Spacecrafts for Celestia

[toutatis]

Start work with Venus-Expres model from ESA... need to make UV-mapping and texturing this model...

[gironde]

Great job, Toutatis.

I have two missions that sound like they would be good for Celestia. The Pioneer Venus Orbiter and Pioneer Venus Multiprobe. After searching through the internet, I was unable to find 3D models of the probes or trajectory data, so you may have to create them on your own.

New GAIA model... Autor of the model: ESA (European Space Agency)... Prepared this model for Celestia: toutatis (Alexey Nesterov)...

Art Blos, you might want to add this and update the Gaia Model in Celestia Origin

[toutatis]

Great job, Toutatis.

Thanks Gironde...

That's possible, if we have some data (dates of start and finish missions, distances between the goal of mission and the probes in some date of the flight , coordinates, etc...) and also the pictures of the probes...

[SpaceFanatic64]

Searching Pioneer Venus Orbiter or Pioneer Venus Multiprobe on Google images does yield decent results for pictures of the spacecraft itself.

hello Toutatis,

again a good addon !

but problem with radius :
first phase (cruise) : Radius 0.0009
second phase (orbiter) : Radius 0.002

Esa write :
"Dimensions: 1.5 x 1.8 x 1.4 m plus two solar arrays (with solar arrays extended, it measures about eight metres across)."

The radius is 0.004

[toutatis]

Thanks Gironde... Sometimes I trying to make add-ons too fast, so such small problems can happen... ...

It happens to everyone. And sometimes it is the most obvious that the mind refuses to see.

Yes,so...

Toutatis,

About his big brother, Mars-Express

the site (in French), http://www.nirgal.net/mars_express.html provides us with additional information about Mars Express.
The probe is equipped with a radar, MARSIS, capable of probing the Martian soil to a great depth.
This radar works with a triple arm antenna, 2 large arms carrying the span of the probe at 40m (radius 20m) and a smaller and perpendicular arm of 7m.

The MARSIS antenna has been deployed in several phases
May 4, 2005 (1st arm of 20m)
June 14, 2005 (2nd arm of 20m)
June 17, 2005 (3rd arm of 7m)

Can you improve your addon of September 4th, 2018 by separating the period 'cruise' without the antennas ( radius 6m) and a period 'orbiter' with the antennas (radius 20m) ?
This would require 2 models 3D

Yes Gironde... I can.. no problem... and my next work is Mars Express..
I will prepare new model from ESA website... and I can transform any models...

[gironde]

Super !

[toutatis]

[toutatis]

Making Mars Express bus by myself... model from ESA is low quality... need to prepare 3 models...

Wow! Good job! As far as I know the most detailed model of Mars Express we have so far is quite terrible.

Yes, fyr02... agree..

[gironde]

It is true. Toutatis has accustomed us to look after the details
