Passive Sorting of Asteroid Material Using Solar Radiation Pressure [PDF]
Journal of Guidance, Control, and Dynamics, 2014 Understanding dust dynamics in the vicinity of asteroids is key for future science missions and, in the long-term, for asteroid exploitation. This paper analyzes the feasibility of manipulating asteroid material by means of solar radiation pressure. A novel method is proposed for passively sorting material as a function of its grain size or density ...

Orbital Dynamics of "Smart-Dust" Devices with Solar Radiation Pressure and Drag [PDF]
Journal of Guidance, Control, and Dynamics, 2011 This paper investigates how perturbations due to asymmetric solar radiation pressure, in the presence of Earth shadow, and atmospheric drag can be balanced to obtain long-lived Earth centred orbits for swarms of micro-scale 'smart dust' devices, without the use of active control.

A Study of the Influence of Environmental Factors on Water–Heat Exchange Process in Alpine Wetlands
Atmosphere, 2023 Wetlands, which are composed of soil, vegetation and water, have sufficient water supply and are sensitive to climate change. This study analyzes the coupling degree between wetlands and atmosphere and discusses the influence of environmental factors ...

Solar radiation pressure on (99942) Apophis [PDF]
Icarus, 2011 Abstract Near-Earth asteroid (99942) Apophis currently resides among the top positions on the list of objects with small, yet non-zero impact probability with the Earth. For that reason an unusual observational and theoretical effort has been dedicated to precisely characterize its future orbit.

Solar radiation pressure resonances in Low Earth Orbits [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 The aim of this work is to highlight the crucial role that orbital resonances associated with solar radiation pressure can have in Low Earth Orbit. We review the corresponding literature, and provide an analytical tool to estimate the maximum eccentricity which can be achieved for well-defined initial conditions.

Theory of radiation pressure on a diffractive solar sail
Journal of the Optical Society of America B, 2022 Solar sails propelled by radiation pressure enable space missions that cannot be achieved using chemical rockets alone. Significant in-space propulsion for missions such as a solar polar orbiter may be achieved with a sail that deviates sunlight at a large average angular direction.

Theoretical and numerical studies on multi‐physical issues of space parabolic membrane antennas
IET Microwaves, Antennas & Propagation, 2021 Front‐fed parabolic reflectors are among the most commonly used antennas in the industry. While in spaceborne applications, membrane reflectors are very promising due to their lightweight and foldable features.
