NASA astronaut Mike Fincke displays protein crystal research hardware

iss073e0548503 (Aug. 28, 2025) --- NASA astronaut and Expedtion 73 Flight Engineer Mike Fincke displays the Nanoracks' Nanolab Space Liintech research hardware inside the International Space Station's cupola while orbiting 262 miles above a cloudy United States. Nanolab Space LiinTech tests a platform that uses optical technology to monitor the process of producing protein crystals in microgravity. This investigation could lead to the development of technology for crystallizing proteins in microgravity to produce pharmaceuticals for use in space and Earth.
