A new report from NASA’s Office of Technology, Policy, and Strategy provides agency leadership with new insight about how to measure the risks presented by orbital debris. “This study allows us to start to answer the question: What are the most cost-effective actions we can take to address the growing problem of orbital debris?” said NASA analyst Jericho Locke, the lead author of the report. “By measuring everything in dollars, we can directly compare shielding spacecraft to tracking smaller debris or removing 50 large pieces of debris to removing 50,000 smaller ones.
In total, the study compares the cost-effectiveness of more than 10 different actions that can be taken to reduce the risk from orbital debris, such as shielding, tracking small debris, or remediating large debris. Eventually, the team hopes to assess the cost-effectiveness of combinations of different actions, known as portfolios.
