Just curious, has anyone gone spelunking in the Magellan SAR EDR (raw) dataset?
https://pds-imaging.jpl.nasa.gov/data/magellan/edr/ Looks like a set of 9-track mag tapes were copied to CD-ROMs for preservation, and at some point the CD files were put online in PDS. In starting to look at it, I realized that lack of knowledge of mag tape volume/label/file/record structure and terminology may impede younger explorers of this dataset. |

For a little visual aid here is 3D view of the Maat Moons rendered at 4x vertical exaggeration , looking towards southeast, the area from the article is in the front. The Magellan DEM is really rough and blocky, producing kind of an artificial bench that is not really there, but it could possibly be a downward movement of lava that we are seeing. Unfortunately it will be a long wait until we get 250m/pixel DEM planned by the VERITAS mission for a better view. |

And after a few years' more wait, EnVision will provide 60m spatial resolution topography.
However, if there was any significant change during just a year of Magellan's mission, it seems likely that some more significant change will be there to be discovered after ~35 years, unless, improbably, there's just one location on Venus where change occurs. |
