It is the sixth mission in the Small Explorer program, selected in October 1997〔 and launched on 5 February 2002. Its primary mission is to explore the physics of particle acceleration and energy release in solar flares. HESSI was renamed to RHESSI on 29 March 2002 in honor of Reuven Ramaty, a pioneer in the area of high energy solar physics. RHESSI is the first space mission named after a NASA scientist. RHESSI was built by Spectrum Astro for Goddard Space Flight Center and is operated by the Space Sciences Laboratory in Berkeley, California. The principal investigator from 2002 to 2012 was Robert Lin, who was succeeded by Säm Krucker. ==Mission concept== RHESSI is designed to image solar flares in energetic photons from soft X-rays (~3 keV) to gamma rays (up to ~20 MeV) and to provide high resolution spectroscopy up to gamma-ray energies of ~20 MeV. Furthermore, it has the capability to perform spatially resolved spectroscopy with high spectral resolution. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Reuven Ramaty High Energy Solar Spectroscopic Imager」の詳細全文を読む スポンサード リンク
