NASA's Swift observatory, originally launched in 2004, is anticipated to fall back to Earth after a failed rescue mission. The telescope, functioning for more than two decades, will break apart during re-entry. Majority of the debris will combust in the atmosphere. Experts forecast that the impact zone may encompass over 80% of Earth's surface. Authorities are observing the scenario to gauge threats to populated zones. The exact location of impact has not been determined. NASA's Swift Observatory Falling to Earth: Who Is Accountable If Debris Leads to Damage?
