Expedition 69 Commander Sergey Prokopyev (left) is conducting his sixth career spacewalk. Flight Engineer Dmitri Petelin (right) is conducting his fourth spacewalk.
NASA Television coverage is underway for today’s spacewalk with Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin. The duo will deploy a radiator on the on the International Space Station’sNauka science module, connect electrical, mechanical, and hydraulic lines, and fill a pair of colling loops on the radiator with coolant. Coverage of the spacewalk is on NASA Television, the NASA app, and the agency’s website.
Prokopyev and Petelin will exit out of the Poisk module at about 11:55 a.m. EDT. Prokopyev is wearing the Orlan spacesuit with red stripes, while Petelin is wearing the suit with blue stripes.
This is the sixth spacewalk in Prokopyev’s career, and the fourth for Petelin. It is the sixth spacewalk at the station in 2023 and the 263rd spacewalk for space station assembly, maintenance, and upgrades.

Four Expedition 69 crew members are reviewing the procedures they will use when they move the SpaceX Crew Dragon spacecraft to a new port on Saturday morning. The rest of the crew aboard the International Space Station is cleaning up after completing a spacewalk earlier this week.
NASA Flight Engineers Stephen Bowen and Woody Hoburg will respectively command and pilot the Crew Dragon Endeavour spacecraft when it undocks from the Harmony module’s space-facing port at 7:10 a.m. EDT on Saturday. The pair will be flanked by UAE (United Arab Emirates) astronaut Sultan Alneyadi and Roscosmos cosmonaut Andrey Fedyaev during the planned 43-minute relocation maneuver. Endeavour, with the four crewmates inside, will automatically redock to Harmony’s forward port at 7:53 a.m. NASA TV begins it live relocation coverage at 7 a.m. on the agency’s app and website.
The quartet began Friday morning simulating their spacecraft maneuvers in coordination with mission controllers on the ground. Afterward, the foursome held a space-to-ground conference with the controllers discussing training, procedures, and mission readiness.
Endeavour’s relocation will open up Harmony’s top port for the upcoming SpaceX CRS-28 cargo mission. This enables the Canadarm2 robotic arm to reach out and access the cargo inside the SpaceX Dragon resupply ship’s trunk. Inside Dragon’s trunk will be a new set of roll-out solar arrays that the Canadarm2 will grapple and temporarily stow on the station’s starboard-side truss structure. Two astronauts on a future spacewalk will permanently install the roll-out solar arrays on the starboard truss augmenting the orbital outpost’s power generation system.
Three cosmonauts reconfigured the Roscosmos segment of the space station following Wednesday’s spacewalk to move an experiment airlock. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin deactivated and cleaned their spacesuits then stowed the tools they used during their seven-hour, 11-minute spacewalk. Fedyaev, who controlled the European robotic arm (ERA) during the spacewalk, spent Friday inside the Nauka science module removing cameras and powering down the ERA.
Prokopyev and Petelin have one more spacewalk to conduct this month when they exit the Poisk airlock on May 12 to deploy a radiator that was attached to Nauka during a previous spacewalk on April 19. Fedyaev will be inside the station monitoring the spacewalkers who will also fill the radiator with coolant and perform maintenance on the ERA.
Following extraction from Dragon, the Bigelow Expandable Activity Module (BEAM) was installed to the International Space Station at 5:36 a.m. EDT. At the time of installation, the space station was flying over the Southern Pacific Ocean. It will remain attached to station for two-year test period.
The Bigelow Expandable Activity Module, or BEAM, is attached to the International Space Station early on April 16, 2016.
NASA is investigating concepts for habitats that can keep astronauts healthy during space exploration. Expandable habitats are one such concept under consideration – they require less payload volume on the rocket than traditional rigid structures, and expand after being deployed in space to provide additional room for astronauts to live and work inside. BEAM will be the first test of such a module attached to the space station. It will allow investigators to gauge how well it performs overall, and how it protects against solar radiation, space debris and the temperature extremes of space.
In late May, BEAM will be filled with air and expanded to its full size. Astronauts will enter BEAM on an occasional basis to conduct tests to validate the module’s overall performance and the capability of expandable habitats. After the testing period is completed, BEAM will be released from the space station to eventually burn up harmlessly in the Earth’s atmosphere.
