Chun(@satofishi):Prior to fram2, many people were concerned about polar radiation. However, it was actually the South Atlantic Anomaly that contributed a significant portion of our radiation dose. A spike is visible each time we flew along ~45°W longitude. By flying in a polar orbit, we actually spent less time crossing the SAA than we would have in a 51.6° ISS-like orbit.
