Melagen Labs (Techstars 2024) is validating their proprietary next-gen radiation shielding for advanced cutting-edge electronics aboard the International Space Station — enabling the orbital data center economy.

When Muhammad Hunain started researching radiation effects on electronics, he wasn't thinking about space data centers. He was thinking about a fundamental problem: the electronics that power modern AI require processors that can't survive in orbit.

"Every major company building orbital data centers — from SpaceX to Google — faces the same challenge," says Muhammad, Founder and CEO of Melagen Labs. "Radiation destroys the electronics they need to run AI in space. An advanced commercial-off-the-shelf processor delivers 20 times the computing power of traditional space-rated rad-hard electronics alternatives. However, these COTS electronics are super sensitive to radiation.”

The numbers are stark. Radiation effects contribute to 38% of all satellite failures, representing over $2 billion in annual losses industry-wide. In one widely-reported ISS experiment, 11 of 20 commercial solid-state drives failed within their first year of orbital operation.

This is the problem Melagen Labs was built to solve. And now, the company is taking that solution to the International Space Station.

The Techstars Advantage

Melagen Labs joined Techstars in 2024, and the program became a catalyst for the company's trajectory. The intensive mentorship and network helped Muhammad and his team sharpen their focus on what matters: getting their shielding technology flight-validated.

"Techstars forced us to clarify the story," Muhammad says. "We had the science. We had the material. But the program helped us understand that the only thing that matters in space is flight data. You can have the best simulations in the world, but customers want to see hardware that survived in orbit."

That clarity led directly to the ISS mission. After the Techstars program, Melagen Labs was selected for the ISS National Laboratory's inaugural Orbital Edge Accelerator — one of only six startups chosen from a competitive applicant pool. The program, a collaboration between the ISS National Lab, Cook Inlet Region Inc. (CIRI), E2MC, and Stellar Ventures, provides up to $500,000 in investment alongside mentorship and the opportunity to fly an ISS National Lab-sponsored investigation.

What They're Testing

The ISS mission will deploy aboard the International Space Station later this year, using the AEGIS Aerospace MISSE (Materials International Space Station Experiment) platform for a six-month evaluation.

At the heart of the experiment is a commercial AI processor, the same class of hardware that orbital data center operators need to run inference and autonomy workloads. Melagen Labs will shield the processor with MLC1, their proprietary composite material that represents a step change in radiation shielding technology.

Unlike traditional aluminum shielding, which is heavy and generates harmful secondary radiation, MLC1 is lighter and more effective at protecting advanced electronics from radiation. The material has been validated through advanced simulations and has passed NASA's ASTM E595 outgassing standard.

The core objective is to demonstrate that a COTS AI processor, protected by MLC1, can operate reliably in orbit. The system will perform autonomous operations, including fault detection, anomaly monitoring, and onboard data management. The system will downlink time-series radiation data during flight for analysis and verification.

The ISS mission will generate the first flight-validated data proving that commercial AI processors can be protected for long-duration orbital missions.

The Partner: Satlyt and the Vision of Orbital Computing

Melagen Labs isn't flying this mission alone. They've partnered with Satlyt, a San Francisco-based startup developing distributed compute infrastructure that allows spacecraft to process, manage, and validate data directly in orbit.

For Satlyt, this mission is a foundational step toward building Virtual AI Data Centers in Space. The ISS mission provides an operational environment to test software-only payload integration, onboard data integrity under radiation conditions, resilient telemetry handling, and operational monitoring of compute resources.

Rather than positioning this as a product deployment, the demonstration serves as an in-orbit validation milestone for resilient compute infrastructure.

“This mission allows us to validate software-only integration on commercial hardware in a radiation environment,” said Rama Afullo, Founder and CEO of Satlyt. “It is an important step toward enabling distributed compute capabilities in orbit.”

Why This Matters Now

The timing of this mission couldn't be more relevant. In January 2026, SpaceX filed with the Federal Communications Commission for permission to launch up to one million satellites as orbital data centers. Blue Origin announced TeraWave, a data center-focused optical communications system. Google and Amazon have both signaled interest in space-based computing infrastructure.

The bottleneck for all of them is the same: radiation.

"Every orbital data center concept depends on running commercial processors in space," Muhammad explains. "Without effective shielding, you're forced to use radiation-hardened processors that cost 200 times more and deliver a fraction of the performance. That kills the economics of the entire business model."

Melagen Labs is positioning itself as the enabling layer for this emerging industry. The ISS experiment will generate the data that proves commercial hardware can survive, opening the door for the orbital computing economy.

The Bigger Picture

For Muhammad, the ISS mission is just the beginning. Melagen Labs is building what he calls the "full stack radiation platform," a platform that spans advanced shielding materials, AI-powered radiation software, and radiation testing infrastructure.

"Radiation is the invisible tax on everything we want to do in space," he says. "We're building the tools that eliminate that tax."

Beyond the ISS mission, Melagen has a second demonstration mission launching aboard SpaceX Transporter in 2026, deploying radiation dosimeters in sun-synchronous orbit to validate their shielding for satellite constellation applications.

Melagen Labs is a Techstars 2024 company developing next-generation radiation shielding for space electronics. The company was selected for the ISS National Laboratory's inaugural Orbital Edge Accelerator and is headquartered in New York City. Learn more at melagenlabs.com.
