NASA astronaut Butch Wilmore has officially retired, just months after returning from an unexpectedly extended mission aboard the malfunctioning Boeing Starliner.

Stuck in space no more, NASA astronauts Butch Wilmore and Suni Williams returned to Earth on Tuesday, hitching a different ride home to close out a saga that began with a bungled test flight more than nine months ago.

Two NASA astronauts stranded on the International Space Station (ISS) since last June have begun their journey back to Earth aboard a SpaceX Dragon flight.

The SpaceX Crew Dragon spacecraft successfully relocated from the forward to the side port of the Harmony module of the International Space Station (ISS).
