I built the foundation of a NASA style mission simulator in Pygame.

The focus was keeping everything simple but physically believable enough to feel like a real launch system.

What i added :
A controllable rocket object with basic physics
Gravity pulling the rocket down constantly
Thrust system controlled by toggling the engine (SPACE BAR)
Fuel consumption that decreases while the engine is active
Altitude and velocity tracking in real time
A basic HUD showing mission telemetry (altitude, speed, fuel, engine state)
Simple visual representation of a rocket with a flame animation
Ground reference to give a sense of scale

Result:

You can now launch a rocket from the ground, control its thrust, and watch it respond to gravity and fuel constraints while tracking live telemetry like a simplified NASA test console.
