NASA maps possible meteorite drop zone after daytime Texas fireball

A rare daytime meteor exploded over the Houston area on March 21, with NASA's ARES releasing a provisional strewn-field map showing where meteorite fragments may have fallen, including heavier shards (about 1 kg) likely in red zones between Willowbrook and Northgate Crossing; the event produced a bright flash detectable by GOES satellites and ground-level pressure waves. The map is tentative and warns against trespassing as residents search private property; the piece also notes a separate daytime fireball in Ohio on March 17.

Brazil Uncovers Vast Field of Ancient Space Glass

Scientists have identified hundreds of tektites—glass droplets formed when a meteorite melted surface rock—over a 900-km region in Brazil, named geraisites. Dating places the material up to about 6.3 million years old and reveals an ancient crustal source from the São Francisco Craton. No nearby crater has been found, but the discovery expands Brazil's impact history and suggests tektites may be more common than previously thought.
