Russia tells NASA it will remain with International Space Station until at least 2028

Russian space officials told their U.S. counterparts that Moscow expects to remain on the International Space Station (ISS) at least until their own outpost in orbit is built in 2028, NASA's space operations chief told Reuters.

The assurance on Tuesday from Russia came after the newly appointed head of its space agency, Roscosmos, surprised NASA earlier in the day by announcing that Moscow intended to end more than two decades of partnership on the space station "after 2024."

"We're not getting any indication at any working level that anything's changed," Kathy Lueders, NASA's space operations chief, told Reuters on Wednesday, adding the U.S. space agency's relations with Roscosmos remained "business as usual."

Any ISS partner must give a year's notice that they are withdrawing from the international agreement.

Russia's space program has a long and storied history. As the Soviet Union, it launched the first satellite, Sputnik, in 1957; launched the first human into space, Yuri Gagarin in 1961; launched the first woman into space, Valentina Tereshkova, in 1963; and both performed the first spacewalk and built the first space station. Their Soyuz rockets, which take their cosmonauts to the ISS, are workhorses designed from the end of the Cold War era.

However, since the fall of the Soviet Union, Roscosmos has faced many challenges, both financial and political. Most recently, it has been accused of corruption.

Over the years, the then-head of Roscosmos, Dmitry Rogozin, has made outlandish threats and suggestions to NASA. When the war in Ukraine began, he threatened to abandon American astronauts aboard the ISS — complete with a video — got into a heated Twitter exchange with former NASA astronaut Scott Kelly, and told NASA it would have to use broomsticks to get to the station.

Russia has also focused more on the military uses of space, and last November carried out an anti-satellite test that produced more than 1,500 pieces of trackable debris. The act was widely condemned by the space community and other countries.

Russians continue to work and live aboard the ISS and, in September, cosmonaut Anna Kikina will fly aboard a SpaceX rocket as a mission specialist headed to the station.

NASA has plans to continue using the ISS until at least 2030.
