🚀 Mission ATLAS — Lunar Rescue

Authentic Moon landing simulator · Classroom-ready · v4
Moon gravity: 1.62 m/s²
No atmosphere · No drag
Mass decreases as fuel burns

Academy Descent

Easy

Wide pad, generous fuel, steady approach. Best first run for reading lunar gravity correctly.

Pad Theta Rescue

Medium

Narrower landing zone, stronger sideways drift, tighter fuel. Rewards earlier horizontal control.

Eclipse Shift

Hard

Emergency profile with thin margins. Late braking fails fast, so build the descent corridor early.

Mission briefing

Prediction challenge

Controls: W/↑ throttle up · S/↓ down · A/← tilt left · D/→ right · P pause · R restart · H hint
Thrust dynamics: F_thrust = throttle × F_max a_y = F·cos(θ)/m − g_moon a_x = F·sin(θ)/m Fuel consumption: ṁ = F/(I_sp · g₀) Tsiolkovsky equation: Δv = I_sp·g₀·ln(m₀/m₁) Constants: g_moon = 1.62 m/s² I_sp = 300 s · F_max = 22 000 N
