To this end, eSpace has a number of projects that will help realise this vision of a safe and sustainable space environment. On the educational side, eSpace hosts the Space Situational Awareness (SSA) student team, which works at tracking space debris to create a catalog that will be used to send alerts to space operators when their assets are at risk of collision with a trackable debris. A research project focused on implementing life cycle assessment (LCA) in the early design phase of future space transportation vehicles is also currently in development.
eSpace is the main contractor leading the development of the Green Space Logistics - Assessment and Comparison software (ACT) that will support ESA Future Launch Preparatory Program to perform life cycle assessments of space transportation vehicles. The tool aims at highlighting environmental hotspots and recommending actions for eco-design and reduced environmental impacts of future launchers. The software will also be used as an environmental module (assessment of impacts, eco-design options trade-off, space debris risk mitigations, etc.) in the eSpace concurrent design facility (CDF).
With the DAWN project on space logistics optimisation, eSpace is working on future space logistics use cases, in particular an Active Debris Removal (ADR) mission as a service and constellation deployment scenario. The Technology Combination Analysis Tool (TCAT) uses current and future space transportation vehicle design and performances to optimize the mission profile of a use case. The cost of a mission is traded off with its duration using different models of propellant consumption based on the user inputs. The eSpace vision is to combine those tools (ACT and TCAT) with other existing ones to offer an open-source, comprehensive end-to-end space logistics assessment software.
The Space Sustainability Rating (SSR), hosted by eSpace, is an initiative to foster voluntary action from space actors to safeguard the long-term sustainability of the space environment. Initiated by the World Economic Forum in 2016, the SSR relies on a robust methodology developed by experts from the European Space Agency (ESA), the Space Enabled Research Group at the Massachusetts Institute of Technology (MIT), the European Space Agency (ESA), the University of Texas at Austin, and BryceTech to enable space operators to assess the level of sustainability of their space missions and operations. The SSR is also developing new modules to increase the rating system scope and consider the challenges and trends for the space environment: dark and quiet skies (impacts on astronomical observations), life cycle assessment, and potentially developing a Launch Vehicle Sustainability Rating (LVSR).
