NASA/SpaceX now proclaim the surface is 3-4 meters+ thick of Unconsolidated Regolith. So if this results in a LOT MORE DUST -
I suspect you're not understanding what this means. Are you expecting metres of dust? Should we start referring to you as Thomas Gold now? The Surveyor, and Luna, programs both showed that the surface was only several centimetres of loose material before reaching the hardpacked material. The loose material is what was blown away during landing, with visible halos still existing to this date at each landing site, and why all photos of the area underneath the LMs show them to be free of loose material, only showing the hardpacked surface, with the loose material returning before the landing pads are reached, as was expected.
For what other reason would they NOT be sharing ANY good photos or footage from the lander?? How the hell did they not know their horizontal velocity? Way too much dust - would explain it.
You mean the lander that had it's main radar fail before even reaching the moon and required new software to be written and uploaded so it could attempt to use equipment that wasn't supposed to be used as a landing radar? Gee, I wonder why it didn't end up landing correctly.
And then, since it landed in a poor orientation, the power didn't last as long as was expected, not was communication as easily established. And, as an added unfortunate bonus, the cube-sat camera that had been built by university students failed to transmit back to the lander. For all we know, it's got a wonderful collection of photos, it just didn't want to share them.
And radar isn't typically blocked by dust, given most dust particles are, on average, about 1,000 times smaller than the wavelengths used.
