I'm appreciating a lot what you are doing with spacecraft models, very nice and precious job,

Anyway Thanks Goofy...

TESS again... ... Alternative add-on...

Hi Toutatis and Gironde. I'm appreciating a lot what you are doing with spacecraft models, very nice and precious job, but (there is aolways a "but", alas!) I find just a small defect in all of them: they look too much "new", just like kids new plastic toys. :weirdface: IMHO the...

Everything is works well in Celestia Origin... I use it and I like it... Problems with computers only...

Mars Atmosphere and Volatile Evolution Mission (MAVEN) is a space probe developed by NASA to study the Martian atmosphere while orbiting Mars. Mission goals include determining how the planet's atmosphere and water, presumed to have once been substantial, were lost over time... https://en.wikipedia....

it will tell me where you found the semimajoraxis because it is not in the 2 lines of Norad Satcat or how you calculate it. I calculate it from TLE... watch... let's use TLE you posted here... If (A) - semimajor axis.. then we can found it if we know only a Period (in seconds) (T) from this! A^3=μ*...

this is from the NORAD archive... TRMM: Epoch - 2457064.46157 (10/02/2015 23:04:40 UTC) Period - 0.06360739682865741446 SemiMajor Axis - 6730.3524986523755476 Eccentricity - 0.0004267 Inclination - 34.9536 Ascending of Node - 347.4797 Argument of Pericenter - 261.2269 Mean Anomaly - 158.1517

here is my last born: satellite TRMM This satellite was launched in Japan in 1997 (collaboration with Nasa) and returned to the atmosphere and was destroyed in 2015 I had a lot of trouble determining its orbit when it was active. I collected the archive of Satcat for 1997 but I had nowhere semimajo...

The Fermi Gamma-ray Space Telescope (FGRST), formerly called the Gamma-ray Large Area Space Telescope (GLAST), is a space observatory being used to perform gamma-ray astronomy observations from low Earth orbit. Its main instrument is the Large Area Telescope (LAT), with which astronomers mostly inte...

The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is a NASA asteroid study and sample-return mission. Launched on 8 September 2016, its mission is to study asteroid 101955 Bennu, a carbonaceous asteroid, and return a sample to Earth on 24 Septemb...

Next spacecraft is space observatory FERMI-GLAST... it tomorrow...

3D model of OSIRIS-REx spacecraft is ready! Now I preparing XYZV-file to show it trajectory in Celestia...

Added after 2 minutes 45 seconds:

Full-scale preparation for the new release has begun!

Cool!

I found another satellite: FootSat
launch 2018 06 14 15:00:00 utc
end of mission: 2018 07 15 15:00 utc
returned to the atmosphere and landing in Moscow (Luzhniki)
May the best win !

there are corrections for the models...

This photo clearly shows that the upper part of the TPP with gold foil, the lower part with silver foil: Thanks Croc... Let's make it too... :smile: new spacecraft : Landsat-7 new spacecraft : SORCE - Solar Radiation and Climate Experiment Cool... :smile: Thanks Gironde... :clap: :clap: :clap:

Earth Observing-1 (EO-1) is a decommissioned NASA Earth observation satellite created to develop and validate a number of instrument and spacecraft bus breakthrough technologies. It was intended to enable the development of future Earth imaging observatories that will have a significant increase in ...

for the material editor menu to be active, you must first select an area to work with the mouse. after the settings become editable. note that for 'opacity' and 'shininess' after editing the zone, you must validate it in memory by changing the zone cursor. when I edit 'opacity' after I point my cur...

5th: open .cmod with cmodview and correct colors and other settings. Generally, I put the 'opacity' parameter at 1. but in my cmodview "material editor" inactive... it's not works... why? :think: but in my cmodview "material editor" inactive... it's not works... why? :think: thi...

the TDRS 2nd and 3rd generation satellite found these antennas. I put them slightly transparent to be true to reality. There remains the first generation where there is also a problem; here it is a forgotten surface vectorized in the original file. the body of the 1st generation was octagonal and t...
