RHESSI (Reuven Ramaty High Energy Solar Spectroscopic Imager)

RHESSI (Reuven Ramaty High Energy Solar Spectroscopic Imager) was a satellite launched in 2002 to study the Sun’s intense solar flares. It focused on capturing high-energy X-rays and gamma rays emitted during these powerful eruptions. By analyzing this radiation, RHESSI helped scientists understand the processes that accelerate particles and release energy in solar flares. Its observations provided insights into the Sun’s magnetic activity and helped improve predictions of space weather effects on Earth, such as disruptions to satellites and power grids. RHESSI operated until 2018, significantly advancing our knowledge of solar high-energy phenomena.
