This Sunday a 2.5-ton satellite fell to Earth and NASA doesn’t know where it will fall

This Sunday, a 2.5-ton satellite will fall to Earth after nearly 40 years of service. NASA warns that even if very small, it is likely to be space junk to harm something

“Earth Radiation Balancing Satellite (ERBS) is expected to re-enter the Earth’s atmosphere After nearly four decades in space. During those 21 years, ERBS actively investigated how Earth absorbed and radiated energy from the Sun and measured stratospheric ozone, water vapor, nitrogen dioxide and aerosols, NASA said in a statement.

“The Defense Department predicts that a 5,400 lb (2,449 kg) satellite will re-enter the atmosphere Sunday, January 8th at around 6:40PM EST (00:40 hours in the Iberian Peninsula on Monday the 9th) with an uncertainty of +/- 17 hours. NASA and the Department of Defense will continue to monitor re-entry and update predictions, the statement said.

“NASA expects most of the satellite to burn up as it travels through the atmosphere, but some components are expected to survive re-entry. The risk of harm to anyone on Earth is very low: about 1 in 9,400Says the agency.

launched from Space Shuttle Challenger on October 5, 1984The ERBS spacecraft was part of a three-satellite mission by NASA. It carried three instruments, two to measure Earth’s radioactive energy balance and one to measure stratospheric constituents including ozone.

energy balance, balance between the amount of energy from the sun that the earth absorbs or radiatesis an important indicator of the health of the climate, and understanding it can also help reveal weather patterns, NASA explains.
