Astrophysics and the Deep Cosmos
Like Duolingo, but for Astrophysics and the Deep Cosmos. 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.

Key ideas in Astrophysics and the Deep Cosmos
- VILM efficiency at aphelion
- Kinetic energy gain and velocity
- High altitude arrival vector changes
- Oberth Effect at periapsis
- Lever arm delta-v reduction
- Chemical vs electric Oberth benefit
- V-infinity leveraging maneuvers (VILMs)
- Maximizing the Oberth Effect
- C3 (characteristic energy) represents the square of the excess hyperbolic velocity
- Gravity assists can be used to decrease orbital energy (braking) by passing in front of the planet's orbital path
- The 'valley' of a porkchop plot represents the minimum energy transfer (Hohmann-like)
- Maximizing the Oberth Effect during a planetary departure
- Passing 'under' or 'over' a planet allows for significant orbital inclination changes without fuel expenditure
- Time-of-flight constraints create horizontal or diagonal cuts across the energy contours
- The 'bending angle' of the trajectory is determined by the flyby altitude and the planet's mass
- Applying V-infinity leveraging to minimize deep-space maneuver costs

Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Astrophysics and the Deep Cosmos the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
If you want to maximize the kinetic energy gain from your fuel, when should you ignite your engines?
