Photo by Voyager 1 Jupiter's satellite Io poses before the giant planet in this photo returned Jan 17, 1979 from a distance of 29 million miles (47 million kilometers). The satellite's shadow can be seen falling on the face of Jupiter at left. Io is traveling from left to right in its one-and-three-quarter-day orbit around Jupiter. Even from this great distance the image of Io shows dark poles and bright equatorial region. Voyager 1 will make its closest approach to Jupiter 174, 000 miles (280,000 kilometer) on March 5. It will then continue to Saturn in November 1980. This color photo was assembled at Jet Propulsion Laboratory's Image Processing Lab from three black and white images taken through filters. The Voyagers are managed for NASA's Office of Space Science by Jet Propulsion Laboratory. (JPL Ref: P-20946C) ARC-1979-AC79-0143-4

Photo by Voyager 1 (JPL) The spacecraft took this photo of the planet Jupiter on Jan 24, while still more than 25 million miles (40 million kilometers) away. As the spacecraft draws closer to the planet (about 1 million kilometers a day) more details are emergng in the turbulent clouds. The Great Red Spot shows prominently below center, surrounded by what scientists call a remarkably complex region of the giant planet's atmosphere. An elongated yellow cloud within the Great Red Spot is swirling around the spot's interior boundary in a counterclockwise direction with a period of a little less than six days, confirming the whirlpool-like circulation that astronomers have suspected from ground-based photographs. Ganymede, Jupiter's largest satellite, can be seen to the lower left of the planet. Ganymede is a planet-sized body larger than Mercury.

Photo by Voyager 1 (JPL) Jupiter, its Great Red Spot and three of its four largest satellites are visible in this photo taken Feb 5, 1979 by Voyager 1. The spacecraft was 28.4 million kilomters (17.5 million miles) from the planet at the time. The inner-most large satellite, Io, can be seen against Jupiter's disk. Io is distinguished by its bright, brown-yellow surface. To the right of Jupiter is the satellite Europa, also very bright but with fainter surface markings. The darkest satellite, Callisto (still nearly twice as bright as Earth's Moon), is barely visible at the bottom left of the picture. Callisto shows a bright patch in its northern hemisphere. All tThree orbit Jupiter in the equatorial plane, and appear in their present position because Voyageris above the plane. All three satellites show the same face to Jupiter always -- just as Earth's Moon always shows us the same face. In this photo we see the sides of the satellites that always face away from the planet. Jupiter's colorfully banded atmosphere displays complex patterns highlighted by the Great Red Spot, a large, circulating atmospheric disturbance. This photo was assembled from three black and white negatives by the Image Processing Lab at Jet Propulsion Laboratory. JPL manages and controls the Voyage Project for NASA's Office of Space Science.

Voyager 1 Image of Jupiter and two of its satellites (Io, left, and Europa). Io is about 350,000 kilometers (220,000 miles) above Jupiter's Great Red Spot; Europa is about 600,000 kilometers (375,000 miles) above Jupiter's clouds. Although both satellites have about the same brightness, Io's color is very different from Europa's. Io's equatorial region show two types of material -- dark orange, broken by several bright spots -- producing a mottled appearance. The poles are darker and reddish. Preliminary evidence suggests color variations within and between the polar regions. Io's surface composition is unknown, but scientists believe it may be a mixture of salts and sulfur. Erupoa is less strongly colored, although still relatively dark at short wavelengths. Markings on Eruopa are less evident that on the other satellites, although this picture shows darker regions toward the trailing half of the visible disk. Jupiter at this point is about 20 million kilometers (12.4 million miles) from the spacecraft. At this resolution (about 400 kimometers or 250 miles) there is evidence of circular motion in Jupiter's atmosphere. While the dominant large-scale motions are west-to-east, small-scale movement includes eddy-like circulation within and between the bands. (JPL ref: P-21082) ARC-1979-A79-0164-1

Range : 5 million miles (8.025 million kilometers) This is a morning shot of Ganymede, largest of Jupiter's 13 satellites. It's slightly larger than Mercury with a density about twice that of water. It's believed to be made of rock and ice with a surface of water and ice. Ganymede is 4 times brighter than our Moon with the bright spot in center of photo 5 times brighter than the Moon, and may contain more ice than surrounding areas. The bright pattern around the spot seems like ray craters on the Moon and Mercury and the area may in fact be an impact crater that has exposed fresh, underlying ice.

Range : 7 million kilometers (4.3 million miles) Io is Jupiter's innermost of the four Galilean satellites. Photo taken at 2:00 AM through an ultraviolet filter. The photo's background is part of Jupiter's disk. North is at the top and the central longitude of Io is 180 degrees. Io shows a contrasting surface with dark polar areas and many light and dark regions around the equator. This resolution of about 100 miles/160 kilometers, no topographic features, like craters, can be seen. The brighter regions may be areas containing sulfur and various salts, making Io very reflective(six times brighter thanb Earth's Moon). Io is about the same size and density as our Moon, but has followed a different evolutionary path, influenced by its closeness to Jupiter and the intense bombardment it receives from the Jovian radiation belts of energetic charged particles.

This photo of Callisto, outermost of Jupiter's four Galilean satellites, was taken a few minutes after midnight (PST) Feb. 25 by Voyager 1. The distance to Callisto was 8,023,000 kilometers (4.98 million miles). The hemisphere in this picture shows a fairly uniform surface dotted with brighter spots that are up to several hundred kilometers across. Scientists believe the spots may be impact craters but higher-resolution photos will be necessary before the features can be interpreted. Callisto is about the same size as the planet Mercury--about 5,000 kilometers (3,000 miles) in diameter. Callisto is less massive than Mercury, however, giving it a density less than twice that of water. Scientists believe Callisto, therefore, is composed of a mixture of rock and ice (up to about 50 percent by weight). Its surface is darker than those of the other Galilean satellites, but is still about twice as bright as Earth's Moon. This black-and-white photo was taken through a violet filter.

This mosaic of Jupiter was assembled from nine individual photos taken through an orange filter by Voyager 1 on Feb. 6, 1979, when the spacecraft was 4.7 million miles (7.8 million kilometers) from Jupiter. Distortion of the mosaic, especially where portions of the limb have been fitted together, is caused by rotation of the planet during the 96-second intervals between individual pictures. The large atmospheric feature just below and to the right of center is the Great Red Spot. The complex structure of the cloud formations seen over the entire planet gives some hint of the equally complex motions in the Voyager 1 time-lapse photography. The smallest atomospheric features seen in this view are approximately 85 miles (140 kilometers) across.

P-21739 BW Range: 4.7 million kilometers (2.9 million miles) This picture of Io was taken as Voyager 2 closes in on the Jovian system. Scientists are studying these distant views of Io for evidences of changes since Voyager 1 observations in March of 79. Voyager 1 discovered that Io, the innermost of the Galilean satellites, is the most volcanically active body yet seen in the solar system, surpassing even earth. In this picture, the first volcano discovered by Voyager 1 is again visible in the lower left portion of the disk as a dark oval with a dark spot in the center. In March, this volcano appeared as a heart-shaped marking, not a symmetrical oval. Scientists believe that the non-symmetric markings earlier resulted from a constriction in the mouth of the volcanic vent causing erupting material to extrude preferentially in certain directions. Apparently, the volcanic eruptive activity, which sends material to altitudes of 280 kilometers (175 miles) or more above this volcano, has changed the vent geometry or dislodged an obstruction. Such changes in the form of eruptive fountains are common in terrestial volcanos, although on a much smaller scale than on Io. ARC-1979-A79-7074

P-21745 BW Range: 1.1 million miles (675,000 miles) This image of Callisto taken by Voyager 2 was enhanced to reveal detail in the scene. Voyager 1's high resolution coverage was of the hemisphere just over the right-hand (eastern) horizon, and the large ring structure discovered by Voyager 1 is just over the eastern limb. This image shows yet another ring structure in the upper part of the picture. Callisto exhibits some of the most ancient terrain seen on any of the satellites. Scientists think Callisto's surface is a mixture of ice and rock dating back to the final stages of planetary accretion (over 4 billion years ago) when the surface was pockmarked by a torrential bombardment of meteorites. Younger craters show as bright spots, probably because they expose fresh ice and frost. ARC-1979-A79-7079

This picture, taken by Voyager 2, illustrates well the light, bluish regions near the north and south poles. It is known that there is exposed water ice on the surface of Ganymede, and pehaps these polar caps are composed of a light covering of water ice or frost. Voyager 2 will pass within 63,000 kilometers (39,000 miles) of Ganymede. ARC-1979-AC79-7082

Range : 1 million kilometers Voyager 2 completed a dramatic 10 hour time lapse photo sequence to monitor the active volcanos on Jupiter's moon Io following the spacecraft's closest approach to Jupiter. This picture is one of about 200 images that will be used to generate a time lapse motion picture to illustrate Io's volcanic activity. On the bright limb, two of the plumes (P-5 & P-6) discovered in March by Voyager 1 are again visible. The plumes are spewing materials to a height of about 100 kilometers. ARC-1979-A79-7094

P-21751 C Range: 1.2 million kilometers This Voyager 2 color photo of Ganymede, the largest Galilean satellite, shows a large dark circular feature about 3200 kilometers in diameter with narrow closely-spaced light bands traversing its surface. The bright spots dotting the surface are relatively recent impact craters, while the lighter circular areas may be older impact areas. The light branching bands are ridged and grooved terrain first seen on Voyager 1 and are younger than the more heavily cratered dark regions. The nature of the brightish region covering the northern part of the dark circular fature is uncertain, but it may be some type of condensate. Most of the features seen on the surface of Ganymede are probably both internal and external responses of the very thick icy layer which comprises the crust of this satellite. ARC-1979-AC79-7083

P-21757 BW Range: 2 million kilometers (1.25 million miles) Jupiter's thin ring of particles was photographed by Voyager 2 on its approach to the giant planet. The spacecraft was 2.5Â° above the plane of the ring. Segments of both sides of the faint ring were captured in this picture. The ring was first photographed in an edge-on configuration by Voyager 1 and was measured then to have a radial extent of about 55, 000 kilometers (34,000 miles) from Jupiter's cloud tops. With this picture, it is possible to determine that the ring is much narrower radially than the individual rings of Saturn. This image has had an extreme contrast enhancement process applied to it which brought out some white blotches in the central region and makes the ring appear discontinuous and non-uniform in brightness. These effects are all artifacts of the processing. ARC-1979-A79-7086

Range : 1.2 million kilometers (750,000 miles) This picture of Io is one of the last sequence of 'volcano watch' pictures planned as a time lapse study of the nearest of Jupiter's Galilean satellites. The sunlit crescent of Io is seen at the left, and the night side illuminated by light reflected from Jupiter can also be seen. Three volcanic eruption plumes are visible on the limb. All three were previously seen by Voyager 1. On the bright limb Plume 5 (upper) and Plume 6 (lower) are about 100 km high, while Plume 2 on the dark limb is about 185 km high and 325 km wide. The dimensions of Plume 2 are about 1 1/2 times greater than during the Boyager 1 encounter, indicating that the intensity of the eruptions has increased during the four-month time interval between the Boyager encounters. The three volcanic eruptions and at least three others have apparently been active at roughly the same intesity or greater for a period of at least four months. ARC-1979-A79-7099

Range : 34 million km. ( 21.1 million miles) P-22993C This Voyager 1 photograph of Saturn was taken on the last day it could be captured within a single narrow angle camera frame as the spacecraft neared the planet for it's closest approach on Nov. 12, 1980. Dione, one of Saturn's innermost satellites, appears as three color spots just below the planet's south pole. An abundance of previously unseen detail is apparent in the rings. For example, a gap in the dark, innermst ring, C-ring or Crepe Ring, is clearly shown. Also, material is seen inside the relatively wide Cassini Division, seperating the middle, B-ring from the outermost ring, the A-ring. The Encke division is shown near the outer edge of A-ring. The detail in the ring's shadows cast on the planet is of particular interest. The broad dark band near the equator is the shadow of B-ring. The thinner, brighter line just to the south is the shadow of the less dense A-ring. ARC-1980-AC80-7003

Range : 12 million km. ( 7.56 million miles) P-23057C & BW This Voyager 1 photograph of Titan, the largest of Saturn's 14 known satellites, shows little more than the upper layers of clouds covering the moon. The orange colored haze, is believed to be composed of photochemically produced hydrocarbons, hides Titan's solid surface from Voyager's camera. Some weak shadings in the clouds are becoming visible. However, note that the satellite's southern, lower, hemisphere is brighter than the northern. It is not known whether these subtle shadings are on the surface or are due to clouds below a high haze layer. ARC-1980-AC80-7007

Range : 12.9 million km. ( 8.0 million miles ) P-29467B/W Time lapse Voyager 2 images of Uranus show the movement of two small, bright, streaky clouds, the first such features ever seen on the planet. The clouds were detected in this series of orange filtered images, over a 4.6 hour interval ( from top to bottom ). Uranus, which is tipped on its side with respect to the other planets, is rotating in a counter-clockwise direction, with its pole of rotation near the center of the disk, as are the two clouds seen here as bright streaks. The larger of the two clouds is ata lattitude of 33 degrees. The smaller cloud, seen faintly in the three lower images, lies at 26 degrees ( a lower alttitude and hence closer to the limb). Their counterclockwise periods of rotation are 16.2 and 16.9 hours, respectively. This difference implies that the lower lattitude feature is lagging behind the higher latitude feture at a speed of almost 100 meters pers second (220 mph). Latitudinal bands are also visible in these images, the faint bands, more numerous now then in previous Voyager images from longer range, are concentric with the pole rotation. thatis, they circle the planet in lines of contant latitude.

Range : 7.7 million km. ( 4.8 million miles ) P-29465 In this image captured by Voyager 2, three newly discovered satellites of Uranus can be seen orbiting outside of the nine known rings of Uranus. The outermost of the rings, the Epsilon Ring can be seen here at upper right. The largest of the three moons viewed here, 1986U1, was discovered January 3rd. it is an estimated 90 km. ( 55 mi. ) across and its orbits Uranus every 12 hours, 19 minutes ata distance of 66,090 km. ( 41,040 mi.) from the planets center. the other two moons are slightly smaller, 1986U3 orbits every 11 hours, 6 minutes at 61,750 km. ( 38,350 mi.),1986U4 every 13 hours, 24 minutes at 69,920 km. ( 43,420 mi.). They were dicovered on January 9th and 13th, respectively. Long exposures were required to bring out these small objects. As a result of the relative motions of the spacecraft and the moons, they appear slightly elongated. ARC-1981-A86-7005

Range : 4.1 million km. ( 2.5 million miles ) P-29466B/W Voyager 2 has discovered two 'shepard' satellites associated with the rings of Uranus. The two moons, designated 1986U7 and 1986U8, are seen here on either side of the bright Epsilon Ring. All nine of the known Uranian rings are visible here. The image was proccessed to enhance narrow features. The Epsilon Ring appears surrounded by a dark halo as a result of this proccessing. Occasional blips seen on the ring are also artifacts. Lying inward from the Epsilon Ring are the Delta, Gamma, and Eta Rings; then the Beta abd Alpha Rings; and finally, the barely visible 4, 5, and 6 Rings. The rings have been studied since their discovery in 1977, through observations of how they diminish the light of stars they pass in front of. This image is the first direct observationn of all nine rings in reflected sunlight. They range in width from about 100 km. (60 mi.) at the widest part of the Epsilon Ring to only a few kilometers for most of the others. The discovery of the two ring moons 1986U7 and 1986U8 is a major advance in our understanding of the structure of the Uranian rings and is in good agreement with theoretical predictions of how these narrow rings are kept from spreading out. Based on likely surface brightness properties, the moons are of roughly 20 and 30 km. diameter, respectively. ARC-1981-A86-7006
