NASA's Swift observatory, launched in 2004, is expected to re-enter Earth's atmosphere after an unsuccessful rescue attempt. The telescope, operational for over two decades, will fall apart during its descent. A significant portion of the debris will incinerate in the atmosphere. Experts predict the impact zone could cover over 80% of Earth's surface. Authorities are keeping a close watch to evaluate risks to inhabited regions. The exact location of impact has not been determined. NASA's Swift Observatory Falling to Earth: Who Is Accountable If Debris Leads to Damage?
