NASA's Swift observatory, first launched in 2004, is expected to re-enter Earth's atmosphere after an unsuccessful rescue attempt. The telescope, operational for over two decades, will break apart during 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 monitoring the situation to assess risks to populated areas. The exact location of impact remains uncertain. NASA's Swift Observatory Falling to Earth: Who Is Accountable If Debris Leads to Damage?
