NASA astronaut Mike Fincke gives a thumbs-up in front of the Microgravity Science Glovebox

iss073e0917010 (Oct. 21, 2025) --- NASA astronaut and Expedition 73 Flight Engineer Mike Fincke gives a thumbs-up in front of the Microgravity Science Glovebox (MSG) inside the International Space Station's Destiny laboratory module. Fincke had just completed research operations for 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.
