Reuven Ramaty High Energy Solar Spectroscopic Imager (or RHESSI) is a NASA sixth Small Explorer , launched on 5 February 2002. It's primary mission is to explore the basic physics of particle acceleration and explosive energy release in solar flares. Reuven Ramaty is the eponym, and was a pioneer in the area - RHESSI was the first space mission named after a NASA scientist.
RHESSI was the first satellite to accurately measure terrestrial gamma-ray flashes that come from thunder storms , and RHESSI found that such flashes occur more often than thought and the gamma rays have a higher frequency on average than the average for cosmic sources.
