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.

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. This color photo was assembled at Jet Propulsion Laboratory's Image Processing Lab from there black and white images taken through filters.

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

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.

These four pictures of Jupiter's Great Red Spot were taken Feb. 2 and 3, 1979, when Voyager 1 was about 31 million kilometers (19.4 million miles) from Jupiter. The pictures were taken one Jupiter rotation apart, so that together they depict four days in the life of the centuries-old Red Spot. The pictures clearly demonstrate changes in circulation around the Red Spot during the 40-hour period. The photos were taken through a blue filter.

Callisto , The outermost Galilean Satellite , or Moon , of Jupiter, as taken by Voyager I . Range : About 7 Million km (5 Million miles) . Callisto, the darkest of the Galilean Satellites, still nearly twice as bright as the Earth's Moon, is seen here from the face that always faces Jupiter. All of the Galilean Satellites always show the same face to Jupiter, as the Earth's moon does to Earth. The Surface shows a mottled appearance of bright and dark patches. The former reminds scientists of rayed or bright haloed craters, similiar to those seen on earth's Moon.

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-21744 C Range: 4.2 million kilometers (2.6 million miles) In this image of Europa acquired by Voyager 2, global scale dark streaks are becoming visible. Europa, the size of the earth's moon, is apparently covered by water ice as indicated by ground based spectrometers and its brightness. The central longitude of this view is 235Â° west. Bright rayed impact craters which are abundant on ancient Ganymede and Callisto would easily be visible at this range. The suggestion is that Europa's surface is young and that the streaks are reflections of currently active internal dynamic processes. ARC-1979-AC79-7078

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

Range : 3.4 million km This pair of images shows two of the long-lived white oval clouds which have resided in the Jovian southern hemisphere for nearly 40 years. The upper picture shows the cloud that is at a longitude west of the Great Red Spot, and the lower frame, the cloud at a longitude east of this feature. The third oval is currently just south of the Great Red Spot. The clouds show very similar internal structures. To the east of each of them, recirculation currents are clearly seen. In the lower frame, a similar structure is seen to the west of the cloud. Although a recirculation current is associated with the upper western region of the cloud, it is further away from this feature and not seen in the image. This photo was taken by Voyager 2.

P-21738 BW Raange: 4.76 million kilometers (2.9 million miles) This Voyager 2 picture of Io was taken in ultraviolet light and shows one of the volcanic eruption plumes first photographed by Voyager 1. (the bright spot on the right limb) The plume is more than 200 kilometers (124 miles) high. The volcano apparently has been erupting since it was observed by Voyager 1 in March, 1979. This suggests that the volcanoes on Io probably are in continuous eruption. ARC-1979-A79-7073

Range : 1,094,666 km (677,000 mi.) This false color picture of Callisto was taken by Voyager 2 and is centered on 11 degrees N and 171 degrees W. This rendition uses an ultraviolet image for the blue component. Because the surface displays regional contrast in UV, variations in surface materials are apparent. Notice in particular the dark blue haloes which surround bright craters in the eastern hemisphere. The surface of Callisto is the most heavily cratered of the Galilean satellites and resembles ancient heavily cratered terrains on the moon, Mercury and Mars. The bright areas are ejecta thrown out by relatively young impact craters. A large ringed structure, probably an impact basin, is shown in the upper left part of the picture. The color version of this picture was constructed by compositing black and white images taken through the ultraviolet, clear and orange filters. ARC-1979-AC79-7104

Scientists believe that heavily cratered terrains like these on Callisto are indicative of ancient planetary surfaces. Voyager 2 mapped the side of Callisto not seen by Voyager 1.

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

Notable are the very bright rayed craters that probably are very young. Near the limb is a giant probable impact structure. Several large structures were discovered by Voyager 1. This one is smaller than the largest one found by Voyager 1 but is more clearly shown. About 15 concentric rings surround the bright central spot. Many hundreds of moderate sized impacts are also seen, a few with bright radial ray patterns. The limb is very smooth confirming that no high topography has been seen on the satellite, and observation consistent with its icy composition. ARC-1979-A79-7080

Range : 225,000 kilometers (140,625 miles) This image of the Jovian moon Europa was taken by Voyager 2 along the evening terminator, which best shows the surface topography of complex narrow ridges, seen as curved bright streaks, 5 to 10 kilometers wide, and typically 100 kilometers in length. The area shown is about 600 by 800 kilometers, and the smallest features visible are about 4 kilometers in size. Also visable are dark bands, more diffused in character, 20 to 40 kilometers wide and hundreds to thousands of kilometers in length. A few features are suggestive of impact craters but are rare, indication that the surface thought to be dominantly ice is still active, perhaps warmed by tidal heating like Io. The larger icy satellites, Callisto and Ganymede, are evidently colder with much more rigid crusts and ancient impact craters. The complex intersection of dark markings and bright ridges suggest that the surface has been fractured and material from beneath has welled up to fill the cracks. ARC-1979-A79-7093

P-21758 BW Range: 246,000 kilometers (152,000 miles) This picture by Voyager 2 is the first close look ever obtained of Jupiter's satellite, Europa. The linear crack-like features had been seen from a much greater distance by Voyager 1 but this image provides a resolution of about four kilometers (2.5 miles). The complicated linear features appear even more like cracks or huge fractures in these images. Also seen are somewhat darker mottled regions which appear to have a slightly pitted appearance, perhaps due to small scale craters. No large craters (more than five kilometers in diameter) are easily identifiable in the Europa photographs to date, suggesting that this satellite has a young surface relative to Ganymede and Callisto, although not perhaps as young as Io's. Various models for Europa's structure will be tested during analysis of these images, including the possibility that the surface is a thin ice crust overlying water or softer ice and that the fracture systems seen are breaks in that crust. Resurfacing mechanisms such as production of fresh ice or snow along the cracks and cold glacier-like flows are being considered as possibilities for removing evidence of impact events. Europa thus appears to truly be a satellite with many properties intermediate between Ganymede and Io. ARC-1979-A79-7087

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-21756 BW only Range: 120,000 km (right) 169,000 km (left) Right: In the foreground of this picture taken by Voyager 2, the part of the surface of Ganymede shown is the typical grooved terrain as seen by Voyager 1. It consists of mutually intersecting bands of closely-spaced, parallel ridges and grooves. In the background is newly-cratered dark terrain across which can be traced several widely spaced parellel linear features. When viewed from a distance the line features appear to trace broad circular areas. The features resemble the circular ridges on Callisto that surround an almost complete annealed impact basin. The feature on Ganymede may be of similar origin but all traces of the impact itself have been destroyed. Left: This picture of Ganymede shows that the dark contrast terrain is separated by bright bands of grooved terain. The band of closely spaced linear grooves in the foreground is 150 km across and appears to be offset by another narrow band at right angles, as though by faulting. A variety of ray patterns are seen around the craters. One is in the left of the picture, it has prominent dark rays around an inner bright halo. Other craters have dark haloes; others have diffuse bright rays. The variation of albedo patterns around the craters may be indications of layering in the surface materials. The intensity of the craters suggests the dark areas are extremely old. The bright grooved terrain is less cratered and probably somewhat younger. ARC-1979-A79-7085

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 : 241,000km (150,600 mi.). This black and white image of Europa, smallest of Jupiter's four Galilean satellites, was acquired by Voyager 2. Europa, the brightest of the Galiliean satellites, has a density slightly less than Io, suggesting it has a substantial quantity of water. Scientists previously speculated that the water must have cooled from the interior and formed a mantle of ice perhaps 100 km thick. The complex patterns on its surface suggest that the icy surface was fractured, and that the cracks filled with dark material from below. Very few impact craters are visible on the surface, suggesting that active processes on the surface are still modifying Europa. The tectonic pattern seen on its surface differs drastically from the fault systems seen on Ganymede where pieces of the crust have moved relative to each other. On Europa, the crust evidently fractures but the pieces remain in roughly their original position. ARC-1979-A79-7092

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

The arms of the ring are cut off on each sideby the planet's shadow as they approach the brightly outlined disk. The night side of the planet appears completly dark in this reproduction, but later will be specially reprocessed to search for evidence of lightning sorms and auroras.

The cylindrical projections of Jupiter, representing both Voyager 1 (top) and Voyager 2 (bottom), are presented in this comparison. The top picture extends 400 degrees longitude to 0 degrees (right edge). It is aligned with the lower image so that the longitude scale is correct for both frames. The comparison between the pictures shows the relative motions of features in Jupiter's atmosphere. It can be seen that the Great Red Spot has moved westward and the white oval features eastward during the time between the acquisition of these pictures. Regulare plume patterns are equidistant around the northern edge of the equator, while a train of small spots has moved eastward at approxiamately 80 degrees south latitude. In addition to these relative motions, significant changes are evident in the recirculation flow east of the Great Red Spot, in the disturbed region west of the Greast Red Spot, and as seen in the brightening of material spreading into the equatorial region from the more southerly latitudes.

Range : 312, 000 kilometers (195,000 miles) This photo of Ganymede (Ice Giant) was taken from Voyager 2 and shows features down to about 5 to 6 kilometers across. Different types of terrain common on Ganymede's surface are visible. The boundary of the largest region of dark ancient terrain on Ganymede can be seen to the east (right), revealing some of the light linear features which may be all that remains of a large ancient impact structure similar to the large ring structure on Callisto. The broad light regions running through the image are the typical grooved structures seen within another example of what might be evidence of large scale lateral motion in Ganymede's crust. The band of grooved terrain (about 100 kilometers wide) in this region appears to be offset by 50 kilometers or more on the left hand edge by a linear feature perpendicular to it. A feature similar to this one was previously discovered by Voyager 1. These are the first clear examples of strike-slip style faulting on any planet other than Earth. Many examples of craters of all ages can be seen in this image, ranging from fresh, bright ray craters to large, subdued circular markings thought to be the 'scars' of large ancient impacts that have been flatteded by glacier-like flows.

Range : 106,250,000 km. ( 66 million miles) P-22830C This, Voyager 1 image shows Saturn and three of its satellites. A series of dark and light cloud bands appears through high altitude haze in the northern hemisphere. Cosiderable structure can be seen in the rings. The Cassini division, between the A-ring and B-ring, is readily visible. The shadow of rings on the planet's disk can also be seeen. The three satellites visible are, left to right, Enceladus (off the left edge of rings), Dione (just below the planet), and Tethys (at right edge of frame). The spacecraft will make its closest approach, 124,200 km. (77,174 miles) abovr the cloud tops, at 3:45 pm PST on Nov. 12, 1980. Nine months later, in August 1981, Voyager 2 will encounter Saturn and then continue on to Uranus. ARC-1980-AC80-7000

Range : 76 million km. ( 47 million miles) P-22892C This, Voyager 1 image shows Saturn and five of its satellites. Saturn's largest moon, Titan, is clearly seen in the upper right corner. The smaller satellites, Dione & Tethys, are shown in the upper left corner, top and bottom respectively. Two of the innermost satellites, Mimas & Enceladus, appear to the lower right of the planet, with Mimas closest to Satun. The bright object to the left of the rings is not a moon, but an artifact of processing. Voyager 1 will make its closest approach November 12th, 1980, ata distance of 124,200 km. (77,176 mi.). this photo is just one of 17,000 images taken of Saturn, its rings, and its satellites by Voyager 1. ARC-1980-AC80-7001

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
