Gradient-index Solar Sail and its Optimal Orbital Control
Shahin Firuzi, Yu Song, Shengping Gong
Solar sails with the capability of generating a tangential radiation pressure at the sun-pointing attitude, such as refractive sails can provide more efficient methods for attitude…
All-dielectric Tailored-index Index-matched Arbitrary Waveguides based on Transformation Optics
Shahin Firuzi, Shengping Gong
Transformation optics based on conformal mapping (CM) technique provides a practical approach to designing arbitrary-shaped all-dielectric devices. However, CM may result in large…
Long-range optical pulling force device based on vortex beams and transformation optics
Shahin Firuzi, Shengping Gong
In this work a method for generating a long-range optical pulling force is presented which is realized by utilizing a vortex beam and a device designed based on transformation opti…
On the Instability of Saturn's Hypothetical Retrograde Co-orbitals
Yukun Huang, Miao Li, Junfeng Li +1
We find an interesting fact that fictitious retrograde co-orbitals of Saturn, or small bodies inside the retrograde 1:1 resonance with Saturn, are highly unstable in our numerical…
Solar-Sail Trajectory Design for Multiple Near Earth Asteroid Exploration Based on Deep Neural Networks
Yu Song, Shengping Gong
In the preliminary trajectory design of the multi-target rendezvous problem, a model that can quickly estimate the cost of the orbital transfer is essential. The estimation of the…
Solar-Sail Deep Space Trajectory Optimization Using Successive Convex Programming
Yu Song, Shengping Gong
This paper presents a novel methodology for solving the time-optimal trajectory optimization problem for interplanetary solar-sail missions using successive convex programming. Bas…
Kozai-Lidov Mechanism inside Retrograde Mean Motion Resonances
Yukun Huang, Miao Li, Junfeng Li +1
As the discoveries of more minor bodies in retrograde resonances with giant planets, such as 2015 BZ509 and 2006 RJ2, our curiosity about the Kozai-Lidov dynamics inside the retrog…
Centaurs potentially in retrograde co-orbit resonance with Saturn
Miao Li, Yukun Huang, Shengping Gong
Aims. 2015 BZ509 is the first asteroid confirmed to be in retrograde co-orbit resonance (or 1/-1 resonance) with the giant planets in the solar system. While Saturn is the only gia…
Dynamic portrait of the retrograde 1:1 mean motion resonance
Yukun Huang, Miao Li, Junfeng Li +1
Asteroids in mean motion resonances with giant planets are common in the solar system, but it was not until recently that several asteroids in retrograde mean motion resonances wit…
Satellite capture mechanism in a sun-planet-binary four-body system
Shengping Gong, Miao Li
This paper studies the binary disruption problem and asteroid capture mechanism in a sun-planet-binary four-body system. Firstly, the binary disruption condition is studied and the…
Bifurcation of equilibrium points in the potential field of asteroid 101955 Bennu
Xianyu Wang, Junfeng Li, Shengping Gong
The stability and topological structure of equilibrium points in the potential field of the asteroid 101955 Bennu have been investigated with a variable density and rotation period…
A method for classifying orbits near asteroids
Xianyu Wang, Shengping Gong, Junfeng Li
A method for classifying orbits near asteroids under a polyhedral gravitational field is presented, and may serve as a valuable reference for spacecraft orbit design for asteroid e…
Analysis of the Potential Field and Equilibrium Points of Irregular-shaped Minor Celestial Bodies
Xianyu Wang, Yu Jiang, Shengping Gong
The equilibrium points of the gravitational potential field of minor celestial bodies, including asteroids, comets, and irregular satellites of planets, are studied. In order to un…
Utilization of H-reversal Trajectory of Solar Sail for Asteroid Deflection
Shengping Gong, Junfeng Li, Xiangyuan Zeng
Near Earth Asteroids have a possibility of impacting with the Earth and always have a thread on the Earth. This paper proposes a way of changing the trajectory of the asteroid to a…
New applications of the H-reversal trajectory using solar sails
Xiangyuan Zeng, Hexi Baoyin, Junfeng Li +1
Advanced solar sailing has been an increasingly attractive propulsion system for highly non-Keplerian orbits. Three new applications of the orbital angular momentum reversal (H-rev…
