Russia sticking with ISS for now

·2-min read

Russian space officials have told their US counterparts Moscow expects to remain a part of the International Space Station at least until their own outpost in orbit is completed, a senior NASA official says.

Yuri Borisov, the newly appointed director-general of Russia's space agency Roscosmos, surprised NASA on Tuesday by announcing Moscow intended to end the longstanding space station partnership "after 2024".

Kathy Lueders, NASA's space operations chief, said in an interview Russian officials later on Tuesday told the US space agency Roscosmos would remain in the partnership as Russia works to get its planned orbital outpost, named ROSS, up and running.

"We're not getting any indication at any working level that anything's changed," Lueders told Reuters on Wednesday, adding that NASA's relations with Roscosmos remain "business as usual".

The space station, a science laboratory spanning the size of a football field and orbiting some 400 kilometres above earth, has been continuously occupied for more than two decades under a US-Russian led partnership that also includes Canada, Japan and 11 European countries.

It offers one of the last holdouts of co-operation between Washington and Moscow, though its fate has been called into question since Russia invaded Ukraine in February.

A formal agreement to extend Russia's participation beyond 2024 has not yet been made.

NASA, Russia and the station's other partners plan to discuss the prospect of extending each other's presence on the laboratory to 2030 during a periodic meeting on Friday of the board that oversees the station's management, Lueders said.

Roscosmos published on its website on Wednesday an interview with Vladimir Solovyov, the flight director for the space station's Russian segment, who was quoted as saying Russia must remain on the station until ROSS is operating.

"We, of course, need to continue operating the ISS until we create a more or less tangible backlog for ROSS," Solovyov said.

"We must take into account that if we stop manned flights for several years, then it will be very difficult to restore what has been achieved."

The American and Russian segments of the space station were deliberately built to be intertwined and technically interdependent.
