Gravity Constraints on Bulk Density and Igneous Intrusion at Gruithuisen Domes [#2852]
In this work, we investigate the Gruithuisen domes with new “rank minus one” gravity fields and clone fields that allow us to rigorously constrain density.

Irregular Mare Patches on the Moon: Sites of Regolith Drainage into Subsurface Voids? [#1297]
We show how irregular mare patches may form by ongoing drainage of regolith into voluminous shallow subsurface voids after collapse events tens to hundreds of million years ago.
Wagner R. V.* Robinson M. S.
Unwrapping Lunar Pits: Horizontal Views from Orbit [#1180]
We have created a method of accurately reprojecting orbital data of lunar pits into a side-looking view, and used that to evaluate layering.

Global Mapping of Dark Halo Craters on the Moon [#1412]
We mapped dark halo craters globally across the Moon to constrain cryptomaria. We found 221 craters, mostly on the nearside.

The Moon Without Mare [#2404]
Inversions of gravity and topography data are used to estimate lateral variations in mare thickness and construct maps of the Moon without mare.
