What the options mean
Physics model notes
- Gravity: g changes with altitude using μ/r², not a fixed 9.8 forever.
- Atmosphere: density falls exponentially, so drag fades as altitude climbs.
- Drag: D = ½ρv²CdA. This creates Max-Q, the scariest aerodynamic load.
- Mass: vehicle mass drains during burn; lower mass means the same thrust accelerates harder.
- Pitch program: the rocket starts vertical, then rotates toward horizontal velocity for orbit.
- Orbit readiness: compares final speed to circular orbital speed at that altitude. It is a teaching signal, not a full guidance optimizer.
