with the craft waking up and the minor moon meshes done

time for this

I am using a edited version of Jestr's " new_horizons_jpg_v2.zip "
http://celestiamotherlode.net/catalog/s ... don_id=913

just the cmod and some editing ( the cmod calls ALL CAP image names and file extensions )
added a new gold foil and a normalmap for the foil

still working on it

The spice data
for now it is ONLY location data.There is a NASTY problem with the rotation bc files.
they are NOT continuous and will require a new timeline entry for EACH
the 2014 file "merged_nhpc_2014_v000.bc" has 4 different segments in it
Code:
ckbrief -rel -g merged_nhpc_2014_v000.bc naif0010.tls new_horizons_0664.tsc
 
CKBRIEF -- Version 6.1.0, June 27, 2014 -- Toolkit Version N0065

you will need the bsp "nh_pred_od077.bsp"
ftp://naif.jpl.nasa.gov/pub/naif/pds/da ... /data/spk/

the Pluto/Charon spice add on is fine to define the location of the barycenter used

and this bsp file ALSO!!! has different time segments REQUIRING using a timeline
( as you can see this is going to be VERY complex to add the rotational data in )
Code:

Hi John,

I just finalized the (16k)Pluto - (8k)Charon VT texture system for celestia.Sci
(including the official matched (16k/8k) DEMs (=>dxt5nm VT normalmaps).

Question: Do you have a (tested) Spice kernel file update beyond what you posted here for New Horizonts + Pluto + Charon? Currently I use the latest 64/32bit builds (v. N0066) of CSpice. With various photos among the NH collection I was able to verify the relative orientations of Pluto and Charon near closest approach(July 14 2015).

When I am done, I'll post a summary in my Glancing at celestia.Sci thread viewtopic.php?f=11&t=910

Thanks,
Fridger

PS:
Did you post your finalized edit of Jestr's New Horizons spacecraft somewhere for download? Looks fine, notably with the new Gold foil!

still working on the reconstructed kernel for the pluto encounter
nh_recon_od117_v01.bsp

there is also a new KBO kernel for the extended mission kbo encounter

Code:

however these are a bit more noisy than the images of the foil on the spacecraft
