The history of early Martian aircraft developments is reviewed and recent studies are evaluated resulting in several proposed Delta II launched concepts. Mars's atmospheric and global surface investigations can benefit greatly from the aerial mobility of flying platforms. Advances in autonomous guidance and navigation create new missions by enabling these concepts to accurately target specific terrain features. Three concepts were developed and are evaluated in this report: an improved mid-weight version of the early large-span JPL/DSI flyer (1978), a "minimum mission" winged concept and a parasail-equipped lander delivery system. The parasail flyer achieves accurate, terminal targeting for its payload reducing the risks associated with landing site selection for roving explorers. In addition to concept design and feature descriptions a systems engineering, risk reduction approach is developed which delineates the necessary technology program to achieve performance goals and mission success.
