Cost Estimation and Development Approach of the EURASTROS Concept

The cost estimation from the European Astronautical Space Transportation (EURASTROS) study involved analogy, parametric and engineering build-up methodologies to identify the potential cost of a future European crew launch system to Low Earth Orbit. The total non-recurring program development cost of the EURASTROS concept are in the 4000 M€ range, whereas the average recurring mission cost would be in the 400 M€ range. The development approach considers four different test flights for certification. The results indicate comparability with other crew transportation programs/services, considering that reusability, which could further reduce mission cost in the future, was not part of the study
