NASA astronaut Chris Williams conducts research operations for the Odyssey biotechnology investigation

iss074e0711160 (June 11, 2026) --- NASA astronaut and Expedition 74 flight engineer Chris Williams conducts research operations inside the Kibo laboratory module’s Life Science Glovebox for the Odyssey biotechnology investigation. The microbiology study compares bacteria samples grown onboard the International Space Station to similar samples living in simulated microgravity chambers on Earth to learn how microbes respond to space-like conditions. Insights may lead to new ways of protecting humans and equipment exposed to harsh conditions on and off Earth.
