US astronauts Bob Behnken and Doug Hurley will be returning from their voyage to the International Space Station today.
Crew Dragon “Endeavor” decoupled from the orbital station at 7:35pm ET.
Mr Hurley told the remaining US station crew member Chris Cassidy: “It’s been a great two months, and we appreciate all you’ve done as a crew to help us prove out Dragon on its maiden flight.”
Mr Benken said ahead of his exit from the station: “The hardest part was getting us launched, but the most important part is bringing us home.”

Will Hurricane Isaias affect Crew Dragon landing?
Tropical Storm Isaias is not expected to affect the return home on Sunday of SpaceX’s new Crew Dragon.
Prior to approving Pensacola as a safe splashdown site, Nasa and SpaceX were considering seven sites around the state’s peninsula.
Zebulon Scoville, NASA’s flight director, wrote on Twitter on Saturday morning: “So not intuitive, but Isaias may actually help make nice weather on landing a few hundred miles west.”
NASA and SpaceX are monitoring Tropical Storm Isaias’ progress.
According to the National Hurricane Center’s (NHC) 5am EDT (10am BST) advisory, Tropical Storm Isaias is currently churning with maximum sustained wind speeds of 65mph.
At the time the advisory was issued, the storm was located about 45 miles east-northeast of Fort Lauderdale, and about 45 miles southeast of West Palm Beach in Florida.
The NHC has issued a number of hurricane warnings and storm surge watches, in addition to tropical storm warnings and watches.
