Boeing launched its Starliner capsule Friday on a crewless eight-day journey to the International Space Station and back, but the mission ran into early trouble with its orbit procedure.
The test flight is a key part of NASA's plans to end US dependence on Russia for space rides, with the reputational stakes high.
Starliner, which is fixed to the summit of a giant Atlas V rocket, took off shortly before sunrise at 6:36am local time (1136 GMT) from Cape Canaveral, separating 15 minutes later.
"Starliner is free flying for the first time in space," said an announcer on NASA TV.
But a short time later, Boeing announced on Twitter it had a "off-nominal insertion," indicating its orbital procedure had not gone as planned, as on-air announcers said that mission control was weighing all its options.
The mission's main payload is the bandana-clad dummy Rosie, named after Rosie the Riveter, the star of a campaign aimed at recruiting women to munitions factory jobs during World War II that featured her wearing blue overalls and flexing a bicep.
NASA has been forced to rely on Russian Soyuz rockets to transport its astronauts since the Space Shuttle program was shuttered in 2011 following thirty years of service.
Under former president Barack Obama, NASA opted for a shift in how it operates: instead of owning the hardware, it would hire private companies to take over the role, awarding Boeing and SpaceX billions of dollars to develop "Made in the USA" solutions.
Both companies are running two years behind schedule but appear almost ready, and approval now rests on the successful completion of final tests.
"By early next year, we're going to be launching American astronauts on American rockets from American soil again for the first time since the retirement of the space shuttles back in 2011," NASA administrator Jim Bridenstine told reporters Thursday at the Kennedy Space Center.
SpaceX already carried out its own successful uncrewed mission to the International Space Station (ISS) back in March, when its CrewDragon docked with the station and returned to Earth carrying the dummy "Ripley"—named after Sigourney Weaver's character in the film "Alien."
The dummies are packed with sensors to verify the voyage will be safe for future teams of humans.
"It's been eight and a half years, far too long, in my opinion," said Boeing astronaut Chris Ferguson, who commanded the last Shuttle mission in 2011 and is set to be on Starliner's first crewed mission.
"But here we are right on the threshold of getting ready to do it," he added.
The developments are independent of the Artemis program to return to the Moon by 2024, which will use a spaceship built for longer journeys into space, Lockheed Martin's Orion.
$8 billion payment
About 25 hours after launch, the Starliner is supposed to dock autonomously with the space station, 250 miles (400 kilometers) above sea level.
Its return to the Earth, in the southwest US, is set for December 28.
NASA has committed to pay a total of $8 billion to the two companies, who in return need to deliver six trips carrying four astronauts each time, up until 2024.
A recent report by NASA's inspector general said the cost per astronaut comes to about $90 million for Boeing, against $55 million for SpaceX, while the US currently pays Russia more than $80 million for the same.
But both Bridenstine and Boeing contest the numbers, which were calculated by taking the total sums paid by the space agency to each company and divided by the number of missions and astronauts.
SpaceX has the benefit of receiving billions of dollars in earlier contracts to develop the Dragon's first version, for cargo, which was modified to make the crew version.
Bridenstine expressed his confidence in Boeing after its 737 Max debacle.
"I would also say that if you look at Boeing as an institution, the people that develop spacecraft are not the same people that develop aircraft," he said.
