Try this, assuming you're using a spherical projection map:

#declare moon_tex = texture {
pigment {
  image_map {
    jpeg "moon_usgs.jpg" // the file to read (iff/tga/gif/png/jpeg/tiff/sys)
    map_type 1        // 0=planar, 1=spherical, 2=cylindrical, 5=torus
    interpolate 2     // 0=none, 1=linear, 2=bilinear, 4=normalized distance
  } // image_map
}
  normal {
    bump_map { // uses image color or index as bumpiness
      jpeg "moonbump_pixelemporium.jpg" // the file to read
      map_type 1        // 0=planar, 1=spherical, 2=cylindrical, 5=torus
      interpolate 2     // 0=none, 1=linear, 2=bilinear, 4=normalized
distance
      bump_size 1     // 0...3
    } // bump_map
  }
}
