The leak went to 7% concentration but then dropped to 0.5%.  Seven percent is quite worrisome given the lower explosive limit (LEL) for hydrogen is 4%.  At 0.5% it shouldn't be a big deal unless it can find an area to collect and concentrate to higher levels.
Used to work with hydrogen gas plumbing many years ago.  It required attention to detail for sure.  My hydrogen gas leak detector sure got a workout in those days.
If there really was intelligent life on other planets, we'd be sending them foreign aid.

Conservatives see George Orwell's "1984" as a cautionary tale.  Progressives view it as a "how to" manual.

It didn't exactly drop after going to 7% they completely recycled the LH2 loading and made changes to the start of the loading procedure to see if that would help. Appears to so far have done so. At 36% load still at less than than 1%.

Gotcha.  I have classical music for dogs running in the background, and that made it hard to hear the NASASpaceflight commentary on my laptop.

They said they will allow it to go up to 10% for up to 5 minutes this time.
They're ramping up the load pressure now trying to find out at what pressures it starts having major issues.
Now at 3.4%.

Good News: They said the change in the loading procedure did the trick.
Bad News: They said they have no clue why so they don't know if it will work again on launch day.

Leak shot up, now above 4% but stable.
Despite that they're calling the test a success

If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or your arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that you were our countrymen.

The last Delta IV Heavy

Quote
United Launch Alliance (ULA) will launch the NROL-91 mission for the National Reconnaissance Office (NRO) atop a Delta IV Heavy. Launching from Space Launch Complex 6 at the Vandenberg Space Force base, in California, this mission will mark the final Delta IV Heavy launch from the west coast and the third-to-last Delta IV Heavy launch ever. ULA is retiring both the Delta and Atlas vehicles in favor of Vulcan, which is scheduled to have its maiden launch in Q1 2023.

Vulcan  :rofl: Where are my engines Jeff?  :rofl:

Scheduled to go live 17:15

Attempt to launch SLS on the 27th scrapped due to weather concerns.
May be headed back to the barn for protection.
