Removing energy from a spacecraft using tethers
(2019-01-01)
For a mission whose focus is the capture of the spacecraft by the main body or a close approach for observation, removing energy from a spacecraft can be an important maneuver. An option is the Tethered Slingshot Maneuver ...
An interplanetary mission to Neptune system: Gravitational capture and maneuvers around triton
(2007-12-01)
The gravitational capture was initially used to understand the capture of planetary satellites. However, in the 90's decade, this phenomenon was applied in spacecraft trajectories. Belbruno and Miller studied missions in ...
Tethered slingshot maneuver in the three-dimensional space
(2018-01-01)
The Tethered Slingshot maneuver (TSSM) is an alternative solution to maneuver a spacecraft in space, which is based in the use of cables. A space tether usually consists in two fixed objects at the end of a cable. In this ...
TRAJECTORY ANALYSIS OF A SPACECRAFT MAKING A THREE-DIMENSIONAL POWERED SWING-BY MANEUVER
(Univelt Inc, 2019-01-01)
The present paper studies the problem of orbital maneuvers performed combining the passage of a spacecraft by a celestial body with an impulse applied to the spacecraft during the close approach. The motion of the spacecraft ...
Trajectory analysis of a spacecraft making a three-dimensional powered swing-by maneuver
(2018-01-01)
The present paper studies the problem of orbital maneuvers performed combining the passage of a spacecraft by a celestial body with an impulse applied to the spacecraft during the close approach. The motion of the spacecraft ...
Aero-gravity powered maneuvers to change the inclination of a spacecraft
(2015-01-01)
This paper study orbital maneuvers to change the inclination and the energy of a spacecraft using close approaches between a spacecraft and a planet. It is considered the presence of an atmosphere in the planet and the ...
Effects of the eccentricity on the primames in the gravitational capture phenomenon
(2006-05-23)
Gravitational capture is a characteristic of some dynamical systems in celestial mechanics, as in the elliptic restricted three-body problem that is considered in this paper. The basic idea is that a spacecraft (or any ...
Optimal impulsive control in a powered Swing-By
(2013-09-16)
This paper studies the problem of applying an impulsive control in a spacecraft that is performing a Swing-By maneuver. The objective is to study the changes in velocity, energy and angular momentum for this maneuver as a ...
The aster mission: Exploring for the first time a triple system asteroid
(2011-12-01)
2001 SN263 is a triple system asteroid. Although it was discovery in 2001, in 2008 astronomical observation carried out by Arecibo observatory revealed that it is actually a system with three bodies orbiting each other. ...
Orbital maneuvers to form a constellation of small satellites from a single large spacecraft
(2019-11-04)
The main goal of the present paper is to show how to form a constellation of small satellites when all small satellites leave from a larger spacecraft. It is assumed that they will all stay in a planar formation, in the ...
