Undoing of cabling between Pirs and Zvezda, transferral of airlock hardware from Pirs to Poisk.
Thus, the 48th planned spacewalk under the Russian program will be devoted to preparations for undocking the Pirs docking compartment-module, to which the Nauka module will subsequently arrive. The Russian ISS crew members will disconnect the Kurs-P antenna-feeder device (AFD) of the Zvezda service module from the Kurs-P of the Pirs module and connect it to the Kurs-P AFU of the nadir docking assembly of the Zvezda module transition compartment ". In addition, they will transfer the GStM2 cargo boom from the Pirs module to the storage position on the Search module and dismantle the docking target at the Pirs module docking station.In addition to preparations for undocking the Pirs module, Roskosmos cosmonauts will replace the replaceable fluid flow control panel on the Zarya functional cargo block, and if time is available, the Endurance and Test space experiment panels will be installed on the small research module "Search" for the Russian segment of the International Space Station.https://www.roscosmos.ru/29696/

MOSCOW, April 30. / TASS /. Russian cosmonauts Oleg Novitsky and Pyotr Dubrov will enter open space from the ISS on June 2. This was reported to TASS on Friday by the press service of Roscosmos."The release will take place on June 2," the press service noted.As specified in Roskosmos, the crew members will have to prepare the docking compartment before the arrival of the multifunctional laboratory module "Science" and replace the replaceable panel of the fluid flow regulator of the thermal regime of the functional cargo block.On Thursday, materials from the magazine "Russian Space" (the official publication of Roscosmos) reported that according to the program, the next spacewalk with the participation of Novitsky and Dubrov was to take place in May. In September, they will make two spacewalks to connect electrical cables between the Nauka and Zvezda modules.
Spacewalk on June 2In accordance with the schedule of work on the Russian segment of the International Space Station June 2, 2021 will be the 48th planned spacewalk (EVA number 48), which will perform cosmonauts Roscosmos Oleg Novitsky and Pyotr Dubrov.Preliminary cyclogram of VKD-48 Replacement of the replacement flow regulator panel on module "Zarya" and pushing the pressurized container away from module "Poisk"; transfer of the cargo upgraded boom from the "Pirs" module to the storage position on the "Search" module; disconnecting the antenna-feeder device "Curs-P" of the "Star" module from the "Curs-P" of the "Pirs" module; connecting "Curs-P" of "Zvezda" module to "Curs-P" antenna-feeder device of nadir docking unit of transition compartment; removal of halyard-transfer unit of small-diameter working compartment of module "Zvezda"; installation of necessary equipment for scientific space experiments "Test" and "Endurance" on the outer surface of the module "Search".
