Further advances on low-energy lunar impact dynamics
Alessi, Elisa Maria; Gómez, Gerard; Masdemont Soler, Josep (2010-02)
Article
Accés restringit per política de l'editorialWe extend the analysis, started in a previous work [1], concerning the formation of lunar impact craters due to low-energy trajectories. First, we adopt the Circular Restricted Three- Body Problem and consider different ... -
Leaving the Moon by means of invariant manifolds of libration point orbits
Masdemont Soler, Josep; Alessi, Elisa Maria; Gómez, Gerard (Elsevier, 2009)
Article
Accés restringit per política de l'editorialThe aim of this work is to look for rescue trajectories that leave the surface of the Moon, belonging to the hyperbolic manifolds associated with the central manifold of the Lagrangian points L1 and L2 of the Earth–Moon ... -
Low-energy impact dynamics in the Earth – Moon system
Masdemont Soler, Josep; Gómez Muntané, Gerard; Alessi, Elisa Maria (2010)
Text en actes de congrés
Accés obertMost of the craters on the surface of the Moon were created by the collision of minor bodies of the Solar System, in particular asteroids coming from the Main Belt as a consequence of different types of resonance. Our ... -
Transfer orbits in the Earth-Moon system and tefinement to JPL ephemerides
Masdemont Soler, Josep; Gómez Muntané, Gerard; Alessi, Elisa Maria (2009)
Text en actes de congrés
Accés obertWe describe how to determine transfers between libration point orbits and either the surface of the Moon or a Low Earth Orbit within the Circular Restricted Three – Body Problem (CR3BP) assumptions. Moreover, we explain ... -
Two-manoeuvers transfers between LEOs and Lissajous orbits in the Earth-Moon system
Masdemont Soler, Josep; Gómez, Gerard; Alessi, Elisa Maria (2010)
Article
Accés restringit per política de l'editorialThe purpose of this work is to compute transfer trajectories from a given Low Earth Orbit (LEO) to a nominal Lissajous quasi-periodic orbit either around the point L1 or the point L2 in the Earth–Moon system. This is ...
