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: Interest in studying the possibility of extraterrestrial life has led to the re-emergence of the Red Planet as a major target of planetary exploration. Currently proposed missions in the post-2000 period are routinely calling for rendezvous with ascent...
