Why did NASA's Swift Observatory fall to Earth?
NASA's Neil Gehrels Swift Observatory, a 3,200-pound spacecraft launched in November 2004, met its end on November 4, 2026, burning up in Earth's atmosphere over Indonesia. The observatory was designed to study powerful cosmic explosions like gamma-ray bursts, but atmospheric drag, intensified by recent solar activity, caused it to descend from orbit. While most of the observatory likely vaporized, the uncontrolled reentry raised questions about space debris and the safety of aging satellites.
