NASA's Swift Observatory Anticipated to Re-enter Earth's Atmosphere Today

NASA's Neil Gehrels Swift Observatory, a 3,200-pound spacecraft launched 22 years ago, is projected to re-enter Earth's atmosphere today, November 4, 2026. While most of the satellite is expected to burn up, some debris may reach the ground, with re-entry estimated around 10:19 UTC ± 2 hours. A previous attempt to boost its orbit failed, and the risk of harm to anyone on Earth is approximately 1 in 2,100.
