New Images on Planet Four: Ridges

We’ve got some good news for your weekend. We’ve got brand new images on Planet Four: Ridges, expanding further south and east of our original area. More area covered, gives more opportunities to find unknown polygonal ridges. The more ridges we find, the better statistics we will have when we compare to other orbiter data sets to see if ground water is the main source for how these ridges form.  You can see where the search area is in comparison to our first data set below. The cyan show the footprints of the new CTX  images on the site, the magenta are the footprints of the CTX images  we had uploaded at launch. We thought the magenta area would take a year to search, so we’re thrilled that we can expand the search radius. Thanks for your time and your contributions. We really appreciated.

We’ll have some more blog posts in the coming days and weeks to talk more about this new search region.
