Should be used for questions related to preventing collisions in orbit. This includes risk assesment, evasive manuevors, avoidance althorithims, and other safety measures.
Collision avoidance is an attempt to prevent collisions, particularly in orbit. This includes changing course or deploying safety measures. Collision avoidance is a critical aspect of space exploration and is implemented by nearly all space agencies around the world to ensure safe and successful missions and to avoid the creation of more space junk.
