Quasi Satellite Orbits to observe a possible small moon of Pallas
(2020-02-01)
The purpose of this paper is to make a numerical search for natural orbits that can be used for a spacecraft to study a possible small moon of Pallas. There are many speculations about the existence of a small companion ...
Orbit maintenance of quasi-satellite trajectories via mean relative orbit elements
(2018-01-01)
The Martian Moons eXploration mission is currently under development at JAXA and will be the first spacecraft mission to retrieve pristine samples from the surface of Phobos. In preparation for the sampling operations, MMX ...
Time analysis for temporary gravitational capture - Stable orbits
(Edp Sciences S A, 2001-10-01)
In a previous work, Vieira Neto & Winter (2001) numerically explored the capture times of particles as temporary satellites of Uranus. The study was made in the framework of the spatial, circular, restricted three-body ...

On the effects of each term of the geopotential perturbation along the time I: Quasi-circular orbits
(Elsevier B.V., 2014-09-15)
This paper provides a useful new method to determine minimum and maximum range of values for the degree and order of the geopotential coefficients required for simulations of orbits of satellites around the Earth. The ...
SEARCHING FOR MID-RANGE PLANAR ORBITS TO OBSERVE DEIMOS
(Univ Nacional Autonoma Mexico, Inst De Astronomia, 2019-10-01)
In this paper we search for mid-range planar orbits for a spacecraft traveling in the neighborhood of Deimos. The first task is to perform a numerical search to find and classify mid-range natural orbits around Deimos that ...
Numerical study of low-cost alternative orbits around the Moon
(Elsevier B.V., 2005-01-01)
In this paper, we have investigated a region of direct stable orbits around the Moon, whose stability is related to the H2 Family of periodic orbits and to the quasi-periodic orbits that oscillate around them. The stability ...
