This was a part of the mission to integrate the Nauka multipurpose laboratory module with the International Space Station
Russian cosmonauts Oleg Novitsky and Pyotr Dubrov have successfully complete their second spacewalk as part of the mission to integrate the Nauka multipurpose laboratory module with the International Space Station (ISS), the Russian space agency, Roscosmos, was broadcasting the spacewalk live.
"Airlock closed. The 50th planned spacewalk in the Russian ISS program is successfully finished," Roscosmos tweeted.

Expedition 65 flight engineer Oleg Novitskiy jettisoned a disc-shaped cable reel lid and piece of multi-layer insulation at the end of his and cosmonaut Pytor Dubrov’s spacewalk outside the International Space Station on Thursday, Sept. 9, 2021.
Novitsky and Dubrov left the ISS at 17:55 Moscow time on Thursday. They spent seven hours and 20 minutes outside of the station, completing all main and two additional tasks. In particular, the cosmonauts checked antennas of the Progress MS-17 cargo ship. They also connected the Ethernet local network cable to the Nauka module. Roscosmos later noted that the first test went fine. Novitsky and Dubrov also placed a platform with containers for the Biorisk-MSN experiment to study changes in bacterial and fungal associations that form microbiota of space hardware materials.

No damage on Progress MS-17 spacecraft antennas found during spacewalk
Cosmonaut Pyotr Dubrov found no damage on the Kurs docking navigation system antennas on the Progress MS-17 spacecraft during his spacewalk.
"I see no heavy damage to the reflectors and the antenna," Dubrov reported.
Pyotr Dubrov and Oleg Novitsky commenced their spacewalk operation at 17:55 Moscow time in order to integrate the Nauka science module to the ISS. The main operation is planned to take 6 hours and 26 minutes. Should the operation proceed ahead of schedule, three more groups of operations were planned that may last about three hours.
Shortly before the launch of the Progress MS-17 spacecraft, a problem was eliminated that forced cosmonauts to switch to a tele-operation control mode during the Progress MS-16 docking. On Thursday, Russian cosmonauts made sure that the antennas were not damaged.
