Weather conditions off the Florida coast, where astronauts Butch Wilmore and Suni Williams will land with the two members of a mission known as Crew-9, prompted NASA and SpaceX to move up the mission's return date.

NASA astronauts Suni Williams and Butch Wilmore are back on Earth. NASA and SpaceX's Crew-9 mission successfully splashed down into the Gulf of America, off the Florida Coast on Tuesday evening. It comes nearly 10 months after Williams and Wilmore launched to the International Space Station aboard Boeing's Starliner spacecraft.
