dc.description.abstract
It can be assumed that the composition of Mercury’s thin gas envelope (exosphere) is related to the
composition of the planets crustal materials. If this relationship is true, then inferences regarding the bulk
chemistry of the planet might be made from a thorough exospheric study. The most vexing of all
unsolved problems is the uncertainty in the source of each component. Historically, it has been believed
that H and He come primarily from the solar wind, while Na and K originate from volatilized materials
partitioned between Mercury’s crust and meteoritic impactors. The processes that eject atoms and
molecules into the exosphere of Mercury are generally considered to be thermal vaporization, photonstimulated
desorption (PSD), impact vaporization, and ion sputtering. Each of these processes has its own
temporal and spatial dependence. The exosphere is strongly influenced by Mercury’s highly elliptical
orbit and rapid orbital speed. As a consequence the surface undergoes large fluctuations in temperature
and experiences differences of insolation with longitude. We will discuss these processes but focus more
on the expected surface composition and solar wind particle sputtering which releases material like Ca
and other elements from the surface minerals and discuss the relevance of composition modelling
