Elon Musk's rocket company SpaceX was set to launch early on Monday the International Space Station's next long-duration team into orbit, with an astronaut from the United Arab Emirates and a Russian cosmonaut joining two NASA crewmates for the flight.
The SpaceX launch vehicle, consisting of a Falcon 9 rocket topped with an autonomously operated Crew Dragon capsule called Endeavour, was set for liftoff at 1:45 a.m. EST (0645 GMT) from NASA's Kennedy Space Center in Cape Canaveral, Florida.
The four-member crew should reach the International Space Station (ISS) about 25 hours later, on Tuesday morning, to begin a six-month mission in microgravity aboard the orbiting laboratory some 250 miles (420 km) above Earth.
Designated Crew 6, the mission marks the sixth long-term ISS team that NASA has flown aboard SpaceX since the private rocket venture founded by Musk - billionaire CEO of electric car maker Tesla (TSLA.O) and social media platform Twitter - began sending American astronauts to orbit in May 2020.
