Abstract: Human lunar colonization has been studied at length, with the broad conclusion that it is technically feasible, but costs far too much. Even assuming a factor of 50 launch cost reduction, traditional models suggest that a lunar colony supporting 1,000 people...
Abstract: Major cost reductions in planetary missions, especially those with high launch energy requirements, are made possible by a modified launch mode in which part of the total launch energy is generated by onboard propulsion rather than by the launch vehicle....
Abstract: Primary mission objectives for most deepspace missions to date have emphasized acquiring scientific data and expanding our understanding of the solar system; some contemporary missions target advanced technology demonstration with science as a secondary...
Abstract: A simulation environment is developed that will propagate a controlled orbit about asteroid and cometary bodies in the solar system. This simulation allows as input the location and orbit of the central body, and includes models for the gravitational field,...
Abstract: Creating and maintaining the long term structure of a constellation can be a major element of cost and risk. Both can be substantially reduced by the use of straightforward, low-cost autonomous orbit maintenance. In most cases, this can be done with...
