Flexcompute is collaborating with Starlab Space and Voyager Technologies (NYSE: VOYG) to model cabin airflow inside Starlab’s planned commercial space station.

The work supports the station’s Environmental Control and Life Support System, which circulates air throughout the cabin. Flexcompute used Flow360 and GeometryAI to model the full station interior. The company said the first study closely matched Starlab’s existing models in less time than traditional computational fluid dynamics tools. The teams are now extending the work to model how crew-exhaled carbon dioxide moves through the cabin and how the life support system removes it.

eclss technical

"Environmental Control and Life Support System (ECLSS)"

ECLSS stands for Environmental Control and Life Support System, the collection of equipment and subsystems that keep a closed human environment habitable by controlling air composition and pressure, temperature, humidity, and by managing water and waste. It typically includes oxygen generation and carbon-dioxide removal, air circulation and filtration, thermal control, and water recovery; because it operates in closed or isolated settings, it must provide redundancy and regular maintenance to prevent system failures that would immediately affect occupant safety.

computational fluid dynamics (cfd) technical

"computational fluid dynamics (CFD) platform"

Computational fluid dynamics (CFD) is a computer-based technique that uses mathematical models to simulate how liquids and gases move and carry heat around objects, like a virtual wind tunnel or weather forecast for parts. For investors, CFD matters because it can cut physical testing, speed design cycles, reduce engineering surprises and compliance risks, and lower development costs—factors that influence product success, capital needs and time to revenue.

microgravity technical

"In microgravity, warm air does not rise"

Microgravity is a condition where objects experience almost no net weight because they are in continuous free-fall, such as aboard orbiting spacecraft; think of passengers feeling weightless in a smoothly falling elevator. For investors, microgravity matters because it enables scientific experiments and manufacturing processes that behave very differently than on Earth, potentially creating novel drugs, materials, or technologies, changing development timelines, costs, market opportunities and regulatory considerations.

Leading CFD platform provider helps Starlab's life support team model airflow inside the commercial successor to the International Space Station

BOSTON, Oct. 6, 2026 /PRNewswire/ -- Flexcompute, the physics company, today announced it is collaborating with Starlab Space and Voyager Technologies (NYSE: VOYG) to simulate cabin airflow inside Starlab, the commercial space station designed to succeed the International Space Station (ISS).

On a space station, air does not move on its own. In microgravity, warm air does not rise, and the carbon dioxide crew members exhale can linger around them unless the ventilation system keeps it moving. Starlab's Environmental Control and Life Support System (ECLSS) has to circulate fresh air through every part of the station and keep the crew comfortable. Because Starlab is designed to launch in a single flight, that design has to be right before it leaves the ground.

Flexcompute used Flow360, its GPU-native computational fluid dynamics (CFD) platform, and GeometryAI, its automated geometry preparation engine, to model airflow across the full station interior. The first study closely matched Starlab's existing models in a fraction of the time traditional CFD tools take. The teams are now extending the work to model how the carbon dioxide crew members exhale moves through the cabin and how the life support system removes it.

"Building a commercial space station takes partners who move at our pace," said Jonathan O'Neill, Atmosphere Management System Lead at Starlab Space. "Flexcompute's engineers paved new ground in cabin ventilation CFD. That level of expert support gives us more confidence as Starlab moves from design into production."

"Life support airflow can't be fully tested on the ground, so simulation carries much of the design work," said Vera Yang, Co-founder and President of Flexcompute. "Working with Starlab's ECLSS team shows what GPU-native physics makes possible for commercial space: faster answers, earlier in design, so engineers can move forward with confidence."
