Onboard the inaugural launch of Boeing's Starliner capsule will be two NASA astronauts bound for the International Space Station (ISS).
ADVERTISEMENTBoeing successfully launched a crewed Starliner capsule into orbit on Wednesday for the first time after safety concerns had previously grounded the manned spacecraft.
It was the third launch attempt for NASA test pilots Butch Wilmore and Suni Williams, the first paid of astronauts to fly the new craft, who are now bound for the International Space Station (ISS).
A reported leak had thwarted the first two countdowns at Florida's Cape Canaveral.
The astronauts will test Starliner’s systems on the way to the ISS, where they'll spend at least a week before aiming for a touchdown in the western United States.
"Let’s get going!" Wilmore called out a few minutes before liftoff.
Half an hour later, he and Williams were safely in orbit and giving chase to the space station.
The relieved launch controllers stood and applauded. After all the trouble leading up to Wednesday's launch, including two scrapped countdowns, everything seemed to go smoothly before and during liftoff.
Years late because of spacecraft flaws, Starliner’s crew debut comes as the company struggles with unrelated safety issues on its airplane side.
Wilmore and Williams - retired Navy captains and former space station residents - stressed repeatedly before the launch that they had full confidence in Boeing's ability to get it right with this test flight.
Crippled by bad software, Starliner’s initial test flight in 2019 without a crew had to be repeated before NASA would let its astronauts strap in.
The 2022 do-over went much better, but parachute problems later cropped up, and flammable tape had to be removed from the capsule.
Postponements due to a helium leak
Wednesday's launch was the third attempt with astronauts since early May, coming after a pair of rocket-related problems, most recently last weekend. A small helium leak in the spacecraft’s propulsion system also caused delays, but managers decided the leak was manageable and not a safety issue.
"I know it’s been a long road to get here," NASA's commercial crew program manager Steve Stich said before the weekend delay.
Boeing was hired alongside Elon Musk's SpaceX a decade ago to ferry NASA’s astronauts to and from the space station.
The space agency wanted two competing U.S. companies for the job in the wake of the space shuttles’ retirement, paying $4.2 billion (€3.8 billion) to Boeing and just over half that to SpaceX, which refashioned the capsule it was using to deliver station supplies.
ADVERTISEMENTSpaceX launched astronauts into orbit in 2020, becoming the first private business to achieve what only three countries - Russia, the US, and China - had mastered. It has taken nine crews to the space station for NASA and three private groups for a Houston company that charters flights.
The liftoff from Cape Canaveral Space Force Station was the 100th of an Atlas V for rocket maker United Launch Alliance.
Boeing joining SpaceX as a taxi
It was the first ride for astronauts on an Atlas rocket since John Glenn’s Mercury era more than 60 years ago; the rocket usually launches satellites and other spacecraft.
Despite the Atlas V’s perfect record, the human presence cranked up the tension for the scores of NASA and Boeing employees gathered at Cape Canaveral and Mission Control in Houston.
ADVERTISEMENTBoeing’s Starliner and SpaceX's Dragon are designed to be fully autonomous and reusable. Wilmore and Williams occasionally will take manual control of Starliner on their way to the space station, to check out its systems.
If the mission goes well, NASA will alternate between SpaceX and Boeing for taxi flights, beginning next year. The backup pilot for this test flight, Mike Fincke, will strap in for Starliner’s next trip.
"This is exciting. We built up to this moment for years and years, and it finally happened," Fincke said from neighboring Kennedy Space Center. "I feel like the whole planet was cheering for them".
