Meanwhile, SpaceX and Blue Origin are launching tourists in their capsules.
doesn’t know with 100 percent certainty what caused 13 of those valves to remain shut when they should have been open...
Software. Even in autos it’s getting too complex to predict.
Time to just cancel their contract. And while they’re at it they could cancel SLS, Artemis, and Orion.
Soon as Starship orbits the earth with reusable rockets the entire situation in space is changed forever.
Problem Identified
MADE IN CHINA
Boeing ain’t going.
Boeing has been tethered to fedgov for so long it’s become as efficient as fedgov. Overweight sloth.
In the mean time all the true private spacecraft manufacturers are moving ahead with success after success. Maybe there’s a lesson in this for NASA?
13? Lucky number.
Maybe now they’ll try doing an integrated test, rather than looking at a bunch of specifications and figuring that it ‘should’ all work together.
There are today Chinese made parts in Boeing’s most recent aircraft models. Sabotage, via malware in some Chinese-made circuit board???
Sure looks good for self driving cars and big rigs... Lot more where this came from.
It doesn’t sound to me like a software or electrical problem
“According to NASA’s chief of human spaceflight operations, Kathy Lueders, engineers have been gathering data about the “dry” side of the valves. The hope is the team will be able to determine the cause and find a fix for the stuck valves from this limited perspective. However, it may become necessary to look at the internal or “wet” side of the valves, and that will mean going through the tedious process of disassembling the propulsion system. “
They think it was caused by their capsule getting rained on before the launch attempt
“John Vollmer, vice president and program manager of Boeing’s commercial crew program, said on the media call that the leading cause of the valve problem is that nitrogen tetroxide (NTO), the oxidizer used for Starliner’s thrusters, permeated Teflon seals in the valves. That NTO interacted with moisture on the “dry” side of the valve, creating nitric acid. The acid corroded the valves, causing them to stick in the closed position.”
I can’t believe that they haven’t replaced all the valves by now.
