What is the role of space-based sensors in Space Domain Awareness?

• A. To monitor and characterize space objects and the operational environment.
• B. To harvest solar energy.
• C. To track weather on Earth.
• D. To coordinate air traffic.

Answer: (A)

Space Domain Awareness hinges on knowing what is in space and how the space environment behaves. Space-based sensors provide a vantage point to observe the region around Earth that ground sensors can’t always see, enabling ongoing detection, tracking, and characterization of objects and debris in orbit. They help determine orbits, sizes, shapes, and possible maneuvers, and they monitor the surrounding space environment—space weather and other conditions—that can affect sensor performance and mission operations. This persistent, global perspective is essential for identifying unknown objects, assessing collision risks, and informing decisions for space operations. Harvesting solar energy, tracking weather on Earth, and coordinating air traffic lie outside the primary role of space-based sensors in Space Domain Awareness.
