Numerical Solution of Wave Equations for the Stability of Inner Cometo-Sheath

Srivastava, K.; Tsurutani, B.; Goldstein, B. (1993)

Numerical solution of the MHD wave equations for stability of the cometary sheath determined by the balance between the inward Lorentz body force and the outward ion-neutral drag force is obtained by using a two-point ...
Numerical Studies of Hall Thruster Acceleration Region Electron Transport

Katz, Ira; Chaplin, Vernon H. Jr.; Ortega, Alejandro Lopez (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2018, 2018-07-09)

Azimuthal direction 1-D and azimuthal and axial direction 2-D Particle in Cell (PIC) simulations of the Hall thruster acceleration and near-plume regions are presented. The axial extent of the 2-D computational domain is ...

Numerical study of lander engine plume impingement on the surface off Europa

Lam, Rebekah; Maghsoudi, Elham; Hoey, William (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2019, 2019-06-03)

Plume exhaust from lander engines would be of concern when landing on the surface of Europa since it could have detrimental effects on both the landing surface and powered descent vehicle. The plume could also entrain ...
Numerically efficient direct solver-based full-wave model for EM scattering from complex-geometry particles

Fenni, Ines; Haddad, Ziad S.; Roussel, Helene; Mittra, Raj (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2018, 2018-03-04)
Numerically Integrated Orbits of the Major Saturnian Satellites fit to Earthbased Observations

Jacobson, R. A.; Vaughan, R. M. (1993-05)

We have fit numerically integrated orbits of the eight major satellites of Saturn to all available astrometric and meridian circle observations for the period of 1971 to 1992. The integration was carried out in cartesian ...
Numerically Optimized Coronagraph Designs for the Habitable Exoplanet Imaging Mission (HabEx) Concept

Riggs, A.J. Eldorado; Ruane, Garreth; Fogarty, Kevin; Pueyo, Laurent; Balasubramaian, Kunjithapatham (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2018, 2018-06-12)

The primary science goal of the Habitable Exoplanet Imaging Mission (HabEx), one of four candidate ﬂagship missions under investigation, is to image and spectrally characterize Earth-like exoplanets. It is well known that ...
The NUONCE Engine for LEO Networks

Lo, Martin (1995-03)

Typical LEO networks use constellations which provide a uniform coverage. However, the
