The European satellite ERS-2 should fall back to Earth on Wednesday. The chance of one of these debris hitting a person on the ground is less than one in a hundred billion, according to the ESA blog dedicated to the mission.
The final re-entry of the satellite is forecast for Wednesday at 11:14 GMT, with an uncertainty margin of plus or minus 15 hours. Most of the 2.3 tonnes of E RS-2 is expected to burn up when it reaches the lower layers of the atmosphere, at an altitude of around 80 km.
