NASA's Artemis 1 moon mission completed a crucial preflight milestone today (June 20), wrapping up a two-day set of tests known as a wet dress rehearsal.
Those tests included fueling up Artemis 1's huge Space Launch System (SLS) rocket and performing a simulated countdown that took the vehicle and NASA's Orion capsule through most of the progressions they would endure on launch day before engine ignition. The simulated countdown reached its conclusion at 7:37 p.m. EDT (2337 GMT), bringing an end to the wet dress.
Not everything went perfectly smoothly. The Artemis 1 team noticed a hydrogen leak during fueling today, and they intentionally "masked" data associated with the issue to let the countdown continue. (During an actual launch countdown, such data would have raised red flags, NASA officials said.) This change meant the countdown was halted at T-29 seconds before "liftoff," instead of T-9 seconds as originally planned.

It seems to me that a hydrogen leak is not a small thing.
With all the diversity NASA has turned into Tower of Babel
Just a small leak - good enough for government work.
Not really, nasa has always been full of acronyms
Na they have to roll it back to the assembly building to finish adding finishing touches
Oh it's in line with this administration and all its emphasis on diversity. Hydrogen molecules are smaller than oxygen molecules so you have to make an adjustment and allow hydrogen molecules to leak more to make it all fair and equitable.

Paint and polish the brass until it shines?
Not getting a warm a fuzzy feeling about this gigantic potential bomb. A perfect example of just how wasteful and stupid the direction of our space program is the cancelation of making any more Saturn 5 rockets. An already well designed heavy lift booster that WORKED .....
First rule of flight: Never take off with your motor leaking.
Hydrogen and Oxygen molecules must be the same size or its unfair discrimination and racist!
The first Orion launch was Dec. 2014. I can't imagine having stayed around for this mission.
Working NASA programs was more infuriating than rewarding.
So it passed the test because they cheated on the test.
Nope. Done a few loadings in the past. Hydrogen leaks are not good. Folks think a crew comes in a pushes the button but the actual work was usually about a 4 day event from start of countdown to launch.
And the last NASA launch of a crew was July 2011. Not much lag time between programs.
Lag time is a big part of NASA’s problem. Huge lag between Apollo and STS, huge lag between STS and this fiasco. There should have been continual, organic, evolutionary development from Saturn-V to the present day.
Unsurprisingly, blame for most of this lies at the feet of racist, communist “democrats” in Congress.
Yup. Lag time between Apollo and Shuttle wasn’t this bad. And the Shuttle was retired with a lot of life left on the vehicles.
It's OK because two hydrogens get to gang up on one oxygen for a neutral, equitable outcome.
Has NASA been corrupted like the other once-revered agencies?
