Pioneer 4

title	Pioneer 4
date	03.03.1959
description	Pioneer 4 was a spin stabilized spacecraft launched on a lunar flyby trajectory and into a heliocentric orbit making it the first US probe to escape from the Earth's gravity. It carried a payload similar to Pioneer 3: a lunar radiation environment experiment using a Geiger-Mueller tube detector and a lunar photography experiment. It passed within 60,000 km of the Moon's surface. However, Pioneer 4 did not come close enough to trigger the photoelectric sensor. No lunar radiation was detected. The spacecraft was still in solar orbit as of 1969. Image Credit: NASA

View of Jupiter

Title	View of Jupiter
Full Description	This view of Jupiter shows the giant planet's cloud tops taken by the Pioneer 10 spacecraft as it flew past Jupiter last December. This view was taken from 2,695,000 kilometers (1,842,451 miles) away. It shows the 25,000 mile long Great Red Spot, which is large enough to swallow up several Earths. Individual cloud formations are visible in some detail. The bright zones appear to become split up into the detailed flow patterns of Jupiter's atmosphere and clouds. The area surrounding the Spot in the bright South Tropical Zone, suggests a flow pattern about the Spot which is bulged toward the north by the Spot. The Spot may be a gigantic "permanent hurricane." The gigantic cloud swirls are thousands or more miles across. Pioneer 10 flew past Jupiter in December 1974 and flew past the orbit of Pluto in 1987. A sister spacecraft, Pioneer 11 reached Jupiter in December 1975. The Pioneer Project was managed by NASA's Ames Research Center, Mountain View, Calafornia. The spacecraft was built by TRW Systems.

Pioneer 10 Trajectory

Title	Pioneer 10 Trajectory
Full Description	This image, drawn in 1970, is an artist's rendering of the Pioneer 10 spacecraft trajectory, with the planets labeled and a list of the instruments that were intended to be flown. Before the use of computer animation, artists were hired by JPL and NASA to depict a spacecraft in flight, for use as a visual aid to promote the project during development. Pioneer 10 was managed by NASA Ames Research Center in Moffett Field, California. The Pioneer F spacecraft, as it was known before launch, was designed and built by TRW Systems Group, Inc. JPL developed three instruments that flew on the spacecraft: Magnetic Fields, S-Band Occultation, and Celestial Mechanics, as well as running the Deep Space Network which provided tracking and data system support. Caltech was responsible for the Jovian Infrared Thermal Structure experiment. Pioneer was very successful, crossing the orbit of Mars and the asteroid belt beyond it, encountering, studying, and photographing Jupiter, then crossing the orbits of Saturn, Uranus, and Neptune. It left the solar system in 1983 and has been contacted several times in the past few years. As of July 2001, the spacecraft was still able to send a return signal to Earth. At Jupiter, the experiments of Pioneer were used to examine the environmental and atmospheric characteristics of the giant planet. Pioneer was also the vital precursor to all future flights to the outer solar system. It determined that a spacecraft could safely fly through the asteroid belt. It also measured the intensity of Jupiter's radiation belt so that NASA could design future Jupiter (and other outer planets) orbiters.

Composite Pioneer 10 imagery …

1973

Description	Composite Pioneer 10 imagery Excitement rose as the PICS displayed images of Jupiter of ever-increasing size as Pioneer 10 plunged at high speed toward its closest approach to the planet. The most dramatic moment was perhaps after closest approach and after the spacecraft has been hidden behind Jupiter. PICS (Pioneer Image Converter System) began to show a few spots on the screens, which gradually built up into a very distorted crescent-shaped Jupiter. "Sunrise on Jupiter," exclaimed an experimenter excitedly. "We've made it safely through periapsis." Subsequent PICS images were of a crescent Jupiter gradually decreasing in size as the spacecraft sped away out of the Jovian system. Note: used in NASA SP-349 "Pioneer Odyssey - Encounter with a Giant" fig. 5-15 and SP-446 " Pioneer - First to Jupiter, Saturn, and Beyond" fig. 5-16.

Pioneer Launch on Delta Vehi …

Title	Pioneer Launch on Delta Vehicle
Full Description	NASA launches the last in the series of interplanetary Pioneer spacecraft, Pioneer 10 from Cape Kennedy, Florida. The long-tank Delta launch vehicle placed the spacecraft in a solar orbit along the path of Earth's orbit. The spacecraft then passed inside and outside Earth's orbit, alternately speeding up and slowing down relative to Earth. The Delta launch vehicle family started development in 1959. The Delta was composed of parts from the Thor, an intermediate-range ballistic missile, as its first stage, and the Vanguard as its second. The first Delta was launched from Cape Canaveral on May 13, 1960 and was powerful enough to deliver a 100-pound spacecraft into geostationary transfer orbit. Delta has been used to launch civil, commercial, and military satellites into orbit. For more information about Delta, please see Chapter 3 in Roger Launius and Dennis Jenkins' book To Reach the High Frontier published by The University Press of Kentucky in 2002.

Pioneer F Plaque Location

Title	Pioneer F Plaque Location
Full Description	The Pioneer F spacecraft, destined to be the first man made object to escape from the solar system into interstellar space, carries this pictorial plaque. It is designed to show scientifically educated inhabitants of some other star system, who might intercept it millions of years from now, when Pioneer was launched, from where, and by what kind of beings. (Hopefully, any aliens reading the plaque will not use this knowledge to immediately invade Earth.) The design is etched into a 6 inch by 9 inch gold-anodized aluminum plate, attached to the spacecraft's attenna support struts in a position to help shield it from erosion by interstellar dust. The radiating lines at left represents the positions of 14 pulsars, a cosmic source of radio energy, arranged to indicate our sun as the home star of our civilization. The "1-" symbols at the ends of the lines are binary numbers that represent the frequencies of these pulsars at the time of launch of Pioneer F relative of that to the hydrogen atom shown at the upper left with a "1" unity symbol. The hydrogen atom is thus used as a "universal clock," and the regular decrease in the frequencies of the pulsars will enable another civilization to determine the time that has elapsed since Pioneer F was launched. The hydrogen is also used as a "universal yardstick" for sizing the human figures and outline of the spacecraft shown on the right. The hydrogen wavelength, about 8 inches, multiplied by the binary number representing "8" shown next to the woman gives her height, 64 inches. The figures represent the type of creature that created Pioneer. The man's hand is raised in a gesture of good will. Across the bottom are the planets, ranging outward from the Sun, with the spacecraft trajectory arching away from Earth, passing Mars, and swinging by Jupiter.

Description	Global view of Venus is created from Magellan, Pioneer, and Venera data. The northern hemisphere of Venus is displayed in this global view of Venus' surface. The north pole is at the center of the image. Zero degrees, 90 degrees, 180 degrees, and 270 degrees east longitude are at the 6, 3, 12, and 9 o'clock positions, respectively, of an imaginary clock face. Magellan synthetic aperture radar mosaics from the first cycle of Magellan mapping are mapped onto a computer-simulated globe to create this image. Data gaps are filled with Pioneer-Venus orbiter data, or a constant mid-range value. Simulated color is used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The image was produced at the Jet Propulsion Laboratory (JPL) Multimission Image Processing Laboratory and is a single frame from a video released at the JPL news conference, 10-29-91.

Title	Perspective View of Ishtar Terra
Original Caption Released with Image	This perspective view of Ishtar Terra was derived from data obtained by the Pioneer Venus spacecraft's altimetry radar instrument. Ishtar viewed from the west (bottom of image) is centered at about 65 degrees north latitude and 0 degrees longitude. Ishtar (approximately equal in size to Australia) is a large plateau standing 3.3 km above the surrounding lowlands, bounded by relatively steep slopes. Rising above this plateau are three massifs: Akna Montes and Freyja Montes along the western and northwestern edge of Lakshmi Planum, and Maxwell Montes along its eastern edge. The eastern part of Ishtar, east of Maxwell, is a complex hilly terrain ~1 km lower than Lakshmi Planum that lacks the steep well-defined boundary slopes that characterize the plateau. Maxwell Montes, highest point on the planet is elevated more than 10 km (32,000 ft) above the surrounding lowlands. Color-coded altimetry shows elevations in .5 and 1 km intervals. Cool colors mark low elevations and warm colors mark high elevations

Title	Venus - Magellan Data Superimposed on Pioneer Venus Data - Devana Chasma and Phoebe Regio
Original Caption Released with Image	This image covers part of the 150 kilometer (90 mile) wide, 1 to 1.5 kilometer (0.6 to 0.9 mile) deep valley, Devana Chasma. The image is a composite of the first two orbits recorded by the Magellan spacecraft in August 1990 superimposed on Pioneer Venus topography. This image is located at the intersection of Devana Chasma and the Phoebe Regio upland. It covers a region approximately 525 by 525 kilometers (315 by 315 miles), centered 288 degrees east longitude on the equator. Devana Chasma consists of radar bright lineaments, interpreted to be fault scarps, oriented in a north-northeast direction. This part of the planet is thought to be an area where the crust is being stretched and pulled apart producing a rift valley, similar to the East African rift.

Global view of Venus from Ma …

Title	Global view of Venus from Magellan, Pioneer, and Venera data
Description	This global view of Venus, centered at 270 degrees east longitude, is a compilation of data from several sources. Magellan synthetic aperature radar mosaics from the first cycle of Magellan mapping are mapped onto a computer-simulated globe to create the image. Data gaps are filled with Pioneer-Venus orbiter data, or a constant mid-range value. Simulated color is used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The image was produced at the Jet Propulsion Laboratory (JPL) Multimission Image Processing Laboratory and is a single frame from a video released at the JPL news conference, 10-29-91. View provided by JPL with alternate number P-39225 MGN81.

Date	3/16/95
Description	This hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990-1994 Magellan mission, is centered at 270 degrees east longitude. The Magellan spacecraft imaged more than 98 percent of Venus at a resolution of about 100 meters, the effective resolution of this image is about 3 kilometers. A mosaic of the Magellan images (most with illumination from the west) forms the image base. Gaps in the Magellan coverage were filled with images from the Earth- based Arecibo radar in a region centered roughly on 0 degrees latitude and longitude, and with a neutral tone elsewhere (primarily near the south pole). The composite image was processed to improve contrast and to emphasize small features, and was color-coded to represent elevation. Gaps in the elevation data from the Magellan radar altimeter were filled with altimetry from the Venera spacecraft and the U.S. Pioneer Venus missions. An Orthographic projection was used, simulating a distant view of one hemisphere of the planet. The Magellan mission was managed for NASA by the Jet Propulsion Laboratory (JPL), Pasadena, CA. Data processed by JPL, the Massachusetts Institute of Technology, Cambridge, MA, and the U.S. Geological Survey, Flagstaff, AZ. #####

Venera 15

title	Venera 15
date	06.02.1983
description	Venera 15 and Venera 16 were a pair of dedicated radar mappers designed to extend the studies begun by the American Pioneer Venus Orbiter in constructing a detailed map of the surface down to a resolution of about 1 to 2 kilometers. For these missions, Soviet engineers lengthened the central bus of the earlier Veneras (by 1 meter), installed much larger solar batteries, and attached a large side-looking radar antenna in place of the descent lander module on the earlier spacecraft. Venera 15 carried out two midcourse corrections (on 10 June 1983 and 1 October 1983) before successfully entering orbit around Venus at 03:05 UT on 10 October. Initial orbital parameters were 1,000 x 65,000 kilometers at 87° inclination -- that is, a near-polar orbit. The spacecraft's mapping operations began six days after entering orbit over the north pole. Because of the nature of the spacecraft's orbit, the two orbiters mapped only the area from 30° north latitude to the pole -- about 115 million square kilometers -- before the mission was completed on 10 July 1984.

Space Interferometry Mission …

Description

Space Interferometry Mission The Space Interferometry Mission (SIM), scheduled for launch in 2006, will determine the positions and distances of stars several hundred times more accurately than any previous program. This accuracy will allow SIM to determine the distances to stars throughout the Galaxy and to probe nearby stars for Earth-sized planets. SIM will also pioneer a technique to block out (null) the light of bright stars to take images of the interesting areas close to the star. SIM will open a window to a new world of discoveries.

Pioneer 6

title	Pioneer 6
date	12.16.1965
description	Pioneer 6 was the first in a series of solar-orbiting, spin-stabilized, solar-cell and battery-powered satellites designed to obtain measurements on a continuing basis of interplanetary phenomena from widely separated points in space. Its experiments studied the positive ions and electrons in the solar wind, the interplanetary electron density (radio propagation experiment), solar and galactic cosmic rays, and the interplanetary magnetic field. Its main antenna was a high-gain directional antenna. The spacecraft was spin-stabilized at about 60 rpm, and the spin axis was perpendicular to the ecliptic plane and pointed toward the south ecliptic pole. By ground command, one of five bit rates, one of four data formats, and one of four operating modes could be selected. The five bit rates were 512, 256, 64, 16, and 8 bps. Three of the four data formats contained primarily scientific data and consisted of 32 seven-bit words per frame. One scientific data format was for use at the two highest bit rates. Another was for use at the three lowest bit rates. The third contained data from only the radio propagation experiment. The fourth data format contained mainly engineering data. The four operating modes were real time, telemetry store, duty cycle store, and memory readout. In the real-time mode, data were sampled and transmitted directly (without storage) as specified by the data format and bit rate selected. In the telemetry store mode, data were stored and transmitted simultaneously in the format and at the bit rate selected. In the duty-cycle store mode, a single frame of scientific data was collected and stored at a rate of 512 bps. The time interval between the collection and storage of successive frames could be varied by ground command between 2 and 17 min to provide partial data coverage for periods up to 19 h, as limited by the bit storage capacity. In the memory readout mode, data were read out at whatever bit rate was appropriate to the satellite distance from the earth. Although the spacecraft has not been regularly tracked for science data return in recent years, a successful telemetry contact was made on 8 Dec. 2000 to celebrate 35 years of continuous operation since launch.
