Video interview (Italian) with astronaut Walter Villadei about his path to becoming an astronaut, training in Russia and the U.S., a suborbital flight and an orbital mission. Villadei recounts long preparation (training detachment to Russia beginning 2011), a Virgin Galactic suborbital flight (~95 km peak) and piloting Axiom 3 to the ISS (2024). He describes differences between Russian and American training, life aboard the ISS (microgravity sensations, daily schedule in GMT, sleep arrangements, food including a pasta experiment), technologies and experiments on board (Cupola, Columbus module, microscopes, combustion chamber, radiation detectors, debris-detection software, cell biology and material tests, ultrasound diagnostics), operational details (Crew Dragon rendezvous timing: ~37 hours to reach ISS, ~48 hours return), and perspectives on future commercial stations, lunar and Mars exploration. Emphasis on teamwork and Italy's industrial/scientific contributions (Columbus, Axiom partnership, modules built in Turin).
