A central problem in space mission planning is determining the trajectory that accomplishes
all mission goals while minimizing the amount of required to execute all maneuvers. Due to …

In this paper, a collision avoidance maneuver was sought for low Earth orbit (LEO) and
geostationary Earth orbit (GEO) satellites maintained in a keeping area. A genetic algorithm …

The Republic of Korea plans to launch a lunar orbiter and lander by 2020. There are several
ways to enter lunar orbit: direct transfer, phasing loop transfer, weak stability boundary …

Tungsten dust used as an artificial atmosphere to aid in deorbiting of space debris should be
deployed soon after a fragmentation to be effective, before the delta-v imparted to each …

In this research, a new methodology named as LPG-Algorithm is designed to determine the
transfer trajectory between two celestial bodies or any two locales in space. It is constructed …

Abstract Near Earth objects (NEOs) are comets and asteroids that orbit the vicinity of the
Earth. The scientific interest in comets and asteroids is due in large part to their status as …

The present paper has the goal of studying orbital maneuvers of Rendezvous, that is an
orbital transfer where a spacecraft has to change its orbit to meet with another spacecraft …

A spacecraft placed in an Earth-Moon L2 quasi-halo orbit can maintain constant
communication between the Earth and the far side of the Moon. This quasi-halo orbit could …

O problema proposto por Johann Heinrich Lambert, resolvido por Joseph-Louis Lagrange, é
de extrema importância para o estudo de manobras orbitais, mesmo sendo proposto no …

Neste trabalho foi estudado a otimização do custo de missões interplanetárias dando
ênfase na redução do consumo de combustível. Com essa finalidade foi implementado um …
