Designing the next generation of multi-user commercial space stations

Context

Human spaceflight is shifting from government-run outposts to commercial stations : Axiom, Starlab, Orbital Reef, and VAST : that must pay for themselves. That changes the design problem completely. As VAST CEO Max Haot puts it, a station now has to work for “the PhD researcher AND the Instagram influencer AND the factory technician” at the same time. Government astronauts, tourists, manufacturers, and researchers all share one confined volume, each with different needs, rhythms, and tolerances.

Defining the users

Four very different users now share one pressurized volume: government astronauts on structured mission timelines; tourists there for a once-in-a-lifetime experience; manufacturers running commercial payloads; and researchers who need quiet, controlled conditions. Each arrives with different rhythms, expectations, and tolerances : and the next generation of stations has to serve all of them at once.

The problem

How can a commercial station be designed to prevent user conflict and still deliver the best possible human experience? In a confined, shared habitat, small frictions compound fast.

The conflicts

The study groups the friction into two families. Sensory conflicts: thermostat wars over a temperature no one agrees on; lighting battles between someone working and someone sleeping; noise carrying through a rigid structure; and unwanted smells with nowhere to go. Spatial conflicts: circulation congestion at pinch points, and competing claims on shared resources and spaces : one galley, one window, one exercise rack, many users.

The risk of leaving them unresolved

On a government station these are irritations. On a commercial one they are business risk: a crew that sleeps badly, works poorly, and doesn't come back. Habitability stops being a nicety : it becomes what protects the wellbeing, productivity, and repeat demand the station's economics depend on.

The ideal state

A successful multi-user station is one where four kinds of people can share a small volume for weeks without stepping on each other : where the environment quietly adapts to whoever is in a space rather than forcing a single compromise on everyone. It is a genuine testing ground for long-term human life in space.

How the study evaluates solutions

Every proposed fix is judged against five criteria: effectiveness, economic feasibility, political feasibility, technical feasibility, and flexibility and scalability. A solution that works but can't be built, funded, or scaled across a growing station doesn't count.

Proposed solutions

The study pairs a physical design move with a smart-system one for each conflict:

Noise : absorptive, curved, double-layered acoustic buffers, plus a discreet decibel-reading system that introduces AI-controlled natural soundscapes to mask disruptive sound. Temperature : sensor-driven auto-adjustment with negotiation algorithms, backed by personalized climate furniture (chairs, sleeping pods, exercise equipment) that conditions the individual instead of the whole module. Light : direct task lighting, a smart lighting system, and defined sub-zones so one person's work light isn't another's insomnia. Smell : localized capture and filtration so odors are contained at the source. Shared resources : scheduling and allocation so the galley, window, and equipment don't become flashpoints. Circulation : layouts that separate flow from dwell space to clear the pinch points.

Implementation: scalability & flexibility

Each solution is designed to scale across VAST's systems : from Haven-1 to Haven-2 and beyond : so habitability grows with the station rather than being retrofitted after the fact.

Impact

Getting the human layer right on a commercial LEO station isn't only about comfort in orbit. These are the building blocks for a multiplanetary future: the same conflicts, at larger scale, will decide whether people can live together on the Moon and Mars.

What a submarine already knows

The closest working analog to a crewed station is not another spacecraft. It is a submarine: a sealed pressure vessel where a crew lives for months, every surface carries equipment, and there is no going outside.

Inside one, the lessons are immediate. Circulation is single file, so two people passing is a design event. Every system is exposed and labelled because it has to be reached and repaired by the crew, not a ground team. Hatches between compartments are sized for a body carrying something. Nothing is finished for appearance; it is finished for maintenance.

Commercial stations are heading toward the same condition, with one difference. A submarine crew is selected, trained and ordered to be there. A commercial station carries researchers, private astronauts and staff from several operators at once, who have not spent a career learning to live in a steel tube. The interior has to do the work the training used to do.
