NASA administrator congratulates Greece on first astronaut mission to ISS

On September 10, 2026, NASA Administrator Jared Isaacman publicly congratulated Greece on its upcoming first private astronaut mission to the International Space Station (ISS). The announcement follows a formal agreement signed between the European Space Agency (ESA), acting on behalf of Greece, and the American space company Vast.

The mission will feature Greek astronaut Adrianos Golemis, who is set to participate in a private crewed flight to the orbital laboratory. This initiative is part of Greece's broader participation in the Artemis Accords, which aim to foster international cooperation in space exploration. Isaacman emphasized that the mission is a significant step in Greece’s role in shaping the future of global space exploration and contributing to a sustainable low-Earth orbit (LEO) economy.

While the specific launch dates were not provided in the initial reports, the agreement between ESA and Vast marks a milestone for the Greek space program. By participating in this private sector mission, Greece continues to strengthen its involvement in international space initiatives and its strategic partnership with global aerospace entities.
