The crew of the International Space Station carried out a routine joint spacewalk. NASA astronaut Anil Menon and European Space Agency (ESA) representative Sophie Adenot left the station through the Quest airlock of the ISS American segment. According to the initial reports, the work began at 08:29 US Eastern Time, and the total duration of the spacewalk was about six and a half hours. After completing the operations, the astronauts safely returned to the airlock module, confirming the nominal nature of the mission. ### Exit through the Quest Airlock and Work Timing The Quest airlock is traditionally used for spacewalks by the American and international crews of the ISS. It was through this airlock that Menon and Adenot went outside the station, anchoring themselves to the external structures and equipment. A duration of about 6.5 hours corresponds to the standard procedure for comprehensive assembly and repair operations in open space, where astronauts are subject to limitations on suit operating time and life support system resource consumption. ### Mission Objectives: Upgrading Communication Systems The main objective of the spacewalk was stated to be the replacement of outdated antenna equipment that provides the station's communication with Earth and data transmission between the ISS and the ground control center in Houston. Servicing and upgrading such antenna units are critically important for stable telemetry, video communication, and station control. During the work, the astronauts performed a series of technical operations on the station's external perimeter, including work with communication equipment and mounting nodes. ### The 282nd Spacewalk in the ISS Program According to the provided data, this mission was the 282nd spacewalk in the long-term program of assembling, servicing, and upgrading the International Space Station. Each such operation accumulates experience in operating equipment under vacuum, temperature fluctuations, and radiation load, which directly affects the station's safety and service life. ### Conflicting Data There is a significant discrepancy between sources in assessing the outcome of the mission. The initial text states that the main objective of the spacewalk was precisely the *replacement* of outdated antenna equipment. However, a number of other publications indicate a different outcome: according to RFI, Adenot and Menon managed only to *dismantle* the old communication antenna during this spacewalk, while according to 24tv — the crew removed the faulty antenna but *did not manage to install* the new one. Thus, one version describes the mission as a completed replacement, while the other — as a partial fulfillment of tasks with the installation of the new antenna postponed to a future spacewalk. This is a typical mismatch that arises when aggregators publish materials at the moment of the start or end of an EVA, while some secondary operations are postponed due to suit time regulations. ### Technical Details and Significance for Future Operations Regardless of whether the new antenna was installed during this spacewalk or the installation was postponed to the next one, the very fact of conducting a routine EVA and the safe return of the crew confirms the operability of the station's systems and the crew's readiness to continue servicing. The question of installing the new antenna unit, judging by the discrepancies in the sources, may require an additional spacewalk, which will be clarified in the official NASA and ESA reports following the mission. ## 🔍 Fact-Check Verification - [NASA and ESA Astronauts Conduct Spacewalk from the ISS – Zamin.uz, 18.08.2026](https://zamin.uz/ru/tekhnologii/218440-astronavty-nasa-i-esa-vyshli-v-otkrytyy-kosmos-s-borta-mks.html) - Подтверждает факт совместного выхода Менона (NASA) и Адено (ESA) с борта МКС, дату 18.08.2026. - [Adenot and Menon Managed Only to Dismantle the Old Communication Antenna Outside the ISS](https://www.rfi.fr/ru/%D0%B2-%D0%BC%D0%B8%D1%80%D0%B5/20260818-%D0%B0%D0%B4%D0%B5%D0%BD%D0%BE-%D0%B8-%D0%BC%D0%B5%D0%BD%D0%BE%D0%BD-%D1%83%D1%81%D0%BF%D0%B5%D0%BB%D0%B8-%D1%82%D0%BE%D0%BB%D1%8C%D0%BA%D0%BE-%D0%B4%D0%B5%D0%BC%D0%BE%D0%BD%D1%82%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D1%82%D1%8C-%D1%81%D1%82%D0%B0%D1%80%D1%83%D1%8E-%D0%B0%D0%BD%D1%82%D0%B5%D0%BD%D0%BD%D1%83-%D1%81%D0%B2%D1%8F%D0%B7%D0%B8-%D0%B7%D0%B0-%D0%B1%D0%BE%D1%80%D1%82%D0%BE%D0%BC-%D0%BC%D0%BA%D1%81) - Указывает, что в ходе выхода была демонтирована только старая антенна; новая не установлена — расхождение с версией о полной замене. - [ISS Crew Went on a Spacewalk to Remove a Faulty Antenna but Did Not Manage to Install a New One](https://24tv.ua/tech/ru/mezhdunarodnaja-kosmicheskaja-stancija-tak-i-ne-poluchila-novuju-antennu-remont-zaderzhivaetsja_n3126299) - Подтверждает демонтаж неисправной антенны и перенос установки новой; согласуется с версией RFI. - [US and French Astronauts Complete Spacewalk from the ISS](https://news.rambler.ru/tech/56927669-astronavty-ssha-i-frantsii-zavershili-vyhod-v-otkrytyy-kosmos-s-borta-mks/) - Подтверждает завершение выхода и возвращение экипажа на борт станции. ## ❓ FAQ ### Q: Who conducted the spacewalk from the ISS? **A:** The spacewalk was conducted by NASA astronaut Anil Menon and European Space Agency (ESA) representative Sophie Adenot through the Quest airlock of the station's American segment. ### Q: What was the purpose of this spacewalk? **A:** The main objective was servicing and upgrading the antenna equipment that provides the station's communication with Earth and data transmission to the control center in Houston. ### Q: How long did the spacewalk last and when did it begin? **A:** According to the provided data, the work began at 08:29 US Eastern Time and lasted about six and a half hours. ### Q: Was the new antenna installed during this spacewalk? **A:** Sources disagree: some claim the equipment was replaced, however RFI and 24tv report that only the old antenna was dismantled during the spacewalk, and the installation of the new one was not completed and may be postponed to a future spacewalk. ### Q: Which number is this spacewalk in the ISS program? **A:** According to the provided data, this mission was the 282nd spacewalk in the assembly, servicing, and upgrading of the International Space Station.
