Jupiter System Montage, Voyager Program, NASA/JPL Photo

(March 1979) Jupiter and its four planet-size moons, called the Galilean satellites, were photographed in early March 1979 by Voyager 1 and assembled into this collage. They are not to scale but are in their re... More

Voyager 1 Image of Ganymede. NASA public domain image colelction.

(March 4, 1979) Voyager 1 took this picture of Ganymede from a distance of 1.6 million miles. Ganymede is Jupiter's largest satellite with a radius of approximately 2600 kilometers, about 1.5 times that of Eart... More

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.  Voyager project is managed and controlled by Jet Propulsion Laboratory for NASA's Office of Space Science.  (JPL ref. No. P-21146) ARC-1979-A79-7029

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, and 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.

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.  Jet Propulsion Laboratory manages and controls the Voyager project for NASA's Office of Space Science. (JPL ref. No. P-21149) ARC-1979-A79-7027
