Wikipedia:WikiProject Spaceflight/SpaceX/First principle

This page is part of the SpaceX task force's online guidebook and contains instructions, recommendations, or suggestions for editors working on SpaceX or spaceflight-related articles. Many pages of the guidebook are borrowed and adapted from the WikiProject Military history's Academy.

Build your article from reliable sources, not from your knowledge. As the first principle article on Wikipedia said:

A first principle is a basic proposition or assumption that cannot be deduced from any other proposition or assumption. [...] In physics and other sciences, theoretical work is said to be from first principles, or ab initio, if it starts directly at the level of established science and does not make assumptions such as empirical model and parameter fitting.

To counter that is original research, which is strictly prohibited. This is because all information must be attributable to a reliable, published source. Information reliability cannot be trusted by strangers in the Internet, which this has been a recurring problem in spaceflight articles. Therefore, even if you know what the rings in SpaceX Starbase are doing, or unannounced satellites that are going to launch on future Falcon 9s, you must not add them to articles without proper reliable sources to keep their integrity.
