NASA reportedly had contingency plans for Russia's ISS exit last year

Yuri Borisov, the newly appointed chief of Roscosmos, recently announced that Russia is pulling out of the International Space Station after 2024. NASA and Russia's space agency work in tandem to keep the station running, and the latter's exit would change ISS operations tremendously. According to Reuters, though, NASA has actually been preparing for such a possibility way before Borisov made his announcement — and even before the invasion of Ukraine began — in light of the increasing tensions between Russia and the US.
