NASA's Swift observatory, first launched in 2004, is anticipated to fall back to Earth after a failed rescue mission. The telescope, functioning for more than two decades, will disintegrate upon re-entry. A significant portion of the debris will incinerate in the atmosphere. Experts estimate that the impact area might span 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 Responsible If Debris Results in Harm?
