I really don’t understand the tall moon lander strategy… I mean, if you’re going to design it with a high center of gravity, then design it to fall over… Just use two landing legs instead of four, to ensure it falls over on the correct side. Then you put the solar panels on the side, so that when it topples over they’re facing up.

I’ve literally done this in Kerbal space program, it’s a pretty reliable landing system if your probe is tall.
