Warsaw: Debris from a SpaceX Falcon 9 rocket that blasted off in the United States on February 1 entered the Earth's atmosphere over Poland on Wednesday, the Polish space agency said.
A 1.5 metre by one metre (five feet by three feet) chunk from an unidentified object was found near the western city of Poznan, but no casualties or damage was reported, police said.
The Polish Space Agency (POLSA) said a stage of the Falcon 9 R/B rocket made "an uncontrolled re-entry into the atmosphere" at about 0346 GMT.
It said the rocket was part of a Space X Starlink Group launch from Vandenberg Air Force Base in California on February 1.
The launch was to put Starlink satellites into a low-level orbit.
The debris left spectacular luminous trails visible in the sky in western Poland, witnesses said. According to police, the chunk of debris was found in the grounds of a warehouse near Poznan.
A police spokesman, Lukasz Paterski, said police and firefighters were working to find the origin of the debris. He said it was possible the object came from a SpaceX rocket.
POLSA spokeswoman Agnieszka Gapys said the agency was speaking with SpaceX, which is controlled by Elon Musk, the world's richest man, about the debris, PAP news agency reported.
Polish media said the composite material found near Poznan resembled a Falcon 9 fuel tank.
