Russia's "Nauka" Multipurpose Laboratory Module is pictured shortly after docking to the Zvezda service module's Earth-facing port on the International Space Station.

NASA directed five astronauts to board a docked SpaceX Dragon spacecraft as Roscosmos cosmonauts attempt to address a leak problem on the International Space Station, NASA Press Secretary Bethany Stevens said in a post on X Friday (US time).

The cracks and leaks on a portion of the space station operated by Russia, located in a transfer tunnel between a module called Zvezda and a docking hatch, have been a known concern for some time. But the NASA statement suggested the situation had potentially worsened.
