ESA astronaut Sophie Adenot will launch to the International Space Station no earlier than 13 February 2026 for a mission called εpsilon.
The mission name embodies the essence of small, yet impactful, contributions. In mathematics, ε denotes a small quantity, much like an astronaut's role in the vastness of spaceflight. In astronomy, it represents the fifth-brightest star in a constellation.
Sophie will fly to space with her Crew-12 crewmates on a SpaceX Dragon launching from Florida, USA. The crew of four includes NASA astronauts Jessica Meir and Jack Hathaway, as well as Roscosmos cosmonaut Andrei Fedyaev.
