The Roscosmos is the second Russian-made vessel to spring a leak since December, when the vessel that carried U.S. astronaut Frank Rubio and Russian cosmonauts Sergey Prokopyev and Dmitri Petelin also began to leak.
The U.S. and Russian space programs have continued to work together in maintaining the ISS despite Russia's war in Ukraine.
