Images of Jupiter, Saturn, Uranus, Neptune, and their rings and satellites (PDS)

NSSDCA ID: PSPA-00191

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1979-01-04 to 1989-09-29

Description

This contains the complete collection Voyager 1 and 2 images produced during their flybys of Jupiter, Saturn, Uranus, and Neptune. Some of the discs (Jupiter and Saturn) were originally produced as a short set of selected images from the flybys, but have been subsequently superseded with more complete collections.

Volumes 1-12

These discs are organized chronologically, with the first disc consisting primarily of pre-encounter images and the last consisting primarily of post-encounter images. Each disc contains directories organized by the object observed (e.g., Neptune, rings, a particular satellite) or for calibration or unclassifiable images. If there are more than 100 images of a particular object on the disc, the images are further divided into subdirectories based upon their image number. The images are the full-resolution (800 pixels by 800 scan lines) digital images returned by the Voyager Imaging Science Subsystem (ISS) cameras. No additional processing has been performed to enhance the images. The full-resolution images are compressed to permit more data to be stored on each volume. Decompression software for several platforms (VAX/VMS, IBM PC, and Macintosh) in several programming languages is available on the discs. The Macintosh decompression software is provided as a binhexed archive. The last volume in each subset (volumes 3, 5, 8, 12) also contains all of the images found on all previous discs in a browse format. Browse images consist of every fourth pixel of every fourth scan line, resulting in an image which is 200 pixels by 200 scan lines. These browse images are not stored in a compressed format and so can be used by software to locate quickly an image of interest prior to decompressing the full-resolution image. Browse images are located within a separate directory on the disc, with individual subdirectories based on the objects observed below that.

Discs 4-8 of this set, which contained selected images from the Jupiter and Saturn flybys, have been superseded by Volumes 13 and higher, which contain the complete collection of images of those flybys.

Volumes 13+

Discs 13+ differ from the earlier discs not only in the completeness of the images, but also in the disc structure. The earlier Voyager CD- ROMs (Vols. 1-12) consisted primarily of compressed images with specific volumes (3, 5, 8,and 12) reserved for uncompressed browse images of all of the images from the volumes relevant to a particular encounter. Beginning with Volume 13, the browse images for that particular disc are co-resident with the full-resolution compressed images. The discs are organized chronologically. Each disc contains directories organized by the object observed (e.g., Jupiter, rings, a particular satellite) or for calibration or unclassifiable images. If there are more than 100 images of a particular object on the disc, the images are further divided into subdirectories based upon their image number. The images are the full-resolution (800 pixels x 800 scan lines) digital images. No additional processing has been performed to enhance the images. The full-resolution images are compressed to permit more data to be stored on each volume. Decompression software for several platforms (VAX/VMS, IBM PC, Macintosh, and UNIX) in several programming languages is available on the discs. (NB: Decompression software for other platforms can be obtained from other sources, including the discs for the other Voyager encounters.)

Starting with Volume 13, each CD-ROM contains their own browse images. Browse images are located within a separate directory on the disc, with individual subdirectories based on the objects observed below that.
