A NASA satellite that observed solar flares and helped scientists understand the sun’s powerful bursts of energy will fall to Earth this week, almost 21 years after it was launched. CNN reports: The retired Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) spacecraft, which launched in 2002 and was decommissioned in 2018, is expected to reenter Earth’s atmosphere Wednesday at approximately 9:30 p.m. ET, according to NASA. The spacecraft was equipped with an imaging spectrometer, which recorded the sun’s X-rays and gamma rays. From its former perch in low-Earth orbit, the satellite captured images of high-energy electrons that carry a large part of the energy released in solar flares, NASA said.<\/p>\n
Before RHESSI, no gamma-ray images or high-energy X-ray images had been taken of solar flares, and data from the spacecraft provided vital clues about the phenomena and their associated coronal mass ejections. […] NASA said that the agency, along with the Department of Defense, would monitor the satellite’s reentry into Earth’s atmosphere.<\/p>\n
