The Cumulation of Debris Clouds around a Fast-rotating Asteroid

open access: yesThe Astrophysical Journal
The rotational mass loss has been realized to be a prevalent mechanism to produce low-speed debris near the asteroid, and the size composition of the asteroid’s surface regolith has been closely measured by in situ explorations.

Bio‐Inspired Swarm Robotics Design for Mine Automation

open access: yesNatural Sciences, Volume 6, Issue 2, April 2026.
Ants demonstrate tandem running for cooperative haulage, and honeybees use memory‐based routes between hive and flowers. These behaviours inspire autonomous haulage robots in open‐pit mines to achieve efficient scan‐plan‐retrieve ore transport, replacing small haulage robots with large mining trucks.

Rotationally Resolved Mid-infrared Spectroscopy of (16) Psyche

open access: yesThe Planetary Science Journal
Asteroid (16) Psyche is theorized to be an exposed iron core of a primordial asteroid and is the target of the upcoming NASA Psyche mission. Recent observations of Psyche identified the presence of rotational heterogeneity, a fine-grained regolith ...

Multi-criteria comparison among several mitigation strategies for dangerous near Earth objects

open access: yes, 2009
In this paper a comparative assessment of the effectiveness of different deviation methods for Near Earth Objects is presented. Specifically, solar collector, nuclear interceptor, kinetic impactor, low-thrust propulsion, mass driver and gravity tug are ...

Deciphering the “Missing Xenon Paradox” in Celestial Bodies: A Multifaceted Perspective Toward Demystifying This Enigma

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

Statistics of asteroid axis rotation

open access: yes, 1991
Показано, что по зависимостям скорости осевого вращения от диаметра и удельного углового момента от массы, астероиды делятся на три группы в соответствии с разной степенью влияния столкновительной эволюции на параметры, их осевого вращения.

On the asteroid rotation

open access: yes, 1988
Как один из возможных механизмов приобретения астероидами углового вращения рассматриваются упруговязкне соударения между телами, покрытыми толстой реголитовой оболочкой.

An L1 positioned dust cloud as an effective method of space-based geoengineering

open access: yes, 2010
In this paper a method of geoengineering is proposed involving clouds of dust placed in the vicinity of the L1 point as an alternative to the use of thin film reflectors.

Dynamic 3D Simulation of Surface Charging on Rotating Asteroids

open access: yesThe Astrophysical Journal
The surface-charging phenomenon of asteroids, mainly resulting from solar wind plasma and solar radiation, has been extensively studied. However, the influence of the asteroid’s rotation on surface charging is not yet fully understood.

Nonextensive distributions of asteroid rotation periods and diameters

open access: yes, 2012
Context. We investigate the distribution of asteroid rotation periods from different regions of the solar system and diameter distributions of near-Earth asteroids (NEAs). Aims. We aim to verify if nonextensive statistics satisfactorily describes
