Complex sets of ridges and grooves are visible in this |
|
image of the Nippur Sulcus region on Jupiter's largest |
|
moon Ganymede. NASA's Galileo spacecraft imaged this |
|
region as it passed Ganymede during its second orbit |
|
through the Jovian system. The Nippur Sulcus region is an |
|
example of Bright Terrain on Ganymede which is typified |
|
by multiple sets of ridges and grooves. The intersections |
|
of these sets reveal complex age relationships. North is |
|
to the top of the picture and the sun illuminates the |
|
surface from the southeast (lower right). In this image a |
|
younger sinuous northwest-southeast trending groove set |
|
cuts through and apparently destroys the older east-west |
|
trending features on the right of the image, allowing |
|
scientists to determine the sequence of events that led |
|
to the region's formation. The area contains many impact |
|
craters. The large crater in the bottom of the image is |
|
about 12 kilometers (8 miles) in diameter. The image, |
|
centered at 51 degrees latitude and 204 degrees |
|
longitude, covers an area approximately 79 kilometers (50 |
|
miles) by 57 kilometers (36 miles) across. The resolution |
|
is 93 meters (330 feet) per picture element. The images |
|
were taken on September 6, 1996 at a range of 9,971 |
|
kilometers (6,232 miles) by the solid state imaging (CCD) |
|
system on NASA's Galileo spacecraft. The Jet Propulsion |
|
Laboratory, Pasadena, CA manages the Galileo mission for |
|
NASA's Office of Space Science, Washington, DC. JPL is an |
|
operating division of California Institute of Technology |
|
(Caltech). This image and other images and data received |
|
from Galileo are posted on the World Wide Web, on the |
