Is there an update or add-on for Temple 1

[BattleShip Ron]

With the launch of NASA's Deep Impact mission on Jan. 12, I was hoping there might be a Temple 1 update.

Hi Ron,Jack Higgins has made an ssc file for the comet which you can find here
http://celestiamotherlode.net/creators/jackhiggins/tempel1.zip
It seems to have a normal orbit definition and an XYZ definition.Here is the normal version

Code: Select all

"Tempel 1" "Sol" # 9P/Tempel 1
{
   Class "comet"
   Mesh "asteroid.cms"
   Texture "asteroid.jpg"
   Radius 3.1

   EllipticalOrbit
   {
   Period          5.50495
   SemiMajorAxis  3.11766913943118
   Eccentricity      0.5187137226607602
   Inclination      10.54135925764414
   AscendingNode   68.96717429641359
   ArgOfPericenter 178.9188765308177
   MeanAnomaly      67.038757456382
   Epoch       2451920.5
   }

   RotationPeriod  10 # guess
   Albedo            0.1
}


I dont know if anyone has a model or XYZ file for the Deep Impact probe though,Jestr

Yep I have. It was also made by Jack Higgins.
Check out his website at;

Look for item 17.

I've slightly altered the .ssc file for the tempel comet to include the detailed .XYZ orbit and the normal orbit, so that the comet is not shown twice during the XYZ orbit definition.

It seems to be just the model of the impactor,not the orbiter,I checked on the Horizons site for details of the xyz but it only seemed to run until end of Jan,not sure about Jacks though,Jestr

[TERRIER]

Yes, it is just a model of the Impactor only. The xyz orbit runs from 30th December 2004 to 24th July 2005. (Deep Impact is due for launch on 12th January).
So it is not entirely accurate.
However the 'impact' occurs on July 4th, which seems to be OK.

Anyway, here's a screenshot of the 'lander' just before it hits Tempel 1 !!!
