Nasa astronauts will go back to travelling on Russian rockets while Russian cosmonauts will catch lifts to the International Space Station with US company SpaceX, it has been announced.
The agreement ensures that the space station will always have at least one American and Russian on board to keep both sides of the orbiting outpost running smoothly, according to Nasa and Russian officials.
The deal had long been in the works and was finalised despite tensions over Moscow’s war in Ukraine, a sign of continuing Russia-US cooperation in space.
US astronaut Frank Rubio will launch to the space station from Kazakhstan with two Russians in September.
In dust we trust 🌫
After launching this evening, our cargo resupply mission en-route to the International @Space_Station is carrying a @NASAEarth experiment that will help us understand the effect of dust plumes on our climate: https://t.co/xjcph6iMz2 pic.twitter.com/tLeRvuqivpAdvertisement— NASA (@NASA) July 15, 2022
The same month, Russian cosmonaut Anna Kikina will join two Americans and one Japanese aboard a SpaceX rocket flying from Florida. Another crew swap will occur next spring.
No money will exchange hands under the agreement, according to Nasa.
Nasa astronauts routinely launched on Russian Soyuz rockets — for tens of millions of dollars apiece — until SpaceX started flying station crews from Nasa’s Kennedy Space Centre in 2020.
Russian cosmonauts rode to the space station on Nasa’s shuttles back in the early 2000s. Before that, during the 1990s, astronauts and cosmonauts took turns flying on each other’s spacecraft to and from Russia’s Mir station.
Friday’s news came just hours after the chief of the Russian space agency, Dmitry Rogozin, was replaced by President Vladimir Putin, although the move did not appear to have any connection to the crew swap.
Mr Rogozin was expected to be given a new post.
NASA said the agreement will “ensure continued safe operations” of the space station and protect those living on board. Seven people are up there right now: three Americans and one Italian who flew up with SpaceX and three Russians who arrived in a Soyuz.
