Fundamental Limitations to Achieving Interstellar Flight,ments are for sending a robotic probe across the vastness of space. This analysis is necessary so that we may understand the challenge of interstellar flight and how it measures up technically compared to an interplanetary mission. Before a spacecraft can embark on such a journey however, it first must reach Low Earth Orbit.
