      In this paper we address the feasibility of capturing small Near-Earth Asteroids (NEAs) into the vicinity of the Sun-Earth L-2 libration point using a continuous-thrust propulsion system assumed to be attached to the ...
    • Capturing small asteroids into Sun-Earth Lagrangian points for mining purposes 

      Lladó, Neus; Ren, Yuan; Masdemont Soler, Josep; Gomez Muntaner, Gerard (2012)

      Accés obert
      The aim of this paper is to study the capture of small Near Earth Objects (NEOs) into the Sun-Earth L2 using low-thrust propulsion for mining or science purposes. As it is well known, the vicinity of these points is inside ...

      The purpose of this paper is to obtain a third-order expression, for the in-plane and out-of-plane amplitudes, of the solutions of the elliptic Hill–Clohessy–Wiltshire non-linear equations. The resulting third-order solution ...
    • 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 obert
      Some 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

      Accés obert
      The 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 ...

      Accés restringit per política de l'editorial
      Over 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 ...
    • Two mechanisms of natural transport in the Solar System

      Article
      Accés restringit per política de l'editorial
      In 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 ...
