Sinuous collapse chains and skylights in lunar and Martian volcanic regions have often
been interpreted as collapsed lava tubes (also known as pyroducts). This hypothesis has …

The NASA Ames Stereo Pipeline is a suite of free and open source automated geodesy and
stereogrammetry tools designed for processing stereo images captured from satellites …

We present an improved lunar digital elevation model (DEM) covering latitudes within±60°,
at a horizontal resolution of 512 pixels per degree (∼ 60 m at the equator) and a typical …

We present results from geomorphic map** and visible to near‐infrared spectral analyses
of the Jezero crater paleolake basin and its associated watershed. The goal of this study is …

We examine the stratigraphic architecture and mineralogy of the western fan deposit in the
Jezero crater paleolake on Mars to reassess whether this fan formed as a delta in a standing …

The Jezero crater open-basin lake contains two well-exposed fluvial sedimentary deposits
formed early in martian history. Here, we examine the geometry and architecture of the …

To evaluate the topography of the surface within the InSight candidate landing ellipses, we
generated Digital Terrain Models (DTMs) at lander scales and those appropriate for entry …

Aeolis Dorsa, a large sedimentary basin on Mars, contains an array of fluvially dominated
sedimentary deposits. These deposits preserve a record of fluvial erosion and deposition …

The glaciers of the Franz Josef Land (FJL) archipelago in the Russian Arctic are subjected to
rapidly-warming temperatures but are small contributors to sea level. We analyze ice surface …

Recurring slope lineae (RSL) are dark linear features on the surface of Mars that advance
incrementally downslope, fading and re-growing annually. Numerous hypotheses have …
