NASA's Swift observatory, launched in 2004, is anticipated to fall back to Earth after an unsuccessful rescue attempt. The telescope, operating for more than two decades, will fall apart during its descent. 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 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 Accountable If Debris Leads to Damage?
