A Russian cosmonaut took a brief journey on the finish of a robotic arm to jettison spent tools that he and a crewmate collected throughout a spacewalk exterior the Worldwide House Station right now (Dec. 19).
Expedition 72 flight engineer Alexey Ovchinin secured his toes at one finish of the European Robotic Arm (ERA) towards the tip of his and Ivan Vagner’s seven-hour extravehicular exercise (EVA) right now. Fellow Roscosmos cosmonaut Alexsandr Gorbunov managed the 37-foot-long (11.3 meters) arm’s motion from contained in the house station.
On the desired level, Ovchinin tossed the bundle of not wanted electrical connectors, covers and an experiment increase overboard such that it could not are available contact with the orbiting laboratory earlier than burning up whereas reentering Earth’s environment.
“Right here it goes, it’s floating away,” stated Ovchinin as he launched the bundle with a push towards the aft finish of the house station. “It’s going away properly.”

Ovchinin and Vagner started the spacewalk at 10:36 a.m. EST (1536 GMT) as they opened the hatch to the airlock on the Poisk mini-research module. As soon as exterior the station and having picked up the instruments they wanted for the tour, the 2 cosmonauts proceeded to the Zvezda service module, the place they put in the “All-Sky Monitor,” an X-ray spectrometer.
Utilizing the All-Sky Monitor, “scientists will conduct a periodic, nearly full (84 p.c) statement of the celestial sphere inside the X-ray wavelength vary each 72 days over three years (in all, 15 such observations are being deliberate),” in accordance with a Roscosmos assertion.
From there, Ovchinin and Vagner labored on swapping out 4 electrical connector patch panels on the surface of Zvezda with new replacements. The previous panels had been a part of the bundle that Ovchinin disposed of later within the spacewalk.
The cosmonauts additionally collected experiments that uncovered supplies (“Take a look at and Endurance”) and organic samples (“Management”) to evaluate their response to the house setting. Ovchinin and Vagner introduced the experiment panels again contained in the station to be returned to Earth on a Soyuz spacecraft for additional examine on the bottom.
As a remaining job, the spacewalkers jettisoned towels that they used to wipe down their spacesuits’ gloves earlier than reentering the airlock.
As a consequence of time constraints, the spacewalkers forewent the relocation of an exterior management panel for the European Robotic Arm. The transfer would have cleared a translation path for future EVAs however in any other case was not crucial to station operations.
Thursday’s spacewalk ended at 5:53 p.m. (2253 GMT), 7 hours and 17 minutes after it started. It was the 272nd EVA in help of the meeting, upkeep and improve of the Worldwide House Station since 1998.
This was the primary spacewalk throughout Expedition 72 and the third carried out on the Worldwide House Station this 12 months (together with a U.S. spacewalk that was lower brief at simply 31 minutes as a consequence of a water leak whereas each crew members had been nonetheless contained in the Quest airlock). 5 extra spacewalks had been carried out in 2024, together with 4 exterior China’s Tiangong house station by the Shenzhou 17, 18 and 19 crews and the world’s first business spacewalk, carried out by the Polars Daybreak crew exterior a SpaceX Dragon spacecraft.
It was Ovchinin’s second EVA and Vagner’s first. Ovchinin beforehand carried out a six hour and one minute spacewalk in 2019, such that his whole is now 13 hours and 18 minutes working within the vacuum of house.
