International Halley Watch Volumes 25 and 26 Available at NSSDC
Spacecraft Encounters with Halley
The final two volumes, 25 and 26, of the International Halley
Watch CD-ROM set are now available at NSSDC. These volumes
contain the images and data acquired by the various spacecraft
sent to rendezvous with comets P/Halley and P/Giacobini-Zinner.
The earlier 24 volumes contained remote data only. The spacecraft
represented on these volumes are Giotto, Sakigake, Suisei,
Vega 1, Vega 2, and ICE. A
of the experiments and data covered on these two volumes is
also available. The images at the top of the page show Vega 1,
Giotto, and Vega 2 images, respectively, of Halley's Comet.
These and other
images of comet Halley
from the CD-ROMs are available.
The volumes are sold together as a set. Volume 25 contains selected
measurements and images of comet P/Halley from the
, and the
missions spanning 3 - 15 March 1986.
Volume 26 holds measurements and images of P/Halley from the
missions spanning 27 February to 10 March, 1986, and of P/Giacobini-Zinner
mission, 8 - 14 September, 1985. A User's Guide is included in the set.
Images and tables on the disk are archived in the Flexible Image
Transport System (FITS) format. The images can be retrieved on
DOS machines using the
software, and on Macintosh using the FITS
shareware, both available online at NSSDC. The IHW CD-ROMs were
assembled under the auspices of the
PDS Small Bodies Node at the University of Maryland.
On-line access to the CD-ROMs
is available there.
