America's first crewed spaceship to fly to the International Space Station in nearly a decade returned safely to Earth on Sunday, splashing down in the Gulf of Mexico.

The mission, carried out jointly by NASA and the private company SpaceX, demonstrated that the United States has the capacity once more to send its astronauts to space and bring them back.

The SpaceX Crew Dragon Endeavour splashed into the water off Pensacola, Florida at 2:48 pm (1848 GMT), trailed by its four main parachutes.

It was the first water landing for a crewed US spaceship since the 1975 Apollo-Soyuz mission.

"It's truly our honor and privilege," said pilot Doug Hurley, who was joined on the mission by commander Bob Behnken.

"On behalf of the NASA and SpaceX teams, welcome back to planet Earth and thanks for flying SpaceX," replied SpaceX's Mike Heiman, to laughter in the control room.

A flotilla of civilian boats swarmed the landing zone as a recovery ship sped to the scorched capsule and hoisted it aboard with its crane.

The Coast Guard said it had warned people to stay away from the capsule but "numerous boaters" ignored the requests.

The "capsule was in the water for a good period of time," said NASA administrator Jim Bridenstine, "the boats just made a beeline for it." 

The hatch opening was delayed as a team worked to stop a potentially dangerous leak of rocket fuel vapor. 

"What's not common is having passers-by approach the vehicle at close range with nitrogen-tetroxide in the atmosphere... We need to make sure we’re warning people not to get close to the spacecraft in the future," Bridenstine said.

Around an hour after splashdown, the astronauts exited the capsule and headed for shore on a helicopter.

They were reunited with their families in Houston, where they walked off a plane -- in apparently good physical shape and upbeat spirits -- at a military base.

Addressing a socially distanced welcome ceremony in a hangar, Behnken, a veteran of the Space Shuttle program, praised the SpaceX team behind the successful mission.

"There's something special about having that capability to launch and bring your own astronauts home," he said.

A visibly excited SpaceX founder Elon Musk said the mission heralded a new era.

"We're going to go to the Moon, we're going to have a base on the Moon; we're going to Mars," he said.

"I'm not very religious but I prayed for this one."

- Space autonomy -

President Donald Trump -- who had travelled to Florida for the capsule's launch two months ago -- hailed its safe return.

"Thank you to all!" he tweeted. "Great to have NASA Astronauts return to Earth after very successful two month mission." 

The United States has had to rely on Russia for rides to space since the last Space Shuttle flew in 2011.

The mission is also a huge win for Musk's SpaceX, which was founded in only 2002 but has leap-frogged its way past Boeing, its main competitor in the commercial space race.

The US has paid the two companies a total of about $7 billion for their "space taxi" contracts, though aerospace giant Boeing's efforts have floundered.

- Atmospheric re-entry - 

The Crew Dragon capsule performed several precisely choreographed sequences in order to return home safely.

First, it jettisoned its "trunk" that contains its power, heat and other systems, which burned up in the atmosphere.

It then fired its thrusters to maneuver into the proper orbit and trajectory for splashdown. 

As it re-entered the atmosphere at a speed of around 17,500 mph (28,000 kph), it experienced temperatures of 3,500 degrees Fahrenheit (1900 degrees Celsius).

It deployed two sets of parachutes on its descent, bringing its speed down to a mere 15 mph as it hit the Gulf of Mexico.

Endeavour will now undergo a six-week inspection to certify the vessel as worthy of future low-Earth orbit missions.

The next mission -- dubbed "Crew-1" -- will involve a team of four: three NASA astronauts along with Japan Aerospace Exploration Agency mission specialist Soichi Noguchi.

Launch is set for late September, and the crew is due to spend six months on the space station.
