Incorporating Physical Knowledge Into Machine Learning for Planetary Space Physics
Frontiers in Astronomy and Space Sciences, 2020 Recent improvements in data collection volume from planetary and space physics missions have allowed the application of novel data science techniques. The Cassini mission for example collected over 600 gigabytes of scientific data from 2004 to 2017. This

Imbalanced classification applied to asteroid resonant dynamics
Frontiers in Astronomy and Space Sciences, 2023 Introduction: Machine learning (ML) applications for studying asteroid resonant dynamics are a relatively new field of study. Results from several different approaches are currently available for asteroids interacting with the z2, z1, M1:2, and ν6 ...

Factoring Origin of Life Hypotheses into the Search for Life in the Solar System and Beyond
Life, 2020 Two widely-cited alternative hypotheses propose geological localities and biochemical mechanisms for life’s origins. The first states that chemical energy available in submarine hydrothermal vents supported the formation of organic compounds and ...

Landforms Associated With the Aspect‐Controlled Exhumation of Crater‐Filling Alluvial Strata on Mars
Geophysical Research Letters, 2023 Fluvial channel belts, the deposits accumulated in rivers surrounded by floodplain deposits, are sensitive environmental recorders. Across Mars, wind has exposed ancient channel belts via the preferential erosion of floodplain strata, creating landforms ...

Electron Energization by Ion Density Enhancement in the Martian Magnetotail—MAVEN Observations
The Astrophysical JournalIt has been long observed at Mars that electron fluxes are enhanced during the tail current sheet crossings, of which the cause is not well understood. We use a novel approach to reveal one of the electron energization mechanisms with observations from ...
