Orbital flybys have been extensively studied for spacecraft missions, resulting in effective
mathematical and physical models. However, these models' applicability to natural …

This work proposes a numerical investigation for periodic orbits in the restricted three-body
problem to observe the smaller primary of the system. Periodic orbits are very important for …

The gravity assist or flyby is investigated by analysing the inertial energy of a test particle in
the elliptic restricted three-body problem (ERTBP), where two primary bodies are moving in …

In this paper, the powered swing-by is investigated in the planar elliptic restricted three-body
problem. A calculation method of the energy variation for the one-impulse powered swing-by …

THE gravity assist (GA) is a classical technique to change the path and energy of a
spacecraft flying close to a celestial body, which only needs gravitational forces from …

This work studies transfer between non-coplanar circular orbits around Earth with the space
vehicle performing a powered lunar flyby maneuver. The complete transfer trajectory is …

In this paper, we investigate flyby trajectories combining powered gravity assist (PGA) with
aerogravity assist (AGA) in the planar elliptic restricted three-body problem (PERTBP). The …

In this paper, the angular momentum of the test particle during the flyby in the spatial elliptic
restricted three-body problem (ERTBP) is investigated. We focus on the flyby around the …

THE swing-by is an efficient technique to change the path and energy of a spacecraft flying
close to a celestial body, and it has been widely applied in many interplanetary missions. A …

The powered swing-by maneuver is described by the parameters that define the orbit of the
spacecraft and the ones that define the impulse applied. In this case the impulse is applied …
