Shape is everything. Reentry from the Moon or Mars is much faster than from orbit. If the walls slope back at the angle of the Apollo (IIRC 35 degrees) then they don't have to endure the effects of heating. In a craft like the Soyuz the side walls are less sloped, but it is limited to orbital reentry. The laws of physics don't change from 60s to 90s to 2020. And they determine the shape of a ship designed for use outside of Earth orbit.

My issue has always been with the booster. The stick is not projected to have enough thrust. And as a result they are having to cut more and more mass off of the Orion. I'm worried they may end up putting the crew at risk due to an under powered booster.
