Pirs module and Progress MS-16 spacecraft missions completed

July 26, 2021

On Monday, July 26 2021, at 13:55:33 Moscow Time, the stack consisting of the docking compartment/module Pirs and Progress MS-16 logistics spacecraft undocked from the Zvezda Service Module of the International Space Station. Having moved it to a safe distance from the ISS, the specialists from the Lead Operations Control Team for the ISS Russian Segment (RSC Energia, which is a part of the State Corporation Roscosmos) started controlled de-orbit maneuvers.

In accordance with the sequence uploaded to the onboard computer of the logistics vehicle on command from the Mission Control Center at TsNIIMash (which is a part of Roscosmos), at 17:01 Moscow Time the main engine was fired to perform a retro burn. Having fired for 17.5 minutes, it imparted the stack a deceleration impulse of 120 m/s. At 17:42 Moscow Time the spacecraft/module stack re-entered the atmosphere, and 10 minutes later the debris that had not completely burned up sank into the spacecraft graveyard in the unnavigable part of the Pacific Ocean, 3.6 thou km away from Wellington and 5.8 thou km away from Santiago.

The Pirs module had been launched from Baikonur to the International Space Station on September 15, 2001. It was put into orbit using a Soyuz-U launch vehicle and the special cargo transportation spacecraft-module Progress M-DC1. On September 17, it successfully docked with the nadir port on the Service Module Zvezda of the ISS Russian Segment.

For 20 years it had been operated as the docking compartment for Russian spacecraft, both manned and unmanned: Soyuz and Progress, respectively. Until November 2020, cosmonauts performed spacewalks from Pirs, and in November 2020 and July 2021 the Russian crewmembers used for this purpose the Poisk module. Earlier, Roscosmos cosmonauts Oleg Novitski and Petr Dubrov had prepared the Russian module for undocking: Some of the operations were performed as part of extravehicular activities, and some as part of intravehicular activities.

Pirs became the firs station module to be undocked from it. This operation made it possible to free up the docking port on Zvezda Service Module of the ISS Russian Segment in order to receive the multipurpose laboratory module Nauka which had been launched from the Baikonur Cosmodrome on July 21, 2021. Its docking is currently scheduled for July 29.

The logistics vehicle Progress MS-16 was launched on February 15, 2021. On February 17 it docked with the Pirs module of the Russian Segment of the International Space Station. At the time the resupply spacecraft delivered to the ISS more than 2.5 tons of cargoes required to maintain its mission in manned mode and carry out the program of scientific and applied research in orbit. Upon completion of its mission, it carried out its main task of undocking and taking the docking compartment/module Pirs.
