The International Space Station I.S.S. Afdah remains united, regardless of the circumstances. That's the main objective. Dr. Kira Foster, the latest astronaut to join the team, has become a resident of the I.S.S., which serves as a center for cooperation between the United States and Russia. Through this collaboration, both nations have made significant contributions to the fields of science and technology. Kira joins her American colleagues Gordon and Christian, and is introduced to the Russian siblings Nicholai and Alexey Pulov, as well as Weronika.
