What specific procedure is standard for maintaining data integrity when the DSN or an orbiter detects corrupted signal segments?

Answer

Requesting a retransmission of the corrupted segment

To combat the inherent noise and interference encountered over vast interplanetary distances, data transmission relies heavily on verification protocols. Digital data streams are outfitted with embedded error correction codes. If a receiving entity, whether it is an orbiter or a ground station belonging to the Deep Space Network, identifies anomalies or corruption within a received block of data, the standard procedure is not to discard the entire file but to specifically request that the transmitter resend only that particular corrupted segment. This selective re-sending of small blocks is vital for achieving high reliability and ensuring the scientific findings are transferred without corruption.
