Are we asking the right questions about space debris?
... a limited subset of the debris population that will create the most consequential events (i.e., clusters of massive abandoned space objects) provides clarity in risk calculations that may help to prove or disprove this hypothesis. The four clusters...

Urgent action needed to keep satellites safe in orbit
... must also continue to detect, track and characterise resident space objects just like rocks and shoals in shipping lanes, as ...is fundamental. Unlike rocks and shoals, however, the space objects are in constant motion and must be frequently monitored....

Measuring space debris risk
The starting point for tracking space objects is the US Joint Space Operations Center (JSpOC) catalogue of all artificial Earth orbiting objects. The tracked objects’ orbits are published in the form of Two Line Element sets or TLEs. This is a great...

AI offers new approach to space situational awareness
... to fuse data sources and it is clear that these methods can be well suited to SSA challenges. An example of this is space object characterisation. Data from different sources, electronic optics, radar and radio frequency (RF), can all be fused for...

Academia’s role in space protection, space traffic management & orbital debris mitigation
... - let alone a holistic, cohesive cause-effect paradigm for understanding and predicting the space environment’s effects and impacts on space objects and events. Further, we task individual sensors to collect data instead of tasking a sensor network...
