Double science!

Onboard the International Space Station for the εpsilon mission, ESA astronaut Sophie Adenot is ready for a PhysioTool session, while NASA astronaut Jessica Meir wears the T‑Mini headband during her daily activities.

PhysioTool, an experiment developed by the French space agency CNES, monitors how the human body and mind adapt to life in weightlessness, where the constant pull of gravity disappears.

ESA’s Thermo-Mini experiment, or T‑Mini, examines how the body regulates its core temperature during spaceflight.
