Boeing's Starliner capsule returned to Earth Wednesday in the final step of a key uncrewed test flight to prove itself worthy of providing rides for NASA astronauts to the International Space Station.
The spaceship landed in a puff of sand at 4:49 pm local time (2249 GMT) in the New Mexico desert, wrapping up a six-day mission crucial to restoring Boeing's reputation after past failures.

The spaceship landed in a puff of sand at 4:49 pm local time (2249 GMT) in the New Mexico desert, wrapping up a six-day mission crucial to restoring Boeing's reputation after past failures.
"Just a beautiful touchdown in White Sands this evening," said an announcer on a NASA live feed, as a recovery team quickly raced to the landing site.
Orbital Flight Test-2 (OFT-2) was the last hurdle for Starliner to clear before it carries humans in another test flight that could take place by the end of this year.
- Landing airbags -
Starliner docked with the ISS on Friday, a day after blasting off from the Kennedy Space Center in Florida.
Over the weekend, astronauts living aboard the research platform opened the hatch and "greeted" the capsule's passengers: Rosie the Rocketeer, a sensor-equipped mannequin, and a plush toy named Jebediah Kerman, a video game character and the ship's zero-g indicator.
The spacecraft brought back more than 600 pounds (270 kilograms) of cargo, including reusable tanks that provide breathable air to station crew members, which will be refurbished and taken back up on a future flight.
As it flew over the Pacific Ocean, Starliner initiated a de-orbital maneuver, and then ejected its expendable service module, leaving the remaining crew module to withstand temperatures of around 3000 degrees Fahrenheit (1650 Celsius) during atmospheric re-entry.
Having shed most of its velocity, it deployed a series of parachutes culminating in its three giant main chutes, colored red, white and blue. At 3,000 feet, it jettisoned its base heat shield -- revealing airbags that aided a gentle landing.
The mission wasn't without its hiccups, which NASA and Boeing teams are expected to probe thoroughly in case they could cause future problems.
Two thrusters responsible for placing Starliner in a stable orbit failed, though officials insisted there was plenty of redundancy built into the system to overcome the problem.
On the day of docking, the vessel missed its scheduled contact time by more than an hour, after a ring responsible for latching on to the station failed to deploy correctly. Engineers had to retract the ring and pop it out again before it worked the second time.
- Second taxi service -
Still, the glitches were minor compared to the troubles Starliner saw during its first test launch, back in 2019, when one software bug caused it to burn too much fuel to reach its destination, and another almost meant that the vehicle was destroyed during re-entry.
The second error was caught in time to upload a patch, and the vessel was able to achieve a gentle landing at White Sands Space Harbor -- the same spaceport where the space shuttle Columbia once landed, and where Starliner touched down once more on Wednesday.
Boeing and NASA also tried to launch Starliner in August 2021, but the capsule was rolled back from the launchpad to address sticky valves that did not open as they should. The ship was eventually sent back to the factory for fixes.
NASA is looking to certify Starliner as a second "taxi" service for its astronauts to the space station -- a role that Elon Musk's SpaceX has provided since succeeding in a test mission for its Dragon capsule in 2020.
Both companies were awarded fixed-price contracts -- $4.2 billion to Boeing and $2.6 billion to SpaceX -- in 2014, shortly after the end of the space shuttle program, during a time when the United States was left reliant on Russian Soyuz rockets for rides to the orbital outpost.

Boeing's Starliner spaceship docks with ISS in high-stakes test mission
Washington (AFP) May 21, 2022
Boeing's Starliner capsule docked with the International Space Station Friday, a major milestone in a high-stakes uncrewed test flight as the US aerospace giant seeks to restore its reputation following past failures. The spaceship made contact at 8:28 pm Eastern time (0028 GMT Saturday), a little over 24 hours after it blasted off from the Kennedy Space Center in Florida on a mission to prove itself capable of providing safe rides for NASA astronauts.
