Astrogeology Invites the Community to Visit!
As part of Flagstaff’s popular Festival of Science events, the USGS Flagstaff Science Campus recently hosted a Campus-Wide Open House. The Astrogeology Science Center (ASC), Southwest Biological Science Center, and Arizona Water Science Center all provided a variety of activities for the approximately 225 happy visitors who attended.
Sols 2551-2552: Analyzing the Glen Etive 2 drill sample
Sols 2538-2539: An Intermission Filled with Remote Sensing
Today started off with the news that yestersol’s plan did not fully complete. There was an issue in the set of planned SAM activities that resulted in those activities not completing. While we diagnose the issue, we are taking a break from drill activities and filling the plan with lots of remote science.

Report from the Ice and Climate Evolution Science Analysis group (ICE-SAG)
This document is the final report of the Ice and Climate Evolution Science Analysis Group (ICESAG) that was formed by the Mars Exploration Program Analysis Group (MEPAG) as part of its preparations for the upcoming NASA Planetary Science Decadal Survey for 2023 through 2032 (see §1). Through telecons, one face-to-face meeting, and discussions with...
Putzig, Than; Diniega, Serina; Dundas, Colin M.; Titus, Timothy N. Active boulder movement at high Martian latitudes
Lobate stony landforms occur on steep slopes at high latitudes on Mars. We demonstrate active boulder movement at seven such sites. Sub-meter-scale boulders frequently move distances of a few meters. The movement is concentrated in the vicinity of the lobate landforms but also occurs on other slopes. This provides evidence for a new, common style...
Dundas, Colin M.; Mellon, Michael T.; Conway, Susan J.; Gastineau, Renaldo Formation of pedestalled, relict lakes on the McMurdo Ice Shelf, Antarctica
Surface debris covers much of the western portion of the McMurdo Ice Shelf and has a strong influence on the local surface albedo and energy balance. Differential ablation between debris-covered and debris-free areas creates an unusual heterogeneous surface of topographically low, high-ablation, and topographically raised (‘pedestalled’), low-...
