Long Duration Manned Space Flight: Yesterday's Limitations-Today's Challenges-Tomorrow's Realities

摘要

This paper identifies some of the potentially limiting factors in long duration manned flight. In no way can this be construed as all inclusive list of the problems that we face; nor should one infer that summaries of the basic problems are comprehensive in scope. Rather, by familiarizing the reader with these issues, with these issues, hoped that he or she will have a better understand the challenges of the manned space program and a better appreciation for the work facing such a momentous human undertaking. Furthermore, it is important for the reader to understand how vital it is for the U.S. to return to space, and how important it is to design, build, launch, and permanently occupy the U.S. Space Station. This capability and resource represent the first opportunity to conduct the work that must be completed before mankind can truly colonize space.
