Edinburgh, April 21, 2022. – The Space Sustainability Rating (SSR), hosted by the eSpace-EPFL Space Center, will allow space operators to improve the sustainability of their mission by earning a rating after transparent data-based assessments and practical advice that supports efforts space debris mitigation. The program, under which spacecraft and satellite operators will be scored based on space debris mitigation measures, will go live in June 2022.

The SSR is a voluntary rating and certification system accessible to all space actors who wish to join. It assesses the level of mission sustainability by focusing on six aspects including collision avoidance process and data sharing.

Detectability, Mission Index (the level of harmful physical interference), assessment of compliance with international standards and regulations are also part of the criteria. The final aspect to assess is the range of actions needed to increase the likelihood of success of external services. After completing the scoring, the SSR will offer tailored and actionable practical advice to improve the level of mission sustainability.

SSR has been developed over the past three years by the World Economic Forum, ESA, Massachusetts Institute of Technology, BryceTech, and the University of Texas at Austin, among others. Leading space players including Stellar, Nihon University in Japan and the Secure World Foundation have already joined the initiative.
