NASA says it has not received official word from Russia on plans to stop working on the International Space Station (ISS) after 2024.
The newly appointed head of Russian space agency Roscosmos, Yuri Borisov, made headlines Tuesday when he told Russian President Vladimir Putin that the agency would cease operations on the ISS after 2024.
NASA’s Robyn Gatens, who leads the agency’s ISS operations, told Reuters she “just saw that” on Tuesday morning and that there was “nothing official yet” to confirm Roscosmos was pulling out.
Gatens, speaking at a conference in Washington, D.C., told the news outlet that international agreements required Russia to notify them of any such decision.
The previous head of Russia’s space agency, Dmitry Rogozin, said in May that Russia would pull out from the ISS in response to international sanctions placed on Moscow for its invasion of Ukraine.
In December, NASA announced plans to extend operations for the orbiting space science laboratory through at least 2030, along with partners including Russia.
“As more and more nations are active in space, it’s more important than ever that the United States continues to lead the world in growing international alliances and modeling rules and norms for the peaceful and responsible use of space,” NASA Administrator Bill Nelson said at the time.
The ISS, first initiated in 1998, is a joint operation from Russia, the U.S., Europe, Japan and Canada. Russia is a crucial partner because it supplies thrusters that keep the space station above a certain altitude, while the U.S. gives the ISS power through a grid.
Tensions between Russia and the U.S. have escalated after Putin launched an invasion of Ukraine in late February.
