About this site

Zero2Expert is a reading site for learning the technology and history of Tesla and SpaceX from zero. No special knowledge is needed: read in order and the whole picture comes together.

How to read

The "Learning route" on the home page is a map of the reading order. We recommend starting with Part 0 (Musk's journey).

Our rules

• Numbers and dates come with sources. What we could not confirm is written as unconfirmed.
• Claims that rest on press reports or personal accounts are written as such ("reportedly"), apart from facts.
• We do not write about stock prices, wealth or other investment topics.
• Some figures are AI-generated illustrations, and are labeled as such.
