Aerospace Company Airbus Designs New Space Station With Artificial Gravity

The International Space Station (ISS) is nearing the end of its service. While NASA and its partners have committed to keeping it in operation until 2030, plans are already in place for successor space stations that will carry on the ISS’ legacy.

China plans to assume a leading role with Tiangong, while the India Space Research Organization (ISRO) plans to deploy its own space station by mid-decade. NASA has also contracted with three aerospace companies to design commercial space stations, including Blue Origin’s Orbital Reef, the Axiom Space Station (AxS), and Starlab.

Well, buckle up! The European multinational aerospace giant Airbus has thrown its hat into the ring!

In a recently-released video, the company detailed its proposal for a Multi-Purpose Orbital Module (MPOP) called the Airbus LOOP. This modular space segment contains three decks, a centrifuge, and enough volume for a crew of four, making it suitable for future space stations and long-duration missions to Mars.

The LOOP builds on the company’s long history of human spaceflight programs, like the ISS Columbus Module, the Automated Transfer Vehicle (ATV), and the Orion European Service Module (ESM).

As you can see from the video below, the interior design consists of three levels (or decks). These include (from top to bottom) a Habitation Deck, a Science Deck, and a Centrifuge that simulates gravity for two crewmembers at a time.

The module measures 8 meters (about 26 feet) in diameter and roughly the same length, providing close to 100 cubic meters (~3500 cubic feet) of volume.

According to Airbus, separating the interior into different decks allows for an “internal safe harbor concept,” meaning that the crew can move to the deck that affords the most protection in the event of a solar flare or other hazards.

Each deck is accessible via a central “Tunnel” surrounded by a greenhouse structure that can accommodate plant experiments and provide a steady supply of supplemental greens, legumes, and other plants (similar to greenhouses aboard the ISS).

The module is designed for a crew of four but can reportedly accommodate up to eight astronauts at a time (temporarily).

The deck selection can be adapted to individual mission requirements and objectives, or the mechanical structure can be used alone (a “dry module”).

Individual decks can be equipped with mission-specific machinery and infrastructure depending on the mission requirements.

In the standard design, the Habitation Deck is essentially a “common area” with large windows and exercise equipment (stationary bikes).

The Science Deck is equipped with multiple computer terminals, an airlock that allows the crew to conduct extra-vehicular activities (EVAs), and smaller portholes to provide views of space.

But what is perhaps the most interesting element of the LOOP is the Centrifuge, which consists of two weights and two crew pods. These pods contain exercise bikes and can accommodate a single crewperson, allowing the crew to work out (two at a time) in a simulated gravity environment.

This three-deck design meets all of the basic needs of long-duration stays in space and (according to Airbus) makes the LOOP compatible with all crew and cargo vehicles, including those currently in service and those in development. This includes the ISS, where the LOOP would be integrated to provide additional volume and even “gravity therapy.”

It could also be integrated into the Lunar Gateway or could act as the habitation module of the proposed Deep Space Transport (DST).

Airbus also emphasizes that multiple LOOP modules can be combined to create a full-on space station, each outfitted with various decks to accommodate a range of operations and experiments. In this respect, the LOOP could occupy a role similar to what NASA had in mind with his proposed Non-Atmospheric Universal Transport Intended for Lengthy United States Exploration (Nautilus-X) concept.
