    • On the solution of Lambert's problem by regularization 

      Torre Sangrà, David de la; Flores Le Roux, Roberto Maurice; Fantino, Elena (2018-12)
      Article
      Open Access
      Lambert'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 ...
    • Optimization of interplanetari trajectories with gravity assist 

      Torre Sangrà, David de la (Universitat Politècnica de Catalunya, 2020-07-28)
      Doctoral thesis
      Open Access
      Interplanetary travel is a difficult task due to the high fuel mass required to reach other planets. Minimizing the cost of the manoeuvres (and, in turn, the fuel mass) is the objective preliminary mission design. During ...
    • Review of Lambert's problem 

      Torre Sangrà, David de la; Fantino, Elena (2015)
      Conference lecture
      Open Access
      Lambert’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 ...
    • Study of the Martian environment for application to the design of a greenhouse 

      Torre Sangrà, David de la (Universitat Politècnica de Catalunya, 2014-07)
      Master thesis (pre-Bologna period)
      Open Access
      The human exploration of Mars belongs to the current plans of NASA and ESA. Getting the astronauts to Mars and returning them safely to Earth imposes several engineering challenges. In particular, creating the conditions ...
