The Physics of Space Exploration

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.

For the part of you with thirty open tabs that never became anything.

What you'll learn

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
