Nasa satellite which spent 39 years in space to fall from sky this weekend
A Nasa satellite that has been orbiting earth since 1984 is set to fall from the sky this weekend.
The 38-year-old retired satellite is unlikely to hurt anyone, with the space agency saying the chance of wreckage falling on anybody is “very low”.
Most of the 5,400lb (2,450-kilogram) satellite will burn up upon re-entry, according to Nasa, although some pieces are expected to survive.
The space agency put the odds of injury from falling debris at about 1-in-9,400.
The science satellite is expected to come down on Sunday night, give or take 17 hours, according to the United States Defence Department.

The Earth Radiation Budget Satellite, known as ERBS, was launched in 1984 aboard space shuttle Challenger.
Although its expected working lifetime was two years, the satellite kept making ozone and other atmospheric measurements until its retirement in 2005.
The ERBS studied how Earth absorbed and radiated energy from the sun.

America’s first woman in space, Sally Ride, released the satellite into orbit using the shuttle’s robot arm.
That same mission also featured the first spacewalk by a US woman, Kathryn Sullivan.
It was the first time two female astronauts flew in space together.
It was the second and final spaceflight for Ms Ride, who died in 2012.
