It is shown that problem of Mercury flights, in terms of velocity requirements, are of same order as those involved in flights to Moon, Mars and Venus; major aspects of exploration of mercury include possibility of finding large quantities of frozen light elements (particularly carbon, oxygen, hydrogen and nitrogen) on dark side and possible value of tenuous atmosphere in decelerating spacecraft prior to landing; table includes total velocity change requirements for various astronautical objectives in inner solar system; 4 missions are considered for manned and unmanned vehicles.
