On the mechanisms of natural transport in the solar system
Masdemont Soler, Josep; Ren, Yuan; Gómez Muntané, Gerard; Fantino, Elena (2010)
Text en actes de congrés
Accés obertSome minor bodies in the solar system (i.e., comets, asteroids and planetary ejecta) are capable of performing transfers from their original location to very distant places, provided they possess sufficiently large ... -
On the relationship between the weak stability boundary region of the earth and the low-energy transfers to the moon
Masdemont Soler, Josep; Ren, Yuan; Gómez Muntané, Gerard; Fantino, Elena (2009)
Text en actes de congrés
Accés obertThe term Weak Stability Boundary (WSB) is related to a region of stable motion around the second primary of a circular restricted three-body problem (CR3BP). Previous work on this subject has shown that, at a given energy ... -

On the solution of Lambert's problem by regularization
Torre Sangrà, David de la; Flores Le Roux, Roberto Maurice; Fantino, Elena (2018-12)
Article
Accés obertLambert's problem is the two-point boundary-value problem resulting from a two-body orbital transfer between two position vectors in a given time. It lies at the very heart of several fundamental astrodynamics and space ... -
Optimal low-thrust transfers between libration point orbits
Ren, Yuan; Pergola, Pierpaolo; Fantino, Elena; Thiere, B. (2012-01)
Article
Accés restringit per política de l'editorialOver the past three decades, ballistic and impulsive trajectories between libration point orbits (LPOs) in the Sun–Earth–Moon system have been investigated to a large extent. It is known that coupling invariant manifolds ... -
Reduction of Saturn orbit insertion impulse using deep-space low thrust
Fantino, Elena; Flores Le Roux, Roberto Maurice; Peláez Álvarez, Jesús; Raposo-Pulido, Virginia (American Institute of Aeronautics and Astronautics, 2020-02-17)
Article
Accés obertOrbit insertion at Saturn requires a large impulsive manoeuver due to the velocity difference between the spacecraft and the planet. This paper presents a strategy to reduce dramatically the hyperbolic excess speed at ... -
Review of Lambert's problem
Torre Sangrà, David de la; Fantino, Elena (2015)
Comunicació de congrés
Accés obertLambert’s problem is the orbital boundary-value problem constrained by two points and elapsed time. It is one of the most extensively studied problems in celestial mechanics and astrodynamics, and, as such, it has always ... -
Star visibility and tracking from the Space Station
Bernacca, Pier Luigi; Facchinetti, Claudia; Fantino, Elena (2010-12)
Article
Accés restringit per política de l'editorialPurpose of the present study is to provide algorithms for and examples of how to simulate star visibility and tracking by a Telescope attached to the main truss of the International Space Station (ISS). The sky visibility ... -
Two mechanisms of natural transport in the Solar System
Ren, Yuan; Gomez Muntaner, Gerard; Masdemont Soler, Josep; Fantino, Elena (2011)
Article
Accés restringit per política de l'editorialIn this paper, two natural transport mechanisms in Solar System are considered. The first is a short-time transport, and is based on the existence of ‘‘pseudo-heteroclinic’’ connections between libration point orbits of ...
