That's an article worth reading. We have frequently discussed MOND versus dark matter on this and other threads.
We are told in the article that the Cassini probe allowed us to precisely track Saturn’s orbit, but found no anomaly of the kind predicted by MOND.
The article concludes: "MOND, as presently formulated, cannot be considered a viable alternative to dark matter any more".
However, we are reminded that the standard dark matter model of cosmology isn’t perfect - there are things it struggles to explain, from the universe’s expansion rate to giant cosmic structures.
