Editing Orbiter

[[Image:Martins.jpg|right|thumb|Martin Schweiger, Ph.D., the developer of Orbiter]]
'''Orbiter''' (Orbiter Space Flight Simulator) is a freeware space flight simulator created by Martin Schweiger, Ph. D.,  of the Department of Medical Physics and Bioengineering at University College London. The most current stable version is Orbiter 2016.


==Structure==
Orbiter is a physics simulator which uses Newtonian physics to simulate the behaviour of spacecraft & other objects within our solar system. While somewhat vulnerable to crashes caused by add-ons or extreme simulation demands, Orbiter is generally quite stable when used properly. Orbiters file structure consists of [[Configuration File|configuration files]], [[Compiled HTML File|help files]], [[Mesh|meshes]], [[Texture|textures]] and [[Orbiter Module|modules]] which are integrated by the main executable ''Orbiter.exe''. This very flexible architecture makes addon development for Orbiter relatively easy. 


==System Requirements==
The standard ORBITER distribution requires the following minimum hardware features:
*  600 MHz PC or better (Pentium, Athlon, etc.)
*  256 MB RAM or more
*  Windows 9x/Me/2000/XP
*  DirectX 7.0 or higher
*  DirectX compatible 3D graphics accelerator card with at least 16MB of video RAM (32MB or more recommended) and DXT texture compression support
*  Approximately 100MB of free disk space for the minimum installation (additional high-resolution textures and add-ons will require more space).
*  DirectX compatible joystick (optional)
Installing high-resolution texture packs or add-ons may have an impact on performance and could require significantly higher computing specs.

==The default solar system==

The default solar system includes all known planets (except the [[Dwarf Planet|dwarf planets]]) and the major moons. Most planets are equipped with a [[Ephemeris|ephemeris]] module, which calculates the position of the celestial bodies to very high accuracy, making it possible to simulate historic space missions by using nearly the same manoeuvres as in reality.

Also included in the basic Orbiter distribution are several [[spaceport|spaceports]], where players can refuel their spacecraft:
* [[Kennedy Space Center]]
* [[Habana]] located close to Habana, [[Cuba]]
* [[Brighton Beach]] located on the [[Moons|Moon]] near side
* [[Olympus]] spaceport located on [[Mars]]

For a complete list of the bases included with the Orbiter distribution, see the [[Surface bases]] article.

==Standard Spacecraft==

* [[Dragonfly]]
* [[Luna OB-1 Station|Luna Wheel Station]]
* [[Delta-glider]]
* [[Shuttle-A]]
* [[Space Shuttle Atlantis]]
* [[Shuttle PB]]
* [[Hubble Space Telescope]]
* [[Long Duration Exposition Facility]]
* [[Carina Satellite|Carina]]
* [[International Space Station]]
* [[Mir]]

In spite of its destruction in reality, Mir is placed in an alternative orbit making it a possible start for interplanetary missions.

==Installation Instructions==
The Orbiter install with two methods: The MSI and the ZIP method.
The MSI (Microsoft installer) method installs Orbiter like a normal Windows application. Just run the MSI file to start the interactive installation process. This method will automatically create a desktop shortcut and start menu entry, including an uninstall option. This method is easy to use, but a bit more restrictive.
Manual ZIP file extraction is the traditional method for Orbiter installation. Download the ZIP file, create an Orbiter folder, and extract the contents of the ZIP file into the folder. That's all, and you are ready to launch orbiter.exe. This method is non-intrusive (it doesn't change the registry or system resources), allows multiple copies of Orbiter on a single system, and can be uninstalled by simply deleting the Orbiter folder.
===Optional Texture Packs===
Optional texture packs provide high-resolution surface textures for planets and moons included within Orbiter distribution. This will improve the visual appearance in many situations, but requires more computing power and a lot of hard disk space.

==Open Source==
It was announced by Dr. Schweiger on 27 July 2021 that Orbiter has been published under an open source license, ([[w:MIT license|Wikipedia: MIT license]]). Details can be found at the Orbiter forum [https://www.orbiter-forum.com/threads/orbiter-is-now-open-source.40023/ , this thread].

-==Versions==
-Not long after Martin made Orbiter open source, he uploaded all the versions he still had to the [https://www.orbiter-forum.com/resources/ Resources] section of [https://www.orbiter-forum.com/ Orbiter-forum].

-===Orbiter 2002-P1, with subsequent patches===
-Author's Comments:<br>
-Orbiter's second release in 2002, which then included three subsequent revisions as patches to the base 021202 install.
-These are cumulative, which means if you want 030303 you need to unpack the 021202 base, then the 021206 patch, the 021217 patch, and then finally the 030303 patch, to get a working install.
-You'll need both _base and _tex for a working 021202 base install.

-===Orbiter 2003-P1===
-Author's Comments:<br>
-The first revision of Orbiter from 2003. Not originally called 2003-P1 (as far as I know) but adjusted to fit the more recent format.
-You need _base and _tex for a working Orbiter install. _sdk is optional, for developing addons against.

-Author's Comments:<br>
-The second revision of Orbiter from 2003. While this wasn't called 2003-P1 at the time as far as I can tell, that's what Orbiter later started using, so I've kept that format here as we go backwards in time.
-You need _base and _tex for a working Orbiter install. The _sdk is optional.

-===Orbiter 2005===
-Author's Comments:<br>
-Orbiter 2005 - both the initial release and the later patch for a revision.
-The 050216 patch needs to be applied over the base 050116 install, it won't make a standalone Orbiter install by itself.
