Boeing’s beleaguered Starliner returned to Earth from the Worldwide House Station (ISS) with out astronauts Sunita Williams and Barry E Wilmore.
The gumdrop-shaped capsule landed gently on the White Sands House Harbor in New Mexico at roughly 0401 GMT (9:30 am), its descent slowed by parachutes and cushioned by airbags, having departed the ISS round six hours earlier.

After years of delays, Starliner launched in June for what was meant to be a roughly weeklong check mission — a last shakedown earlier than it might be licensed to ferry crew to and from the orbital laboratory.
However surprising thruster malfunctions and helium leaks on its means up derailed these plans, and NASA finally determined it was safer to deliver Butch Wilmore and Suni Williams again on a rival SpaceX Crew Dragon — although they’re going to have to attend till February 2025.
The gumdrop-shaped capsule touched down softly on the White Sands House Harbor in New Mexico at roughly 0401 GMT, its descent slowed by parachutes and cushioned by airbags, having departed the ISS round six hours earlier.
Floor groups reported listening to sonic booms because it streaked purple scorching throughout the evening sky, having endured temperatures of three,000 levels Fahrenheit (1,650 levels Celsius) throughout atmospheric reentry.
A clean, uneventful experience was seen as vital not just for salvaging some pleasure but in addition for Boeing’s prospects of reaching certification sooner or later.
The century-old aerospace big had carried out intensive floor testing aimed toward replicating the technical points the spaceship had skilled on its ascent and devised plans to stop extra issues.
With its repute already battered by security issues affecting its passenger jets, Boeing made assurances in public and in personal that it might be trusted to deliver the astronauts dwelling — an evaluation not shared by NASA.
“Boeing believed within the mannequin that they’d created that attempted to foretell the thruster degradation for the remainder of the flight,” Steve Stich, program supervisor for NASA’s Business Crew Program, instructed reporters this week.
However “the NASA workforce, as a result of uncertainty within the modeling, couldn’t get snug with that,” he added, characterizing the temper throughout conferences as “tense.”
– Certification choices to come back –
Shortly after undocking, Starliner executed a strong “breakout burn” to swiftly clear it from the station and stop any threat of collision — a maneuver that might have been pointless if crew have been aboard to take handbook management if wanted.
Following that, mission groups carried out thorough checks of its thrusters in preparation for the vital “deorbit burn,” required to information the capsule onto its reentry path round 40 minutes earlier than touchdown.
Whereas expectations have been excessive that Starliner would stick the touchdown, because it had in two earlier uncrewed checks, NASA will now fastidiously evaluation all features of the mission’s efficiency earlier than deciding on the subsequent steps.
NASA awarded Boeing and SpaceX multibillion-dollar contracts over a decade in the past to develop spacecraft to taxi astronauts to and from the ISS, after the top of the House Shuttle program left the US house company reliant on Russian rockets.
Though initially thought of the underdog, Elon Musk’s SpaceX surged forward of mighty Boeing, efficiently flying dozens of astronauts since 2020.
The Starliner program, in the meantime, has confronted quite a few setbacks.
In 2019, throughout its first uncrewed check flight, a software program glitch prevented the capsule from rendezvousing with the ISS. A second software program concern, which may have triggered a catastrophic collision between its modules, was caught and stuck simply in time.
In 2021, with the rocket poised on the launchpad for an additional try, blocked valves pressured one more postponement.
The capsule lastly reached the ISS in Might 2022 on a non-crewed flight, however additional points, together with weak parachutes and flammable tape within the cabin that wanted removing, delayed the crewed check.
For the present mission, astronauts Wilmore and Williams had been strapped into their seats and able to fly twice earlier than last-minute “scrubs” attributable to technical glitches despatched them again to their quarters.
