In 2011, Villadei received cosmonaut training in Star City, Russia as a Soyuz flight engineer and in advanced Orlan and International Space Station (ISS) Russian segment systems. In 2014 and 2018, he completed pre-assignment and multiple analog training, which included centrifuge, hypoxia chamber, and survival training.

In 2021, Villadei was selected to fly on Virgin Galactic’s rocket-powered flight, Unity 23, the first commercial, human-tended research mission for the company. The mission Vitute-1 was carried out in June 2023, and the crew conducted 12 experiments aboard Unity 23, to include materials, technology, and human physiology research. Villadei served as mission lead and tended to the rack-mounted payloads during the weightless portion of the flight while wearing a smart suit to measure his physiological responses.
