NASA's Voyager 2 spacecraft flew by Triton, a moon of Neptune, in the summer of 1989. Dr. Paul Schenk, a scientist at the Lunar and Planetary Institute in Houston, used Voyager data to construct the best-ever global color map of Triton.
Several craters are seen on the surface of 1985U1, one of several small moons of Uranus discovered by NASA's Voyager 2. The spacecraft acquired this single image, the only
close-up it obtained of any of the new moons, on Jan. 24, 1986.
NASA's Voyager 2 obtained this view of Saturn's moon Tethys on Aug.25, 1981, from a distance of 540,000 kilometers (335,000 miles). It shows the numerous impact craters and fault valleys of a very ancient surface.
This is NASA's Voyager 1 picture of Callisto, the outermost Galilean satellite, taken Feb. 28, 1980. Callisto is the darkest of the Galilean satellites but is still nearly twice as bright as the Earth's Moon.
This picture was taken on March 4, 1979 at 2:30 A.M. PST by NASA's Voyager 1 from a distance of 2.6 million kilometers (1.6 million miles). Ganymede is Jupiter's largest satellite with a radius of about 2600 kilometers, about 1.5 times that of our Moon.
This picture of Io, the innermost Galilean satellite, was taken by NASA's Voyager 1 on the morning of March 5, 1979 at a range of 377,000 kilometers (226,200 miles). The smallest features visible are about 10 kilometers (6 miles) across.
This photo of Jupiter was taken by NASA's Voyager 1 on the evening of March 1, 1979, from a distance of 2.7 million miles (4.3 million kilometers). The photo shows Jupiter's Great Red Spot (top) and one of the white ovals.
Special processing has brought out surface detail in NASA's Voyager 2 image focusing on the large crater on Tethys. The spacecraft took this photograph Aug. 25, 1981, when it was 826,000 kilometers (513,000 miles) from the icy moon of Saturn
This photograph taken on Aug. 26, 1981, from NASA's Voyager 2 of Tethys shows objects about 5 kilometers (3 miles) in size and is one of the best images of the Saturnian satellite returned by the spacecraft or its predecessor, Voyager 1.
This image of the Jovian moon Europa was taken by NASA's Voyager 2 on July 9, 1979, as the spacecraft passed within 225,000 kilometers. This image was taken along the evening terminator, which best shows the surface topography of complex narrow ridges.
