A NASA satellite is expected to fall to Earth this weekend after nearly 40 years in space. The Earth Radiation Budget Satellite (ERBS) was launched in 1984 aboard the space shuttle Challenger.
It was originally sent into space with a lifespan of just two years to study how Earth absorbed and radiated energy from the sun. But the satellite continued to make ozone and other atmospheric measurements until its retirement in 2005.
Now the 2,450 kg object is set to crash back to Earth. Most of the satellite will burn up after re-entry, according to NASA, but some parts are expected to survive.
NASA said the chance of debris falling on anyone is "very low" - putting the odds of anyone on Earth being injured by falling debris at about one in 9,400.
According to the US Department of Defense, the satellite is expected to land on Sunday evening, give or take 17 hours.
The satellite is expected to pass over Africa, Asia, the Middle East and the westernmost areas of North and South America.
NASA's retired Earth Radiation Budget Satellite (ERBS) is expected to reenter Earth's atmosphere after almost 40 years in space.
