ESA astronaut Sophie Adenot launched to the International Space Station on 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.

Launch: Friday, 13 February 2026 at 10:15 GMT/11:15 CET (05:15 ET) from Florida, USA

Docking: Saturday, 14 February at 20:15 GMT/21:15 CET

Spacecraft: SpaceX Dragon 

Expeditions: 74/75
