What is the primary purpose of Space Domain Awareness (SDA)?

• A. Launch space missions
• B. Detect and track space objects
• C. Deorbit debris
• D. Control satellites

Answer: (B)

Space Domain Awareness is about building a complete picture of what exists in space and where it is. The main goal is to detect and track space objects—satellites, spent boosters, and debris—and keep orbital data up to date. This tracking lets operators predict close approaches, identify potential conjunctions, and assess collision risk, which supports safe and efficient planning for maneuvering or protecting assets. Activities like launching missions, deorbiting debris, or commanding satellites are separate functions: launching is about placing objects into orbit, deorbiting debris corresponds to removing or mitigating debris, and controlling satellites involves operating the spacecraft. SDA provides the situational awareness that makes all those activities possible and safer.
