Overview    

See Getting Started for a quick overview of the Jules Verne Voyager map tool capabilities.

For items specific to voyaging Mars, continue to read this Mars Features Help page.

To learn how to use the grd, gmt, geo, lbl, vel, mon, msc, and/or opt codes to customize a starting view, see Advanced Help: URL customizing.


Voyager Mars features     The default Mars uses a texture underlay grid grd=1 showing a Viking orbiter color composite image. Modern shape data (e.g. topography and radius) is from Mars Global Surveyor (MGS)/Mars Orbital Laser Altimeter (MOLA); one texture underlay grid is from MGS/Mars Orbiter Camera (MOC). These data and derived models can be compared with earlier (and lower resolution) ones based on Viking orbiter and the Mariner 9 flyby.

The texture underlay grids available in the [Features:] menu of Voyager: Mars are:

[Viking composite]  http://jules.unavco.org/Mars grd = 1   Viking orbiter color composite image (0.0156° resolution)
[MOLA topo: color w/ relief]  http://jules.unavco.org/Mars?grd=2 grd = 2   MGS)/MOLA color-scaled topography with shaded relief (0.0156° resolution)
