Summary

Description	English: Expedition 67 Flight Engineer and NASA astronaut Jessica Watkins sets up cell samples for viewing in a microscope for the Immunosenescence space biology study. The investigation studies the immunological aging of cells that takes place in microgravity to learn how to keep astronauts healthy on long term missions and treat immunity conditions on Earth.
