Comparative Research of Evaluation Models of Space Projects (Case study: NASA, European Space Agency and Russia)

To achieve the optimal model for assessment space projects in Iran, it seems necessary to study similar models in other reputable organizations. The purpose of this study is a comparative study of assessment models in Space Agency of European, NASA, and Russia. The assessment of space projects is done in the framework of internationally approved standards, by referring to the latest documents and related standards of these organizations, Content related to project assessment models have been collected to identify critical points in assessment a space project. Also, by evaluating the assessment models of these organizations and analyzing the relevant standards, the most important indicators in designing an assessment model have been determined. The results show that technical risk assessment, safety, scheduling, and budget are the most important assessment variables of a space agency assessment standard.
