Following the undocking, the module and spacecraft were moved to a safe distance. Controllers used Progress’s thrusters to slow the objects down, in a procedure that occurred at 10:01 a.m. EDT. What was left after reentry into Earth atmosphere fell into “a non-navigable area of the Pacific Ocean,” according to Roscosmos. 

With Pirs and Progress gone, the port on the Earth-facing side of the Russian segment is ready to receive Nauka, which means “science” in Russian. The new segment will provide more room for science experiments, cargo, and equipment. Nauka is also delivering Europe’s new robotic arm, which will service the Russian segment of the space station.
