Umberto Guidoni made history in 2001 by becoming the first European to set foot aboard the International Space Station. His trajectory from astrophysics student at Sapienza University of Rome to orbiting the planet with NASA underscores the transition of European participation in space exploration during the late twentieth and early twenty-first centuries.
Scientific Training and Orbital Missions
Born in 1954 in Rome, Guidoni earned his doctorate in astrophysics in 1978. His professional career began within the Italian Space Agency and the European Space Agency, focusing on the Tethered Satellite System. He served as an alternate payload specialist for the STS-46 mission before participating in his inaugural spaceflight aboard the Space Shuttle Columbia in 1996. Five years later, he flew on the STS-100 mission, which delivered the Raffaello Multi-Purpose Logistics Module and the Canadian robotic arm to the International Space Station.

Guidoni transitioned from space exploration to governance in 2004 following his election to the European Parliament as a member of the Group of the European United Left. Based in Brussels and Strasbourg, he served on committees dedicated to budgetary control, industry, research, and energy. During this period, he acted as rapporteur for the Seventh Framework Programme and proposed amendments aimed at safeguarding press freedom during intellectual property enforcement debates. He concluded his parliamentary term in 2009.
Science Communication and Literature
Since retiring from active flight status, Guidoni has focused on popularizing scientific concepts. In 2007, he hosted a Radio Rai 2 program titled From the Sputnik to the Shuttle, documenting the history of space travel. He expanded this work into literature, authoring books such as From the Earth to the Moon and various children's titles, including Martino on Mars and Guida per Giovani Astronauti. His contributions have been recognized with honors including the NASA Exceptional Service Medal and the Order of Merit of the Italian Republic.
