International Halley Watch Volumes 25 and 26 Available at NSSDCA
Spacecraft Encounters with Halley
The final two volumes, 25 and 26, of the International Halley
Watch CD-ROM set are now available at NSSDCA. 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 IHW CD-ROMs were
assembled under the auspices of the
PDS Small Bodies Node at the University of Maryland.
