Published in 2017 at "Astrophysics and Space Science"

DOI: 10.1007/s10509-017-3087-y

Abstract: This paper analyzes the dynamical evolution of satellites formed by two masses connected by a cable—tethered satellites. We derive the Lagrangian equations of motion in the neighborhood of the collinear equilibrium points, especially for the… read more here.

Published in 2019 at "Astrophysics and Space Science"

DOI: 10.1007/s10509-019-3532-1

Abstract: We studied Earth–Moon transfer trajectories in the circular restricted three-body problem (CRTBP) from the viewpoint of families and considered their applications in transferring a spacecraft from the Earth to periodic orbits around Sun–Earth libration point… read more here.

Published in 2021 at "Acta Astronautica"

DOI: 10.1016/j.actaastro.2021.05.019

Abstract: Abstract The stable near rectilinear halo orbits (NRHOs) and distant retrograde orbits (DROs) are both considered as potential parking orbits for cis-lunar stations. Transfer orbits between NRHOs and DROs can promote the exploitation of their… read more here.

Published in 2017 at "Advances in Space Research"

DOI: 10.1016/j.asr.2017.07.046

Abstract: Abstract In this paper, we show a low energy Earth–Moon transfer in the context of the Sun–Earth–Moon–spacecraft 4-body system. We consider the 4-body system as the coupled system of the Sun–Earth–spacecraft 3-body system perturbed by… read more here.

Published in 2021 at "Icarus"

DOI: 10.1016/j.icarus.2020.114110

Abstract: Abstract Lunar impact crater chronologies have been developed by combining carefully measured crater densities of lunar terrains with radiometric ages provided by returned samples. However, due to the sparse coverage of the samples during the… read more here.
