NASA's Swift observatory, originally launched in 2004, is anticipated to fall back to Earth after a rescue mission that was not successful. The telescope, functioning for more than two decades, will disintegrate upon re-entry. Most debris will burn up in the atmosphere. Experts estimate that the impact area might span over 80% of Earth's surface. Authorities are observing the scenario to gauge threats to populated zones. The exact location of impact is still unclear. NASA's Swift Observatory Falling to Earth: Who Is Responsible If Debris Results in Harm?
