The Outer Planets

2014
Among the first facts that most people learn about the solar system is that its planets fall into two distinct categories. The innermost four—Mercury, Venus, Earth and Mars—are the terrestrial planets, with solid rocky surfaces. The outermost four—Jupiter, Saturn, Uranus and Neptune—are the gas giants—objects which are physically much larger and the ...

Outer planets proximity link protocol

2017 IEEE Aerospace Conference, 2017
A directional X-band proximity link protocol derived from the Consultative Committee for Space Data Systems (CCSDS) Proximity-1 protocol that accommodates link dynamics and end-to-end file transfer considerations is presented. This implementation is targeted for the NASA Europa Multiple Flyby (aka Clipper) and Lander Missions currently under study, and

THE ATMOSPHERES OF THE OUTER PLANETS

Annual Review of Earth and Planetary Sciences, 1976
Abstract Beyond the asteroid belt lie the giant planets, Jupiter, Saturn, Uranus and Neptune and their extensive satellite systems, and Pluto, which is more like a satellite than any of its giant companions. These large planets are huge, rapidly rotating bodies and seem to form two separate families.

The Outer Planet Mariner Spacecraft

Conference on the Exploration of the Outer Planets, 1975
The Mariner Jupiter/Saturn 1977 Spacecraft is designed to conduct a broad range of intensive investigations of the Jupiter and Saturn planetary systems, and of the interplanetary medium from earth to beyond Saturn. The spacecraft design has evolved from earlier Mariners, the Viking Orbiter, and the technology available for implementing long-life ...

Wave observations in outer planet magnetospheres

Space Science Reviews, 1985
The first measurements of plasma waves and wave-particle interactions in the magnetospheres of the outer planets were provided by instruments on Voyager 1 and 2. At Jupiter, the observations yielded new information on upstream electrons and ions, bow shock dissipation processes, trapped radio waves in the magnetospheres and extended Jovian magnetotail,

Formation of the outer planets

Space Science Reviews, 1973
A discussion is given of a number of physical processes which were probably important during the formation of the outer planets if these formed from a gaseous solar nebula in which magnetic effects were not important. Arguments are given that large-scale gravitational instabilities in the solar nebula did not occur.

Formation of the Outer Planets

Space Science Reviews, 2005
Models of the origins of gas giant planets and ‘ice’ giant planets are discussed and related to formation theories of both smaller objects (terrestrial planets) and larger bodies (stars). The most detailed models of planetary formation are based upon observations of our own Solar System, of young stars and their environments, and of extrasolar planets.

Outer planet entry nonequilibrium heating

Conference on the Exploration of the Outer Planets, 1975
An analytical tool has been developed which enables the impact of nonequilibrium effects on outer planet entry heating to be estimated. The analysis combines recent shock tube experiments, flow field calculations, and planetary entry trajectory analysis.
