57. Data Centers in Orbit: How Madari Space Wants to Move Your Data Off the Planet

Shareef Al-Romaithi almost became an astronaut. Twice he made it to the final rounds of the UAE's astronaut selection program, and twice he came up short. Instead of walking away from the space sector, he found a different door into it, and that door turned out to be data.

Al-Romaithi is the founder and CEO of Madari Space, an Abu Dhabi startup building a constellation of data centers in low Earth orbit. His pitch is simple: the internet's data problem cannot be solved by building more warehouses full of servers on Earth. It has to be solved by leaving Earth.

The scale of the problem is what makes the idea less crazy than it first sounds. As Al-Romaithi put it, "the global network of data centers, and I believe today we have we are getting close to 12,000 data centers, they emit more carbon than the entirety of airline industry, which is completely shocking." Add in the water used for cooling, water that "once it has been used there's no way to re-recycle," and the environmental case for rethinking data infrastructure becomes hard to ignore.

From cockpit to cosmos

Before any of this, Shareef flew commercial aircraft for Etihad. A setback in his astronaut ambitions pushed him toward a master's degree in space operations, and that program reframed how he saw the industry. Space, he realized, was no longer the exclusive territory of governments and giant contractors. Universities were launching CubeSats, private investors were funding startups, and Earth observation was becoming a commercial business in its own right.

Madari Space launched in 2023, the UAE's self-declared "year of sustainability," with a mission to tie space operations to the country's environmental goals. But the company's ambitions have since expanded into three phases: giving governments and enterprises an off-planet backup layer for critical data, supporting the infrastructure demands of the AI boom, and only then circling back to the original sustainability mission.

What a data center in orbit actually looks like

Forget the image of a glass building floating above the clouds. Madari's first satellite is a 12U cube, roughly ten centimeters per unit, orbiting 500 to 600 kilometers above Earth. "Think of it as Starlink, but instead of internet, we're providing data capacity and data processing," Shareef explained. The long-term vision could evolve into a more centralized hub at higher orbit, and eventually into deep space storage at points that tap into what he calls the cislunar economy.

The first customers will not be individuals uploading vacation photos. They will be governments and large institutions looking for a redundancy layer, a copy of their most critical data sitting somewhere no flood, war, or cyberattack on Earth can reach. Shareef pointed to a telling real-world example: the UAE's central bank was granted a waiver to store data in Sweden as a business continuity measure. Madari's argument is that even that solution is still tied to terrestrial infrastructure, and therefore still vulnerable. "By moving the data to space as a fail-over layer, or as a perhaps third or fourth copy of what you have on Earth, this provides you the assurances that you need as a government."

Radiation, heat, and the hardest engineering problem in the room

Space is not a cooling solution, even though there is no water and no heat there to worry about. It is arguably a harder thermal problem than Earth. "I believe that cooling is still a challenge in space, mainly because you're operating in a vacuum environment. Space is a harsh environment, we're not meant to be there, not us, not our hardware," Shareef said. Madari is developing heat pipes to dissipate warmth into space and building software that limits processing loads to reduce heat generation in the first place.

Radiation is the other major threat, since exposure can corrupt or permanently destroy stored data. The company was preparing a radiation test campaign in Switzerland just days after this conversation was recorded, stress-testing hardware components to understand exactly how much exposure they can survive before failure.

A constellation, not a single point of failure

Madari's answer to nearly every question about risk is the same: decentralization. Rather than one large orbital data hub, the company is building a distributed network of smaller units that communicate with each other using laser links, with data able to migrate autonomously if a single node is damaged or threatened by debris. The same philosophy extends to launch partners. Madari is deliberately working with providers in Europe, Korea, and China rather than relying on a single company, a strategy Shareef frames bluntly: "You always need to have contingency plans, this is for the sake of your success, for the sake of comforting your investors, and of course to ensure your business continuity as you scale your business in the future."

The regulatory frontier

One of the more interesting tensions in the conversation is how laws written for a planet apply once data leaves it. Frameworks like Europe's GDPR were built around the idea that data has a jurisdiction. Orbit complicates that. Shareef's answer leans on cybersecurity architecture rather than legislation for now, including zero trust and zero knowledge proof systems, plus a partnership with a layer-one blockchain provider, so that "even though we have your data, we have no access to it and we don't know what is it."

Low Earth orbit as a stepping stone

Shareef sees this as only the beginning. He described low Earth orbit as a proving ground before humanity pushes further, toward the Moon and eventually a cislunar economy. The UAE is already contributing an airlock to NASA's Gateway station, and Shareef expects data infrastructure to eventually follow humans there too.

Asked what the relationship between humans and space looks like decades from now, his answer was direct: space stops being a frontier for exploration alone and becomes a primary operational sector, one where data centers play a central role.

For Mizter Rad, the through-line connects directly to a conversation with Canadian Space Mining Corporation's Daniel Sax, who made the case that the extreme constraints of space, radiation, temperature, and the total absence of resources, force engineers to invent solutions that eventually solve problems back on Earth. Shareef's answer confirmed the pattern extends even to something as unglamorous as data storage. It's a theme that also echoes conversations about how synthetic biology could one day let people store their genomic data for future use, a topic explored with Andrew Hessel on the show.

The bigger question Shareef leaves listeners with isn't really about satellites. It's about ownership. As more of daily life becomes digital, from medical records to national archives to the outline of a person's own biology, the question of who controls that data, and where it physically lives, stops being abstract. Soon, some of it may be orbiting 500 kilometers over our heads.
