Magnetic field studies by voyager 2: preliminary results at saturn.
Further studies of the Saturnian magnetosphere and planetary magnetic field by Voyager 2 have substantiated the earlier results derived from Voyager 1 observations in 1980. The magnetic field is primarily that of a centered dipole (moment = 0.21 gauss-RS(3); where one Saturn radius, RS, is 60,330 kilometers) tilted approximately 0.8 degrees from the rotation axis. Near closest approach to Satur...
متن کاملPlanetary radio astronomy observations from voyager 2 near saturn.
Planetary radio astronomy measurements obtained by Voyager 2 near Saturn have added further evidence that Saturnian kilometric radiation is emitted by a strong dayside source at auroral latitudes in the northern hemisphere and by a weaker source at complementary latitudes in the southern hemisphere. These emissions are variable because of Saturn's rotation and, on longer time scales, probably b...
متن کاملPlasma waves near saturn: initial results from voyager 1.
The Voyager 1 plasma wave instrument detected many familiar types of plasma waves during the encounter with Saturn, including ion-acoustic waves and electron plasma oscillations upstream of the bow shock, an intense burst of electrostatic noise at the shock, and chorus, hiss, electrostatic electron cyclotron waves, and upper hybrid resonance emissions in the inner magnetosphere. A clocklike Sat...
متن کاملTilting Saturn. I. Analytic Model
The tilt of Saturn’s spin axis to its orbit plane is 26N7, while that of Jupiter is only 3N1. We offer an explanation for this puzzling difference owing to gravitational perturbations of Saturn by the planet Neptune. A similarity between the precession period of Saturn’s spin axis and the 1:87 ; 10 yr precession period of Neptune’s slightly inclined orbit plane implicates a resonant interaction...
متن کاملVoyager 1 at Saturn An Encounter with a Multi - ringed Giant
1e Voyager project, a national enterprise involving several thousand individuals who built the spacecraft, several hundred at Caltech's Jet Propulsion Laboratory who fly it, and approximately a hundred scientists who are analyzing the data, began, in a sense, with one man and his telescope. In 1610 Galileo turned that telescope toward Saturn and observed some odd appendages, somewhat like cup h...
