Post subject:  the planets

well i am a bit undecided so for now each planet is going to have a thread
BUT
the ssc works a LOT better if it is only ONE file and all the planets are in it
"1.Barycenters.ssc"
"SolarSystem.SPICE.ssc"

there is a read order that needs to be thought about
Linux OS's read a list of files in a specific order
( then add to that a bit of a BUG in celestia and ssc file names can get a bit complicated )
--------------------------------
one would think it is
1.ssc
2.ssc
3.ssc
4.ssc
but that would be wrong
1.ssc
4.ssc
2.ssc
3.ssc
is the order for this list of 4
----------------------------------------


posting it this way will make Jupiter and Saturn LONG threads but , what the hay .

A few files are going to be needed
You already have the "de430.bsp" from the barycenter
ftp://naif.jpl.nasa.gov/pub/naif/generi ... k/planets/
now the planets ( NOT MOONS ! ,some of them will need different files ) also have a "SpiceRotation"
this needs the rotation model "pck00010.tpc" and the LEAP SECOND file " "naif0011.tls"
ftp://naif.jpl.nasa.gov/pub/naif/generic_kernels/pck/
-- pck00010.tpc --
the .tpc file is a text file and WORTH A READ !!!
things like the body radii are defined in it

ftp://naif.jpl.nasa.gov/pub/naif/generic_kernels/lsk/
-- naif0011.tls --

most of this is going to be repeated in the individual planet sections


the Google drive folder with each planet ssc
it is advisable to make just one large ' SolarSystem.SPICE.ssc ' file

https://drive.google.com/folderview?id= ... sp=sharing
---- warning ----
google keeps changing things
now any new file i upload is NOT readable online
so Cassini and Saturn ARE NOT readable you can ONLY download the ssc
-- i did NOT make any change to the settings
