Space Technology

How rockets, spacecraft, and the orbital economy actually work — physics to business case.

Space Technology / Overview
Entry point

Overview

Getting to space is easy to romanticize and hard to do. This hub explains the physics, the engineering, and the economics that decide what flies — no aerospace degree required.

This hub teaches you how space technology works, from the equation that shapes every rocket to the business models that decide which rockets get built. By the end you should be able to read industry news critically, follow a technical conversation, and — the real goal — make something of your own with what you’ve learned.

How to read this hub

The sections read in numbered order, and the order matters: each topic builds on the ones before it.

  1. The Map — the whole domain on one page. Start here.
  2. Core Mental Models — the eight ideas everything else hangs off.
  3. Core Vocabulary — the working terms of the field. Read it once, then return to it as a reference whenever a later page uses a word you’ve half-forgotten.
  4. Big Problems — where the hard, valuable problems live, and which topics equip you for each.
  5. Topics 05–12 — eight deep dives, ordered by prerequisite: how things move in space, how rockets push, how vehicles reach orbit and come back, what space does to hardware, how spacecraft are engineered, what satellites are for, and who pays for all of it.
  6. Be Creative — the capstone, where you produce something.
  7. Go Deeper — a short, curated reading list for when this hub isn’t enough.

The fast path: the site’s depth toggle has a Tourist mode that shows only each section’s summary paragraph. Flipping to Tourist and reading straight through takes about twenty minutes and gives you an honest aerial view of the whole domain. The full path — every section in Full mode — is roughly five hours of reading, plus 15–60 minutes per topic if you do the hands-on “Apply it” steps. Do them; they’re where the learning compounds.

You’ll build something at the end

Read with a destination in mind: the hub ends with Be Creative, where you produce one real artifact — a one-page mission proposal, a critical review of a real company or vehicle, or a working prototype like an orbit simulator. Each topic’s “Apply it” step generates raw material for that capstone, so by the time you arrive you’ll already be holding most of the pieces. Reading toward a production goal is dramatically stickier than reading to finish.
