Using visualisations to develop skills in astrodynamics [PDF]

open access: greenEuropean Journal of Engineering Education, 2020
Learning about the geometry and kinematics of bodies and their trajectories through space (or ‘astrodynamics’) is challenging due to its three-dimensional nature. To address this, the University of Bristol have developed simulation exercises for students

Mubody, an astrodynamics open-source Python library focused on libration points [PDF]

open access: hybrid4th Symposium on Space Educational Activities, 2022
Mubody is an astrodynamics open-source Python library focused on the libration points. Such points result from the equilibrium of the gravitational forces between two massive bodies as the Sun and Earth, for example.

Parallel Evaluation of Chebyshev Approximations: Applications in Astrodynamics [PDF]

open access: hybridThe Journal of the astronautical sciences, 2022
Approximations based on Chebyshev polynomials have several astrodynamic applications. The performance of these approximations can be improved by parallel implementations exploiting parallel architectures, such as OpenMP and CUDA.
