In space operations, what is a conjunction?

• A. A close approach between two objects requiring avoidance maneuvers.
• B. A type of orbit perturbation caused by atmospheric drag.
• C. A communication protocol for secure channels.
• D. A method of determining onboard power resources.

Answer: (A)

Conjunction in space operations refers to a close approach between two objects that could lead to a collision and may require an avoidance maneuver. Tracking of satellites and debris identifies when trajectories bring objects within a defined proximity, and a conjunction assessment evaluates collision probability and potential miss distance. If the risk is significant, operators plan and execute a collision avoidance maneuver to ensure safe separation. This is not about orbital drag effects, a communication protocol, or determining onboard power resources.
