It is part of the LWS program of Science Missions and Targeted Research and Technology (TR&T) ground-based investigations that respond to the following questions: How and why does the Sun vary? How do the Earth and planets respond? What are the effects 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."},{"1":"The SET-1 payload is flown on the Air Force Research Laboratory (AFRL) Demonstration and Science Experiments (DSX) spacecraft.
