Boeing astronaut capsule grounded for months by valve challenge

In this June 2, 2021 image produced obtainable by NASA, professionals prepare Boeing’s CST-100 Starliner for the company’s Orbital Flight Test-2 (OFT-2) in the Professional Crew and Cargo Processing Facility at NASA’s Kennedy Room Heart in Florida. On Friday, Aug. 13, 2021, Boeing and NASA officials stated the capsule is grounded for months and maybe even until future calendar year due to the fact of a vexing valve issue.

Boeing’s astronaut capsule is grounded for months and potentially even until finally next year due to the fact of a vexing valve issue.


Boeing and NASA officers said Friday that the Starliner capsule will be eliminated from the top of its rocket and returned to its Kennedy Place Center hangar for a lot more intensive repairs.

Starliner was poised to blast off on a repeat test flight to the Intercontinental Area Station very last week—carrying a mannequin but no astronauts—when the issues arose. A comparable capsule was plagued by application challenges in 2019 that prevented it from achieving the area station.

“We are certainly unhappy,” claimed John Vollmer, vice president and plan manager of Boeing’s commercial crew program. “We will fly this check when we’re completely ready to fly it and it truly is harmless to do so.”

Kathy Lueders, head of NASA’s human exploration business office, stated it is really “an additional instance of why these demo missions are so quite significant to us … to make positive we have the program wrung out before we set our crews on.”

Boeing’s overall performance is in stark contrast to that of SpaceX, NASA’s other contracted taxi provider. SpaceX has flown 10 astronauts to the house station in just above a calendar year, with four much more because of to start aboard the company’s Dragon capsule at the conclusion of Oct. Elon Musk’s company will mark one more 1st up coming thirty day period when it launches a billionaire into orbit with three visitors, two of them contest winners.

Vollmer explained moisture in the air in some way infiltrated 13 valves in the capsule’s propulsion method. That humidity blended with a corrosive gas-burning chemical that had gotten earlier seals, avoiding the valves from opening as essential right before the Aug. 3 start endeavor.

As of Friday, 9 of the valves had been mounted. The other four call for much more invasive get the job done.

Rain from a serious thunderstorm penetrated some of the capsule’s thrusters at the pad, but engineers do not imagine that is the very same moisture that induced the valves to stick. Engineers are striving to determine how and when the moisture acquired there it could have been for the duration of assembly or much later, Vollmer reported.

The 13 in problem are amongst dozens of valves that are tied into thrusters essential to get the capsule into the appropriate orbit and to the place station, and to also re-enter the ambiance at flight’s conclude. All the valves labored wonderful 5 months previously and done very well in the 2019 check flight, Vollmer said.

Vollmer explained it is much too quickly to know irrespective of whether the valves will want to be replaced or even redesigned. Aerojet Rocketdyne provided the valves, alongside with the relaxation of the propulsion program.

Given all the uncertainty, Vollmer was unwilling to say when Starliner may possibly be all set for yet another start try. Boeing will will need to function all-around other place station traffic, as effectively as a NASA asteroid mission that is owing to launch on the same variety of rocket from the very same pad in Oct.

“Most likely way too early to say regardless of whether it truly is this yr or not,” Vollmer advised reporters.
