iss074e0603699 (May 20, 2026) --- NASA astronauts Jessica Meir and Jack Hathaway, both Expedition 74 flight engineers, work together to process stem cell samples aboard the International Space Station’s Kibo laboratory module. Meir nourished the stem cells inside Kibo's Life Science Glovebox after Hathaway retrieved them from a science freezer, thawed them, and handed them over for treatment. The research may lead to the development of space-designed therapies to treat cancer and blood conditions. Credit: NASA
