An overview of the Voyager 2 encounter with Neptune is presented, including a brief discussion of the trajectory, the planned observations, and highlights of the results described in the 11 companion papers. Neptune's blue atmosphere has storm systems reminiscent of those in Jupiter's atmosphere. An optically thin methane ice cloud exists near the 1.5-bar pressure level, and an optically thick cloud exists below 3 bars. Neptune's magnetic field is highly tilted and offset from the planet's… 

Geophysics news 1990: Voyager 2 at Neptune and Triton

Voyager 2 completed its “grand tour” of the outer solar system in 1989 by returning the first in situ observations of Neptune, its rings, and its satellites. The probe revealed that the Neptunian

The Encounter of Voyager 2 with Neptune’s Magnetosphere

The particles and fields complement of instruments on the Voyager 2 spacecraft performed a comprehensive set of measurements during the encounter with the Neptune system on August 24 through 28,

Design of a low cost mission to the Neptunian system

Visited only by Voyager 2 in 1989, Neptune and its moon Triton hold important clues to the formation and evolution of the solar system and exoplanetary systems. Neptune-sized planets are the most

The Voyager encounter with Neptune

The Voyager Neptune/Interstellar Mission is the continuation of the NASA program of exploration of the outer solar system. The prior phases of the Voyager program included encounters with Jupiter,

The atmosphere of Neptune: Results of radio occultation measurements with the Voyager 2 spacecraft

Radio tracking data acquired during Voyager 2's occultation by Neptune have been used to study the thermal structure and composition of Neptune's troposphere and stratosphere. The occultation began

Abstract The encounter of the spacecraft Voyager 2 with Neptune and its large satellite Triton in August 1989 will provide a crucial test of ideas regarding the origin and chemical composition of the

A model of dust production in the Neptune ring system

Voyager 2 images of the Neptunian ring system show it to be relatively dusty with the fraction of micron-sized dust particles in the rings between about 0.2 and 0.7 (Smith et al 1989). We apply a

Neptune and Triton: Essential pieces of the Solar System puzzle

Triton, Pluto, Centaurs, and Trans-Neptunian Bodies

The diverse populations of icy bodies of the outer Solar System (OSS) give critical information on the composition and structure of the solar nebula and the early phases of planet formation. The two

Winds of Neptune - Voyager observations of cloud motions

High temporal and spatial resolution images acquired from Voyager cameras have been used to measure cloud motions to improve the meridional profile of the zonal mean circulation on Neptune. A wide

Neptune's Wind Speeds Obtained by Tracking Clouds in Voyager Images

Images of Neptune obtained by the narrow-angle camera of the Voyager 2 spacecraft reveal large-scale cloud features that persist for several months or longer, and wind speeds computed with respect to this radio period are roughly the same for all the planets ranging from Venus to Neptune.

Occultation by a Possible Third Satellite of Neptune

The 24 May 1981 close approach of Neptune to an uncataloged star was photoelectrically monitored from two observatories separated by 6 kilometers parallel to the occultation track, and an 8.1-second drop in signal is interpreted as resulting from the passage of a third satellite of Neptune in front of the star.

Neptune's Story

It is conjectured that Triton was captured from a heliocentric orbit as the result of a collision with what was then one of Neptune's regular satellites, thus accounting for that satellite's highly eccentric and inclined orbit.

Lyttleton hypothesized long ago that Triton and Pluto originated as adjacent prograde satellites of Neptune1. With the presently accepted masses of Triton and Pluto–Charon2,3, however, the momentum
