This piece is not about any specific mission, even though the swirls have been imagined by orbiters.
I might be relevant since it could give an insight for some various features we discuss on this forum. Crashing comets may explain mysterious lunar swirls |

Ah, i thought you were unconvinced that the swirls were a real phenomena, maybe in the same way that many see crepuscular rays as being some kind of optical illusion. Also I was shamelessly taking a chance to mention my blog, but i do also love a chance to point out how much interesting lunar science there still is to do.
Actually i do have a further thought: Many years ago i did my phd on plasma sputterinng, incluxing sputtering of powders. It should be fairly easy to set up powder targets of simulated lunar regolith, and a sputtering atmosphere of solar wind composition and the right energy. Not trivial, but completely do-able. Vararions in magnetic field can also be aarranged, and so we could try to gauge the possible effects of soar wind on regolith and see if it explains the swirls. I expect this has been done, but i don't recall reading any papers on it... -------------------- |
