The solid core nuclear thermal rocket (NTR) represents the most promising propulsion technology available for manned interplanetary travel to Mars. This technology can also be applied to an unmanned vehicle in the form of a cargo vehicle used in conjunction with a piloted crew vehicle destined for Mars. The objective of this study is to analyze a NTR cargo vehicle by performing a parametric analysis of selected vehicle components such as NTR engine type and thrust level, payload category, fuel tank material and configuration and the number of NTR engines. The study was conducted using launch opportunities selected from the 2010-2011 time frame. Two NTR concepts were examined - the Nuclear Engine for Rocket Vehicle Application (NERVA) and the NERVA Derivative (NDR). This paper summarizes the results of the study with discussion of the optimal parametric values, ranges, and configurations.
