READING THE PORKCHOP

Each cell asks: "if I launch on date X and arrive on date X+TOF, how much fuel does it take?" Lower numbers = cheaper missions.

X · departure date: When you launch from Earth.
Y · time of flight: How long the trip takes (in days).
Color · launch ∆v: Cool teal = cheap (~3 km/s). Yellow = moderate. Red = very expensive (>9 km/s).
How to use it: Click a cool-colored region near the natural Hohmann minimum (~250-day TOF, every ~26 months) — that's the cheapest launch window. The right panel shows the exact dates and ∆v.
