Eccentric Dust Ring in the IRS 48 Transition Disk

The Astrophysical Journal Letters, 2023
Crescent-shaped structures in transition disks hold the key to studying the putative companions to the central stars. The dust dynamics, especially that of different grain sizes, is important to understanding the role of pressure bumps in planet ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

The Scientific Need for a Dedicated Interplanetary Dust Instrument at Mars [PDF]

, 2021
International audienceInterplanetary dust is a scientifically important constituent of the Solar System that consists of material shed by asteroids, comets, and other airless bodies.

Geo-engineering using dust grains in heliotropic elliptical orbits [PDF]

, 2011
This paper examines the concept of a Saturn-like Earth ring comprised of dust grains to offset global warming. A new family of non-Keplerian periodic orbits, under the effects of solar radiation pressure and the Earth’s oblateness J2 perturbation, is ...

Optimizing Hybrid Wind–Solar Systems in Barren Land Under Constraints Imposed by Atmospheric Aerosols

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract By using a solar photovoltaic (PV) performance model and applying it to global data from 2000 to 2022, we demonstrated that although the net impact of aerosols on power generation was negative, this loss was almost entirely driven by soiling of panel surfaces and could be mitigated by developing an appropriate cleaning regime.

Seasonal Variation of Micrometeoroid Impacts and Dust Clouds around Saturn’s Rings

The Planetary Science Journal
The Saturnian rings are continuously bombarded by interplanetary dust, which delivers exogenic material, generates impact ejecta, and contributes to the dynamical and compositional evolution of the rings.

Sources of Interplanetary Dust [PDF]

International Astronomical Union Colloquium, 1996
AbstractAsteroids, comets and interstellar dust are possible sources of the particles that constitute the dust in the inner solar system. Each of these components gives rise to particular, characteristic features, the amplitudes of which can be used to estimate the size of the associated source.

Active Dust Devils in the Rosalind Franklin Rover Landing Site in Oxia Planum, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Rosalind Franklin rover will land in Oxia Planum, Mars, in the second half of 2030. The mission relies on solar arrays to provide electrical power to the rover, so knowledge about dust‐clearing rates is important for science operations.

Porosity of serially sectioned interplanetary dust particles

, 1987
The application of epoxy embedding and microtomy to individual chondritic interplanetary dust particles (lOP's)(Bradley and Brownlee, 1986a) provides not only higher precision in thin-film elemental analyses (Bradley and Brownlee, 19861:1), but also ...

A Rotational Disruption Crisis for Zodiacal Dust

The Astrophysical Journal Letters
A systematic torque from anisotropic radiation can rapidly spin up irregular grains to the point of breakup. We apply the standard theory of rotational disruption from radiative torques to solar system grains, finding that grains with radii ∼0.03–3 μ m ...
