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 ...

Mirror formation control in the vicinity of an asteroid [PDF]
, 2008 Two strategies are presented for the positioning and control of a spacecraft formation designed to focus sunlight onto a point on the surface of asteroid, thereby sublimating the material and ejecting debris creating thrust.

An Efficient Numerical Approach to Modeling the Effects of Particle Shape on Rubble-pile Dynamics
The Planetary Science Journal, 2023 We present an approach for the inclusion of nonspherical constituents in high-resolution N -body discrete element method (DEM) simulations. We use aggregates composed of bonded spheres to model nonspherical components.

(523599) 2003 RM: The Asteroid that Wanted to be a Comet
The Planetary Science Journal, 2023 We report a statistically significant detection of nongravitational acceleration on the subkilometer near-Earth asteroid (523599) 2003 RM. Due to its orbit, 2003 RM experiences favorable observing apparitions every 5 yr.

Secular evolution of asteroid families: the role of Ceres
, 2015 We consider the role of the dwarf planet Ceres on the secular dynamics of the asteroid main belt. Specifically, we examine the post impact evolution of asteroid families due to the interaction of their members with the linear nodal secular resonance with

Stereophotoclinometry for OSIRIS-REx Spacecraft Navigation
The Planetary Science Journal, 2023 We summarize a decade of effort by the Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS-REx) mission team to build up the unique capabilities, processes, and procedures required to accomplish the ...

Characterizing the original ejection velocity field of the Koronis family
, 2016 An asteroid family forms as a result of a collision between an impactor and a parent body. The fragments with ejection speeds higher than the escape velocity from the parent body can escape its gravitational pull.

Chirikov Diffusion in the Asteroidal Three-Body Resonance (5,-2,-2) [PDF]
, 2010 The theory of diffusion in many-dimensional Hamiltonian system is applied to asteroidal dynamics. The general formulations developed by Chirikov is applied to the Nesvorn\'{y}-Morbidelli analytic model of three-body (three-orbit) mean-motion resonances ...

Advanced Materials, EarlyView.All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.
