Galactic planetary science [PDF]
Planetary science beyond the boundaries of our Solar System is today in its infancy. Until a couple of decades ago, the detailed investigation of the planetary properties was restricted to objects orbiting inside the Kuiper Belt. Today, we cannot ignore that the number of known planets has increased by two orders of magnitude nor that these planets ...

Review of Venusian and Martian ionospheres
The launch of Tianwen 1 marks the brand-new stage of the deep space exploration of China, which calls for the foundation of planetary science education in China. In planetary science, the ionosphere is considered to be the region of an atmosphere where a

Incorporating Physical Knowledge Into Machine Learning for Planetary Space Physics
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
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
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
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 ...

Thirty years ago, most important planetary research could be found within a modest monthly journal, an annual conference proceedings, and a smattering of articles in AGU and other publications. Since then, planetary science has become an enormously successful enterprise; its literature is now published in several dedicated journals and forms a major ...

Electron Energization by Ion Density Enhancement in the Martian Magnetotail—MAVEN Observations
It 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 ...
