NASA's Swift observatory, launched in 2004, is anticipated to fall back to Earth after an unsuccessful rescue attempt. The telescope, operational for over two decades, will break apart during re-entry. Most debris will burn up in the atmosphere. Experts forecast that the impact zone may encompass over 80% of Earth's surface. Authorities are keeping a close watch to evaluate risks to inhabited regions. The exact location of impact is still unclear. NASA's Swift Observatory Falling to Earth: Who Is Responsible If Debris Results in Harm?
