Can life survive in the vacuum of space? What do micrometeoroids and space dust tell us about the universe? These big questions were at the heart of Japan's "Astrobiology Exposure and Micrometeoroid Capture Experiments" conducted aboard the ISS.
Led by Dr. Akihiko Yamagishi, this ambitious project sought to explore the survivability of microorganisms in the harsh environment of space and collect micrometeoroids to analyze their composition. These efforts are key to understanding panspermia—the idea that life might travel across space via comets or dust particles.
During Expeditions 43/44, 51/52, and 53/54, specially designed trays containing microbial samples were mounted on the exterior of the ISS. These samples were exposed to solar radiation, vacuum, and extreme temperatures. After months in orbit, they were returned to Earth for analysis.
In parallel, other components of the experiment captured micrometeoroids—tiny bits of rock and dust that travel through space at incredible speeds. By examining these particles, scientists hope to uncover clues about the formation of the solar system and whether organic molecules can survive interplanetary travel.
This study helps astrobiologists understand whether life on Earth could have originated elsewhere, or if life from Earth could spread to other planets. It also informs the design of spacecraft and habitats to better protect astronauts and equipment from space dust impacts.
The experiment offers insights into both the origins of life and the fundamental processes shaping the universe. It's a compelling blend of biology and planetary science.
