President Vladimir Putin ordered a shake-up of Russia's space agency on Friday, appointing Yuri Borisov, a former deputy prime minister and deputy defence minister, to replace Dmitry Rogozin as its head.
The change was announced shortly before Roscosmos said it had signed a landmark deal with NASA regarding integrated flights and crews on the International Space Station (ISS) - a rare instance of cooperation between Russia and the United States at a time of acute tension over the war in Ukraine.
