Key Equations

1. Rocket Equation (Tsiolkovsky)

  • Δv = ve × ln(m₀/mf)
    • Δv: Change in velocity
    • ve: Exhaust velocity
    • m₀: Initial mass
    • mf: Final mass

2. Radiation Dosage

  • Dose = Flux × Exposure Time × Shielding Factor

3. Gravity on Mars

  • gₘ = G × Mₘ / Rₘ²
    • gₘ: Surface gravity of Mars (~3.71 m/s²)
    • G: Gravitational constant
    • Mₘ: Mass of Mars
    • Rₘ: Radius of Mars
