Journal ArticleDOI
A model of global convection in Jupiter's magnetosphere
TL;DR: In this paper, a new global convection model for the Jovian magnetosphere is proposed, based on models of quasi-stationary plasma convection in the earth's magnetosphere.
Book ChapterDOI
The Near-Earth Asteroid Rendezvous Laser Altimeter
TL;DR: The Near Earth Asteroid Rendezvous (NEAR) spacecraft will enter a low-altitude orbit around the asteroid, 433 Eros, in 1999 after a 3-year transit as discussed by the authors.
Journal ArticleDOI
Leakage of energetic particles from Jupiter's dusk magnetosphere: dual spacecraft observations
Norbert Krupp,Joachim Woch,Andreas Lagg,S. A. Espinosa,Stefano Livi,Stamatios M. Krimigis,D. G. Mitchell,D. J. Williams,Andrew F. Cheng,Barry Mauk,R. W. McEntire,Thomas P. Armstrong,D. C. Hamilton,George Gloeckler,J. Dandouras,Louis J. Lanzerotti +15 more
TL;DR: Ferreira et al. as discussed by the authors showed that magnetospheric particles leak directly into the interplanetary medium from the closed magnetosphere, and are the source for the upstream particle events.
Journal ArticleDOI
The NEO (175706) 1996 FG3 in the 2–4 μm spectral region: Evidence for an aqueously altered surface
Andrew S. Rivkin,Ellen S. Howell,Ronald J. Vervack,C. Magri,Michael C. Nolan,Yan Fernandez,Andrew F. Cheng,M. Antonietta Barucci,Patrick Michel +8 more
TL;DR: In this paper, the spectral properties of the binary near-Earth Asteroid (175706) 1996 FG3 were analyzed using the NASA Infrared Telescope Facility (IRTF) spectrograms.
Journal ArticleDOI
A Model of Satellite Microsignatures for Saturn
Chris Paranicas,Andrew F. Cheng +1 more
TL;DR: In this paper, the authors model the time and longitude-dependent charged particle absorption signatures caused by solid body absorbers, such as icy satellites, in Saturn's magnetosphere, and calculate the reduction in particle density caused by passage of such an absorber through a magnetic flux tube.
