- RHESSI (Reuven Ramaty High Energy Solar Spectroscopic Imager) is a NASA satellite that has been orbiting the Earth for over 20 years, providing valuable insights into the sun’s powerful bursts of energy known as solar flares. Launched in 2002 and decommissioned in 2018, RHESSI is now expected to make its final descent to Earth this week, bringing an end to its remarkable mission.
- RHESSI was launched by NASA in 2002 to study solar flares and their associated coronal mass ejections.
- The spacecraft weighs approximately 660 pounds, and it has been orbiting the Earth for almost 21 years.
- RHESSI was equipped with an imaging spectrometer, which served the main purpose of recording the sun’s X-rays and gamma rays.
- One of RHESSI’s significant achievements was capturing images of high-energy electrons that carry a large part of the energy released in solar flares, providing valuable data for scientists to understand these phenomena.
- RHESSI documented the huge range in solar flare size, from tiny nanoflares to massive superflares that were tens of thousands of times bigger and more explosive.
