Overview
- A meteoroid fractured above the Massachusetts–New Hampshire border on Saturday, May 30, producing a bright flash and loud detonations felt across the two states.
- NASA measured the breakup energy at roughly 300 tonnes of TNT, estimated the speed at about 120,000 km/h, and placed the fragmentation near 64 kilometres altitude.
- The agency identified the object as a natural meteoroid and said it was not linked to any active meteor shower or to satellite or space-debris reentry.
- Residents reported houses shaking and strong, audible blasts on social media, while news coverage and NASA gave no reports of confirmed injuries, damage, or recovered fragments.
- Satellite observations and agency statements helped confirm the event, and scientists say the TNT-equivalent energy explains the wide-area shock effects and will guide follow-up monitoring for fragments or similar airbursts.
