"Miss Otis regrets..."
So, both the Japanese and the American landers did the same thing.
In the days of Apollo, a platform called “the flying bedstead”, I believe, was used to simulate and gain understanding of the landing on the Moon. At 1 Earth Gravity, it was a very stripped-down set of mostly legs - hence the name. Neil Armstrong, I believe, had to punch out of one at near 90 degrees during testing.
Without knowing, I suppose I expect that these “landers” went through none of that. When something is barely able to land on the Moon, it is very hard to simulate on Earth, except fully inside a computer.
With both the Japanese and American landers failing, I would want to look at a sudden increase in thrust just before touchdown, as the engine nozzle gets back-pressure from the surface. But, whatever it is, it probably needs to be figured out at this end, first.
They faked the 60s moon landing a whole lot better than this one. This one looks comically bad.
What a sad commentary on the state of our country...
