The Orion's Arm Universe in Celestia

Celestia OA

To explore the universe of Orion's Arm first download the 3D Astronomy program Celestia. The best results will be obtained by using the newest version, Celestia 6 currently in beta testing, available here:

Celestia-1.6.0.exe/download Once you have downloaded the program take some time to become familiar with the controls (this page from NASA shows the main functions very clearly).

To load the Orion's Arm addons you can download at least the first three of the OA Addons zip files shown below into the folder 'extras' inside Celestia
  • OA Addons zip 1 - this small file contains the locations information for the Orions Arm systems
  • OA Addons zip 2 - this large file (142 megs) contains the textures for the planets described in file 1. This may take some time to download.
  • OA Addons zip 3 - this medium-to-large file (34 megs) contains some of the Orion's arm spacecraft and habitats.
Unzipping these three files into the 'Extras' folder will create a subfolder called 'oaaddons'; this folder will contain several subfolders, and will be the home for all the Orion's arm material. More addons are available on this page: (Orion's Arm Addons Page 2)


Clickable Location Links

Once you have loaded these three files, you can explore the first of the Orion's Arm systems. The easiest way to do this is to click on a preset Cel:URL link, which will take you to a preset destination within Celestia. Cel:URL links are shown below in red; note they will not work properly until you have downloaded both Celestia and the appropriate addons.

Tip: you can have several different versions of Celestia on your system if you like, each with different sets of addons. If you have more than one version of Celestia these links may open the wrong version. So to ensure the links work correctly open the correct version of Celestia first. If you have only one version of Celestia. opening it first will help speed it up in any case.
