TL;DR: RHESSI as discussed by the authors is a Principal Investigator (PI) mission, where the PI is responsible for all aspects of the mission except the launch vehicle, and is designed to investigate particle acceleration and energy release in solar flares, through imaging and spectroscopy of hard X-ray/gamma-ray continua emitted by energetic electrons, and of gamma-ray lines produced by energetic ions.
