Celestia Forums

Versions of Celestia before v1.5.0 use UTC to calculate times and positions. Unfortunately, UTC includes "leap seconds" in order to stay aligned with the Earth's varying rotation. Leap seconds happen essentially randomly, when they are needed. Although Celestia does incorporate a table of ...

The solar panels of orbital spacecrafts looks like the atmosphere of the planets, around they rotate... if the satellite is on Earth's orbit, then they reflect more of the blue color ... around the moon is the color of the moon ... that is simple ...

Deep Space Climate Observatory Deep Space Climate Observatory (DSCOVR; formerly known as Triana, unofficially known as GoreSat) is a NOAA space weather and Earth observation satellite.

Thank you for your positive reply about my request for Launch pads from Orbiter, and I believe it's not an easy task, but if I can help you with textures (sorry, I'm unable to help in modelling), I'm here.

Thank you very much Goofy...

I do not have confidence that the updated model corresponds to the original.

Well, there are many options...

New Swift Observatory model...

Asteroid 1999 JU3 (RYUGU)... Sampled orbit... Timeline from 2018-04-01 to 2020-12-01... am sorry... some correction in SSC-file for Ryugu... Texture, Radius, Albedo... "162173 Ryugu:Ryugu:1999 JU3" "Sol" { Class "asteroid" Texture "darkasteroid.jpg" Mesh "...

This asteroid is in Project "Celestia Origin", release dated April 30, 2018

Ow... Then I have it...

In my Celestia 5000 asteroids... but I still did not visited each of them...

Added after 17 minutes 31 seconds:
Now we need a sampled orbit for Ryugu... because of Hayabusa-2

Hi, Art Blos... are you done with 1999 JU3 (Ryugu)???

I know nothing about 3D modelling, so I don't know if this is possible or if it's a too complex and difficult task, but I hope it could be done by you... :help: Thank you for all your work, appreciated. Hi Goofy... Yes, it's possible... I can convert all .msh files from "Orbiter" to 3ds f...

Now I will start work with "Swift Telescope" ... It's need to fix visual defects and also need to add some parts to the model that are missing in the original model ...

Here a model untreated for Hayabusa (1 or 2 ?)
format Colloda .dae
source : 3D Warehouse

format .dae is importable to Blender

Hayabusa-1...

Hayabusa-2 add-on with a Sampled Trajectory (XYZV-file... ) data from "HORIZONS" (NASA... JPL...)

When you publish modified models which originated from other sources, it would be appropriate to include credits saying where you got them and, if known, who created them. Yes, you are right Selden... but the most of them not a ready made models even... and there more work to prepare them for visua...

All 3 models of Hayabusa-2 are ready for use in Celestia... the orbit parameters in this add-on is just for testing... for real orbit need XYZV-file...

Added after 4 minutes 1 second:
Hayabusa-2 models...

Hayabusa-2 testing...

I think tomorrow all 4 models will be ready...

Changes in the design and texture are visible, the quality has improved. Thanks Croc... :smile: Surely now Landsat looks pretty nice. :smile: If I can, I suggest you a bit more "convolute" or "wizened" foil, and possibly with a less reddish color, as you see in this image it loo...

was added the impactor...

New Landsat 7 add-on... I fixed all visual defects of the old model... and corrected SSC-file...
