Flexcompute Simulated Starlab Cabin Airflow
The partnership analyzed ventilation requirements for the upcoming commercial space station.
Updated on Oct. 6, 2026 in Space

Flexcompute has completed an initial cabin airflow study for the Starlab space station in collaboration with Starlab Space and Voyager Technologies. The simulation results successfully matched existing models for the station.
Why it matters
In microgravity, warm air does not rise and carbon dioxide can accumulate near crew members, making reliable ventilation essential for life support systems. This simulation ensures that Starlab, designed to succeed the International Space Station, maintains a breathable environment.
The simulation utilized the Flow360 computational fluid dynamics platform alongside the GeometryAI engine to automate interior modeling. This approach employs GPU-native software to map complex internal station environments.
The players
Flexcompute
This technology company specializes in high-speed computational fluid dynamics software.
Starlab Space
This company is leading the development of a commercial space station intended to replace the International Space Station.
Voyager Technologies
This firm is a partner in the development and operational planning for the Starlab space station.
The details
The team modeled the station interior using GPU-native software to simulate how air behaves in an environment where natural convection is absent. The study confirms that the digital simulation environment aligns with established performance models for the station.
Timeline

The Big Picture
This study updates the life support protocols established for the International Space Station to fit the newer Starlab design. It marks a transition in aerospace engineering toward using automated digital twins to validate safety systems in commercial orbital habitats.
Refining cabin airflow through GPU-native simulation speeds up the development of safe commercial habitats that may eventually host private researchers or tourists. These digital tools reduce the need for physical prototyping in space by identifying potential life support failures on the ground.
The takeaway
Reliable ventilation is the most critical hurdle for sustaining human life in long-term orbital missions. By successfully using automation to map airflow, developers can design safer cabin layouts before launching hardware into space.
What happens next
The project will move to a subsequent stage focused on modeling the movement and removal of carbon dioxide generated by the crew.
