The mods will clean it up before launch time. It's typical chat BS on EVERY launch, regardless of which country is launching.

Alrighty then.

Tonight's launch attempt scrubbed due to an issue with one of Atlas V's solid rocket boosters (SRB).

EDIT: Centaur oxygen relief valve is reportedly the issue.

If memory serves (ha), the male astronaut is 61 yo and the female is 58.

Both have good experience levels.

She's a rotor wing pilot, he's fixed wing.

Unless Boeing has already divested itself from the ULA partnership to a secret buyer, it's definitely a Boeing problem even if it's not directly a Starliner issue.


The next launch opportunity will be Friday night at 9 pm EDT.  The valve cycling issue seems to have been resolved, but engineers are trying to determine if it exceeded its certified service life opening & closing 40 times/sec. If so, they'll likely have to roll back to replace it and delay further.

NASA’s Boeing Crew Flight Test now is targeted to launch no earlier than 6:16 p.m. EDT Friday, May 17, to the International Space Station. Following a thorough data review completed on Tuesday, ULA (United Launch Alliance) decided to replace a pressure regulation valve on the liquid oxygen tank on the Atlas V rocket’s Centaur upper stage.

ULA plans to roll the rocket, with Boeing’s Starliner spacecraft, back to its Vertical Integration Facility at Cape Canaveral Space Force Station in Florida on Wednesday, May 8, to begin the replacement. The ULA team will perform leak checks and functional checkouts in support of the next launch attempt.

The oscillating behavior of the valve during prelaunch operations, ultimately resulted in mission teams calling a launch scrub on May 6. After the ground crews and astronauts Butch Wilmore and Suni Williams safely exited from Space Launch Complex-41, the ULA team successfully commanded the valve closed and the oscillations were temporarily dampened. The oscillations then re-occurred twice during fuel removal operations. After evaluating the valve history, data signatures from the launch attempt, and assessing the risks relative to continued use, the ULA team determined the valve exceeded its qualification and mission managers agreed to remove and replace the valve.

There has been a string of valve malfunctions during the run up to these launches.

I wonder what changed.

I haven't compared the count down timeline with unmanned atlas launches but possibly there is new built in time for crew loading that has this valve active longer.

I also read somewhere that historically they have cycled these valves and it typically settles down and acts right so they waiver and send it but with this being manned the rules are changed.

These guys put out a lot of transparency with their launch operations which is pretty cool and informative but is also fuel for the haters.

Maybe i missed if this was posted in here but Ms Faville is the president of valve tech, a woman owned company that is a vendor for starliner.

Valve tech president warnings



In response, the CEO of United Launch Alliance (ULA), the company launching Boeing’s spacecraft into orbit, disputed ValveTech’s claims on X, writing, “Not sure what to say about this one. Close to none of it is correct. Not urgent. Not leaking. Etc. Remarkable that the particular person quoted doesn’t seem to know how this type of valve works…”

NASA’s Boeing Crew Flight Test Eyes Next Launch Opportunity

May 14, 2024

NASA, Boeing, and ULA (United Launch Alliance) teams continue working remaining open tasks in preparation for the agency’s Boeing Crew Flight Test to the International Space Station. The teams now are targeting a launch date of no earlier than 4:43 p.m. EDT on Tuesday, May 21, to complete additional testing.

On May 11, the ULA team successfully replaced a pressure regulation valve on the liquid oxygen tank on the Atlas V rocket’s Centaur upper stage. The team also performed re-pressurization and system purges, and tested the new valve, which performed normally.

Starliner teams are working to resolve a small helium leak detected in the spacecraft’s service module traced to a flange on a single reaction control system thruster. Helium is used in spacecraft thruster systems to allow the thrusters to fire and is not combustible or toxic.

NASA and Boeing are developing spacecraft testing and operational solutions to address the issue. As a part of the testing, Boeing will bring the propulsion system up to flight pressurization just as it does prior to launch, and then allow the helium system to vent naturally to validate existing data and strengthen flight rationale. Mission teams also completed a thorough review of the data from the May 6 launch attempt and are not tracking any other issues.

The Atlas V and Starliner remain in the Vertical Integration Facility at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida.

NASA astronauts Butch Wilmore and Suni Williams, still in preflight quarantine, returned to Houston on May 10 to spend extra time with their families as prelaunch operations progress. The duo will fly back to NASA’s Kennedy Space Center in Florida in the coming days.

If they do, their standard comment is standing down for some extra ground checks.

While I'm sure we would have eventually learned about the capsule abort rockets issue because it was for NASA CCP. If it wasn't for the huge hyper cloud heading offshore seen from Cocoa Beach and the leaked video, how much would we really know?

NASA, Boeing now working toward May 25 launch of Crew Flight Test

NASA, Boeing, and ULA (United Launch Alliance) teams will take additional time to work through spacecraft closeout processes and flight rationale before proceeding with the launch of the agency’s Boeing Crew Flight Test. The teams now are targeting a launch no earlier than 3:09 p.m. EDT Saturday, May 25, for the flight test carrying NASA astronauts Butch Wilmore and Suni Williams to the International Space Station.

The additional time allows teams to further assess a small helium leak in the Boeing Starliner spacecraft’s service module traced to a flange on a single reaction control system thruster. Pressure testing performed on May 15 on the spacecraft’s helium system showed the leak in the flange is stable and would not pose a risk at that level during the flight. The testing also indicated the rest of the thruster system is sealed effectively across the entire service module. Boeing teams are working to develop operational procedures to ensure the system retains sufficient performance capability and appropriate redundancy during the flight. As that work proceeds, NASA’s Commercial Crew Program and the International Space Station Program will take the next few days to review the data and procedures to make a final determination before proceeding to flight countdown.

The ULA Atlas V rocket and Boeing’s Starliner remain in the Vertical Integration Facility at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida. The NASA, Boeing, and ULA teams remain committed to ensuring a safe Starliner flight test.

If Boeing kills those astronauts the company will go under.  They can't afford that public safety blemish on top of the door blowing off the 37 and the Max safety problems related to the engine mounting location.
