What is one of the responsibilities of the USSF regarding space domain awareness?

Characterizing and attributing potentially threatening behaviors is a key responsibility of the United States Space Force (USSF) in the realm of space domain awareness. This responsibility entails monitoring activities in space to identify and analyze behaviors of both state and non-state actors that could pose risks to U.S. and allied interests in space. By effectively characterizing these behaviors, the USSF can better assess threats and enhance national security measures in the space domain.

This aspect of space domain awareness is critical because the growing congestion in space, along with the increasing amount of objects in orbit, necessitates a robust understanding of the myriad activities taking place beyond Earth's atmosphere. The USSF's ability to attribute these behaviors to specific actors is essential for informing policy and operational decisions.

In contrast, the other choices, such as conducting military operations in space, developing international space treaties, and implementing space exploration missions, do not pertain specifically to the responsibility of space domain awareness but rather to broader aspects of military operations, diplomacy, or exploration initiatives.
