The two nations' space agencies have not yet decided on any concrete date but are working "as a team," Ken Bowersox has told TASS

The Russian and American space agencies are developing a plan for de-orbiting the International Space Station (ISS), NASA's associate administrator for Space Operations Mission Directorate, Ken Bowersox, has told TASS.

Launched back in 1998, the project has seen Russia, the US, Canada, Japan, as well as multiple European nations join forces to keep the station operational.

Speaking to TASS on Wednesday, Bowersox said that "we work together to come up with a detailed plan for how we will actually end station." 

"There is always a chance that we could go longer. There is always a chance we could go shorter if something bad were to happen on station," he added, noting that NASA specialists are cooperating with their colleagues from Russia and other partner nations "as a team." 

According to Bowersox, the topic of ISS operations is discussed by Moscow and Washington on a regular basis.

On Monday, NASA's associate administrator for Space Operations Mission Directorate met with Roscosmos CEO Dmitry Bakanov at the Russian-operated Baikonur Cosmodrome in Kazakhstan.

According to a Roscosmos press release, the two officials reviewed several initiatives, including preparations for future launches from the new Baiterek Rocket Complex - a joint Russian-Kazakh project designed to support the launch of the new Soyuz-5 rocket.

The discussions came ahead of the 50th anniversary of the Apollo-Soyuz Test Project - the first manned spaceflight jointly carried out by the US and Soviet Union in 1975.

Despite the Ukraine conflict and the drastic decline in bilateral relations, space cooperation between the US and Russia has been among the few realms that have remained largely unaffected. NASA and Roscosmos recently extended their cross-flight agreement to the ISS through 2026, and have collaborated continuously on station-related missions over the past three years.
