Russian state-owned company Energia has achieved a significant milestone by securing a patent for a new spacecraft design that aims to create artificial gravity. This innovation could greatly enhance the experience of astronauts on long-term missions.
This patent, reported by TASS, details a rotating system capable of generating a gravitational force equivalent to 50% of Earth’s gravity. The design features a central module with both static and rotating elements, connected by flexible joints to radially attached habitats.
To produce this artificial gravity, the attached modules would need to rotate around the central axis at five revolutions per minute. Each habitat would require a radius of around 131 feet (40 meters). Such a large structure would necessitate multiple launches and assembly in orbit.
One challenge identified in the design is the complexity of coordinating the rotation of transport ships for safe docking. This factor raises safety concerns for potential use.
Artificial gravity could significantly impact astronauts during lengthy missions, like those to Mars or other deep-space destinations. Prolonged exposure to microgravity can lead to various health issues, including muscle weakening and loss of bone density. Recent studies have shown that astronauts can lose up to 1% of their bone density per month in microgravity environments, making artificial gravity an appealing solution for future space exploration.
NASA is exploring similar concepts. Their Nautilus-X space station design includes rotating components aimed at generating artificial gravity. More recently, the private company Vast has also expressed intentions to develop artificial gravity stations.
While Energia’s patent shows a strong interest in artificial gravity, specific timelines and funding for this new project have not been disclosed. However, it comes at a critical time when the International Space Station (ISS) is nearing its end, with plans for decommissioning scheduled for 2030.
As it stands, NASA and Roscosmos intend to retire the ISS by 2030, using a modified SpaceX Dragon capsule for its final descent. Russia has committed to remain part of the ISS program until at least 2028. This transition period marks an exciting phase in space exploration, filled with innovative designs like Energia’s that could shape the future of human space travel.
