context

Space transportation technologies are intrinsically complex, some needing long development cycles of up to a decade. For this reason, ESA sought early insights into long-term trends and potential evolutions in all application domains taking into account the needs of future programmes currently under preparation.

main objectives

NESTS was a 4-month ESA FLPP study with the goal of investigating defined preliminary elements for future space transportation solutions to be used in 2030β€”2050. In this project, eSpace’s goal was to contribute value to the NESTS project and ESA’s efforts to plan future European space transportation; to strengthen collaboration with ArianeGroup; to gain capability in practical future planning criteria and trade-offs. eSpace’s role in this fast-paced project was to establish the method and criteria that would be used to assess the different space transportation services and system concepts, including criteria and weighting factors; to contribute to the elaboration of high-level specifications related to on-orbit servicing, constellation deployment, and Moon missions; and to manage the trade-offs to be performed on space transportation services, including through online workshops.
