[quote="Limax7"]Hi, I'm looking the Osiris-REx spacecraft model. Can anybody help me?

OSIRIS-REx Arrival to Bennu (3-18 Dec 2018)

phpBB [media]

That is a beautiful rendering.

I am trying to create a simple show using Bennu, but any time the asteroid needs to be rendered in the field of view, from any distance, even with time paused, Celestia (Mac v1.6.1 under OS 10.10) becomes unusably sluggish. I suspect I may have a model of Bennu that is too complex.

May I ask, what model of Bennu did you use for your movie?

In the mission to the Neptune system Toutatis-6 will use a Jupiter’s gravitational assist...

Added after 22 minutes 47 seconds:
Due to the high speed of entry into the system of the planet Neptune (above than 16 km per second), most of the fuel will be consumed for the braking impulse for entering into orbit around this planet and it may be impossible to enter into orbit around Triton due to the lack of sufficient fuel ... But will be possible to make several close flybys near this moon of Neptune... and I still working to solve this task to the fullest...

Because the orbital data for the moons of Neptune in Celestia is too old (data for 1989), for more accuracy flyby in the Neptune system you need: If you use Celestia Origin, replace the file solarsys.ssc... which in "data" folder... Celestia/data/solarsys.ssc..... or just correct the orbital elements for the moons Triton and Proteus there...

Toutatis-6... the mission to the Neptune system... To be continued (because there is still a bit propellant)... I still have not decided how to finish this mission... I think it possible to enter into orbit around Triton because Toutatis-6 got a retrograd orbit like Triton and it can be made with relatively small approach velocity... but it have no second chance... or it will finish the mission in Neptune atmosphere but before will make several spans between the Neptune and its rings...

Maybe have it make a few close flybys of Larissa and then end the mission by burning in the atmosphere.

Ok, SpaceFanatic64... I will see if it possible... :smile:

Ok, good. It's nice to know that know you have the power to fill in gaps in spacecraft trajectories where data is lacking or unavailable. :smile:

I learn fast... :smile:

This mission to the Neptune system is completed... and during this week I will try to prepare Toutatis -7 is the journey to the dwarf planet Eris...

You know, I think one of the missions should be an orbiter around Pluto.

Yes, of course... Next T-8...

How many Toutatis series spacecraft will there be?

How many Toutatis series spacecraft will there be?

Ok... two more missions to outer dwarf planets in the Kuiper Belt ...these 2 mission will continue to use radioisotope thermoelectric energy source...

Toutatis-7: Earth - Jupiter (gravity assist) - Eris...
Toutatis-8: Earth - Pluto....

also missions to Mars (Toutatis-9)... to Toutatis (Toutatis-10)... to Venus (Toutatis-11)... and to Mercury (Toutatis-12)... they will use solar panels... that is all...

If someone want their own spacecraft and mission, ask....

I would request a spacecraft, but I think you already have enough work to do.
