Previously unannounced repair work to stop new leaks onboard the International Space Station temporarily caused NASA to send all four members of the agency's SpaceX Crew-12 mission as well as NASA astronaut Chris Williams into the Dragon capsule, Freedom, on Friday.
Cracks and leaks have popped up within the Russian segment of the space station within the Zvezda service module transfer tunnel, called the PrK, off and on over the past six years or so.
However, NASA said the discovery of "new leaks" caused the Russian space agency Roscosmos "to proceed with a more extensive repair operation on Friday, June 5.
