NASA astronaut Jessica Watkins works in the Kibo laboratory module’s Life Science Glovebox

iss075e0189758 (Oct. 9, 2026) --- NASA astronaut and Expedition 75 flight engineer Jessica Watkins works in the Kibo laboratory module's Life Science Glovebox, safely mixing living cell samples with a bioink and then filling a special cartridge with the cell‑ink mixture. The advanced research operations were part of the InSPA‑Auxilium Bioprinter‑Cell Printing investigation, which explores 3D bioprinting cartilage tissue in microgravity of higher quality than that produced on Earth. Results may advance the ability to biomanufacture cartilage, benefiting patients on Earth and crew members on long‑duration space missions.
