A third astronaut has been announced to join Thomas Pesquet on a future space mission: Adrianos Golemis, a Greek trainee flight doctor. Golemis will travel to the International Space Station (ISS) as early as the summer of 2027, making him the first Greek astronaut in history. The announcement was made during the Space Summit in Paris on September 9, 2026, in the presence of French President Emmanuel Macron and Greek Prime Minister Kyriakos Mitsotakis. The mission, organized by the American company Vast, is expected to last about two weeks. Pesquet, Golemis, and Czech astronaut Aleš Svoboda will take part, with Pesquet leading the mission, Svoboda acting as pilot, and Golemis serving as a mission specialist. Adrianos Golemis has already begun training as a reserve astronaut and spent a full year at the Concordia research station in Antarctica. There, he studied how the human body functions under extreme cold and isolation. The mission, named PAM-1, is primarily meant to prepare for Vast's future space station, Haven, which is planned to be launched into orbit in the coming years. Haven is intended to eventually replace the ISS, which is expected to be retired and deorbited in the 2030s. There is still one open spot on the mission, which is expected to be announced soon. The European Space Agency and Vast have welcomed the upcoming mission, which will be the company's first on the ISS, following earlier private missions by Axiom Space. This marks the first time Greece, a long-time partner in the space sector, is involved in such a mission. However, the initiative has faced criticism. Employees of CNES, France's space agency, have expressed concerns and are demonstrating at the sidelines of the summit. They are protesting against the lack of salary increases and budget constraints. They also criticize the contract with the American startup Vast, which was announced as a surprise and is worth several tens of millions of euros. They argue that this contract supports the business model of space tourism at the expense of ecological concerns, scientific research, and French industrial independence. Additionally, they question the scientific value of such a short mission, arguing that two weeks are not enough time to conduct meaningful experiments. Critics also point out that Europe, which often calls for greater space sovereignty and autonomy in human spaceflight, is now sending its astronauts to foreign companies.
