Multiple studies demonstrate that certain Earth-based lifeforms, such as specific bacteria, fungi, and extremophiles like tardigrades, possess the physiological adaptations necessary to survive the harsh vacuum and conditions of outer space.
The retrieved literature includes direct experimental evidence demonstrating that microorganisms like Bacillus subtilis and Aureobasidium pullulans can survive extended periods of exposure in the vacuum of outer space near the International Space Station. Furthermore, extensive research on extremophiles like tardigrades documents cryptobiotic mechanisms that allow them to endure extreme desiccation and vacuum-like stressors, clearly supporting the claim.
