Journal of Field Robotics, EarlyView.ABSTRACT Planetary exploration is rapidly gaining importance within the space research community. Autonomous locomotion of rovers requires consideration of several mobility aspects to ensure safety, including avoiding hazardous areas that can cause the robot to become immobilized in soft soil or damaged in sharp terrains.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

High-resolution topography of Gusev crater using CTX data (Mars).
GeogacetaHigh-resolution Digital Terrain Models (DTMs) of Mars are both limited and crucial for studying surface processes. The available DTMs generated from Mars Orbiter Laser Altimeter (MOLA) and High-Resolution Stereo Camera (HRSC) data offer limited ...

A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers
River Research and Applications, EarlyView.ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates
The Economic Journal, EarlyView., 2018 The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Ancient fluvial processes in the equatorial highlands of Mars [PDF]
Martian highland craters typically lack ejecta deposits, have no noticeable rim, and are flat floored. In addition, crater size frequency distribution curves show that highland craters have depleted populations less than 20 km in diameter.

Solvent‐Induced Surface Morphology Probed by NP‐SIMS
Surface and Interface Analysis, EarlyView.ABSTRACT Surface morphology, that is, roughness and molecular arrangement, is known to have an impact on secondary ion mass spectra. The present study examines this issue using nanoprojectile secondary ion mass spectrometry (NP‐SIMS). NP‐SIMS involves bombarding the analyte with individual nanoparticles resolved in space and time and recording the ...

Paradigm lost: Venus crater depths and the role of gravity in crater modification [PDF]
Previous to Magellan, a convincing case had been assembled that predicted that complex impact craters on Venus were considerably shallower than their counterparts on Mars, Mercury, the Moon, and perhaps even Earth.

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review
SmartBot, EarlyView.Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.
