🌕 Moon Landing Simulator

Pilot an Apollo-style lunar module to a soft landing. Lunar gravity is 1.62 m/s², the engine uses Isp = 311 s (Apollo DPS), and fuel is consumed by dm/dt = −T/(Isp·g₀). Touch-down target: |v_y| < 3 m/s, |v_x| < 2 m/s.

Apollo Descent Module Physics

The lander's equations of motion are: a_x = T·sin(θ)/m and a_y = T·cos(θ)/m − g_moon, where T is thrust, θ is tilt angle and m is current mass. Fuel consumption follows the Tsiolkovsky mass-flow equation: dm/dt = −T/(I_sp·g₀). The Apollo DPS (Descent Propulsion System) had a specific impulse of roughly 311 s and could throttle between 10% and 92.5% of its 16 kN rated thrust.
