Imbalanced classification applied to asteroid resonant dynamics
Published in Frontiers in Astronomy and Space Sciences
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 z 2, z 1, M1:2, and ν 6 resonances. However, one challenge when using ML to the databases produced by these studies is that...
Utilizing Helium Ion Chemistry to Derive Mixing Ratios of Heavier Neutral Species in Saturn's Equatorial Ionosphere
A surprisingly strong influx of organic-rich material into Saturn's upper atmosphere from its rings was observed during the proximal obits of the Grand Finale of the Cassini mission. Measurements by the Ion and Neutral Mass Spectrometer (INMS) gave insights into the composition of the material, but it remains to be resolved what fraction of the inf...
Comparative Study of the Adsorption of 1- and 2-Propanol on Ice by Means of Grand Canonical Monte Carlo Simulations
In this paper, we use Grand Canonical Monte Carlo simulations to compare the adsorption characteristics of two propanol isomers (1- and 2-propanol) on crystalline ice, at the temperature of 227 K (i.e., typical of the Earth’s troposphere), for which experimental data are available in the literature. The adsorption isotherms simulated for these two ...
Strength and seismic anisotropy of textured FeSi at planetary core conditions
Published in Frontiers in Earth Science
Elastic anisotropy of iron-bearing alloys and compounds can lead to a variation of seismic velocities along different directions in planetary cores. Understanding the deformation properties of candidate core-forming materials is thus necessary to reveal the details about the interior of distant planets. Silicon has been considered to be one of the ...
The future of lidar in planetary science
Published in Frontiers in Remote Sensing
Lidar has enabled advances in the knowledge of the Solar System through geophysical and atmospheric studies of the Moon, Mercury, Mars, and several asteroids. The technique will continue to be used to obtain high-precision topographic data from orbit, but new techniques on the horizon are suited to uniquely address fundamental planetary science que...
A multi-lander New Frontiers mission concept study for Enceladus: SILENUS
...
Published in Frontiers in Astronomy and Space Sciences
Enceladus, with its subsurface ocean, is amongst the top priority targets in the search for life beyond Earth. Following on discoveries from the Cassini mission that Enceladus possesses a global subsurface ocean containing salt and organic compounds, there are many unconstrained properties of the ocean and ice shell that must be investigated to fur...
Novelty detection in rover-based planetary surface images using autoencoders
Published in Frontiers in Robotics and AI
In the domain of planetary science, novelty detection is gaining attention because of the operational opportunities it offers, including annotated data products and downlink prioritization. Using a variational autoencoder (VAE), this work improves upon state-of-the-art novelty detection performance in the context of Martian exploration by > 7 % (me...
