      Pioneer venus results: an overview. Donahue TM. A summary is presented of the scientific results obtained during the first days of the Pioneer Venus orbiter mission and produced by analysis of multiprobe data as of about 1 April The summary is essentially a guide to the material presented in the reports devoted to Pioneer Venus Cited by: The Pioneer Venus Orbiter was designed to operate for 8 months or more making direct and remote sensing measurements. The Pioneer Venus Multiprobe spacecraft was designed to separate into 5 separate atmospheric entry craft some million km (8 million miles) before reaching Venus.

The StarChild site is a service of the High Energy Astrophysics Science Archive Research Center (HEASARC), Dr. Alan Smale (Director), within the Astrophysics Science Division (ASD) at NASA/ GSFC. Venus - Venus - Spacecraft exploration: The greatest advances in the study of Venus were achieved through the use of robotic spacecraft. The first spacecraft to reach the vicinity of another planet and return data was the U.S. Mariner 2 in its flyby of Venus in Since then, Venus has been the target of more than 20 spacecraft missions.

Pioneer Venus consisted of two spacecraft: the Orbiter and the Multiprobe. The Orbiter carried an assortment of instruments for investigating plasma in upper Venusian atmosphere, observing reflected sunlight from the cloud layers at a variety of wavelengths, in addition to a surface radar mapper, and was launched on the The Pioneer Venus Multiprobe was launched on 8 August It encountered Venus on 9 December It consisted of 5 separate probes: the probe transporter (referred to as the Bus), a large atmospheric entry probe (called Sounder), and 3 identical small probes (called North, Day, and Night).

InNASA published The Pioneer Venus Orbiter: 11 Years of Data, A Laboratory for Atmospheres Seminar Talk, by W. Kasprzak. The report details many of the scientific results of Pioneer Venus. The report details many of the scientific results of Pioneer Venus.

An IR remote sensing instrument, similar in principle to some of those on terrestrial meteorological satellites, was flown to Venus on board the Pioneer Venus orbiter. Observations of the atmosphere were made from 5 December until 14 Februaryduring seventy-two orbits of the planet. The optical techniques employed and the design and implementation of the instrument are described.

Pioneer Venus 2, the sistership to Pioneer Venus 1, consisted of the main spacecraft, a large probe, and three identical small probes—all designed to collect data as they descended toward the surface of Venus. Amazingly two probes survived the hard impact and one transmitted data from the.

The Gamma Burst Detector aboard the Pioneer Venus Orbiter was designed to record gamma ray burst intensity profiles with high time resolution.

The Detector consists of two identical sensors placed at the periphery of the spacecraft equipment platform. They are. The dark horizontal Y feature recurs quasi-periodically, at intervals of about 4-days, but it has also been absent for periods of several weeks. Bow-shaped features observed in Pioneer Venus images are farther upstream from the subsolar point than those in Mariner 10 images.

Get PDF ( kB. Document is scanned, no OCR.). The first spacecraft of this series to be launched was the Pioneer Venus Orbiter on during the first day of its three-week launch window. Called Pioneer Venus 1 (and sometimes Pioneer 12) after being successfully sent on its way by Atlas-Cent the Orbiter followed a long Type II trajectory that took it out to an aphelion of AU outside of Earth’s orbit before it started.

Pioneer Venus Orbiter will make the longest observations yet of Venus. It will be the first U.S. spacecraft to orbit the planet. To reach Venus, the Orbiter will fly more than half way around the Sun on its seven-month journey, some million km ( million mi.), traveling outside the Earth's orbit for.

In International Geophysics, Geophysical Data on Venus. The density of Venus has been determined from the gravitational mass, measured by tracking Venus-orbiting spacecraft such as the Pioneer Venus Orbiter and the Magellan Venus radar mapper, and the radius, determined directly from Earth-based radar studies of the planet.

The mass is found to be × 10 27 g. The Pioneer Venus Orbiter was inserted into an elliptical orbit around Venus on December 4, The Orbiter was a flat cylinder m in diameter and m high.

All instruments and spacecraft subsystems were mounted on the forward end of the cylinder, except the. 40 Years Ago, Pioneer Venus Orbiter Launched on Quest to Study Atmosphere of Earth’s Closest Neighbor. After the success of Pioneers 10 NASA’s Ames Research Center in California’s Author: Danielle Carmichael.

PREFACE The Hughes Aircraft Company Pioneer Venus final report is based on study task reports prepared during performance of the "System Design Study of the Pioneer Spacecraft.".

These task reports were forwarded to Ames Research Center as they were completed during the File Size: 6MB. The Pioneer Venus Orbiter, also known as Pioneer Venus 1 or Pion was a mission to Venus conducted by the United States as part of the Pioneer Venus project.

Launched in May atop an Atlas-Centaur rocket, the spacecraft was inserted into an elliptical orbit around Venus on December 4. The Orbiter Cloud Photopolarimeter (OCPP) onboard the Pioneer Venus Orbiter spacecraft serves both as a spin-scan imaging system providing km resolution images of the ultraviolet ( nm) cloud features and as a polarimeter yielding low resolution maps in Cited by: Pioneer 12 Pioneer Venus Orbiter Part of the Pioneer program Pioneer Venus Orbiter was designed to perform long-term observations of the Venusian atmosphere and surface features.

After entering orbit around Venus inthe spacecraft returned global maps of the planet's clouds, atmosphere and ionosphere, measurements of the atmosphere-solar. Pioneer Program Overview. The Pioneer program was a series of exploration probes launched between and Pioneer probes conducted various missions, including some of the first lunar probes, investigations of conditions in interplanetary space, exploration of the planet Venus, as well as the first flybys of Jupiter and Saturn.

The Pioneer Venus Orbiter has been in operation since orbit insertion on December 4, For the past 11 years, it has been acquiring data in the salient features of the planet, its atmosphere, ionosphere, and interaction with the solar wind.

The Pioneer Venus Orbiter was the first of a two-spacecraft orbiter-probe combination designed to conduct a comprehensive investigation of the atmosphere of Venus.

The spacecraft was a solar-powered cylinder about cm in diameter with its spin axis spin-stabilized perpendicular to the ecliptic plane. Abstract: The Pioneer Venus Orbiter Neutral Mass Spectrometer (ONMS) is designed to measure the vertical and horizontal density variations of the major neutral constituents in the upper atmosphere of Venus.

The mass spectrometer sensor includes a retarding potential ion source, hyperbolic quadrupole rod analyzer, and electron multiplier detector.
