Meteorite fragment recovered in North Houston after rare daytime fireball; scientists continue searches

A roughly one-ton meteoroid, about three feet wide, tore through the atmosphere above North Houston on March 21 and sent fragments raining down across a 12-mile corridor from Louetta to Spring. The blast released energy equivalent to 26 tons of TNT, drove sonic booms across the region, and pushed at least one fragment straight through a residential roof, where it came to rest in a bedroom.

Within days, scientists from NASA, Rice University, and the Lunar and Planetary Institute were walking those neighborhoods with eyes down. David Gonzales, a meteorite hunter from San Antonio, was first to pull a stone from the predicted fall zone. NASA planetary scientist Marc Fries, who tracks meteorite falls using weather radar and seismic data at NASA Johnson Space Center, recovered a 46-gram piece in a grassy strip near the Barbara Bush Branch Library along Cypresswood Drive: dark gray outside, lighter inside, with a fresh fusion crust where its surface had melted during descent. Neeraja Chinchalkar, a postdoctoral researcher at the Lunar and Planetary Institute, found a separate three-gram fragment. A local family recovered the largest piece yet, roughly 60 grams, while at least five stones have been pulled from Collins Park alone. About a dozen fragments total had been documented as of early April.

Early lab analysis points to an LL chondrite classification, a subgroup of ordinary chondrites with low total iron and low metallic content. These are among the oldest accessible materials in the solar system, dating to roughly 4.55 billion years ago. The Houston fragments also show extensive dark veins that LPI researchers say could indicate the rock endured unusual thermal events across its long history. Bidong Zhang, an assistant professor in Rice University's Department of Earth, Environmental and Planetary Sciences, is conducting ongoing analysis alongside LPI Senior Scientist Prajkta Mane.

NASA's updated strewn field maps identify Wimbledon Estates, Wimbledon Champions Estates, and Wimbledon Centre Court Estates, the subdivisions just north of Cypresswood Drive near Collins Park, as likely sites for additional unrecovered fragments. A separate stone weighing about 2.2 pounds struck a house in the Ponderosa Forest subdivision. Fries has encouraged homeowners across the zone to check their lawns, roofs, and pools for black rocks with a light gray interior.

Documenting a find correctly matters on two levels: scientific and legal. In Texas, a meteorite found on private property belongs to the landowner. But documented provenance, a precise record of where and how a stone was found before it was moved, is what allows Rice or LPI researchers to tie a sample to a specific point in the strewn field and eventually publish peer-reviewed findings. Moving or cleaning a fragment before photographing it in place can permanently sever that chain. Residents who find a suspected piece should contact researchers at Rice University's Department of Earth, Environmental and Planetary Sciences or the Lunar and Planetary Institute in Houston before disturbing it.

The fireball struck at 4:30 p.m. on a clear Saturday, drawing more than 100 eyewitnesses whose accounts, combined with NOAA radar data, let scientists build a strewn field model within hours. Daytime falls that deposit recoverable fragments are uncommon; the combination of broad daylight, a dense urban witness network, and a rapid scientific response makes this one of the better-documented meteorite recoveries in recent memory and keeps the search zone live for anyone willing to look.
