On the moon, the gravitational pull is six times weaker than on Earth. For decades, researchers testing rovers have accounted for that difference in gravity by creating a prototype that is a sixth of the mass of the actual rover. They test these lightweight rovers in deserts, observing how it moves across sand to gain insights into how it would perform on the moon.
It turns out, however, that this standard testing approach overlooked a seemingly inconsequential detail: the pull of Earth's gravity on the desert sand.

It just goes to show you, you can have whole teams of NASA scientists on a project, but there's still going to be some factor they didn't think of when the rubber meets the road.
Surely you mean 'when the zinc-coated steel meets the sand'

*When the comment meets the feddiverse
No, I mean the rubber of the trolley to the launchpad, and don't call me Shirley.
Was it a critical flaw or was it simply ignored despite being well known?
I remember watching footage of the LRV's they used on the Apollo missions and thinking that the "sand" looked really lightweight. I also remember reading that one of the complaints from those missions was that the moon dust was really fine and seemed to get into everything.
I have a feeling someone who worked at NASA proposed this as an issue and leadership ignored their concerns.
So basically astronauts hate the moon dust. It's lightweight and fine and it gets everywhere.
Yeah Iβve also thought about this before and Iβm pretty sure it was even covered in that recent movie about faking the moon landing. It could just have been missed though, everyone else assumed it was covered years ago and so no one thought to recheck.
