Russian Cosmonauts Complete 6-Hour ISS Spacewalk

Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev concluded a spacewalk outside the International Space Station at 4:23 p.m. EDT on Wednesday, completing a range of scientific tasks over 6 hours and 5 minutes, according to NASA.nasa

The outing exceeded its originally planned duration of roughly five hours, as the pair worked through a list of objectives that included installing new hardware and retrieving completed experiments from the station’s Russian segment.spaceanddefense

Solar Radiation Instrument Installed

The cosmonauts installed a device on the Zvezda service module designed to measure bursts of solar radiation from solar flares, NASA reported. They also removed a microorganism study from the exterior of the Poisk module and retrieved a cassette from the Nauka module containing data on how semiconductor materials form in microgravity.nasa

Antenna Inspection on Cargo Craft

During the spacewalk, Kud-Sverchkov and Mikaev photographed one of two Kurs rendezvous antennas on the Progress 94 cargo spacecraft that failed to deploy following its March launch to the station. After collecting imagery, they secured the antenna with a tie-down for future dynamic operations.nasa

Career Milestones

The excursion marked the second spacewalk for Kud-Sverchkov, who has now logged 12 hours and 11 minutes of extravehicular activity, and the first for Mikaev. It was the 279th spacewalk in support of space station assembly, maintenance, and upgrades since construction began in 1998.nasa

The spacewalk was part of the station’s ongoing Expedition 74, with Kud-Sverchkov serving as commander and Mikaev as flight engineer. NASA provided live coverage of the event beginning at 9:45 a.m. EDT.youtube
