Three sensors, three bargains. Optical emits nothing, so nobody can ever tell they were looked at — but it needs sunlight or waste heat, and a cold coasting hull is very nearly invisible to it. Its resolution comes from a segmented primary that unfolds to twenty times the aperture you paid to launch. Radar reaches furthest and is the only thing that sees a dark, silent target, because it brings its own illumination — and that illumination is a shout every passive ear in range will log. It reads back one range line at a time, and its sharpness comes from the baseline your platform physically flies while the return stays coherent, so a fast crossing takes a good picture and a stationary stare takes none. Passive RF hears only what transmits: unbeatable against a beacon, deaf against silence.

Distances and orbits are true to scale at all times — planet positions come from JPL Keplerian elements, so what you see is where they actually are. Only body radii can be exaggerated, with [ and ]. Everything is a dot at 1× because that is genuinely what the solar system looks like. Surface imagery is real (NASA/USGS via Celestia and Planet Pixel Emporium) and streams in as you approach each body; procedural stand-ins are used until it arrives, and if you are offline.
