MOSCOW, May 12. Russian cosmonauts Sergei Prokopiev and Dmitry Petelin went into outer space from the ISS to prepare for operation the radiator, which they had previously transferred to the Nauka module, Roscosmos reported.
«Sergey Prokopiev and Dmitry Petelin opened the day off hatch. The astronauts will spend more than 6 hours on the outer surface of the ISS,» the Roscosmos telegram channel says. url=»https://ria.ru/20230503/skafandr-1869501254.html» data-title=»New suits for spacewalks to be made in Russia»>
Prokopiev and Petelin will first of all dismantle two couplers from the radiator and open its panels. Then they will fill the hydraulic circuits of the radiator with coolant and combine them with the Nauka module's thermal management system. The cosmonauts will also install two halyards on the ERA remote manipulator.
This is the 68th spacewalk under the Russian ISS program and the third for the Russians in 2023. For Prokopyev it was the sixth outing in his career, for Petelin it was the fourth.
Earlier, the commander of the Russian cosmonaut corps, Oleg Kononenko, said in an interview that in 2023 Prokopyev and Petelin could conduct up to five spacewalks.
The first joint spacewalk by Prokopyev and Petelin took place on November 17 last year. Then they installed a Large Object Attachment Tool (LSC) on the Nauka multi-purpose laboratory module, which will be needed in the future for scientific experiments.
Later, work overboard was postponed due to the depressurization of the Soyuz MS-22, the crew was waiting for the arrival of a new ship. The second time Prokopyev and Petelin went into outer space was already on April 19: using the ERA manipulator, they transferred the radiator from the Rassvet module to Nauka, undocked the radiator cables from the module and unfixed it.
On the night of 4 In May, the Russian cosmonauts made their third exit and, using a manipulator, transferred the lock chamber from Rassvet to Nauka — with the help of it, it will be possible to place equipment for experiments outside the station without leaving the ISS. A special conveyor will extend from it, from which the equipment can be captured by the ERA manipulator and installed on the SKKO.
