  Description:

    Abstract:

      Ganymede is the third of the four Galilean satellites of

      Jupiter. It is also the largest (radius of 2,631 km).

      Models for the interior structure that are constrained by

      distance from the Sun and a mean specific gravity of 1.93

      indicate that about half of Ganymede’sc mass consists of

      water ices (Cassen and others, 1982). Spectral and

      photometric properties suggest that perhaps as much as 90

      percent of Ganymede’s surface is water ice (Pilcher and

      others, 1972); the remainder is inferred to be silicates

      (Pollack and others, 1978; Sill and Clark, 1982; Clark and

      others, 1986). Although the surface of Ganymede exhibits

      many complex details, it can, to first order, be divided

      into two general types of terrains on the basis of average

      albedo (Smith and others, 1979a,b; Squyres and Veverka,

      1981; Helfenstein and others, 1984). The albedo difference

      is believed related to the proportion of silicates mixed

      with the ice. Light terrain is generally riven by abundant

      long, narrow grooves. Dark terrain is generally more

      heavily cratered than light terrain and much less commonly

      cut by grooves.

    Purpose:

    Supplemental_Information:

      The map area is in the sub-Jupiter hemisphere of Ganymede.

      All images used for mapping were obtained by Voyager 1. The

      terminator was located at about long 305° when the images

      were obtained, and all coverage in Jg-2 west of about long

      60° was obtained with emission angles too large to produce

      images usable for mapping. Resolution of the primary

      mapping images ranges from 2.4 to 5.2 km/line pair; images

      covering Jg-5 are generally superior to those covering Jg-2

      (see resolution diagram). The mapped part of Jg-2 is about

      equally divided between light and dark material, whereas

      the mapped part of Jg-5 comprises approximately 25 percent

      dark material and 75 percent light material. An

      intermediate-albedo transitional unit occurs locally; this

      unit grouped with light materials.
