Scientists have discovered a new species of bacteria adapted to space, found on China’s Tiangong space station. The microbe, named Niallia tiangongensis, was identified in samples taken from the space station during the Shenzhou 15 mission.
The new species is characterized as aerobic, spore-forming, and rod-shaped. It is closely related to bacteria that cause infections on Earth and has developed unique adaptations to survive in the harsh space environment.
Researchers found that Niallia tiangongensis has a heightened oxidative stress response and can form biofilms to repair radiation damage. These adaptations set it apart from its terrestrial relatives.
The discovery was made possible by regular microbial sampling on Tiangong, which aims to monitor the space station’s environment. This research contributes to understanding microbe behavior during long-term space missions and safeguarding astronaut health.
Previous discoveries of novel species in space include bacteria found on the International Space Station, some of which could help astronauts grow crops on Mars. The study highlights the importance of studying microbes in space to ensure a safe and functional spacecraft environment.
