Building an 'Escape Portal' with Tethers Fixed in Asteroids

Autor: T. G. G. Chanut, Antonio F. B. A. Prado, Vivian Martins Gomes

Publikováno v: The Journal of the Astronautical Sciences. 65:355-375

The main idea of this paper is to propose the construction of an “Escape Portal” to send a spacecraft to the exterior planets, or even to make it escape from the Solar System, using a Tethered Sling Shot Maneuver (TSSM) with an asteroid. The cons

The Gefion asteroid family is a group of S-type asteroids located between the 8J:-3A and 5J:-2A mean-motion resonances. The 5J:-2A resonance seems to be responsible for the absence of the right side of the V-shape of this family. We aim in this work

Dynamics in the vicinity of (101955) Bennu: solar radiation pressure effects in equatorial orbits

Autor: Safwan Aljbaae, Valerio Carruba, Antonio F. B. A. Prado, T. G. G. Chanut

Here we study the dynamical effects of the solar radiation pressure (SRP) on a spacecraft that will survey the near-Earth rotating asteroid (101955) Bennu when the projected shadow is accounted for. The spacecraft's motion near (101955) Bennu is mode

One of the most accurate models currently used to represent the gravity field of irregular bodies is the polyhedral approach. In this model, the mass of the body is assumed to be homogeneous, which may not be true for a real object. The main goal of
