Retired NASA Satellite Set to Reenter Atmosphere After Decades of Solar Study
- RHESSI monitored the sun for 16 years before shutting down in 2018 due to communication issues.
- The spacecraft is expected to reenter Earth's atmosphere on April 19, though the exact time and location are uncertain.
- Most of the 660-pound satellite will burn up, but some debris may survive reentry.
- The chance of harm to anyone on Earth is low at about 1 in 2,467.
- RHESSI provided valuable data about solar flares and coronal mass ejections in its time.
