SpaceX capsule docks at ISS to shuttle stuck Boeing Starliner crew home

• Theirs was the first crewed Starliner test flight. But their return trip, scheduled for February, will be aboard a SpaceX Dragon spacecraft.

Catch up quick: Wilmore and Williams have been stranded in an extended layover on the ISS since they docked June 6 and have been living and working alongside the existing crew there.

• In a setback for Boeing's space program, NASA announced in August that SpaceX would shuttle the astronauts back.
• "The uncertainty and lack of expert concurrence does not meet the agency's safety and performance requirements for human spaceflight," the agency stated, citing helium leaks and issues with reaction control thrusters on Starliner.
• SpaceX's Dragon spacecraft has completed over 40 visits to the ISS.
• Starliner returned from space earlier this month — without a crew.

Flashback: Boeing's Starliner was star-crossed even before the inaugural crewed mission earlier this year.

Driving the news: The SpaceX mission launched Saturday from Cape Canaveral and docked at the ISS Sunday.

• "I just want to say welcome to our new compadres," Williams said after astronauts Nick Hague and Aleksandr Gorbunov arrived.
• Their arrival also means four astronauts who have been there since March can now also return to Earth in their own capsule after their stay was extended because of the Starliner incident, the AP reported.
