Hello,
I've just seen this
http://www.esa.int/SPECIALS/Cassini-Huygens/SEMN7LW4QWD_0.html2 new bodies between Mimas & Encelade.

I made preprimary Celestia entites for those moons using this page.

Code: Select all

"2004S1" "Sol/Saturn"
{
   Texture   "Asteroid-Dark.jpg"
   Mesh      "asteroid.cms"
   Radius   1.5

   EllipticalOrbit
   {
   Period      1.01
   SemiMajorAxis   194000
   Eccentricity   0.000
   Inclination      0.000      #
   AscendingNode   000.0      #
   ArgOfPericenter   00.0      # J2000.0
   MeanAnomaly        000.0       #
   }

   Albedo 0.7
}

"2004S2" "Sol/Saturn"
{
   Texture   "Asteroid-Dark.jpg"
   Mesh      "asteroid.cms"
   Radius   2

   EllipticalOrbit
   {
   Period      1.14
   SemiMajorAxis   211000
   Eccentricity   0.000
   Inclination      0.000      #
   AscendingNode   000.0      #
   ArgOfPericenter   00.0      # J2000.0
   MeanAnomaly        000.0       #
   }

   Albedo 0.7
}

I made their albedos 0.7 to be in between the 0.5 of Mimas and the 0.99 of Enceladus and used half of the given sizes as their radii. Lots of the elements are still 0, including the mean anomaly so they're likely to not be in the right locations in their orbits.

Oh, I forget to change Asteroid-Dark to Asteroid to fit the 0.7 albedo I used.

Hello folks, may I suggest my maneer to add items in the 'numbered moons.ssc' file:

with firstly (Brendan), default's Celestia refs -plus desactivated suggestion for other mesh or texture- and, secondly (Symasky), InfoURL line to link infos about these objects? Thanks for these preliminary installations, Jeam

Oui, la d?p?che en fran?ais, plus sp?cialement page suivante. Je voulais surtout proposer d'inclure le lien (celui d?j? cit? par exemple) dans le fichier .ssc sous la forme d'une ligne InfoURL. Cela permet d'acceder ? la page en cliquant 'info' sur l'objet lorsque Celestia tourne.
Yes, and more especially the following page for the annoucemnt in french. But I maint: to add the link in a InfoURL line in the ssc file (see my example with the first link you're provided) to access the page directly from Celestia by 'info' click on the object. Jeam
