I have no special knowledge about why they went the exposed inflatable route, except to say that throwing Mars dirt around was probably judged to be a mistake.

I think these horizontal rectangular concepts originated with Brand Griffin of Boeing; Paul Hudson painted them, so they became pretty well known.

SLS design payloads are all over the map, and I expect we won't know for certain what that family of rockets will be able to do until we get some flight data. However, a quick peek at Wikipedia suggests payloads of from 70 to 130 metric tons. The most capable SLS design is meant to exceed Apollo David S. F.

At the moment, there's a lot of interest in interim steps.

I have read your posts on the space station planning and the designs are all over, from a simple lab to a full scale spacedock. Right now it seems that NASA has chosen Solar Electric Propulsion for the Mars bound spacecraft, though the ISRU unit might be nuclear.
