Saturn

General

1.Are data for the fields and particles experiments on Pioneer 11 and/or Voyager 1/2 available on CD-ROM for the Saturn encounter?

No. Some of these data are still being processed by the Planetary Data System's Planetary Plasma Interactions (PPI) node.
More information on CD-ROMs available from the NSSDC can be found in the NSSDC CD-ROM Catalog.URL: http://nssdc.gsfc.nasa.gov/cd-rom/

2. Are Digital Image/Terrain/Elevation Models/Maps available for the Saturnian satellites?
Low-resolution airbrush global digital image models in sinusoidal projection of the Saturninan satellites Mimas, Enceladus, Tethys, Dione, Iapetus, and Rhea are available on magnetic tape and as photoproducts from NSSDC (data sets SL-21G and SL-21H). More information on these DIMs and DIMs of other planets and satellites is available on the Digital Image Models Page.URL: http://nssdc.gsfc.nasa.gov/planetary/dims.html

Pioneer 11

1. Are any of the imaging data from Pioneer 11 available on CD-ROM from the Saturn encounters?

No. There is not currently any expected delivery on Pioneer 11 imaging data on CD-ROM.
More information on CD-ROMs available from the NSSDC can be found in the NSSDC CD-ROM Catalog.URL: http://nssdc.gsfc.nasa.gov/cd-rom/

Voyager 1 and 2

1. Why are some images missing from the Saturn flyby on the Voyager imaging CD-ROMs?

When the Voyager imaging CD-ROMs were first being produced, it was recognized that the volume of images from the Saturn encounter, if included in total, would take up many more volumes than desired. This would have included a number of poor images (with signal dropouts, etc.). Rather than delay the release of the better images, it was decided to place only the "best" of the images on the discs, resulting in Volumes 4-5 of the Voyager imaging CD-ROM set. Recently it has been decided to go back and put all of the Voyager images from the Saturn encounters on CD-ROM. These will begin with Volume 26 and will last until approximately Volume 35 of the series. These images will supercede those on the earlier volumes. These volumes are expected to begin arriving at NSSDC no earlier than September 1995.
