Galileo Solid State Imager (SSI) Data (PDS)


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

Time span: 1989-11-27 to 2002-03-30


This collection consists of all images acquired by the Galileo SSI since its launch. Included are images of Venus, the Moon, the Earth, the asteroids Gaspra, Ida, and Dactyl, Comet Shoemaker-Levy 9's impact on Jupiter, and Jupiter, its satellites and rings.

The images are in raw experiment data record, or REDR, format. In this format, the original telemetry data have been processed into raster-formatted files. Multiple versions of some files, derived from separate downlinks or playbacks, have been merged to produce a file containing the best data. Each disc contains roughly 800 images. Each image is stored as a VICAR file with an accompanying, detached PDS label for each image. Also included are documentation files which contain a description of the organization and contents of each disc and the definition of the labels.

Each CD-ROM has been formatted according to the ISO 9660 level 1 Interchange Standard and file attributes are specified by Extended Attribute Records (XARs). Thus, they can be read by a variety of computer systems (e.g., IBM, PC, Macintosh, Sun, and VAX).

Most of the discs contain a mixture of images as well as calibration images.
