A new metric called the CRASH Clock quantifies the risk of catastrophic satellite collisions, revealing that a severe event like a solar storm could cause a collision in less than three days, highlighting the urgent need to address space debris and satellite congestion, especially with the rapid increase in satellite constellations by companies like SpaceX.
A new NASA report suggests that dealing with space debris could be more cost-effective than previously thought. The report evaluates over 10 strategies for mitigating, tracking, and removing orbital debris, comparing their cost-effectiveness. It aims to find the most economical ways to protect satellites and the space environment, considering both direct damage and the costs of avoiding debris. The study is part of NASA's broader effort to improve space sustainability by applying an economic perspective to the issue.
