Evolving bacteria on Tiangong station threatens future space missions

Scientists have identified a new, evolving bacteria, Niallia tiangongensis, aboard China's Tiangong space station, raising concerns about potential risks to future space missions. The bacteria, discovered during a 2023 mission, exhibits remarkable adaptation to space's harsh conditions, including radiation resistance and biofilm formation, which could protect it from cleaning methods. While currently harmless, its evolution in space is a major concern. Researchers are studying the bacteria's genome, fearing it could mutate into a threat to astronauts or spacecraft. This discovery highlights the need for stricter microbial monitoring as humans plan deeper space exploration.
