Indian-origin astronaut Anil Menon set for second spacewalk to replace ISS antenna

Mark
Why does the ISS need to replace this antenna right now? Is it urgent, or is this just scheduled maintenance?
Mimi
The antenna has already failed, so it's not preventive—it's a repair that needs to happen. Without it, the station loses a critical link to Mission Control in Houston. That's not something you can leave broken for long.
Luke
The source says the antenna is "failed," but it doesn't explain what that failure looks like operationally. Can the station still communicate without it, or is it completely dark? That matters.
Mark
Two spacewalks in two weeks seems intense. Is that normal?
Mimi
It's not routine, but it's not unheard of either. The station has a lot of systems that need maintenance, and sometimes the work stacks up. Menon and Adenot have been training for this, so NASA wouldn't send them out if they weren't ready.
Luke
The source doesn't tell us whether this back-to-back schedule was planned months ago or if the antenna failure forced them to accelerate things. That's a real operational question.
Mark
What makes Sophie Adenot's spacewalk historically significant?
Mimi
She's the first French woman to do this. France has had astronauts in space before, but never a woman conducting a spacewalk. It's a milestone for the European Space Agency and for France specifically.
Luke
That's accurate, but we should note the source doesn't provide context on how many French astronauts have done spacewalks total, or what the broader gender breakdown looks like in EVA history. It's a real achievement, but we're working with limited historical framing.
Mark
How dangerous is a spacewalk?
Mimi
It's one of the most dangerous things an astronaut does. You're in a vacuum with only a suit and a tether between you and the void. But the procedures are rigorous, the training is extensive, and the safety systems are redundant.
Luke
The source doesn't quantify risk or mention any incidents or near-misses. We know spacewalks happen regularly and people train for them, but the source doesn't actually tell us how often things go wrong or what the safety record looks like.
The Pulse
- A failed Space-to-Ground antenna has severed a vital data artery between the ISS and Mission Control in Houston, making the August 18 repair not a routine upgrade but an urgent restoration.
- Menon and Adenot will spend six and a half hours exposed to the vacuum of space — tethered, suited, and navigating the station's exterior with no margin for error.
- The operation demands precise choreography: removing the failed unit, securing it externally, and installing a spare on the Z1 truss, all while two astronauts inside manage suits and the Canadarm2 robotic arm.
- Menon is completing his second spacewalk in under two weeks, following a six-hour August 6 EVA that restructured the station's power infrastructure for future solar expansion.
- Sophie Adenot's first-ever spacewalk will simultaneously mark a milestone for France and for ESA's deepening role in sustaining the orbiting laboratory.
High above the Earth, where silence and vacuum press against the thin shell of human ingenuity, Indian-origin NASA astronaut Anil Menon and ESA astronaut Sophie Adenot prepare to step outside the International Space Station on August 18 to restore a critical communications link with Mission Control. In less than two weeks, Menon will have completed two spacewalks — a pace that reflects both the fragility and the relentless upkeep demanded by humanity's most ambitious shared outpost. For Adenot, the moment carries its own quiet history: she will become the first French woman ever to walk in open space, adding her name to the long lineage of those who have ventured beyond the hull in service of collective knowledge.
On August 18, Anil Menon will step outside the International Space Station for the second time in less than two weeks. Alongside ESA astronaut Sophie Adenot, he will spend six and a half hours in open space replacing a failed communications antenna — the hardware that allows the ISS to exchange high-speed data with Mission Control in Houston. NASA's live coverage begins at 4:30 pm IST, with the spacewalk itself commencing around 6:05 pm.
The task is precise and demanding. The two astronauts will remove the failed Space-to-Ground antenna, secure it on an external platform, and install a replacement unit on the station's Z1 truss — all while wearing suits that function as miniature spacecraft, managing oxygen, pressure, and temperature in the hostile environment beyond the hull. Inside the station, astronauts Jack Hathaway and Jessica Meir will assist with suit operations, and Hathaway will operate the Canadarm2 robotic arm throughout the procedure.
Menon's first spacewalk came on August 6, when he and Meir spent over six hours outside preparing the station's 3B power channel to support a future solar array — the 281st EVA in the history of ISS assembly and maintenance. That he returns to the exterior so quickly speaks to both his readiness and the operational demands of keeping the station running.
For Sophie Adenot, August 18 carries a different kind of weight. It will be her first spacewalk — a defining moment in any astronaut's career — and it will make her the first French woman ever to conduct an EVA. Her participation is a quiet but meaningful marker of how broadly the international partnership of the ISS has grown, and how central ESA has become to the work of sustaining it.
Anil Menon is about to step outside the International Space Station for the second time in less than two weeks. On August 18, the Indian-origin astronaut and European Space Agency colleague Sophie Adenot will venture into the vacuum of space to replace a communications antenna that has failed—a piece of hardware critical to the station's ability to send and receive data with Mission Control in Houston. The operation is scheduled to last six and a half hours, with NASA's live coverage beginning at 4:30 pm Indian Standard Time and the spacewalk itself starting around 6:05 pm IST.
A spacewalk, formally known as an Extra Vehicular Activity or EVA, is among the most demanding tasks an astronaut can perform. Once outside the station, Menon and Adenot will wear specialized spacesuits that function as miniature spacecraft, supplying oxygen, maintaining pressure, managing temperature, and shielding them from the hostile environment beyond the hull. They will remain tethered to the station at all times and use handrails to navigate the exterior surfaces. The suits allow astronauts to accomplish repairs, install equipment, and upgrade the orbiting laboratory without ever bringing hardware back to Earth.
The specific task ahead involves removing the failed Space-to-Ground antenna from its current location, securing it on an external platform, and installing a spare unit on the station's Z1 truss. This antenna serves as a vital communications link, enabling the ISS to exchange high-speed data with Mission Control. Menon and Adenot have spent considerable time preparing for this work—rehearsing procedures, inspecting their spacesuits, and practicing the movements and techniques they will need to execute outside the station. Two other NASA astronauts, Jack Hathaway and Jessica Meir, will assist them from inside, helping them don and remove their suits. Hathaway will also operate the station's Canadarm2 robotic arm during the operation.
This mission comes remarkably soon after Menon's first spacewalk on August 6, when he and Meir spent six hours and twenty-seven minutes outside the ISS working on the station's 3B power channel. That operation prepared the infrastructure to support a future roll-out solar array, part of a broader effort to expand the station's power supply. The August 6 spacewalk marked the 281st EVA conducted in support of ISS assembly, maintenance, and upgrades since the station's construction began.
The August 18 mission carries additional significance beyond the antenna replacement. For Sophie Adenot, this will be her first spacewalk—a milestone in any astronaut's career. More broadly, her participation makes her the first French woman ever to conduct a spacewalk, a distinction that underscores the international character of the ISS and the expanding role of European Space Agency personnel in maintaining the orbiting laboratory. Menon, by contrast, will be adding a second spacewalk to his record in the span of twelve days, a demanding schedule that speaks to both his preparation and the operational tempo required to keep the station functioning at peak capacity.
