Europa , the smallest of the Galilean satellites, or Moons , of Jupiter , is seen here as taken by Voyager 1. Range : 2 million km (1.2 million miles) is centered at about the 300 degree Meridian. The bright areas are probably ice deposits, while the dark may be rocky surface or areas of more patchy ice distribution. Most unusual features are systems of linear structures crossing the surface in various directions. Of these, some of which are over 1000 km. long , & 2 or 3 hundred km. wide, may be faults which have disrupted the surface. ARC-1979-AC79-7003

Range : top- 86,000 miles bottom- 192,000 mi. These two close-ups of Ganymede, the largest of Jupiter's 13 moons, show different views of the largest block of dark, heavily cratered terrain. The bottom image shows objects 3 or 4 miles across, with resolution of about 1.5 miles. The light, linear stripes recurring across the dark region resemble the outer rings of the large ring structure around Callisto. If these features are related to an ancient ring structure formed by a large impact, their small curvature suggests that the original structure was even larger than one seen on Callisto. There is no apparent trace now of the center of this suggested structure, which must have been destroyed by the resurfacing evident over most of Ganymede in the grooved terrain. Another interpretation is that these features are not impact-related rings, but rather internally produced fractures crossing the dark terrain, similiar to the grooved bands. ARC-1979-A79-7107

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

P-29521 BW Range: 557,000 kilometers ( 346, 000 miles) The southern hemisphere of Umbriel displays heavy cratering in this Voyager 2 image. This frame, taken through the clear-filter of Voyager's narrow-angle camera, is the most detailed image of Umbriel, with a resolution of about 10 km (6 mi). Umbriel is the darkest of Uranus' larger moons and the one that appears to have experienced the lowest level of geological activity. It has a diameter of about 1,200 km (750 mi) and reflects only 16 percent of the light striking its surface; in the latter respect, Umbriel is similiar to lunar highland areas. Umbriel is heavily cratered but lacks the numerous bright-ray craters seen on the other large Uranian satellites; this results in a relatively uniform surface albedo (reflectivity). The prominent crater on the terminator (upper right) is about 110 km (70 mi) across and has a bright central peak. The strangest feature in this image (at top) is a curious bright ring, the most reflective area seen on Umbriel. The ring is about 140 km (90 mi) in diameter and lies near the satellite's equator. The nature of the ring is not known, although it might be a frost deposit, perhaps associated with an impact crater. Spots against the black background are due to 'noise' in the data.

P-29502C Range: 1.04 million kilometers (650,000 miles) This color photo of Umbriel, the darkest of Uranus' five large moons was synthesized from frames exposed with the Voyager narrow-angle camera's violet and clear filters and has a resolution of 19 km (12 mi.). Umbriel is characterized by the darkest surface and smallest brightness variations of any of the large satellites of Uranus. As seen here, the surface is also generally gray and colorless. Nevertheless, at this resolution, considerable topographic detail is revealed, showing that Umbriel's surface is covered by impact craters. The brightest spot (shown at top near the equator at approxiamately 270 ° longitude) appears as a bright ring. Its geological significance is not yet understood. Umbriel has a diameter of about 1,200 km (750 miles) and orbits 267,000 km (166,000 mi) from Uranus' center. The satellite's name, from Alexander Pope's 'Rape of the Lock,' means 'dark angel'.

P-29519BW Range: 500,000 kilometers (300,000 miles) Several craters are seen on the surface of 1986U1, one of the several small moons of Uranus discovered by Voyager 2. This single image, a clear-filtered, narrow-angle picture with a resolution of about 10 km (6 mi), is the only closeup the spacecraft obtained of any of the new moons. The moon was found December 30, 1985; it was the first and largest of nine satellites discovered by the spacecraft's cameras. This image shows 1986U1 to be a dark, nearly spherical object, with a diameter of about 150 km (90 mi); the dark surface reflects only 7 percent of the incident light. The picture was inserted into the Voyager encounter sequence late in its development.This image has had a complex history, having been recorded on the spacecraft tape recorder and first played back during the late afternoon of its recording. An antenna-pointing problem at one of the Austrailian tracking stations led to the loss of the data, so the image had to be retransmitted. ARC-1986-A86-7035

P-34540 Range: 37.3 million kilometers (23.6 million miles) This image captured by the Voyager 2 spacecraft was used to confirm the discovery of three new satellites orbiting Neptune. The 46-second exposure was taken with the narrow angle camera and shows the large globe of the planet to be severely overexposed and almost pure white in appearance. The image has been computer-processed to accentuate the new moons, which otherwise would be hard to distinguish from background noise. The satellite 1989N1, at right in this frame, was discovered by Voyager 2 in early July 1989. The new satellites confirmed later are 1989N2, 1989N3 and 1989N4. Each of the moons appears as a small streak, an effect caused by movement of the spacecraft during the long exposure. The new moons occupy nearly circular and equatorial orbits ranging from about 27,300 to 48,300 kilometers (17,000 to 30,000 miles) from Neptunes's cloud tops, and are estimated to range in diameter from about 100 to 200 kilometers (about 60 to 125 miles).

P-34669 Range : 2.6 million km. ( 1.6 million miles ) Smallest Resolvable Feature : 50 km or 31 miles These two Voyager 2 images, shot through clear filters, show the largest of the new moons of Neptune, 1989N1, discovered by Voyager. The satellite, made of dark material that reflects about 6 % of incident sunlight, has an average radius of about 200 kilometers ( 124 miles ) and an irregular shape. Its similiar appearance in the two images shows that the shape seen here is not the result of image noise or smear. This may the largest satellite in the solar system with such an irregular shape. satellite 1989N1 is slightly larger than the previously known small Neptunian moon Nereid but is very much darker.

KENNEDY SPACE CENTER, FLA. -- A seven-year journey to the ringed planet Saturn begins with the liftoff of a Titan IVB/Centaur carrying the Cassini orbiter and its attached Huygens probe. Launch occurred at 4:43 a.m. EDT, Oct. 15, from Launch Complex 40 on Cape Canaveral Air Station. After a 2.2-billion mile journey that will include two swingbys of Venus and one of Earth to gain additional velocity, the two-story tall spacecraft will arrive at Saturn in July 2004. The orbiter will circle the planet for four years, its complement of 12 scientific instruments gathering data about Saturn's atmosphere, rings and magnetosphere and conducting closeup observations of the Saturnian moons. Huygens, with a separate suite of six science instruments, will separate from Cassini to fly on a ballistic trajectory toward Titan, the only celestial body besides Earth to have an atmosphere rich in nitrogen. Scientists are eager to study further this chemical similarity in hopes of learning more about the origins of our own planet Earth. Huygens will provide the first direct sampling of Titan's atmospheric chemistry and the first detailed photographs of its surface. The Cassini mission is an international effort involving NASA, the European Space Agency (ESA) and the Italian Space Agency, Agenzia Spaziale Italiana (ASI). The Jet Propulsion Laboratory manages the U.S. contribution to the mission for NASA's Office of Space Science. The major U.S. contractor is Lockheed Martin, which provided the launch vehicle and upper stage, spacecraft propulsion module and radioisotope thermoelectric generators that will provide power for the spacecraft. The Titan IV/Centaur is a U.S. Air Force launch vehicle, and launch operations were managed by the 45th Space Wing KSC-97PC1546
