Why a Specific Hierarchy of Categories

The Editorial Subcommittee of Marspedia examined the ad hoc approach of categorization of Marspedia articles and found it to be lacking a structure of how information about Mars is displayed and searched. The Subcommittee wanted a logical and navigable hierarchy of categories. This forms the core of a new Browse experience.

Creators of new pages should link one or more of the categories in the hierarchy shown below and no others to their page.
