not a curiosity, but infrastructure, the same way cloud services are infrastructure today.
