Parts of giant Nasa satellite to crash to Earth, posing low risk
"According to the US military's Space Force, the roughly 1,323lb (600kg) spacecraft, one of twin probes launched in 2012 to investigate the Van Allen radiation belt, is estimated to re-enter Earth's atmosphere at about 7.45pm EDT. Most of the craft, it said in a prediction published Monday, will burn up on re-entry, yet some components are expected to survive."
"Debris falling from space is not uncommon, and Wired reported in 2009 that over a 40-year period roughly 5,400 tons are thought to have survived re-entry. But the odds of being hit are low because about 71% of Earth's surface is covered by water."
"The odds that you will be hit are one in several trillion, so quite low for any particular person, Mark Matney, a scientist in the orbital debris program office at Nasa's Johnson space center, Houston, told the outlet."
A 600kg NASA spacecraft from a 2012 Van Allen radiation belt mission is predicted to re-enter Earth's atmosphere on Tuesday at approximately 7:45pm EDT. While most of the craft will burn up during re-entry, some components are expected to survive. The Space Force estimates a 1 in 4,200 probability that someone on Earth could be harmed. Debris from space re-entries is common, with approximately 5,400 tons surviving re-entry over 40 years. However, the actual risk to individuals remains extremely low due to Earth's 71% water coverage and vast population distribution. Only one documented case exists of a person being struck by space debris: Lottie Williams in 1997.
