A brand new period of space stations is about to kick off. NASA has introduced three commercial space station proposals for improvement, becoming a member of an earlier proposal by Axiom Space.
These proposals are the primary makes an attempt to create locations for people to reside and work in space outdoors the framework of presidency space companies. They’re a part of what has been referred to as “Space 4.0,” the place space expertise is pushed by industrial alternatives. Many consider that is what it is going to take to get people to Mars and past.

There are at present two occupied space stations in low Earth orbit (lower than 2,000 km above Earth’s floor), each belonging to space companies. The International Space Station (ISS) has been occupied since November 2000 with a typical inhabitants of seven crew members. The first module of the Chinese station Tiangong was launched in April 2021, and is intermittently occupied by three crew.
The ISS, nevertheless, is slated to retire on the finish of the last decade, after practically 30 years in orbit. It has been an necessary image of worldwide cooperation following the “space race” rivalry of the Cold War, and the primary actually long-term space habitat.
Plans for a number of personal space stations signify a serious shift in how space shall be used. But will these stations change the best way individuals reside in space, or replicate the traditions of earlier space habitats?
Commercializing life in space
The change is pushed by NASA’s help for commercializing space. This emphasis actually began a few decade in the past with the event of personal cargo companies to produce the ISS, like SpaceX‘s Cargo Dragon, and personal autos to ship astronauts to orbit and the moon, reminiscent of SpaceX’s Crew Dragon, Boeing’s Starliner, and Lockheed Martin’s Orion capsules.
Start-up Axiom Space was awarded a $140 million contract by NASA in February 2020 for a personal module to be hooked up to the ISS. Axiom introduced Philippe Starck will design an opulent inside.
Starck compares it to “a nest, a comfortable and friendly egg.” There’s additionally an enormous viewing space with two-meter-high home windows for vacationers to look out at Earth and space.
The first module is because of be delivered to the ISS in 2024 or 2025, with others following annually. By the time the ISS is decommissioned round 2030, Axiom’s modules will grow to be a free-flying station.
Axiom has signed a contract with French-Italian contractor Thales Alenia Space, which constructed near 50% of the ISS’s liveable quantity for NASA and the European Space Agency, to supply its habitat.
But there’s extra. Three other groups have just been selected for the primary phase of NASA’s Commercial LEO Destinations competitors to construct free-flying space stations to exchange ISS.
First, a gaggle composed of Nanoracks, Voyager Space, and Lockheed Martin proposed a station called Starlab to offer analysis, manufacturing, and tourism alternatives. This was nearly instantly adopted by a competing project called Orbital Reef, by Blue Origin, Sierra Space, and Boeing. A third project, by Northrop Grumman, shall be fabricated from modules primarily based on its current Cygnus cargo car.
But how are space stations truly used?
Less clear is whether or not the personal space stations shall be extra habitable than earlier generations of space stations, like Salyut, Mir and ISS.
Typically, older space stations have been designed to fulfill engineering constraints slightly than beginning with crew consolation. What classes have been discovered to make life higher in space?
Until just lately, there was little analysis that targeted on the lived expertise of astronauts on space stations. That’s the place social science approaches, reminiscent of those we’re utilizing in the International Space Station Archaeological Project, are available in.

Since 2015, we’ve got developed new, data-driven understandings of how ISS crew adapt to life in a context of confinement, isolation, and microgravity. We observe and measure their interactions with constructed areas and the objects surrounding them. What are the patterns of utilization of various areas and objects?
Asking these sorts of questions reveals info by no means thought of in habitat design earlier than. It seems the crew do not essentially use the areas contained in the ISS the best way they have been designed — for instance, they personalize completely different areas with visible shows of things that mirror their beliefs, pursuits, and identification.
The crew additionally does not use all areas inside ISS equally. People from completely different genders, nationalities, and space companies seem in some modules greater than others among the many 16 that make up the station. These patterns are associated to the best way work is split up between crews and companies, in addition to the format of the modules themselves.
One massive problem of life in orbit is the shortage of gravity. Objects like handrails, Velcro, bungee cords, and resealable plastic baggage act as “gravity surrogates” by fixing objects in place whereas every little thing else floats round. Our analysis is mapping how crew adapt these gravity surrogates to make their actions extra environment friendly, and the way the position of the surrogates adjustments the best way completely different areas are used.
Society and tradition in space
Even with added luxurious options like massive home windows, designers and engineers have a protracted option to go to make space stations environment friendly, snug, and welcoming, particularly for the expected space tourism market.
The plans for privately-owned and -operated space stations are undeniably bold and will remodel how people reside on this setting. But it is seemingly that the businesses engaged on them do not but know what they don’t learn about how individuals truly use space habitats.
Only by turning in the direction of new sorts of questions and analysis from a social and cultural perspective will they be capable to make actual adjustments that may enhance mission success and crew well-being.
