A large, cylindrical metallic object descended from the sky and landed in a private field in Puerto Tirol, Chaco province, Argentina, on September 25, 2025. The discovery, made around 6:30 PM in an area known as Ex Campo Rossi, has initiated an intensive investigation by local authorities and specialized technical personnel to determine the object's origin.
The artifact, measuring approximately 1.70 meters in length and 1.20 meters in diameter, is constructed from carbon fiber. It features a 40-centimeter opening at one end and a valve system at the other, with an inscribed serial number. Following the discovery, neighbors alerted authorities, leading to a swift response from the Resistencia Firefighters Division and the Puerto Tirol Police Station. Explosives specialists confirmed the artifact posed no immediate danger, and a 30-meter safety perimeter was established as investigations commenced.
Initial hypotheses suggest the object could be debris from a satellite or advanced technological equipment, a possibility consistent with the growing global concern over space debris. An estimated 200 tons of space hardware re-enter Earth's atmosphere annually in uncontrolled descents. Recent incidents include debris from a SpaceX Falcon 9 rocket found in Poland in February 2025 and fragments from a Chinese Long March 3B rocket discovered in Santa Fe, Argentina, in May 2025.
The object's composition of carbon fiber and the presence of a valve system align with components used in aerospace technology. While sparking curiosity and comparisons to historical meteorite finds in Chaco's Campo del Cielo region, this metallic cylinder is believed to be a product of human technological endeavors, unlike natural celestial bodies. The event highlights the increasing challenges of managing space junk and the need for robust international regulations governing the re-entry and disposal of space materials.
Authorities have cautioned residents against approaching or touching any similar unidentified metallic objects and urged them to report any new discoveries immediately. The investigation is ongoing, with specialized technical personnel working to ascertain the object's precise source and purpose.
