CBRN event in Argentina on Tue 30th September 2025

A mysterious “toxic” space capsule crashed down to earth and landed in a farm in rural Argentina, leaving locals bewildered. The large cylinder, some 1.7 metres long and covered in feathery black strands of fibre, was found in a field in Puerto Tirol late on Thursday. A bomb squad was called to the scene after farmer Ramón Ricardo González, 47, reported the unusual discovery to police. Chaco Police Chief Fernando Romero told NG Federal that the box was “made of carbon fibre and is very toxic”, adding that the tank was filled with hydrazine, which is primarily used as a rocket fuel. Responding authorities found the box, apparently scratched and scorched from re-entry, inscribed with a serial number, according to Argentinian outlet Novedades del Sur. Police enlisted the help of Ruben Lianza, director of Argentina’s Aerospace Research Centre (CIAE), who helped identify the tank and warned it could release toxic dust if touched, Diario Chaco reports. Photos circulating in local media showed officials on the scene wearing ventilators and protective gear. Experts said the capsule was likely a form of fuel tank, known as composite overwrapped pressure vessel (COPV), according to Metro. NASA uses such vessels to “contain high pressure fluids in propulsion”, as well as for science experiments and life support applications. Police cordoned off the scene in Puerto Tirol and warned residents that more fragments could yet fall from the sky at the advice of the Air Force. A specialist team was expected to carry out the removal on Friday. There has been no official confirmation as to whether the capsule is indeed space debris. Metro cited reports noting the field was beneath the known flight path of a Chinese Jielong 3 rocket.
