America's first crewed spaceship in decade splashes down off Florida
The SpaceX Crew Dragon Endeavour's four main parachutes gently floated down after the vessel landed off the coast of Pensacola. Pilot Doug Hurley, one of the two astronauts on board, said: "It's truly our honor and privilege" as radio communications became choppy and cut out.
America's first crewed spaceship to achieve orbit since the Space Shuttle era splashed down safely in the Gulf of Mexico on Sunday.
The SpaceX Crew Dragon Endeavour's four main parachutes gently floated down after the vessel landed off the coast of Pensacola at 2:48 pm (1848 GMT).
Pilot Doug Hurley, one of the two astronauts on board, said: "It's truly our honor and privilege" as radio communications became choppy and cut out.
A recovery boat speeded to collect Hurley and commander Bob Behnken, who spent two months on board the International Space Station.
The successful mission demonstrated that the United States once again has the capacity to send its astronauts to space and bring them back.
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 this purpose since the last Space Shuttle flew in 2011.
Tropical Storm Isaias, which had scuppered Endeavour's original landing site in the Atlantic, was nearing Florida's east coast Sunday morning, hundreds of miles away.
The mission is also a major win for Elon 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 badly floundered.
The Crew Dragon capsule performed several precise procedures in order to return home safely.
At 1:51 pm (1751 GMT), it jettisoned its "trunk" that contains its power, heat and other systems, which will re-enter the Earth's atmosphere and burn up.
Endeavour then fired its thrusters to maneuver itself into the proper orbit and trajectory for splashdown.
At 2:32 pm (1832 GMT) re-entered the atmosphere at a speed of around 17,500 mph (28,000 kph).
The ship's heat shield needed to withstand temperatures of 3,500 degrees Fahrenheit (1900 degrees Celsius), which caused a communications blackout for a few minutes.
Endeavour then deployed two sets of parachutes on its descent, bringing its speed down to a mere 15 mph (24 kph) as it hits the water.
Over the next few minutes, two astronauts will be brought on board a recovery ship for a medical checkup before being taken ashore.
The SpaceX Crew Dragon spacecraft set off from the ISS Saturday evening.
Footage showed the capsule drifting slowly away from the ISS in the darkness of space, ending a two month stay for the crewmates.
During a farewell ceremony on the station, Behnken said that "the hardest part was getting us launched. But the most important part is bringing us home."
Addressing his son and Hurley's son, he held up a toy dinosaur that the children chose to send on the mission and said: "Tremor The Apatosaurus is headed home soon and he'll be with your dads."
Behnken and Hurley's return marks only the beginning for the Crew Dragon as SpaceX and NASA look ahead to future missions.
Endeavor will be brought back to the SpaceX Dragon Lair in Florida where it will undergo a six-weeks-long inspection process, as teams pore over its data and performance in order to certify the vessel as worthy of future low-Earth orbit missions.
The next mission -- dubbed "Crew-1" -- will involve a four member team: commander Michael Hopkins, pilot Victor Glover, and mission specialist Shannon Walker of NASA, along with Japan Aerospace Exploration Agency mission specialist Soichi Noguchi.
Take-off is set for late September and the crew are due to spend six months on the space station.
