Barring weather or other unforeseen problems, the 24-storey-tall Falcon 9 rocket is due to lift off at 9.22pm GMT, propelling astronauts DougHurley and Bob Behnken on a 19-hour ride to the International Space Station.
Although the Crew Dragon is capable of spending 110 days in space, NASA reports the actual length of the mission will be decided by how quickly the next shuttle can get ready for launch. Johnson Center Director Mark Geyer, International Space Station Program Deputy Manager Kenneth Todd, NASA Commercial Crew Program Deputy Manager Steve Stich, and also NASA Astronaut Kjell Lindgren additionally are going to take part in the online media rundown show on NASA Television and also the company's internet site.
They will be carried inside the newly designed Crew Dragon capsule, making its first flight into orbit with humans on board. They will join three crewmates already living onboard the ISS, Russian cosmonauts Ivan Vagner and Anatoly Ivanish, including NASA astronaut Chris Cassidy. Just earlier than lift-off, Hurley mentioned, "SpaceX, we're go for launch".
"You can bet we will take it with us when we depart back to Earth", Hurley said as he presented the flag.
US President Donald Trump attended the liftoff, which was also watched by almost 4,000 people at the Kennedy Space Center. According to Colonel US air force, who has previously participated twice in the space missions Space Shuttle, the voyagers expected from the device more smooth. "But then you fold into that the historic aspect of the whole day and what it means it means to America, what it means to our space program".
"I thank and congratulate Bob Behnken, Doug Hurley, and the SpaceX and NASA teams for this significant achievement for the United States". NASA had been shelling out tens of millions of dollars for every Soyuz seat. Named the Starliner, it failed to reach the ISS in an unmanned test in December a year ago after experiencing trouble with its flight-control system.
If the mission turns out to be a success, the crew for the next flight, possibly in late August, will include Japanese astronaut Soichi Noguchi, 55.
"The race isn't over until it's over", Behnken told reporters ahead of the launch. From the mission participants had the impression that they drag him into the orbit of the ISS. Trump said he plans to return for Saturday's attempt.
