It's indeed a difficult problem and I'm not really surprised it's not solved by ESA even if they are probably extremely competent. I doubt anyone care about my opinion, but since you ask, I do notice that simulation seems to be a big part of their development. So I'm sure there has to be a way to use some kind of an evolutionary algorithm for creating descent procedures.
