Peter Yee and I are pleased to announce a major addition to the SPACE
archive at NASA Ames Research Center.
There are eight CD-ROMs that contain about 16,000 images taken by
Voyager 1 and Voyager 2 on their encounters with Jupiter, Saturn and Uranus.
Images from these Voyager CD-ROMs are now available on-line at the Ames SPACE
archives. A CD-ROM drive has been installed at the Ames site allowing direct
access to the CD-ROM via anonymous ftp to ames.arc.nasa.gov (128.102.18.3).
The images are in the /pub/SPACE/CDROM directory. The plan is to rotate
the CD-ROMs on a weekly basis. The first CD-ROM currently on-line is the
Voyager Saturn Encounter, Volume 4. A new Magellan CD-ROM and three new
Neptune CD-ROMs are also available, and will be quickly be placed on-line when
Peter receives them.
The Voyager images are stored in compressed format on the CD-ROM with each
compressed image being about 220K. Source code for the decompression program,
decomp.c, is available on the CD-ROM. When the images are uncompressed, they
will be about 670K in size, so a large hard disk is recommended. An IBM PC
version of the decompression program, PCDCOMP, and an image display program
that also runs on an IBM PC computer, IMDISP, are also stored at the Ames site.
The most recent versions of the PCDCOMP (version 2.0) and IMDISP (version 5.6)
programs can obtained from pub/SPACE/SOFTWARE directory under the filename
imdisp56.zip.
The CD-ROMs are also available to the general public from the NSSDC
(National Space Science Data Center) at the Goddard Space Flight Center.
