SinGAN-Based Asteroid Surface Image Generation
Journal of Database Management, 2021While 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.

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 ...

AstroGen – Procedural Generation of Highly Detailed Asteroid Models
2018 15th International Conference on Control, Automation, Robotics and Vision (ICARCV), 2018We 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 ...

Automated Computation of General Perturbations for the Flora Asteroidal Group
Publications of the Astronomical Society of Australia, 1991AbstractThe general perturbations of the asteroids of the Flora group (975″ < n < 1150″, n - the mean daily motion) due to Jupiter have been automatically computed on an IBM 4341 computer with the Hansen method by manipulating Broucke’s Symbolic Poisson Series Processor, and the results have been compared with that computed previously with the ...

In computer graphics there exist mainly two ways to represent 3D shapes: implicit methods and explicit methods. The explicit method is quite obvious which uses triangle meshes to represent any shape precisely, while the distinct disadvantage is hard to compute interactions between triangle meshes which is very important in lots of graphic applications.

Generalization of Szebehely's regions for asteroid stability
Celestial Mechanics, 1985Summary: 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 inclination (i), and include the effects of the remaining orbital elements. This
