How do the Earth and planets respond? What are the affects on humanity? SET uses existing data and new data from the low-cost SET mission to achieve the following: Define the mechanisms for space environment effects; Reduce uncertainties in the environment and its effects on spacecraft and their payloads; Improve design and operations guidelines and test protocols so that spacecraft anomalies and failures due to environmental effects during operations are reduced."
