Book excerpt: Analysis of nonthermal radio emission data obtained by the Planetary Radio Astronomy (PRA) spectrometers on the Voyager 1 and 2 spacecraft was performed. This PRA data provided unique insights into the radio emission characteristics of the outer planets because of PRA's unique spectral response below the terrestrial ionospheric plasma frequency and its unprecedented proximity to the source. Of those results which were documented or published, this final report surveys only the highlights and cites references for more complete discussions. Unpublished results for Uranus, Neptune, and theoretical Ionian current distributions are presented at greater length. The most important conclusion to be drawn from these observations is that banded spectral emission is common to the radio emission below 1-2 MHz observed from all four Jovian planets. In every case multiple spectral features evolve on time scales of seconds to minutes. To the extent these features drift in frequency, they appear never to cross one another. The Neptunian spectral features appear to drift little or not at all, their evolution consisting principally of waxing and waning. Since other evidence strongly suggests that most or all of this radio emission is occurring near the local magnetospheric electron cyclotron frequency, this implies that this emission preferentially occurs at certain continually changing planetary radii. It remains unknown why certain radii might be favored, unless radial electric field components or other means serve to differentiate radially the magnetospheric plasma density, particle energy vectors, or particle coherence. Calculation of the spatial distribution and intensity of the Io-generated magnetospheric currents are also presented; these currents may be limited principally by wave impedance and local field strengths.

Download or read book NASA s Voyager Missions written by Ben Evans and published by Springer Nature. This book was released on 2022-08-23 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2022 marks the 45th anniversary of the Voyager probe launches. Launched into space in 1977, these twin probes explored the farthest reaches of the Solar System before venturing on a one-way journey beyond, all the while testing the bounds of science, robotic exploration and our collective imagination. This heavily revised commemorative book takes a comprehensive look at their incredible achievements, future potential and overall legacy. Chronicled herein is an epic journey to unveil the mysterious outer reaches of the Solar System for the first time. The book recounts the Voyagers’ travels through the asteroid belt and past the giant gaseous planets Jupiter and Saturn, as well as Voyager 2’s forays near the distant ice giants Uranus and Neptune. Each chapter details in full the game-changing scientific data and glorious imagery they sent back to Earth. This new edition incorporates all the new data we have learned in the nearly 20 years since its original publication, discussing how the knowledge first gleaned with Voyager has been built upon in subsequent decades by Cassini, Juno and New Horizons. The Voyager probes captured imaginations around the world; now is an opportune time to reflect on their unparalleled quest across the edges of the Solar System and the enigmatic interstellar medium beyond.

Book excerpt: “Fascinating . . . memorable . . . revealing . . . perhaps the best of Carl Sagan’s books.”—The Washington Post Book World (front page review) In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time. Future generations will look back on our epoch as the time when the human race finally broke into a radically new frontier—space. In Pale Blue Dot, Sagan traces the spellbinding history of our launch into the cosmos and assesses the future that looms before us as we move out into our own solar system and on to distant galaxies beyond. The exploration and eventual settlement of other worlds is neither a fantasy nor luxury, insists Sagan, but rather a necessary condition for the survival of the human race. “Takes readers far beyond Cosmos . . . Sagan sees humanity’s future in the stars.”—Chicago Tribune
