A nearly 40-year-old U.S. Aeronautics and Space Administration (NASA) Earth radiation monitoring satellite is expected to fall to Earth in the coming days, but the risk is considered low.

Most of the nearly 2.5-ton satellite will burn when it falls into the atmosphere, but some pieces may not be completely burned, the AP cited NASA as saying. However, NASA has stated that the possibility of satellite fragments causing harm to humans is “very slow”. According to the above agency, the rate of human beings at risk is only 1/9. 400.
NASA predicts The satellite could fall at 6:40 p.m. on January 8 (US Eastern Time, equivalent to 6:40 a.m. on January 9, Vietnam time).. The prediction error can be up to 17 hours.
Meanwhile, an aerospace company Aerospace company (United States) predicted The time falls on the morning of January 9 (equivalent to the evening of January 9, Vietnam time).
This Earth radiation monitoring satellite called ERBS was launched in 1984 by the space shuttle Challenger. At that time, ERBS was launched by Mrs. Sally Ride, the first woman in space, using the ship’s robotic arm.
Also on that flight, Kathryn Sullivan – another astronaut – became the first American woman to walk in space.
Although scientists initially planned to use the satellite for only two years, the device was able to operate until 2005, when the device was put into service. “retirement”.
With ERBS, scientists can study how the Earth absorbs and reflects energy from the Sun, as well as assess the state of the ozone layer, water vapor or NO2 gas in the atmosphere.
