Russia says it would be ready to extend spaceflight sharing deal with U.S.

The deal is an unusual example of Moscow and Washington still cooperating at a time when ties are at a post-Cold War low due to tensions.

Russia would be ready to extend a deal with the United States to share flights to the International Space Station beyond 2024 if the first three flights are successful, the executive director of Russia's space agency said on Friday.

NASA and Russian space agency Roscosmos signed an agreement in July allowing Russian cosmonauts to fly on U.S.-made spacecraft in exchange for American astronauts being able to ride on Russia's Soyuz spacecraft.

Russia's RIA news agency reported at the time that the agreement envisaged six flights in total between 2022 and 2024, with each country getting three flights each on the other's spacecraft.

"The agreement has now been signed for the first three flights," said Sergei Krikalev, executive director of Roscosmos.

"If the implementation of this agreement will be positive then we will certainly continue it."

The deal is an unusual example of Moscow and Washington still cooperating at a time when ties are at a post-Cold War low due to tensions over what Russia calls its "special military operation" in Ukraine, a conflict the West calls an unprovoked war of aggression.

Russia has cast doubt over space cooperation in other areas and spoken of pulling out of the International Space Station after 2024 to develop its own orbital station. It has so far sent mixed messages however, suggesting that date could significantly slip.
