Anybody see the latest NCIS episode 'In the Dark'? Celestia is used to 'hide' a diary in a star system .. kind of cool!

All correct for now.. just one addition: Indeed, particles can be faster that the speed of light in its surrounding medium, but NEVER faster than the speed of light in vaccum. For example high energetic cosmic particles can traverse water with a speed faster then the speed of light in water.. causin...

Hello Selden,
I think I got it now correct.. at least the orbit looks alright.. the only thing left is to find out, if light time delay is in (probably not).. so I will just shift Mars by something like 20 min for its current position to find out if MRO is in front or behind Mars.

Thanks,
Achim

Hello Selden,
how to specify this? Is there a document how the SSC Files are structured? Sorry for these questions ..

Thanks,
Achim

Hello again.. checking now for the MRO orbit, I have to say it is seriously wrong. I guess some transformation of coordinates went nuts.. [img]http://www.physik.unizh.ch/~avollhar/celestia/celestia_mro.jpg[/img] Disregard MO and MGS orbits.. but according to JPL/NASA, MRO is in an orbit inclined 92....

Dea all, I GOT IT: the ~ typing helped in finding the problem, which was with missing Beginning and Ending timestamps in the SSC file.. now i can plot MRO, but getting the same problem with the undersampled orbit... but it is a big step forward! Now I am going to modify my files accordingly, so the ...

Dear Selden, hmm.. this sounds more complicated than I expected.. I am one of the 'dumb' windows users who don't even have a c compiler.. So I will have to wait for a compiled version with Spice support and a SPICE data set. That said, could maybe anybody just zip his spice-working Celestia subdir a...

Dear all,
installed again first 1.4.1. , then the recently compiled version just mentioned here and again MRO.ssc and the SPICE Files.. nothing to see.


Do I have to switch on something else?

Sorry for these stupid questions..

Hello.. I made an exact copy and paste of the MRO.ssc from symaski62 file in the post I mentioned in my question. The bsp files have the names given in the ssc file. Actuelly MRO is called Spice_MRO in the file.. but it cannot be found in Celestia. The version I installed was the precompiled verion ...

Hello all, I am trying to get together Celestia with SPICE support to have an idea when MRO is visible from earth.. so I installed a recently CVS compiled version for win32.. the executable is 2.5 MB large so I suppose the SPICE libraries are included. I created MRO.ssc and downloaded the bsp SPICE ...
