NASA Confirms a 1.5-Meter Meteorite Exploded in the Skies Over New England on May 30
In recent days, many people in the New England area witnessed the entry of a meteorite into the Earth's atmosphere and its explosion, which generated a loud noise audible from a great distance. NASA officially confirmed the phenomenon that occurred on May 30 at 20:06 (Italian time) with data collected not only from surveillance cameras and dashcams but also from the GOES-19 geostationary weather satellite (also called GOES-U) of the National Oceanic and Atmospheric Administration.
According to the recordings, the meteorite likely disintegrated at an altitude of about 50 km in a sky area between Massachusetts and New Hampshire. Data indicates that the object had a diameter of about 1.5 meters with a mass of 5.6 tons, entering the atmosphere at a high speed of approximately 68,000 km/h. Due to its trajectory, entry angle, and speed, the meteorite traveled about 42 km before disintegrating, generating a debris fall in the Cape Cod Bay area. Despite being a relatively modest-sized object, the energy released was equivalent to 0.23 kt (or 230 tons of TNT).
As explained by NASA, this period (usually from February to April) is the most favorable for observing the entry of meteorites into the atmosphere in the northern hemisphere. The reasons are unclear, but events see an increase of 10% to 30% during these weeks. One possibility is that our Planet is passing through an area richer in large debris that then re-enter the atmosphere, generating these events. The agency emphasizes that the presence of a greater number of recording devices may also contribute to increasing national and international visibility.
There are different types of space objects with names varying based on characteristics. For instance, a meteoroid is a small rock, usually a fragment of a comet or asteroid. Then there is a meteor, which refers to the bright trail seen in the sky when a meteoroid enters the atmosphere.
On Saturday, May 30, the Geostationary Lightning Mapper (#GLM) on board @NOAA's #GOESEast (#GOES19) detected a bright flash near Massachusetts. But this wasn't lightning—it was a bolide, a bright meteor that exploded in Earth's atmosphere. Residents throughout the region witnessed this event.
The meteor shower cannot be missed when meteoroids of a common origin (for example, when Earth passes through debris left by a comet) enter the atmosphere. A meteorite, like the one reported, is when the rock is of sufficient size and characteristics to reach the ground. A bolide, however, is even brighter and more visible, especially when the phenomenon occurs at night, being brighter than planets like Venus.
