In today's episode of Discover Daily, we explore how Earth bacteria demonstrated remarkable adaptability by rapidly colonizing samples from the asteroid Ryugu, despite rigorous containment protocols. The Japanese Hayabusa2 spacecraft's samples, initially microbe-free, saw bacterial growth expand from 11 to 147 organisms within a week of Earth exposure, raising important questions about containment methods for future space missions and our u...
