  • Quadrelli, Marco B. (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2013, 2013-09-10)
    In this paper, we present some ideas regarding the modeling, dynamics and control aspects of granular spacecraft. Granular spacecraft are complex multibody systems composed of a spatially disordered distribution of a large ...
  • Quadrelli, Marco B.; Chang, Johnny; Kowalchuck, Scott (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2004., 2004-02)
    This paper describes the model and the algorithm developed for an aerobot blimb guiding and controlling a herd of sondes on the surface of Titan. The paper summarizes the derivation of the equations of motion used in ...

    In this paper we present some ideas regarding the modeling, dynamics and control aspects of granular spacecraft. Granular spacecraft are complex multibody systems composed of a spatially disordered distribution of a large ...
  • Quadrelli, Marco B.; Arumugam, Darmindra (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2018, 2018-03-03)
    Granular media in space can be used in the radar and microwave bands to enable imaging of previously inaccessible regions of targets with high geophysical variations with time, such as comets. The means of imaging, ...
  • Quadrelli, Marco B. (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2004., 2004-04-16)
    The dynamics and control challenges presented by the Jovian Moon Tour spacecraft are described in this paper.
  • Quadrelli, Marco B.; Mettler, Edward; Langmaier, Jerry K. (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2004., 2004-08-15)
    The dynamics and control challenges presented by a conceptual Jovian Moon Tour spacecraft are summarized in this paper. Attitude and orbital dynamics interactions are present due to the designed low-thrust trajectory, and ...
  • Bellan, J. (1994-12-05)
    Collective drop behavior is encountered in sprays produced for a variety of applications. The existence of clusters of drops indicates that the interaction among the drops is important in determining the dynamics of the ...

  • Sekanina, Z. (1995)
    This paper summarizes recent progress in our understanding of the morphological diversity of dust comets. This diversity is a product of dust emission from discrete active areas on the nucleus surface and provides information ...
  • Sekanina, Z. (1995-08)
    The paper reviews recent progress in understanding of the diversity of cometary dust features (such as jets, fans, halos, and envelopes), which are products of particle ejections from discrete emission regions on the nucleus ...
  • Maccarini, P. F.; Pogorzelski, R. J. (1998-06-21)
    Arrays of coupled oscillators have been proposed as means of realizing high power rf sources via coherent spatial power combining.
  • Ploen, Scott R.; Hadaegh, Fred.Y.; Acikmese, A. Behcet; Scharf, Daniel P. (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2004., 2004-11-08)
    In this paper the translational equations of motion of a formation of n spacecraft in Earth orbit, nf of which are drag-free spacecraft, are derived in a coordinate-free manner using the balance of linear momentum and ...
  • Ploen, Scott R.; Scharf, Daniel P.; Hadaegh, Fred Y.; Acikmese, Ahmed B. (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2004, 2004-08-16)
    In this paper the equations of motion of a formation consisting of n spacecraft in Earth orbit are derived via Lagrange’s equations. The equations of motion of the formation are developed with respect to both (1) a bound ...
  • Roman, A. (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2019, 2019-11-04)
  • Zak, M. (2000)
    Recent advances in nonlinear dynamics demonstrate a remarkable complexity of patterns outside of equilibrium, which are derived from simple basic laws of physics.
  • Wada, B. (1993)
    This paper presents an overview of the challenges encountered in the prediction and ground test verification of structural dynamics for on-orbit control of large precision space structures.
