Russian state-owned Energia rocket company has secured a patent for a novel spacecraft architecture designed to generate artificial gravity, a capability which could provide a huge boost for long-duration crewed missions.

A report from Russian state media outlet TASS, which obtained the patent, states that the rotating system is designed to generate a gravitational force of 0.5g, or 50% of Earth’s gravity. The patent documentation includes illustrations of a notional space station structure with a central axial module with both static and rotating components, with modules and habitats connected by a hermetically sealed, flexible junction.

The documentation notes the disadvantage of the need for spinning and coordinating the rotation of transport ships to dock with the station, which it notes reduces the safety of using such a station.

Generating artificial gravity could have profound impacts for crews on long-duration space missions, whether in low Earth orbit on interplanetary voyages into deep space. Exposure to microgravity has numerous impacts on astronauts, including muscle atrophy and bone density loss.

NASA has produced concepts such as the rotating wheel space station concept Nautilus-X, while, more recently, commercial firm Vast has said it will pursue artificial gravity stations.

Russia did not indicate timelines for such a project nor resources to back its development. The patent does however indicate interest in the concept of artificial gravity at a time when the end of the International Space Station (ISS) is approaching and new national and commercial station plans are moving forward.

Currently, NASA and Roscosmos plan to deorbit the ISS in 2030, to push the station down into a fiery death over the Pacific Ocean. Russia has committed to stay aboard the ISS .
