iss073e0886460 (Oct. 20, 2025) --- NASA astronaut and Expedition 73 Flight Engineer Zena Cardman installs research hardware inside the Destiny laboratory module’s Microgravity Science Glovebox. The equipment supports the Fluid Particles experiment, which helps researchers understand how particles in a liquid interface come together to form larger structures or clusters in microgravity. Results could advance fire suppression, lunar dust control, and plant growth in space. Earth benefits may include insights into pollen behavior, algae blooms, plastic pollution, and sea salt transfer during storms.
