On 18 August, ESA astronaut @Soph_astro will take her first spacewalk. A remarkable moment for Sophie, for @esa, and for all those who believe that space exploration is an undeniable part of our future.
The @Space_Station has shown what Europe can achieve when we invest in human exploration and work with international partners. But the Station is not the final destination. It is part of the journey.

Our next great horizon is the Moon. And eventually Mars.

As Sophie steps outside, let us celebrate not only her milestone, but the future it foreshadows.

From low Earth orbit to the Moon and beyond, Europe should not simply watch the next chapter of human exploration unfold. We should help write it.

"Toute activité dans l'espace est un danger" : pourquoi l'astronaute française Sophie Adenot va prendre de tels risques en dehors de l'ISS
Benjamin Pierret publié le 18/ 08/2026 à 10:46

Sophie Adenot assure ce mardi 18 août une mission extravéhiculaire sur l'ISS. L'astronaute française doit mener à bien une opération de réparation qui n'est pas sans risques.

Il sera 14h35 précises, cet après-midi, quand l'astronaute française Sophia Adenot va quitter la Station spatiale internationale pour 6h30 de face à face avec le cosmos, à 400 km de la Terre. Elle deviendra la première française a effectuer une sortie extravéhiculaire en scaphandre dans l'espace, dans le cadre de cette mission qui n'a rien d'un exercice de tourisme : la scientifique de 44 ans va assurer une opération de maintenance.

"Il y a une antenne de liaison qui est en panne et qui doit être remplacée" sur l'ISS, explique sur RTL Lionel Suchet, directeur général du Centre national d'études spatiales. "C'est pour remplacer des éléments qui sont usés ou qui sont abîmés qu'on fait ces sorties, et c'est ce que va faire Sophie aujourd'hui en remplaçant une antenne de transmission entre la station et le sol."

Car comme toute machine, la Station spatiale internationale a besoin d'entretien : "Il y a des choses qui tombent en panne et de temps en temps, il faut réparer. Quand c'est à l'intérieur, évidemment, c'est plus facile. Mais quand il y a des éléments qui ne sont pas accessibles de l'intérieur, il faut faire ces sorties." Une autre est d'ailleurs prévue dans une semaine, cette fois pour faire de la "maintenance préventive".

"On a à changer des câbles, des connecteurs de façon régulière. Ça, c'est prévu. Et puis parfois il y a des choses qui tombent en panne, il faut sortir et c'est moins prévu. Et on se prépare au sol à répondre à ces besoins pour maintenir la station en permanence en bon état de fonctionnement."

"Un moment de sidération pendant quelques secondes"

Une préparation physique mais également mentale. Car se retrouver face à l'immensité du cosmos n'a rien d'anodin. "Vous vous retrouvez dans une ambiance que vous n'avez jamais vécue (...) Quand vous ouvrez le sas de sortie, vous vous retrouvez vraiment en flottaison libre à l'extérieur de la station, c'est un moment tout à fait particulier et beaucoup d'astronautes vivent un moment de sidération pendant quelques secondes. Il faut vraiment une force psychologique pour se remettre au travail dans cette situation, pour revenir à la réalité, si on peut dire, pour se mettre au travail, tellement le moment est exceptionnel quand vous ouvrez la porte du sas qui ouvre vers l'extérieur de la station."

D'autant que l'exercice n'est pas sans risques : "Toute activité dans l'espace est un danger", rappelle le spécialiste. "Un scaphandre, c'est un vaisseau spatial à part entière ; il peut tomber en panne, il peut y avoir des problèmes dans le scaphandre, c'est déjà arrivé. On peut recevoir un micrométéorite qui fait une dépressurisation du scaphandre, c'est possible. Tout peut arriver, et c'est pourquoi toutes les procédures sont prêtes pour rentrer rapidement dans le sas, repressuriser, revenir vers la station."

En outre, les sorties se font toujours à deux : "Il y a toujours deux astronautes qui sont à l'extérieur, qui sont suivis par d'autres astronautes à l'intérieur de la station en permanence et depuis le sol, bien évidemment. Donc, tout est prêt pour répondre à un problème." Lors de cette sortie, Sophie Adenot sera accompagnée par l'astronaute américain Anil Menon.

Stubborn bolts, a #DIY battle even in space 🔩
Spacewalkers @Soph_astro and @astro_anil worked out together their own bolt trick: taking turns for a few extra twists each.
Four bolts need to come out to remove a failed space-to-ground comms antenna outside the International @Space_Station 📡

Glove heaters ON for @Soph_astro🧤
It's cold out there. During a spacewalk, astronauts experience extreme temperature swings, from 120°C down to -150°C. Every spacesuit is like a small spacecraft in itself, with its own heaters and life support system.
🤔 Did you know that gloves for a spacewalk come in 63 sizes?

During today’s spacewalk, Sophie Adenot and Anil Menon successfully removed a failed communications antenna.
Removing the electrical connectors and loosening bolts took longer than expected, leaving no time to install the spare.

Record unlocked!
Congratulations to ESA astronaut Sophie Adenot on her first spacewalk yesterday - the first French woman to perform an EVA!

Spacewalks are among the most demanding activities in human spaceflight, requiring technical excellence, teamwork and months of preparation.

As Europe looks to the future of exploration, achievements like this remind us why we must continue building the capabilities that allow us not only to participate in exploration, but to help shape it.

✅ Released 📡
The spare communications antenna is free from its storage platform and on its way to the @Space_Station's Z1 truss, where @Soph_astro and @astro_anil will install it.
Stubborn bolts and connectors helped delay last week's spacewalk activities. Today, they seem much more cooperative. 😉

After a long translation along the Station's structure, Sophie caught up with Anil at the external stowage platform. Anil was transported there, along with the failed antenna, by the Canadarm2 robotic arm. They've worked together to secure the failed antenna and are now ready for clean up activities!
And great news: the newly installed antenna has good power and data – smiles and joy from everyone!

Spacewalk complete ✅
After six and a half hours outside the International Space Station, our astronaut Sophie Adenot is safely back inside.
With today's EVA, Sophie completes her second spacewalk alongside NASA astronaut Anil Menon, helping to advance the station's ongoing maintenance.
A true demonstration of teamwork in orbit.

Second spacewalk completed for Sophie Adenot
26/08/2026

(...) They first retrieved a foot restraint and installed it on Canadarm2, which was operated from inside the Station by NASA astronaut Jack Hathaway.

Anil then rode the robotic arm to External Platform 3, where the spare antenna had been stored since 2009. Sophie made her way there independently, translating along the Station's exterior.

After removing the bolts securing the antenna in place, Anil held it securely while Canadarm2 backed away from the platform and transported him, antenna in hand, to the Z1 truss. At the same time, Sophie retraced her route and translated to Z1 under her own power.

Once there, Sophie cleaned and lubricated the bolt inserts in preparation for the installation. After the spare antenna was mounted on the boom, the duo secured it and completed the electrical connections. They then removed the gimbal locks that had prevented the antenna from rotating during transport and installed a heat shield.

Next, they moved to retrieve the failed antenna that had been temporarily secured to the Station's truss during the previous spacewalk. After Sophie released the tie-downs, Anil took control of the antenna and rode the Canadarm2 to its stowage location, while Sophie translated there independently. Once at the worksite, they worked together to secure the failed antenna permanently.

Sophie then helped Anil detach from the portable foot restraint on Canadarm2, which had carried him for much of the spacewalk. Afterwards, both astronauts translated back to the airlock and ingressed the Station.

Sophie has now accumulated 12 hours and 53 minutes of spacewalking time over two EVAs. This was the 283rd spacewalk in support of space station assembly, maintenance, and upgrades.
