That's perfectly fine. I understand that life can get us away from hobbies or other activities.

orbital xyz-trajectory for Pioneer Venus Orbiter around Venus was completed from the date of its insertion in the orbit December 4 till July 4/ 1979 12:00:00 UTC... after this date till end of mission I will use the orbital elements where Pericenter is about 176 km from the planet, Apocenter is about 66 638 km... Inclination is 105,0 degrees... Eccentricity is 0,8422... and other elements for the epoch JD 2444059,00197...

Very nice! I wonder if Hipparcos is over the horizon as well soon!

for making model from the zero need a lot of pictures of spacecraft... time... and trajectory for add-on! :smile: :smile: :smile:

but okay... I can make any trajectories... and I can make models of spacecrafts... a lot of pictures I can find in internet but I will be very grateful if the members of Celestia forum will help me in this...

I'll be more than glad to help you with Hipparcos in any way possible. :smile:

Thanks SpaceFanatic64... :smile: I will start project Hipparcos after I finish with Luna 2 and Luna 3... the models of these spacecrafts are ready at 99%... need a trajectories for add-ons... can you imagine, Luna 2 should to impact near the place at Moon as it was in reality... I will accept an error not more than 50 km only... :think:
With trajectory for Luna 3 no a big problems...

Alexey Nesterov (toutatis) presents a new model and add-on for Celestia... *** Pioneer Venus Orbiter ***

I thank you for taking my request. In fact, I'll probably never get rid of this addon! Pioneer Venus Multiprobe, with detaching probes, coming soon! :smile:

Yes, your request SpaceFanatic64... :smile: :smile: :smile:
watch how changes the orbital frame reference on December 4, when this spacecraft was in the process of entering into orbit around Venus... I like this model and add-on... I have learned a lot of new things in modeling and in making trajectories... :biggrin:

It is so good, I have informed Art Blos if he can add this into Celestia Origin. But he has not responded yet.

Beautiful achievement!
The progress of the mission is remarkably described even if I do not master BodyFrame and Timeline which are poorly explained in the wikipedia pages for Celestia. This deserves a lesson on the subject.

Added after 2 hours 1 minute:
Toutatis say
Fobos-Grunt... Job done!

You have never published the result. :sad:

Fobos-Grunt was done at my personal request. Here is an improved version that will be included in the next release CO.
