Expedition 67 Commander Oleg Artemyev and Flight Engineer Denis Matveev, both of Roscosmos, concluded their spacewalk at 5:12 p.m. EDT after 7 hours and 47 minutes.

Artemyev and Matveev completed their major objectives, which included relocating an external control panel for the European robotic arm from one operating area to another and testing a rigidizing mechanism on the arm that will be used to facilitate the grasping of payloads. In addition, the duo extended a Strela telescoping boom from the Zarya module to the Poisk module.

Additional spacewalks are planned to continue outfitting the European robotic arm and to activate Nauka’s airlock for future spacewalks. The work on the European robotic arm will be used to move spacewalkers and payloads around the Russian segment of the station.

This was the eighth spacewalk in Artemyev’s career, and the fourth for Matveev. It was the eighth spacewalk at the station in 2022 and the 253rd spacewalk  for space station assembly, maintenance, and upgrades.

RS Extravehicular Activity (EVA) #54A: Today, Oleg Artemyev (EV1) and Denis Matveev (EV2) performed RS EVA #54A with Sergey Korsakov supporting as the IV operator. Hatch opening occurred at 8:25 AM CT. The trio performed several tasks to configure and test the European Robotic Arm (ERA) for operations on the station’s Russian Segment. The final Phase Elapsed Time (PET) from today’s EVA was 7 hours and 47 minutes and the following tasks were completed:

The following tasks were deferred from today’s EVA:

ERA is currently in the following configuration:

Manufacturing Device (ManD): In response to unexpected print tray temperature readings seen previously, today the crew exchanged the current print tray for a new print tray. ManD enables the production of components on the ISS for both NASA and commercial objectives. Parts, entire experiments, and tools can be created on demand utilizing the ManD printer that is installed into an EXPRESS locker location.  ManD is capable of producing parts out of a wide variety of thermopolymers including engineered plastics.

Treadmill 2 (T2) Monthly Inspection: The crew completed a regular maintenance inspection to ensure the T2 exercise device is in good operational condition. The crew inspected all four Snubber Arms for any sign of free play as well as make any necessary adjustments to reduce the free play.

Life Support Rack and Oxygen Generation Assembly (LRS/OGA) Rack Preparation: Today, the crew demated LSR fluid and electrical umbilicals for LSR rack rotation and transfer starting on Monday. Also, the crew gathered the necessary hardware for the LSR/OGA rack swap.

Today’s Ground Activities: All activities are complete unless otherwise noted.

Today’s Planned Activities: All activities are complete unless otherwise noted.
