NASA has made an official announcement regarding the roster for Crew 9, currently scheduled to fly to the International Space Station aboard a SpaceX Crew Dragon no earlier than September 24.

In a press release issued August 30, the agency said, “NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov will launch no earlier than Tuesday, Sept. 24, on the agency’s SpaceX Crew-9 mission to the International Space Station. NASA astronauts Zena Cardman and Stephanie Wilson, previously announced as crewmates, are eligible for reassignment on a future mission.”

They added that Hague and Gorbunov would fly to the space station as commanders and pilots on a two-crew member flight aboard a SpaceX Dragon. These changes were made to create room aboard Crew Dragon for Boeing Starliner Crewed Flight Test astronauts Butch Wilmore and Suni Williams, whose spacecraft will return to Earth on September 6 without the two aboard.

“I am deeply proud of our entire crew,” said Cardman said in the NASA press release, “and I am confident Nick and Alex will step into their roles with excellence. All four of us remain dedicated to the success of this mission, and Stephanie and I look forward to flying when the time is right.” 

Wilson added, “I know Nick and Alex will do a great job with their work aboard the International Space Station as part of Expedition 72.”

NASA Chief Astronaut Joe Acabo said, “While we’ve changed crew before for a variety of reasons, downsizing crew for this flight was another tough decision to adjust to given that the crew has trained as a crew of four.”

NASA says it will share the reassignment details for Cardman and Wilson when they become available.
