Agnirva Space Premier League - Expedition #30052: Unveiling the Space Microbiome: Animal-Microbe Interactions in Microgravity

Microgravity changes everything—even the tiny world of microbes and their interactions with animal hosts. The experiment “Understanding of Microgravity on Animal-Microbe Interactions,” led by Dr. Jamie Foster from the University of Florida, investigates how spaceflight alters the symbiotic relationships between animals and the microbes that live inside them.

Our bodies are home to trillions of microbes that support digestion, immune defense, and overall health. On Earth, these relationships are well studied. But what happens when gravity is taken out of the equation?

Conducted during Expedition 65, this research involved sending animal models and their microbiomes to the International Space Station. The team studied how microgravity affects microbial behavior and the animal's immune responses. Early findings suggest that microgravity might weaken immune functions or shift microbial populations, which could have serious implications for astronaut health during long-duration missions.

Understanding these shifts is also crucial for planning future deep-space missions to the Moon and Mars, where astronauts will need to stay healthy for extended periods. Additionally, this research offers insights into how gut bacteria may be influenced by stress or environmental change—useful knowledge for medicine and biotechnology on Earth.

By studying life on the microscopic scale in space, we can better protect astronauts and improve life on Earth.
