NASA's 600-pound dead satellite to crash back to Earth with low risk of danger.

NASA reported that the retired Reuven Ramaty High Energy Solar Spectroscopic Imager spacecraft, also known as RHESSI, will reenter Earth’s atmosphere on Wednesday after over two decades in orbit. While most of the 660-pound satellite is expected to burn up during its descent, some parts have a chance of surviving the fiery return. The risk of harm to anyone on Earth is low, approximately 1 in 2,467. RHESSI has observed solar flares and coronal mass ejections that have aided scientists’ investigation into the physics of the sun’s energy bursts.
