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.

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 ...

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 ...
