Inner Solar System
Click on one of the planet or moon images below to bring up the interactive
Jules Verne Voyager map tool for that world, or click on the name
to bring up the corresponding Help page to see what other datasets are
available for that world. Following each Voyager portal image are
the primary science missions for the background 'texture underlay' imagery
(see Information Sources for
complete references).
Comparative Planetology
Clicking on any of the planetary images below brings up Voyager directly in
a 'view from space' orthographic projection (our "index" map), but scaled the same
for direct size comparison. For more on how to do this yourself, see below.
Each map is fully interactive in the usual ways.
Outer Solar System

How to do your own comparative planetology images
You can set up your own initial comparative planetology views. Above, for the Inner
Solar System, the mean radii of the planets are Mercury 2439 km; Venus 6051.8 km;
Earth 6378.2 km; Moon 1738 km; and Mars 3396 km. The i=1 in each
URL tells Voyager to bring up the initial image as an index map, i.e. the
orthographic 'view from space' projection. Using a normal map image width of
720 pixels (w=720) for Earth, the other widths are proportionally
determined. Note: the index map width is actually 80% of this
selected width, up to a maximum of 720 pixels = .8 x w=900. Then
the desired central longitude and latitude of each projection is given. Here we
used various longitudes (e=) and a latitude of 25°S (n=-25),
except for Mercury which is centered on the equator (n=0). We use
the default texture underlay grid (grd=1) on each, except for Earth where we use
ARC Science Simulations' Face of the Earth (grd=7) and
also turn off plate boundaries (geo=0). The opt=131072
suppresses the regional outline selection on the index map, which would be set by
default in this case to be equivalent to de=90 and dn=90.
