Max has been experimenting with color enhanced imaging, and this remarkable mosaic brings to our attention many remarkable features. One reason that this false color image shows things in such a different light is that it was made from near infra-red images. The most outrageous interpretation encouraged by this view is that the dark red Aestuum pyroclastic deposits just east of Mare Insularum interupt the rays from Copernicus. Rays from Copernicus are clear as gray streamers to the west of the red deposit, and some are visible just east of the deposit. It seems totally unlikely that the pyroclastic deposits are younger than the rays from Copernicus, in fact they are thought to be about 2 billion years older. And yet the rays are not visible. Changing topics, the close in ejecta of Copernicus is conspicuously orange, which is apparently impact melt. Drop down to the golden ejecta around Herschel near bottom center - is any of that impact melt? Now jump over to Gambart A, a small bright crater south of Copernicus. Notice that it has two broad rays at right angles, is this an unusual oblique impact crater or something else? Lansberg D, at bottom, center-left, is a definite oblique impact, but you would never guess by looking at its classic simple crater morphology. Max's image will repay detailed examination - the thinness of the rays of Copernicus, the dark halo impact craters, Glushko's gray rays and so many other things - it could inspire LPOD commentaries for a month.
