This report is an introduction to the accompanying collection of early results from the Pioneer Venus orbiter and multiprobe missions, which encountered Venus on 4 December and 9 December 1978, respectively. Initial results for the multiprobe mission and for the first 30 days of the orbiter mission were reported in the 23 February issue of Science. Additional mission features and updated mission parameters based on refined tracking data and trajectory computations are presented here. New…

Measurements of Turbulence in the Venus Atmosphere Deduced from Pioneer Venus Multiprobe Radio Scintillations
TLDR
The Pioneer Venus measurements provide a resolution of the long-standing order of magnitude discrepancy between these earlier measurements of cn and the deduced estimates of the upper bound of structure constant cn of the refractive index fluctuations.
Venus gravity: A high-resolution map
The Doppler data from the radio tracking of the Pioneer Venus Orbiter (PV0) have been used in a two-stage analysis to develop a high-resolution map of the gravitational potential of Venus,
Vertical structure of the atmosphere of Venus from Pioneer Venus orbiter radio occultations
Between December 1978 and February 1979 the Pioneer Venus orbiter spacecraft returned some 140 S band and X band radio occultation measurements of the Venus atmosphere. Results from 13 measurements,
The clouds of Venus: A synthesis report
The results presented represent a synthesis of data from those Pioneer Venus experiments directed toward studying cloud problems. These orbiter and multiprobe experiments show the cloud system to
Observations of large scale steady magnetic fields in the nightside Venus ionosphere and near wake
Pioneer Orbiter Magnetometer observations during the few minutes surrounding nightside periapsis traversals generally show a weak average field of magnitude <10 gammas between approx.200 km and the
Morphology of the Venus Ultraviolet Night
Images of the nightside of Venus in the (0,1)/J band of nitric oxide have been obtained by the Pioneer Venus orbiter ultraviolet spectrometer (OUVS). The emission, which is produced by radiative
Morphology of the Venus ultraviolet night airglow
Images of the nightside of Venus in the (0,1)delta band of nitric oxide have been obtained by the Pioneer Venus orbiter ultraviolet spectrometer (OUVS). The emission, which is produced by radiative
Observations of large scale steady magnetic fields in the dayside Venus ionosphere
Although the dayside ionosphere of Venus is often “field-free” except for fine scale features, large scale, steady ionospheric magnetic fields with magnitudes sometimes exceeding 100 gammas are
Mass spectrometric measurements of the neutral gas composition of the thermosphere and exosphere of Venus
The neutral gas composition and density in the thermosphere of Venus is being measured with a quadrupole mass spectrometer on the Pioneer Venus orbiter. Data are obtained near periapsis once per day
Chemical and Isotopic Composition Measurements on Atmospheric Probes Exploring Uranus and Neptune
So far no designated mission to either of the two ice giants, Uranus and Neptune, exists. Almost all of our gathered information on these planets comes from remote sensing. In recent years, NASA and
