For long-term studies, numerical simulations are at the center of predicting the space debris environment of the upcoming decades. In the scope of the study, the authors present the architecture and proof-of-concept results for a numerical simulation capable of modeling the long-term debris evolution over decades with a deterministic conjunction tracking model in contrast to typically employed Monte Carlo methods. For the simulation, an efficient propagator in modern C++ accounting for Earth’s gravitational anomalies, solar radiation pressure, and atmospheric drag was developed.

The BIOINSPACED project was initiated to find bio-inspired solutions for space debris removal because the identification, orbital alignment, capture and removal of uncooperative bodies in space is incredibly complex and no fully functioning method is available to date. Biology and its evolved mechanisms often provide specialized concepts that show great transferability to technical systems.

Nowadays, human Moon exploration, and the consequent desire to establish a permanent settlement on its surface, represents one of the most fascinating challenge to face. The permanent presence of a human outpost very far from Earth raises the problem of the huge amount of payload required for the settlement, as well as the need of rapid and in-time supply of material and spare parts useful for all the activities carried out in-situ, including the realization of medicals tools and patient-specific back-up implants.

ESA has traditionally specified space systems using a document-based approach, and is now in a transition process towards the digitalisation of systems engineering activities. At the same time, space industry companies have their own internal set of best practices and experience with Model-Based Systems Engineering (MBSE).

To solve this problem, ESA initiated this study led by CGI in partnership with OHB to identify a way to harmonise the different MBSE approaches from industry and compile the information into a concise book.
