SpaceX was already tasked with returning NASA astronauts Butch Wilmore and Suni Williams as part of the Crew-9 mission. That departure was delayed by NASA due to unresolved issues with the fifth Crew Dragon capsule that will launch the Crew-10 flight.

Crew members on the International Space Station over the weekend continued trying to pinpoint the location of a small air leak in the research outpost’s Russian Zvezda service module, one of the oldest sections of the orbiting laboratory.

A SpaceX Dragon supply ship arrived at the International Space Station Saturday carrying a new docking mechanism, a spacesuit for future spacewalks, and a 3D bioprinter to test the feasibility of manufacturing human tissue in microgravity.
