Overview
- NASA said a roughly 3‑foot natural object entered the atmosphere on Saturday and fragmented about 40 miles above northeastern Massachusetts and southeastern New Hampshire, producing a bright daytime fireball.
- Analysts estimated the rock was traveling about 75,000 miles per hour and released energy near 300 tons of TNT, which created loud double booms and rattled homes across eastern Massachusetts and neighboring states.
- NOAA’s GOES‑19 satellite recorded an anomalous flash at the same time that dozens of eyewitness reports to the American Meteor Society corroborated, and the U.S. Geological Survey recorded no earthquake activity consistent with an atmospheric sonic boom.
- State and local officials reported no injuries or structural damage after a surge of emergency calls, and NASA and others say any surviving fragments likely fell into the middle of Cape Cod Bay where recovery is unlikely due to depth and sea conditions.
- Although events of this scale are not rare in planetary terms, the multi‑sensor data and videos gathered will help scientists reconstruct the trajectory and improve understanding of how small near‑Earth objects break up in the atmosphere.
