The Physics of Space Exploration
Move beyond the names of planets and learn the invisible forces that govern how we navigate the void and how stars live and die.
Like Duolingo, but for The Physics of Space Exploration. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Navigating the Gravity Web and The Life and Death of Matter. It assumes you already know the basics.

Key ideas in The Physics of Space Exploration
- Orbital stability requires balancing downward gravity with sideways momentum
- Without sufficient horizontal speed, gravity pulls the craft directly into the atmosphere
- Firing engines forward (prograde) raises the orbital height on the opposite side
- Pointing 'up' merely rotates the orbital ellipse rather than efficiently raising altitude
- The relationship between horizontal velocity and gravitational pull in maintaining an orbit
- Understanding that altitude changes are a result of velocity changes at specific points
- The Oberth Effect makes engines more efficient at higher speeds
- A craft travels fastest at its periapsis, the closest point to the planet
- The first burn creates an elliptical path called a transfer orbit
- The second burn circularizes the orbit at the new, higher altitude
- Identifying the most efficient point to perform a burn using the Oberth Effect
- The sequence of maneuvers in a Hohmann Transfer
- Aerobraking converts kinetic energy into heat through atmospheric friction
- Repeated shallow passes through the upper atmosphere save significant fuel
- The trade-offs and mechanics of using an atmosphere to slow down
- Gravity assist momentum theft
