PLANETARY SCIENCE INSTITUTE INDIVIDUAL ANNUAL REPORT

Calendar Year 2017

I. Ongoing Research Scott received new funding (3 years) in May 2015 for his proposal – “Geologic Mapping of Ceres: Distribution and Timing of Volatile- and Ice-Driven Processes on the Main Belt Dwarf Planet“ – selected for the Dawn at Ceres Guest Investigator Program; the project is currently in its second year of funding. Scott and Co-Investigators D. Crown, A. Yingst, and D. Berman are assisting the Dawn Science Team with the global geologic mapping of Ceres, and are contributing to the quad-scale mapping of Ceres. Our team is responsible for publication and archiving of the global geologic map at the High-Altitude Mapping Orbit (HAMO) scale. The map (shown below in Figure 1) was completed in the summer of Year 3, and the manuscript is currently being written, and we hope to submit it to a journal by the end of Year 3.

Figure 1. Global geologic map of Ceres based on Dawn Framing Camera images acquired during the HAMO phase of its mission. At this scale, the map shows a surface dominated by cratered terrain (brown unit), smooth plains (blue unit), materials of the Urvara and Yalode impacts (lower right), and crater materials. In September of 2017, Scott began his first NCE of the PG&G proposal entitiled “Geologic History of the Upper Dao and Niger Valles, Northeastern Hellas Region of Mars”. This proposal provides 4 years of funding to map three quadrangles along the northeastern rim of Hellas basin (Figure 1). Team members include Dr. David Crown (CoI, PSI), Dr. Joseph Michalski (CoI, PSI), Frank Chuang (CoI, PSI), Dr. Katherine Price Blount (Collaborator, Texas A&M), and Dr. Leslie Bleamaster (Collaborator, Trinity University)

Figure 2. Current geologic map of the 3-quad Upper Dao and Niger Valles map area; THEMIS dTIR mosaic (100 m/pixel) is base. The map area includes sections of Dao and Niger Valles (teal units), the channeled flanks of Hadriacus Mons (orange unit), channeled plains (light green unit), the terminus of the Tyrrhenus Mons flow field (red unit), and remnants of highlands (grey) and impact craters (yellow and dark green).

Scott is a Co-Investigator on an MDAP headed by Dr. Ross Irwin entitled “Exposed Stratigraphy on the Floors of Noachian Impact Craters on Mars”, which was completed in 2016. This project is looking at the floors of several Martian highland impact craters and evaluating the nature of layered deposits on their floors and the histories of emplacement of these materials. This research is being conducted to determine if there are any similarities in the timing and/or style of deposition. The manuscript submitted for publication by Dr. Irwin is currently in review.

Mapping of the lunar South Pole Quadrangle (LQ-30) of the Moon (Figure 3, next page) is complete. Scott, with Co-Is Daniel Berman and Noah Petro, and Collaborator Aileen Yingst, will write up the map text, develop the Description of Map Units (DoMU) and Correlation of Map Units (CoMU), and submit the map to the USGS for review. This project completed its second NCE when all funds were expended.

New projects that began in 2016 include the geologic remapping of Vesta, lead by Dr. R. A. Yingst (Mest is a Co-Investigator), and geologic mapping of the Borealis Quadrangle (H-1) of Mercury lead by Dr. L. Ostrach (USGS Flagstaff) for which Mest is a Co-Investigator.
