SpaceX launched four astronauts on a flight to the International Space Station on Sunday, NASA’s first full-fledged mission to send a crew into orbit on board a privately owned spacecraft.
SpaceX’s newly designed Crew Dragon capsule, which the crew has dubbed Resilience, lifted off atop a SpaceX Falcon 9 rocket at 7:27pm eastern time (00:27 GMT on Monday) from NASA’s Kennedy Space Center in Cape Canaveral, Florida.“That was one heck of a ride,” astronaut Mike Hopkins said from Crew Dragon to SpaceX mission control about an hour after liftoff. “There was a lot of smiles.”
Crew Dragon will gradually raise its orbit for the next 27 hours through a series of onboard thruster firings, aiming to dock at the International Space Station at 11pm eastern time on Monday (04:00 GMT).
An air leak caused an unexpected drop in capsule pressure less than two hours before launch, NASA officials said. But technicians said they conducted a successful leak check and the scheduled launch was still on.
The 27-hour ride to the space station, an orbiting laboratory some 250 miles (400 kilometres) above Earth was originally scheduled to begin on Saturday. But the launch was postponed for a day due to forecasts of gusty winds – remnants of Tropical Storm Eta – that would have made a return landing for the Falcon 9’s reusable booster stage difficult, NASA officials said.
SpaceX mission operator Jay Aranha, speaking from the company’s Hawthorne, California headquarters, told the crew to “have an amazing trip, and know that we are all for one”.
Mission commander Mike Hopkins responded, saying “to all the people at NASA and SpaceX, by working together through these difficult times, you’ve inspired the nation the world.
“And now it’s time for us to do our part, Crew 1 for all,” Hopkins said.
US Vice-President Mike Pence attended the launch and said beforehand that under President Donald Trump, America had “renewed our commitment to lead in human space exploration”.
President-elect Joe Biden tweeted his congratulations, saying the launch was “a testament to the power of science”.
A trial flight of the SpaceX Crew Dragon in August, carrying just two astronauts to and from the space station, marked NASA’s first human space mission to be launched from US soil in nine years, following the end of the space shuttle programme in 2011. In the intervening years, US astronauts have had to hitch rides into orbit on board Russia’s Soyuz spacecraft.
The Resilience crew includes commander Mike Hopkins and two fellow NASA astronauts, mission pilot Victor Glover and physicist Shannon Walker. They were joined by Japanese astronaut Soichi Noguchi, making his third trip to space after previously flying on the US shuttle in 2005 and Soyuz in 2009.
Musk, the billionaire SpaceX chief executive who is also CEO of the electric carmaker and battery manufacturer Tesla Inc will likely not have watched the liftoff from the Kennedy Space Center launch control room, NASA officials said. Musk said on Saturday he “most likely” has a moderate case of COVID-19.
SpaceX and NASA have conducted contact-tracing and determined that Musk had not come into contact with anyone who interacted with the astronauts.
“Our astronauts have been in quarantine for weeks and they should not have had contact with anybody,” NASA Administrator Jim Bridenstine said on Friday. “They should be in good shape.”
NASA contracted SpaceX and Boeing in 2014 to develop competing space capsules aimed at replacing its shuttle programme and weaning the US off dependence on Russian rockets to send astronauts to space.
