Online Learning Platforms

Building Foundations from Anywhere

Not every student lives near an aviation high school, a Space Camp, or a museum with a flight simulator. But every student with an internet connection can learn the math, physics, and engineering fundamentals that every aerospace career requires — for free or nearly free.

The 5 platforms profiled here serve different needs. Khan Academy is the best free resource for building math and physics foundations from scratch — the prerequisite for everything else. MIT OpenCourseWare gives you the actual MIT aerospace engineering curriculum: lectures, problem sets, exams, solutions — completely free, no login required. Coursera and edX offer university-level aerospace courses from CU Boulder, MIT, TU Delft, and Georgia Tech — free to audit, with optional paid certificates. Brilliant teaches through interactive puzzles rather than lectures, building intuition in physics and math.

None of these replace hands-on experience. But a student who arrives at their first aerospace internship having completed MIT OCW's unified engineering sequence or Coursera's spacecraft dynamics specialization has a foundation that most college freshmen don't.

Building a Self-Study Path

If you're a K-12 student building aerospace foundations online, here's a progression that works:

Step 1: Math foundations (start here, regardless of career path)

  • Khan Academy — work through Algebra → Geometry → Trigonometry → Precalculus → Calculus. Use Khanmigo for help when you're stuck. This is the foundation for everything. No shortcuts.

Step 2: Physics (start alongside or after precalculus)

  • Khan Academy AP Physics 1 — forces, motion, energy, waves. The conceptual foundation for flight
  • Brilliant Classical Mechanics — if you prefer puzzles over lectures, this builds deep physical intuition

Step 3: Aerospace-specific courses (after calculus and physics)

  • For space enthusiasts: edX MIT 16.00x (Astronautics, taught by an astronaut) → Coursera Spacecraft Dynamics (CU Boulder)
  • For aircraft enthusiasts: Coursera Flight Mechanics (ISAE-SUPAERO) → MIT OCW Aerodynamics (16.100)
  • For engineering generalists: MIT OCW Unified Engineering (16.01-16.04) — the signature integrated sequence covering structures, fluids, thermo, and propulsion
  • For orbital mechanics: Brilliant Gravitational Physics → MIT OCW Astrodynamics (16.346)

Step 4: Advanced exploration (if you want to go deep)

  • MIT OCW Aircraft Systems Engineering (16.885J) — 23 video lectures on Space Shuttle engineering by the people who built it
  • Coursera Mars Mission Capstone (CU Boulder) — design a Mars mission using MATLAB
  • MIT OCW Autonomy & Decision Making (16.410) — AI for drones, autonomous aircraft, Mars rovers

The math is not optional. Every aerospace career — pilot, engineer, technician, operator — requires math. A pilot needs trigonometry and physics for navigation and performance calculations. An engineer needs calculus, differential equations, and linear algebra. A space operations specialist needs orbital mechanics. Start with Khan Academy. Get through calculus. Everything else becomes possible after that.
