The comprehensive, systematic process of mapping, scanning, and analyzing an entire celestial body (planet, moon, asteroid) to understand its geology, resources, atmosphere, and potential for life or habitation. It's the ultimate recon mission, combining orbital spectroscopy, surface rovers, seismic monitors, and atmospheric probes to build a complete scientific and strategic portrait. The goal isn't just a pretty picture; it's a data-rich inventory of every mountain, mineral deposit, water ice patch, and radiation flux.
Example: The Mars Reconnaissance Orbiter meticulously imaging the Red Planet's surface to chart ancient river deltas and ice deposits, while rovers like Curiosity drill into rocks for chemical analysis, together constitute a Planetary Survey. Before a crewed mission to the Moon's South Pole, a fleet of autonomous landers would conduct a detailed survey to pinpoint the exact location of water ice in permanently shadowed craters.
