Expedition 68 Commander Sergey Prokopyev and Flight Engineer Dmitry Petelin, both of Roscosmos, concluded their spacewalk at 4:07 p.m. EST after 6 hours and 25 minutes.
Prokopyev and Petelin achieved their main goal by preparing a radiator on the Rassvet module for installation on the Nauka multipurpose laboratory module.
This was Prokopyev’s third career spacewalk and Petelin’s first. This was the tenth spacewalk at the station in 2022 and the 255th spacewalk for space station assembly, maintenance and upgrades.
On-Orbit Status Report
SR Extravehicular Activity (EVA) #55: During today’s EVA, FE-4 Sergey Prokopyev (EV1) and FE-5 Dmitry Petelin (EV2) performed a multitude of tasks, including preparing a radiator and an airlock to be installed on the Nauka Multipurpose Laboratory Module (MLM). The MRM2 hatch opened at 8:41 a.m. CT. The following tasks were carried out:
- Installation of the STRELA adapter on A/L FRGF on MRM1
- Removal of 6 (six) radiator retainers
- Exhaust of nitrogen from radiator hydraulic loops
- Installation of restraint on STRELA2
- Installation of a fastening system for large objects ([СККО]) on MLM
The phase elapsed time (PET) of this EVA was 6 hours and 25 minutes.
Payloads:
Integrated combustion grate/Solid fuel ignition and extinguishing (CIR/SOFIE): The crew gained access to the CIR and performed the necessary steps to remove a faulty duct flow sensor and replaced it. This is one of the component replacements required to make the CIR/SOFIE system ready to support science operations. The CIR facility includes an optical bench, a combustion chamber, fuel and oxidizer monitoring, and five different cameras to perform combustion investigations in microgravity. SOFIE is a hardware insert for the CIR that enables a wide range of solid material combustion and fire extinguishing studies.
Systems:
Compound Specific Combustion Analyzer (CSA-CP) Verification: Today, the crew installed new batteries in newly replenished CSA-CPs, reset the internal clock and data logger for each monitor, and allowed all units to degas in an open environment. CSA-CPs are used for continuous monitoring of carbon monoxide levels on the ISS. CSA-CPs can also provide real-time readings after a combustion event and subsequent cleanup efforts.
Columbus centralized cabin filter (CCF) R&R: The crew replaced the High Efficiency Particulate Absorbent (HEPA) CCF in the Columbus Cabin Heat Exchanger (CHX). The CCF is a HEPA filter that cleans all the air entering the CHX. To control the reproduction of accumulated microbes, the filter has a life in orbit of one year.
Cygnus Cargo Transfer Operations and Cargo Dragon Prepack: The crew continued to unload scientific experiments, crew supplies and equipment from the Cygnus NG-18 cargo vehicle. The crew is about to complete the unpacking of Cygnus, which will eventually lead to crew activities to repack the vehicle with trash and unwanted items from the ISS. At the same time, the crew also pre-packed and prepared items to return in anticipation of the next Cargo Dragon vehicle.
SpX-26 Dragon Rendezvous Review Computer Based Training (CBT): Today the crew reviewed rendezvous and proximity operations as well as videos of nominal and non-nominal Dragon approaches. The crew also used Dynamic Onboard Ubiquitous Graphics (DOUG) to review docking target assessment. CBT examination activities are carried out as part of the training and preparation for the arrival of SpX-26.
