Back. This Sunday and after two months in space, the two American astronauts returned safely to Earth aboard a SpaceX capsule, a successful end of mission which paves the way for regular manned flights with this new space vehicle. for NASA.
In less than an hour, aboard SpaceX's Dragon, Bob Behnken and Doug Hurley went from a speed of 28,000 km / h in orbit to a speed of 24 km / h at the time of the landing, four large parachutes having opened as expected after the scorching re-entry. They landed off Pensacola in the Gulf of Mexico, a site chosen to avoid a tropical storm in the area.
"Welcome to Earth"
“Welcome to Earth, and thank you for flying on SpaceX,” the flight director announced to the astronauts, who are fine and responded. “It was an honor and a privilege,” said Doug Hurley.
The successful round trip to the International Space Station (ISS) puts an end to the Russian monopoly on access to the ISS since the Americans parked their space shuttles in July 2011. NASA will use the Dragon capsule from the order of twice a year to send four astronauts at a time, including non-Americans, a Japanese and the European Thomas Pesquet being planned for the next missions.
The mission may seem like a modest step in space exploration: "Bob" and "Doug" did not go to the moon or to Mars, only to the old space station, 400 km from Earth, where Russians and Americans and others have been coming and going since 1998.
NASA, however, sees it as a "revolution", because SpaceX will give the United States back access to space, less expensive than its previous programs. For three billion granted since 2011 under a fixed price contract, SpaceX has fully developed a new space taxi and promised six round trips to the ISS. Previously, the space agency ordered a specific vehicle from industry giants, and assumed all budget overruns.
In doing so, the ex-start-up beat Boeing, whose Starliner capsule, developed for the same purpose, missed an empty test flight last year and won't be ready until 2021 at the earliest.

On May 30, the company of Elon Musk, also boss of Tesla electric vehicles, had achieved a first feat by transporting Bob Behnken and Doug Hurley to the orbital laboratory, doing for humans what it has done regularly for the cargo since 2012.
Donald Trump had attended the takeoff in person from Florida, and he had applauded the boss of SpaceX. “Today's launch demonstrates that the future belongs to the private space industry,” the US president said. This Sunday, he was delighted with the return to Earth of the capsule. “It's great to see our NASA astronauts come back to Earth after two months of a very successful mission. Thanks everyone !! ” tweeted the US president
A SpaceX ship, GO Navigator, is in the area and must pick up the crew, who will immediately undergo medical examinations before being returned to dry land.
The Dragon Crew capsule will be transported to a SpaceX site in Florida for a six-week inspection to verify that it can again serve as a space taxi, in this case for the spring 2021 mission with Thomas Pesquet on board.
