NASA warns of potential danger as retired satellite falls to Earth.

NASA has announced that a retired spacecraft, the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI), will re-enter Earth's atmosphere on Wednesday after nearly 21 years in orbit. The spacecraft monitored solar flares and powerful coronal mass ejections in low orbit above the Earth from its launch in 2002 until it was decommissioned in 2018. NASA experts noted that there is approximately a 1 in 2,467 chance that someone can be harmed by the debris as the 660-pound spacecraft burns up during its descent. Space debris has been accumulating around the Earth since the launch of satellite Sputnik 1 on Oct. 4, 1957, though most of it burns up upon re-entry and most pieces land in the ocean.
