The launch team has recommended not proceeding with today's Artemis 1 launch attempt. Standing by for a final decision from launch director Charlie Blackwell-Thompson.
09/03 10:30
A third troubleshooting attempt to resolve the hydrogen leak at the Artemis 1 launch pad has not fixed the problem. NASA engineers are still detecting the signature of a hydrogen leak near a tail service mast umbilical line. NASA's launch team is assessing their next steps this morning.
We are a two hour drive north and it is really overcast here so not sure we could have seen it. I really hope they get this figured out, surprising to learn these leaks have plagued the Artemis quite a few times prior to this launch. I believe I read there is another system onboard that if the rocket is not launched in a certain time frame the rocket has to be taken back to the VAB to address that item.
Deploy an experiment package in situ, then head back.
That's not a good use of resources. The expensive (in the case of SLS, very expensive) part of the mission is lofting the payload into Earth orbit and then put it on a lunar trajectory. The old saw about "orbit is halfway to anywhere" is actually not much off. Once in space, you may as well spend extra time on gathering data. Increases the ROI.

Anyone familiar with that?
Here it is:
If the Artemis 1 mission can't get off the ground by Tuesday, the Space Launch System moon rocket will have to roll back to the Vehicle Assembly Building for re-testing of its flight termination system, forcing a weeks-long delay.
ARTEMIS MOONDOGGLE
Neither science nor national defense is the reason for the Lunatic Mission.
Enjoy the view of 4.2 billion dollar bills being burned up and thrown away for a propaganda stunt, partly to offset SpaceX Starship debut...(F.A.A. license delay - yeah, sure).
SpaceX Super Heavy: peak thrust of 72 MN (16 million pounds)
_ _ (99% recovered and reusable)
https://www.usdebtclock.org/
Nat.Debt: $30.867 Trillions
Fed. Budget : $5.9 T
Fed. Deficit : $1.466 T
Interest on debt: $0.433 T (annual)
Debt per taxpayer: $245,191
REMEMBER, every deficit dollar bill spent, is a tax increase in the future to repay it -and- the interest.

Nah, Every launch is a scientific one, since launches require great engineering with precision and accuracy in which the experience and knowledge gained will be used to build future spacecraft.
It is a national defense even if simple-minded people can't see it. The Chinese have landed on the far side of the moon and plans to build a base on the moon. The USA has better catch up or be left behind. It is both military and economic competition.
It is true that NASA overspends on some projects. That's why companies like SpaceX and others exit to offer cheaper alternatives.
If I have a say in how my tax money is spent, 80% of it would go to NASA.

Well no, this is exactly what they did during the lunar landing missions. Land; look around a little; leave experiments. A shorter mission means less of those expensive resources need to be taken to keep the crew alive.
Had the Senate not insisted on using the proven shuttle engines which tied the SLS to LH2 fuel, this mission might have been completed long ago for far less money. Lots of politics influenced the design of this launch system and some of the requirements destined it to be prone to problem issues.

Thats not what happened on the shuttle missions though was it? 17 days with no facilities, when a standard ISS re-stocking mission could have been done in less time? So, what was so urgent that it needed to use that longer mission time? No-one has any answers it seems.
