🚀 FUNDAMENTAL PRINCIPLES
The Physics That Defies Gravity
Modern rocketry still rests on these immutable physical laws, now enhanced with computational precision:
- Newton's Third Law - Action/reaction remains the core principle, but with exhaust velocities now exceeding 4.5 km/s
- Tsiolkovsky's Insight - The rocket equation now informs AI-optimized staging and fuel management
- Oberth Effect - Modern trajectories maximize this velocity-dependent efficiency boost
The 2025 Rocket Equation
Where new factors include:
- Δvadd - Additional velocity from techniques like aerobraking and gravity assists
- Isp values now ranging from 250s (chemical) to 5000s (electric)
- Mass ratios benefiting from advanced materials and construction
