The flaming debris was part of the upper stage of a SpaceX Falcon 9 rocket that launched 22 of the company's Starlink internet satellites to orbit from California on Feb. 1, experts say. The Falcon 9 upper stage is expendable (unlike the rocket's first-stage booster) but is designed to be brought down in a controlled fashion shortly after launch.

Debris from a SpaceX Falcon 9 rocket re-entered Earth`s atmosphere over Poland, landing near Poznan. No injuries or damage reported.

SpaceX crews are preparing to launch a Falcon 9 rocket Tuesday from Florida’s Space Coast. The launch is set for 1:53 p.m. from Space Launch Complex 40 at the Cape Canaveral Space Force Station. The launch is aiming to send another batch of Starlink satellites into orbit.
