"Undocking of the Pirs compartment-module with the Russian segment of the ISS is scheduled for 13:56 Moscow time on July 26, and the fall of incombustible elements in the Pacific Ocean - at 17:51 Moscow time on the same day," wrote the head of Roscosmos Dmitry Rogozin in his Telegram channel.
The Pirs module was docked to the port of the Zvezda service module.
Later, its place should be taken by the multipurpose laboratory module "Science", which is already in orbit.
Initially, the sinking of the "Pirs" was scheduled for July 23, but was postponed.
Earlier Rogozin said that testing of the Kurs rendezvous system at the Nauka multipurpose laboratory module had been carried out routinely.
