SinGAN-Based Asteroid Surface Image Generation

Journal of Database Management, 2021
While it is risky considering spacecraft constraints and unknown environment on asteroid, surface sampling is an important technique for asteroid exploration. One of the sample return missions is to seek an optimal landing site, which may be in hazardous terrain.

General Analytical Solution to the Problem of Propagation of Thermal Oscillations in Semi-bounded Solids of Various Shapes

2023 5th International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE), 2023
This paper presents a general analytical solution to the problem of propagation of thermal oscillations in semi-bounded bodies. The obtained results are useful for calculating and studying heat transfer during heat treatment of products, heat ...

Fast Trajectory Generation and Asteroid Sequence Selection in Multispacecraft for Multiasteroid Exploration

IEEE Transactions on Cybernetics, 2022
As an increasing number of asteroids are being discovered, detecting them using limited propulsion resources and time has become an urgent problem in the aerospace field. However, there is no universal fast asteroid sequence selection method that finds the trajectories for multiple low-thrust spacecraft for detecting a large number of asteroids ...

Modified Parker's Method for Gravitational Forward and Inverse Modeling Using General Polyhedral Models

Journal of Geophysical Research: Solid Earth, 2021
We propose a new modified Parker's method for efficient gravitational forward modeling and inversion using general polyhedral models. We have made several important modifications to the classical method, including: (a) The new method is now applicable to

AstroGen – Procedural Generation of Highly Detailed Asteroid Models

2018 15th International Conference on Control, Automation, Robotics and Vision (ICARCV), 2018
We present a novel algorithm, called AstroGen, to procedurally generate highly detailed and realistic 3D meshes of small celestial bodies automatically. AstroGen gains it's realism from learning surface details from real world asteroid data. We use a sphere packing-based metaball approach to represent the rough shape and a set of noise functions for ...

Compositional characterization of V-type candidate asteroids identified using the MOVIS catalogue

Monthly notices of the Royal Astronomical Society, 2019
The main objective of this work is to compositionally analyse the visible to near-infrared spectra of a total of six V-type candidates identified using the MOVIS (Y-J) versus (J-Ks) colour–colour plot and located outside the Vesta collisional family ...

Generalized Calibration of the Polarimetric Albedo Scale of Asteroids

Solar System Research, 2018
Six different calibrations of the polarimetric albedo scale of asteroids have been published so far. Each of them contains its particular random and systematic errors and yields its values of geometric albedo. On the one hand, this complicates their analysis and comparison; on the other hand, it becomes more and more difficult to decide which of the ...

Generalization of Szebehely's regions for asteroid stability

Celestial Mechanics, 1985
Using Hill's modified stability criterion in the three-dimensional restricted three-body problem with the Sun and Jupiter as the primaries, regions of stability for the semi-major axis (a) are determined. These regions are given for a range of eccentricity (e) and inc.l.ination (i), and include the effects of the remaining orbital elements.
