Welcome to the General Space Wiki!

This Wiki is to provide a location for general space articles and content for the same project that brought you Lunarpedia, Marspedia and Exodictionary. Construction is underway and you can help!

New Users Start Here!

  • Click here to create your account -- or else donate your content anonymously.
  • You can click on your user name and create a page to tell us about yourself.
  • If you have questions or comments about any page then click on the "discussion" tab and type in the edit box. Make sure to sign the text with a row of four tilda (~) characters

How to layout your pages

Both these files are best saved to your hard drive and also printed. Right click and "Save Link As" to do that. Or, if you have the plugins installed you can just click and view in your browser. But please don't forget to come back here afterwards :-)

Signing your comments

When you add comments to User_talk pages, please sign using <br>-- ~~~~, this automatically adds your signature and a time and date stamp in UTC like so:
-- MikeD 15:47, 30 April 2007 (UTC)

Anonymous users (those not logged in) should also sign with some sort of ID, like for instance <br>-- JoeBloggs ~~~~~ which would result in something like the following:

NASA Images: NASA still images, audio files and video generally are not copyrighted. You may use NASA imagery, video and audio material for educational or informational purposes, including photo collections, textbooks, public exhibits and Internet Web pages. This general permission extends to personal Web pages.
This general permission does not extend to use of the NASA insignia logo (the blue "meatball" insignia), the retired NASA logotype (the red "worm" logo) and the NASA seal. These images may not be used by persons who are not NASA employees or on products (including Web pages) that are not NASA sponsored.

Original Work is Allowed

We are more open to material types than Wikipedia, and less interested in deleting material. Specifically, Wikipedia enforces a rule that all entries must NOT be "original work". That rule does not apply for Lunarpedia, we are very happy for you to post original work, provided it is not copyright. Therefore there is not so much duplication between Lunarpedia and Wikipedia as you might expect. For example, the Lunarpedia page on Solar Power Satelliteslunarp contains interesting material which under Wikipedia rules would be deleted because it is "original work".

Note: Once "original work" has been published on Lunarpedia, then anybody could put on Wikipedia a link to the Lunarpedia article, and that might be OK for Wikipedia as it would no longer be original work, and references are usually accepted over there. For those cases where you want to reference it elsewhere, we could arrange for it to become read-only protected.

No Need to be Notable

Wikipedia enforces a requirement that all articles about people or organizations must demonstrate why the subject is "notable". There is no such requirement on Lunarpedia, although there is a general expectation that it should somehow be related to Lunar Development.

No Need to be Neutral

You can advocate positions, but expect to be challenged. Conversely, do not just delete material you do not agree with, but feel free to add a rebuttal.

If you do advocate positions, please do so in a manner that makes it obvious that it is your personal position and not that of Spacepedia as a whole. You can do this using the tags '''''{{PersPosArticle}} ~~~''''' or '''''{{PersPosSection}} ~~~''''' which would display something like so:

This article reflects the personal position of MikeD
This section reflects the personal position of MikeD

Commercial Links are OK

It is perfectly fine to highlight products or services, including both your own and those of other persons or companies. Just make sure it is relevant.

Software Capabilities

Lunarpedia uses Mediawiki, so in many respects it is very similar to Wikipedia.


Interwiki is supported between Spacepedia and it's sister sites ExoDictionary, Lunarpedia and Marspedia.
To use interwiki you just use tags like
[[exd:Sandbox]], [[lunarp:Sandbox]] and [[marsp:Sandbox]]. These would take you to
exd:Sandbox, lunarp:Sandbox and marsp:Sandbox respectively.

Other examples would be: [[exd:Azimuth]], [[lunarp:Carbon economy]] and [[marsp:Mars Express]]. These would take you to
exd:Azimuth, lunarp:Carbon economy and marsp:Mars Express respectively.

The interwiki prefixes on the other sites are identical.
