NASA and Russia will keep launching each other's astronauts to ISS until 2025: report

NASA and Russia have agreed to keep launching American astronauts and Russian cosmonauts on each other's spacecraft, media reports suggest.

Roscosmos announced both it and NASA will continue the International Space Station launches with each other's crew members through at least 2025, "to maintain the reliability of the ISS as a whole," according to multiple reports including the Moscow Times.

A NASA spokesperson confirmed the agreement in an email to Space.com. "NASA and Roscosmos have amended the integrated crew agreement to allow for a second set of integrated crew missions in 2024 and one set of integrated crew missions in 2025," the spokesperson wrote. "For continued safe operations of the space station, the integrated crew agreement helps ensure that each crewed spacecraft docked to the station includes an integrated crew with trained crew members in both the Russian and U.S. Operating Segment systems."

NASA and Roscosmos have an existing agreement to launch crew members on each other's spacecraft, to allow for independent launch access for both nations and backup in case of trouble. Right now the manifest includes SpaceX Dragon for NASA missions, and Soyuz for Russia. (When Boeing Starliner is ready, presumably it will be included too for U.S. missions.)

The ISS is manifested to last until at least 2030, as most of the international coalition has agreed to stick with it. Russia will remain until 2028 or so, based on the most recent reports; the country is working on a different set of space plans in the future.

Though NASA and Russia are the chief ISS partners alongside the European Space Agency, Japan and Canada, relations changed in 2022 when Russia invaded Ukraine to the condemnation of most of the world. Most space partnerships were severed with Russia aside from the ISS, which remains for space policy reasons.

Russia and NASA operate different segments of the space station with different operational responsibilities. They also send up cargo ships for resupply missions and interface with the crew in independent mission controls. 

Since 2022, Russia has teamed up with China to launch a moon-facing alliance. NASA also has its own group, under the Artemis Accords, a coalition of 30-plus nations that themselves promise peaceful space exploration norms with a subset of countries also participating in moon exploration.

The Artemis Accords aim to put astronauts on the moon no earlier than 2025 with Artemis 3, and have already launched Artemis 1 (uncrewed) in 2022 around the moon. Artemis 2, with four astronauts on board, should launch around the moon in 2024 or so.
