Planet Four Talk at the Division for Planetary Sciences

Greetings from Knoxville, Tennessee. Earlier this morning, I presented our first catalog and early results from comparing the fan directions over two Mars years at the American Astronomical Society’s Division for Planetary Science meeting.  Here’s my slides.

New Meridiani Images on Planet Four: Ridges

After a hiatus, Planet Four: Ridges is back! We’ve get the second batch of Meridiani ridges search images live on the site. We’re finding from the analysis of the previous search classifications for regular polygonal ridges, that Planet Four: Ridges volunteers can identify polygonal ridges smaller than contained in previous catalogs. We expect the project can do the same for Meridiani ridges. Dive in today at https;//ridges.planetfour.org and classify an image or two.
