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.

Heliotropic dust rings for Earth climate engineering

, 2013
This paper examines the concept of a Sun-pointing elliptical 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 J(2) oblateness ...

Dust measurements with the Mars Dust Counter on board Nozomi (PLANET-B)

Earth, Planets and Space
Nozomi was Japan’s first space mission to Mars, launched on 3 July 1998 UT. It was equipped with the Mars Dust Counter (MDC) which was an impact ionisation dust detector.

Meteorites and cosmic dust: Interstellar heritage and nebular processes in the early solar system

EPJ Web of Conferences, 2012
Small solar system bodies like asteroids and comets have escaped planetary accretion. They are the oldest and best preserved witnesses of the formation of the solar system.

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

Journal of Field Robotics, EarlyView.
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

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

SmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

Updating the Electrostatic Model for Dust Impact Detection with Antenna Instruments

The Astrophysical Journal
Antenna instruments deployed in space are known to be sensitive to dust impacts, and the detected signals can be used to characterize the dust populations within the solar system.

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 ...
