NASA astronauts Zena Cardman and Stephanie Wilson were intending to get a lift to the Internaitonal Space Station on board a SpaceX Crew Dragon spacecraft over the weekend. But thanks to Boeing's disastrous crewed test flight of its issues-laden Starliner spacecraft,

Starliner was originally meant to allow Boeing to carry crews back and forth to the ISS for NASA, making them a rival to SpaceX, so it’s a bitter irony for Boeing that its flight test crew will be coming home in a SpaceX Crew Dragon capsule.

Two woman astronauts had to stay behind to make space for their stranded Starliner colleagues, Butch Wilmore and Suni Williams.

The U.S. Federal Aviation Administration is requiring an investigation of the anomaly a SpaceX Falcon 9 rocket experienced during the Crew-9 astronaut launch on Sept. 28.

The Dragon capsule has two empty seats for Butch Wilmore and Suni Williams, who were only meant to be on the ISS for eight days, but were forced to remain there because of a fault discovered during the flight.
