“But of course, if you want to reinvent the wheel by building a spacecraft with a very high centre of gravity and a narrow landing gear, spaceflight suddenly becomes difficult again.”
As I understand it most of the upper structure on Odysseus was light weight so how high was the CoG and probably more importantly what were the tilt limits?
That said I think an increasing number of eyebrows are going to be raised at the proposals for the Human Landing System (HLS) on Artemis, and maybe also any thoughts that the landing on that system can be completely handed off to automation with no facility for manual reversion.
