What is the main operational consequence of the substantial time delay inherent in Earth-Mars communication?

Answer

Rovers must operate with a high degree of autonomy, executing complex scripts and handling immediate hazards independently.

Because of the extreme round-trip time delay for signals—potentially over 44 minutes for a command and confirmation—it is physically impossible for operators on Earth to control a rover reactively, moment by moment. If an operator issued a simple command like 'drive forward one meter' and waited for telemetry confirmation before issuing the next instruction, the rover could have traveled much further, possibly into hazards, before the original instruction was confirmed. Therefore, the physics constraint forces the design of rovers to be highly autonomous, capable of executing pre-loaded complex operational scripts and making immediate, life-saving decisions, such as hazard avoidance, without direct, continuous human input.
