Russian cosmonauts Oleg Kononenko and Nikolai Chub have set a new record for the longest single mission aboard the International Space Station (ISS). In a statement, Russia’s state space corporation Roscosmos said that Kononenko and Chub broke the previous record for the longest continuous stay in space, which was set by cosmonauts Sergei Prokopyev, Dmitry Petelin, and NASA astronaut Francisco Rubio. The three set the previous record last year by spending 370 days aboard the International Space Station. Kononenko and Chub are expected to return to Earth on the Soyuz MS-25 spacecraft on September 23, 2024, after spending a record 374 days in space.
