The Reuven Ramaty High-Energy Solar Spectroscopic Imager (RHESSI) - Mission Description and Early Results , Kluwer Academic Publishers (now Springer), 2003, was published early in the mission to rapidly disseminate information about the mission, its data, and results. It includes technical instrument and system desciptions and early-science results. The chapters in the book were also published as journal articles in Solar Physics, Volume 210, Numbers 1-2, November 2002.
