High resolution images of Mercury's surface, from the MESSENGER spacecraft, reveal many
bright deposits associated with irregular, shallow, rimless depressions whose origins were attributed
to volatile-related activity, but absent information on the nature and origin of that volatile matter.
I describe planetary formation, unlike the cited models, and show that primordial condensation from an
atmosphere of solar composition at pressures of one atmosphere or above will lead to iron condensing
as a liquid and dissolving copious amounts of hydrogen, which is subsequently released as Mercury's core
solidifies and escapes from the surface, yielding the observed pit-like features with associated
highly-reflecting matter. The exiting hydrogen chemically reduces some iron compound, probably iron
sulfide, to the metal, which accounts for the bright deposits.

An enormous amount of effort has been expended over the past sixty years in
attempts to understand the cause of the solar wind, with virtually no progress toward
developing an understanding of the precise processes involved in the acceleration process.
Here I show how the solar wind can be accounted for simply as a consequence of the
acceleration of thermal protons and ions by electrodynamic forces from an electric field which
pervades the heliosphere.
