A SpaceX webcast of the launch showed Isaacman, 38, and his crewmates - Sian Proctor, 51, Hayley Arceneaux, 29, and Chris Sembroski, 42 - strapped into the pressurized cabin of their gleaming white SpaceX Crew Dragon capsule, dubbed Resilience, wearing their helmeted black-and-white flight suits. Thumbs-up were on display as the capsule streaked into the dark sk y, perched atop one of SpaceX's reusable two-stage Falcon 9 rockets. The Crew Dragon, fitted with a special observation dome in place of its usual docking hatch, reached orbit almost 10 minutes after the p.

EDT blastoff. The rocket's first-stage booster, after separating from the spacecraft's top half, flew itself back to Earth and touched down safely on a landing platform floating in the Atlantic on a drone ship whimsically named Just Read the Instructions. Amid cheers heard in SpaceX's mission-control center as the spacecraft climbed to nearly miles km above Earth, Isaacman read a statement thanking those who made possible a journey "right to the doorstep of an exciting and unexplored frontier, where few have come before and many are about to follow.

Within three hours the capsule had reached its final cruising orbital altitude of just over miles km - higher than the International Space Station or Hubble Space Telescope, and the furthest any human has flown from Earth since NASA's Apollo moon program ended in , according to SpaceX. At that height the Crew Dragon was circling the globe once every 90 minutes at a speed of some 17, miles per hour 27, kph , or roughly 22 times the speed of sound.

The flight, representing the first crewed mission to orbit with no professional astronauts, is expected to last about three days from launch to splashdown in the Atlantic, mission officials said. It also marked the debut flight of SpaceX owner Elon Musk's new orbital tourism business, and a leap ahead of competitors likewise offering rides on rocket ships to customers willing to pay a small fortune for the exhilaration - and bragging rights - of spaceflight.

NASA, which exercised a government-run U. But Dragon was huffing and puffing all the way into orbit. So the first stage engines shut off … the first stage separates and then the Merlin Vacuum engine starts. It got a little rougher. The space agency is also working with Boeing on the Starliner crew capsule, which is now expected to launch with astronauts for the first time in early on top of a United Launch Alliance Atlas 5 rocket.

The G-force dropped off instantaneously as the Merlin Vacuum engine shut down, according to Hurley. The Merlin Vacuum engine produces around , pounds of thrust at peak performance, while the three shuttle main engines combined to generate more than 1. But the space shuttle was much larger than the Crew Dragon spacecraft and the Falcon 9 upper stage, placing the astronauts farther away from the engines.

Ground teams played the audio for Hurley and Behnken, giving the astronauts a preview of what they would experience during launch, re-entry and splashdown in the ocean. The space shuttle was fueled when the astronauts arrived at the launch pad.

Doug and I went through the fueling operation on-board Dragon, which was different for us. So hearing the venting and the valve sounds and the little vibrations associated with that operation was a new experience for us.

SpaceX designed the Crew Dragon will to be fully autonomous, without requiring manual inputs from the astronauts on-board. Her crewmate Yi So-yeon — South Korea's first astronaut — was hospitalized afterward for severe pain in her back and neck. A ballistic re-entry is kind of "like shooting a bullet out of a rifle barrel," Wiseman said. Hague and Ovchinin touched down near the town of Dzhezkazgan, Kazakhstan, 3 to 4 minutes after the anomaly occurred. They're in Baikonur, and they're healthy In photos released by NASA and Roscosmos, both Hague and Ovchinin appeared to be in good spirits, smiling as they underwent health checks and munched on a plate of assorted nuts.

According to Russia's Federal Medical Biology Agency , which has been taking care of Hague and Ovchinin since the landing, recovery teams transported the crewmembers back to Baikonur after the landing, and they are expected to return to the cosmonaut training center in Moscow tomorrow Oct.
