I might have a good idea for making a Starship landing on the moon easier/more plausible: I recently thought about how Starship can land on the moon and came to the conclusion, that landing upright comes with too many problems compared to landing horizontal, but landing horizontal has pretty much one big problem, which is the ship's shape is not built for the sideways loads. With the idea, that seems to be considered currently, which is using landing legs, this would mean, that you need structural reinforcements on the inside of the ship (outside it disturbs aerodynamics), to take the force from each landing leg and distribute it throughout the (near) hull, so that the hull experiences no extreme loads in one area. (Keep in mind the legs not only have to hold the ship up on the moon under little gravity, which might be quite easy, but also it has to carry enough load, to be keept from buckling when later covering it with regolith, if Starship should become a shelter.) So, this idea of landing horizontal with legs means more weight compared to using legs for landing vertical, because of aditional structures and then you also have the problem of somehow making them aerodinamical, or making them foldable. (which adds even more weight) So the idea that I got to possibly solve this problem and make a horizontal landing possible, is basically a big airbag like structure, that is not filled with gas, but with an expandable foam. (Well to be exact, this would also need gas to expand, but then the foam hardens and the gases escape slowly into space.) The landingbag could be stored close to the tip of the ship on the inside, behind a flap (This comes with no aerodynamic penalty compared to a naked ship, contrary to any landing leg design I have seen so far.) When the ship is in space on its way towards the moon, the flap opens, the landingbag gets pulled out by strings or some other kind of mechanism, then secured on the outside of the ship and then inflated with a chemical reaction. The foam should have enough time to harden on the way to the moon. When the Starship lands on the moon, my thinking is, that the foam will be relatively hard, but it has such properties, that it gets crushed slightly upon impact, to absorb some energy and this way also even out the forces from the rough terrain and thus keep the ships belley from being punctured, or bent, by high points, or a rock or something like that. The foam should also act as an external structural reinforcement, so the Starship has a lower chance of buckling and thus no internal structural reinforcements are needed, since the foam touches the whole belly of the ship and it should be like a quite even preassure on the hull. (The load distribution should be similar to the one experienced during reentry - wich the ship is already built for.) Here is an AI made picture, that is relatively close, to what I imagine (The foam filled bag should "hug" the shape of the ship more and there is some other minor issues with the picture, but the AI did not quite get everything I said.):
