A working hypothesis of Mercury's history is presented.

The oldest terrains on Mercury seem to be better preserved from modification by ejecta from subsequently formed impact basins because of higher surface gravity. The large lunarlike impact craters on Mercury can be interpreted as part of a distinct episode of bombardment which may… CONTINUE READING
