Dragon Departing Friday; Cosmonauts Clean Up After Spacewalk

The Expedition 67 crew will wait an extra day before seeing a U.S. space freighter depart the International Space Station. In the meantime, the cosmonauts are cleaning up following a shorter-than-planned spacewalk after a power issue on a Russian Orlan spacesuit.

Mission managers representing NASA and SpaceX waved off Thursday’s undocking of the Dragon cargo craft due to adverse weather conditions at the splashdown site off the coast of Florida. Dragon is now due to leave the Harmony module’s forward port at 11:05 a.m. EDT on Friday.

Four of the station’s astronauts including Kjell Lindgren, Bob Hines, and Jessica Watkins, all from NASA, with Samantha Cristoforetti of ESA (European Space Agency), will finish packing Dragon with critical research samples early Friday morning before closing the commercial resupply ship’s hatch. Dragon is scheduled to parachute back to Earth on Saturday loaded with over 4,000 pounds of cargo including completed scientific experiments for analysis. NASA TV, on the agency’s app and website, begins its live undocking coverage at 10:45 a.m. on Friday.

During a four-hour and one-minute spacewalk on Wednesday, Commander Oleg Artemyev and Flight Engineer Denis Matveev installed a pair of cameras on the European robotic arm (ERA) and removed parts attached to the arm’s end effector. Today, the cosmonauts powered down their Orlan spacesuits and removed suit components. Flight Engineer Sergey Korsakov reconfigured the Poisk module back to normal operations.

Just over two hours after Thursday’s spacewalk began, Artemyev informed Russian mission controllers his spacesuit was experiencing abnormal battery readings. Mission controllers directed Artemyev to return to the Poisk’s airlock and connect his spacesuit to the station’s power supply. Matveev continued his tasks before cleaning up and heading back to Poisk after managers called off the robotic maintenance excursion. Korsakov maneuvered the ERA to a safe post-spacewalk configuration while the cosmonaut spacewalkers were never in any danger.

Dragon Cargo Craft Undocking Postponed to Friday

At the conclusion of an early morning weather briefing, NASA and SpaceX are postponing the Thursday, Aug. 18 undocking of a SpaceX Dragon cargo resupply spacecraft from the International Space Station due to unfavorable weather conditions, including an elevated chance of precipitation at the splashdown sites. Mission teams now are targeting to undock the uncrewed Dragon spacecraft from the space station at 11:05 a.m. EDT Friday, Aug. 19.

NASA will provide coverage of Dragon’s undocking and departure on NASA Television, the NASA app, and the agency’s website beginning at 10:45 a.m. EDT. Watch online at:

After re-entering Earth’s atmosphere, the spacecraft will make a parachute-assisted splashdown off the coast of Florida on Saturday, Aug. 20. NASA TV will not broadcast the splashdown, and updates will be posted on the agency’s space station blog.v

Spacewalk Concludes After Abnormal Battery Readings

Expedition 67 Commander Oleg Artemyev and Flight Engineer Denis Matveev, both of Roscosmos, concluded their spacewalk at 1:54 p.m. EDT after 4 hours and 1 minute.

During the spacewalk, the two cosmonauts completed the installation of two cameras on the European robotic arm prior to Artemyev’s Orlan spacesuit showing abnormal battery readings about 2 hours and 17 minutes into the extravehicular activity. Mission Control-Moscow instructed Artemeyev to return to the Poisk airlock to connect to the space station’s power supply. Cosmonaut Sergey Korsakov, inside the station, placed the European robotic arm in a safe configuration, and Matveev safely returned to the Poisk airlock after completing some final clean-up activities outside of the International Space Station. The duo was never in any danger during the operations.

NASA TV announces spacewalk is ending early (@Space_Station Twitter)

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 seventh spacewalk in Artemyev’s career, and the third for Matveev. It was the seventh spacewalk at the station in 2022 and the 252nd spacewalk for space station assembly, maintenance, and upgrades.

Russian Spacewalk Ends Early After Battery Power Issue

Expedition 67 Commander Oleg Artemyev and Flight Engineer Denis Matveev, both of Roscosmos, were instructed by Russian flight controllers to end the Aug. 17 spacewalk at the International Space Station due to a battery power issue on Artemyev’s Orlan spacesuit.

During the spacewalk, the two cosmonauts completed the installation of two cameras on the European robotic arm prior to Artemyev’s Orlan spacesuit showing abnormal battery readings. Mission Control-Moscow instructed Artemyev to return to the Poisk airlock to connect to the space station’s power supply. Cosmonaut Sergey Korsakov, inside the station, is placing the European robotic arm in a safe configuration, and Matveev has just returned to the Poisk airlock. The duo was never in any danger during the operations.

Spacewalkers Exit Station to Continue Outfitting European Robotic Arm

Expedition 67 Commander Oleg Artemyev and Flight Engineer Denis Matveev, both of Roscosmos, began a spacewalk at 9:53 a.m. EDT to continue outfitting the European robotic arm on the International Space Station’s Nauka laboratory by opening the hatch of the Poisk docking compartment airlock. Coverage of the spacewalk continues on NASA Television, the NASA app, and the agency’s website.

The duo is installing cameras on the European robotic arm, relocating an external control panel for the arm from one operating area to another, removing launch restraints near the two end effectors or “hands” of the arm, and testing a rigidizing mechanism on the arm that will be used to facilitate the grasping of payloads.

Artemyev is wearing a Russian spacesuit with red stripes, while Matveev is wearing a Russian suit with blue stripes. This will be the seventh spacewalk in Artemyev’s career, and the third for Matveev. It will be the seventh spacewalk at the station in 2022 and the 252nd spacewalk for space station assembly, maintenance, and upgrades.
