Boeing’s Starliner area capsule landed in the New Mexico desert Wednesday, completing a six-day mission in which it eventually achieved the Global Area Station and that could direct to flights with astronauts.

The capsule, devoid of any crew on board, touched down as scheduled at 6:49 p.m. Eastern time at the White Sands Missile Range in New Mexico under a trio of parachutes. Air bags cushioned the landing.

The landing was the last move of a important exam for Boeing and NASA, which needed the aerospace corporation to demonstrate it could properly fly the vehicle to the station and back again autonomously in advance of permitting it to fly astronauts.

The return flight went smoothly, NASA and Boeing reported, from undocking with the area station, then firing its thrusters to deorbit and entering the environment. As it plunged back again toward Earth, its heat defend endured temperatures as substantial as 3,000 degrees Fahrenheit.

“Just a gorgeous touchdown in White Sands this night,” Lauren Seabrook, a Boeing spokesperson, mentioned on the reside broadcast of the landing.

She extra that the spacecraft landed about three-tenths-of-a-mile southeast of the landing site, “which is basically a bull’s eye,” she stated.

It is unclear, nevertheless, when the very first crewed flight would occur.

On its way to the station, two of its major thrusters slice off immediately after sensors recorded challenges. Backups kicked in without hold off, placing the spacecraft on the correct route to the station, but the moment it got shut to the station, two other, smaller sized thrusters, utilised to posture the spacecraft for docking, also had issues, Boeing explained. In addition, the spacecraft’s thermal command system, used to maintain the spacecraft at the correct temperature, also failed.

Inspite of individuals challenges, NASA and Boeing hailed the mission as a “historic” to start with that would give the house agency an option to SpaceX for carrying cargo and astronauts to the station. Mark Nappi, a Boeing vice president who oversees the Starliner plan, reported that regardless of the troubles, the “spacecraft is in great issue,” and that it “performed like it was meant to.”

Steve Stich, who runs NASA’s professional crew software, said very last week that the difficulties had been get over with out also a great deal difficulties but that the “failures” would have to be researched.

“We have a good deal of redundancy so that definitely did not influence the rendezvous operations at all or influence the relaxation of the flight,” he mentioned soon after the docking. “I know soon after the flight, we’ll go review the failures there and see what took place.”

That investigation is produced extra complicated by the truth that engineers on the ground won’t be equipped to look at the two most important thrusters that cut out given that they are housed in the spacecraft’s service module, which was jettisoned during the return.

Nonetheless, NASA and Boeing celebrated the flight as a accomplishment. During a post-flight briefing Wednesday night, Stich explained the “test flight was incredibly productive. We met all the mission goals.” He additional that “the systems executed good on the vehicle and, you know, when we get the job done as a result of all the info, we’ll be all set to fly the crew on the car or truck.”

While there ended up several challenges along the way, he stated there have been no “showstoppers.” Regardless of the troubles with the thrusters, he reported, “I do not see any motive why we can not carry on toward a crewed flight check up coming.”

Nappi added that “we are very happy with the final result of this mission.”

Boeing and NASA have reported they would like to be in a position to fly a mission with astronauts by the close of the 12 months, but they would very first want to make confident they understand all of the challenges that cropped up as nicely as study the details they have from the capsule now that it is back again on the ground.

The plan is currently delayed by many years right after a sequence of prior issues. Boeing initial tried the uncrewed exam flight in December 2019. But it experienced to slash the test brief after a big software problem and a communications failure prompted the spacecraft to melt away way too a great deal gasoline and not enter an orbit that would have it to the house station. It took 20 months before the enterprise experimented with once more, but that flight failed even to get off the ground past August when engineers uncovered that 13 valves in the assistance module were being stuck in the shut place.
