What broader scientific importance does understanding Mercury's volatile retention hold for inner solar system formation studies?

Answer

It provides critical constraints on the initial chemical complexity or the efficiency of accretion mechanisms near the Sun.

The puzzle presented by Mercury's volatile inventory—the closest planet retaining materials that should have boiled away—is fundamental to understanding the birth of all inner solar system bodies. If Mercury, under the most extreme thermal conditions, retains these elements, it forces a revision of initial conditions. This means the solar nebula was likely either more chemically zoned or complex than previously assumed, or that the physical processes governing accretion (like speed and shielding mechanisms) were far more effective at preserving volatile material close to the Sun than current simple high-temperature evaporation models account for.
