The present paper studies the powered Swing-By maneuver when performed in an elliptical
system of primaries. It means that there is a spacecraft travelling in a system governed by the …

The study of aero-gravity-assisted maneuvers around Venus is the focus of the present
paper. These are maneuvers that combine the passage by the gravity field of the planet with …

A Gravity-Assist maneuver is used to reduce fuel consumption and/or trip times in
interplanetary missions. It is based in a close approach of a spacecraft to a celestial body …

The present paper surveys the more recent techniques related to the swing-by maneuver,
where a spacecraft changes its energy and angular momentum by passing close to celestial …

Abstract The Swing-By maneuver is a technique used in many space mission to modify the
trajectory of a spacecraft. The most usual goal is to increase the energy of the spacecraft, but …

Thse powered aero-gravity-assist is an orbital maneuver that combines three basic
components: a gravity-assist with a passage by the atmosphere of the planet during the …

In a swing-by maneuver, the variation of energy of the spacecraft is controlled by the angle,
velocity, and distance of approach. These parameters are defined by the incoming trajectory …

In this work, it is shown how a spacecraft equipped with a thrust and subjected to a drag
force can be bounded at specific altitudes as function of the parameters of the thrust. It is …

Abstract Studies related to Celestial Mechanics started long ago, and it is one of the oldest
fields in Astronomy. It started to try to explain the motions of the stars in the sky, in particular …
