The company [that helped build the rover] is perhaps most famous for originally creating the Transformers, the alien robots that can disguise themselves as machines
Doh! Well, at least next time they'll know they should design it so that the engines don't fall off. Maybe add some tape and push it harder against the frame for a few seconds so it knows it's meant to remain there.
I'm willing to let that one pass just because it's something people have gotten so used to here that it's likely taken for granted by many. I'm guessing that line got far more, "oh right, duh" reactions than, "wait what!?" ones.
I personally think this should be one of our priorities while planning a permanent base. If we start with a constellation of gps/communications satellites, it will make everything else so much easier.
So at this point, we've been there in person. We fully understand the atmosphere, the gravity, and the topology. We have laser range finding, lidar, stereoscopic vision. Trajectory and velocity are both more or less solved problems by this point, right?... Right? There's only 2.7 seconds of light delay. How have we screwed up so many landings?
I'm not saying it's easy, or that I could do better, but multi national attempts, how many billions of dollars, surely we have to have enough tech to do this with proper fail safes by now.
Because of the "more or less" part of your post. Oversimplifying things is nice for a quick explanation, but physics don't care about your simplified model once you get up there, gravity isn't completely uniform, random space stuff sends you slightly off your path, and your target move in a mostly (but not 100%) predictable way, around your planet.
I wasn't aware the gravity on the moon wasn't mostly uniform. I've not heard that before. Any particular reason image processing couldn't be used to keep the down side down? Or when the previous lander crashed thinking it was many KM higher but it didn't have backups for each sensor type? I've been following along and many of these seem to be preventable issues when it comes to the price of a launch.
For that matter, light delay to manually change system parameters seems to be reasonable.
