A 5,000-pound satellite is expected to fall to Earth this week

The agency’s Space Debris Office, along with an international surveillance network, is monitoring and tracking the Earth-observing ERS-2 satellite, which is predicted to make its reentry at 6:14 a.m. ET Wednesday, with a 15-hour window of uncertainty. The ESA is also providing live updates on its website.
“As the spacecraft’s reentry is ‘natural’, without the possibility to perform manoeuvers, it is impossible to know exactly where and when it will reenter the atmosphere and begin to burn up,” according to a statement from the agency.
The exact time of the satellite’s reentry remains unclear due to the unpredictability of solar activity, which can change the density of Earth’s atmosphere and how the atmosphere tugs on the satellite. As the sun nears its 11-year cycle’s peak, known as solar maximum, solar activity has been ramping up. Solar maximum is expected to occur later this year.
