Space Domain Awareness sensors are used to do what?

• A. To detect and track space objects and monitor the environment.
• B. To measure Earth's magnetic field.
• C. To control air traffic.
• D. To provide consumer GPS data.

Answer: (A)

Space Domain Awareness focuses on sensing the space environment to know what objects are in orbit and what conditions affect them. Space Domain Awareness sensors are designed to detect and track space objects—like satellites and debris—and monitor the surrounding space conditions to assess threats, plan conjunction analyses, and support safe, reliable operations in space. This capability underpins space traffic management and collision avoidance, as well as understanding how space weather and atmospheric drag influence object trajectories. The other options describe activities outside this scope: measuring Earth's magnetic field is magnetometry, not SDA; controlling air traffic belongs to the aviation domain; and providing consumer GPS data is about navigation services, not space-domain sensing.
