THE SLIDE MATCHES THAT SHOW THE NUT “DEPRESSION” WAS NOT ERODED BUT EXPOSED BY A RIDDEN-UP LAYER.
(Imhotep slide matches will resume in Part 45 with the orange slide)
Yellow- the perimeter of delaminated ridges that are replicated.
Green- similarly, this is a massive that has slid in the same manner as the ridges.
Red- slide tracks. Most of the larger red dots between the matches follow lines of boulders that have been strewn out along the slide track. Tellingly, the most obvious lines of boulders are at either end of the sliding matches. The smaller red dots at bottom right are a producing of the red line of boulders across the dust to the relevant matching corner of the massive. The larger red dots sitting on sets of steps at top left mark a slide that is off frame but documented in bright green in Part 29. The two parallel lines in smaller red dots next to it show two boulder slide tracks from the base of the massive that tore from the larger red dots.
A new batch of OSIRIS pictures were released today. Here are the slide matches showing that Nut is not an eroded depression as was put forward by the OSIRIS paper delineating the regions of the comet.
Nut owes its apparently dipped shape and large amount of talus to the fact that the onion layer above it slid up the head to reveal the “depression”. This was described in detail in Part 29 of this blog:
Part 29 also shows a host of matches either side of the ones shown in this Part 44 header.
