I wonder what the issue is/was. As an aside we seem to be having storms developing in the Atlantic for what has otherwise been a very quiet hurricane season so I wouldn't be surprised if Artemis has to be moved back to the VAB and we miss the next launch window (Sep 2).

As excited as I am about the prospect of another super-heavy launch vehicle and a manned return to the Moon, the whole SLS/Orion project still feels like a giant waste of money. We're $40 billion in and each SLS launch costs ~$4B.
