Researchers at the University of Manchester have developed an innovative modelling framework designed to mitigate the risk of satellite collisions and reduce space debris. This new tool bridges the gap between mission performance requirements and collision risk evaluations. Above all, it confronts a relationship that has historically been approached in silos with the different orbital realms.
The plan increases our dependence on Earth-observation satellites to an extraordinary degree. Their satellites are invaluable assets in the pursuit of the United Nations’ 17 Sustainable Development Goals (SDGs). This tool increases the efficiency of the planning and execution of diverse satellite missions. It plays a pivotal role in providing critical information about land use, smart urban development, ecosystems, and disaster response.
John Mackintosh, a PhD researcher at the University of Manchester, is the study’s lead author. He expresses how urgent this kind of research is to address the big challenges that satellite operations present us with. He explains that the tool is particularly relevant as Earth-observation satellites play a vital role in tackling environmental and social issues on our planet.
“Our study addresses this space sustainability paradox,” Mackintosh said. “It points to the danger that, though satellites can help address urgent environmental and social challenges on Earth, they may, in the long-term, imperil the sustainability of space itself.
The modeling framework provides a systematic evaluation of various aspects of mission performance. It figures out the best number of satellites required for various tasks as well as the proper altitudes they should function within. The tool is designed to quantify collision risks in multiple orbital environments. Its aim is to reduce the risks of hazards that lead to catastrophic collisions and contribute to increasing space debris.
This modelling framework is an especially timely addition to the conversation. The international community has become very concerned regarding the proliferating threat of space debris, and its impact on future satellite missions. The framework supercharges mission planning. It further bolsters the administration’s broader sustainability initiatives by ensuring that the use of satellites and their contributions to society help safeguard the value of space as a national asset.
