Those images don't look good, but I don't know how bad it really is. It sounds like they are planning a steeper reentry, high peak heat loads (and g loads probably), less heat soak time. I don't know how good their models are for that.

I'm surprised that risk-averse NASA is willing to risk this on a crewed flight without another unmanned mission, but Artemis launches are so insanely expensive that they probably have no choice from a program point of view.

I'd really like to see another manned moon landing before I die, but doubt Artemis will succeed at that.
