This paper describes two new concepts in Mars Exploration, both of which involve the utilization of in-situ resources. In the first invention, we describe a Locally Refueled Planetary Explorer (LORPEX) which has practically unlimited range and life since it "lives off the land/atmosphere" by extracting fuel and oxidizer from the atmosphere, and possibly water at a later stage, as a source of hydrogen. The robot has been built and demonstrated to the media, including one science show in Pasadena. In the second invention, the concept is to obviate the difficulty of finding a suitable, lightweight substrate to bond the photovoltaic cells to; if we have an aerobot anyway for covering vast terrains, the balloon surface provides an ideal substrate for the PV cells at a minimal additional mass. Because of the truly large areas, and because sun-pointing is no longer a factor, the power availability is constant and represents at least a ten-fold increase over comparable/competing technologies; when this is combined with the minimum mass, the advantages should be apparent. Both of these technologies, LORPEX and PV-Enhanced Aerobots, won NASA NTR awards.
