These keywords were added by machine and not by the authors. ![]() Is there any hope, then, for a propulsion system that could take at least a few humans to habitable worlds orbiting nearby stars, on missions that begin late in the twenty-first century? Keywords ![]() This will be a time of vast change on Earth as our population peaks and nation states begin to give way to a true global civilization. ![]() Fission propulsion will probably be incapable of carrying humans to these beckoning new worlds fusion-pulse may remain politically and socially unacceptable, solar-sailing is too slow, and antimatter is too expensive. By the end of the twenty-first century we will have imaged Earth-like planets (if these worlds exist) orbiting nearby stars, and our probes will have reached the heliosphere at, at least, the inner fringes of the Oort Cloud. ![]()
