The Sixth All-Female Spacewalk: Progress or Pattern?
Jessica Meir and Sophie Adenot completed the sixth all-female spacewalk on Sept. 1. Nadia Marchetti asks what six really tells us about space exploration.
Written by AI. Nadia Marchetti
Six all-female spacewalks across more than two decades of continuous human occupation of the International Space Station. I keep turning that number over. The ISS has hosted crews since November 2000. Hundreds of spacewalks have gone out from that airlock. Six of them, in all that time, have been conducted by two women.
On September 1, NASA astronaut Jessica Meir and European Space Agency astronaut Sophie Adenot stepped outside the ISS at approximately 8:35 a.m. ET for a maintenance excursion expected to last around 6.5 hours, according to Fox 35 Orlando. NASA's official release framed the excursion around its operational purpose: replacing a component and completing standard upkeep on the station's exterior. The BBC's coverage noted the walk lasted approximately 6.5 hours. Yahoo News and Space.com flagged the historic dimension: sixth-ever all-female spacewalk, live coverage available.
Both framings are correct. The tension between them is the actual story.
What Jessica Meir Has Already Proven
Meir's name on this mission is not coincidental. According to Fox 35 Orlando, the first all-female spacewalk was conducted by Meir and Christina Koch in October 2019. That one had its own backstory: NASA had originally scheduled an all-female walk earlier that year but had to reshuffle the crew assignment because only one medium-sized spacesuit was available on the station at the time. The agency drew criticism. It reconfigured. Koch and Meir went out a few months later.
Meir returning to anchor the sixth all-female spacewalk says something about crew selection, ISS rotation schedules, and the specific demands of EVA-qualified astronauts. It also means there is exactly one person who has now participated in both the first and the sixth. That is a strange continuity.
The spacesuit situation in 2019 was fixed through logistics, not ideology. NASA added suit sizes to the station's inventory. The result was that the seventh and eighth and subsequent all-female walks became structurally possible in a way they had not been before. That is the change worth tracing: not the rhetoric around inclusion, but the moment when a hardware constraint stopped being an excuse.
Sophie Adenot and the Question of Pipeline
Adenot brings a different angle to this. She is a French military helicopter test pilot selected as part of a recent ESA astronaut class, according to Space.com. Her presence on this walk, on what appears to be her first long-duration mission, reflects a shift in who is entering the astronaut pipeline at all.
For decades, the under-representation of women in spacewalks was partly a reflection of under-representation in the applicant pool, which was itself a reflection of barriers in the military aviation and engineering fields that fed into astronaut selection. Those barriers have not vanished. But they have moved. Adenot coming through a European selection process as a test pilot and arriving at the ISS mission-ready is downstream of decades of incremental change in those feeder fields.
This is where I find the story complicated. The sixth all-female spacewalk is, in one sense, an indicator that the pipeline is producing differently than it did in 1983 when Sally Ride flew, or in 2019 when NASA had to scramble over a suit size. But six across twenty-plus years is still a low count if the goal is normalization. Progress in the pipeline has been real and slow simultaneously.
The Accidental Architecture of Milestone Six
Here is what bothers the correspondent in me: this walk probably did not get scheduled because someone at NASA or ESA decided the time had come for all-female spacewalk number six. It got scheduled because Meir and Adenot were the two astronauts on the current rotation with the right EVA certifications, the right suit sizes, and the right task assignments for this maintenance excursion. The milestone is a byproduct.
I find that both reassuring and insufficient. Reassuring because it suggests the crew composition is being driven by operational competence rather than optics. Insufficient because if the seventh all-female spacewalk also happens accidentally, as a scheduling outcome rather than a structural norm, then the number will keep creeping upward at this pace: six in twenty-five years, maybe nine in thirty-five.
What would a non-accidental architecture look like? It would look like a station where EVA-qualified women are consistently present in numbers that make all-female walks unremarkable rather than countable. We are not there. We are closer than we were in 2019. The distance remaining is not measured in press releases; it is measured in selection rates, certification pipelines, and who gets assigned the tasks that build EVA experience in the first place.
What They Actually Did Out There
Before I get too far into the meta-question, the work itself deserves a moment. Maintenance spacewalks are not glamorous. They are six-plus hours of careful, exhausting labor conducted in pressurized suits while traveling at orbital velocity above Earth's atmosphere, with no margin for the kind of errors that are merely inconvenient on the ground. NASA's release confirmed the walk was planned for component replacement and general station upkeep.
The ISS has been continuously occupied for more than two decades. Its exterior is a working structure that requires regular human intervention to stay functional. Every spacewalk that completes its maintenance objectives is a small argument for keeping humans in the loop on orbital infrastructure, at a time when the future of the ISS post-2030 is actively being debated. Meir and Adenot spending 6.5 hours ensuring the station keeps running is a concrete contribution to that debate, whether or not anyone frames it that way.
The Pairing That Makes This Walk Specific
What I keep returning to is the particular combination of Meir and Adenot. Meir is American, a NASA veteran who has been part of this story since its first chapter. Adenot is French, ESA-selected, newer to orbital missions. They planned, communicated, and executed a complex extravehicular task together, coordinating across two agencies whose training systems, bureaucratic cultures, and operational languages are not identical.
That kind of cross-agency fluency does not happen automatically. It requires translation, literally and procedurally, of the sort that tends to be invisible when it goes well. The fact that it went well is the data point. The ISS has always been an argument that rival space programs can share an airlock. Meir and Adenot are that argument's latest iteration.
Six is a strange number. Not small enough to be a scandal, not large enough to be a norm. If the conditions that produced this walk, a specific crew rotation, matching suit sizes, aligned task requirements, keep being the mechanism that produces all-female walks, then number seven will arrive the same way number six did: as a pleasant accident dressed up as a milestone.
I would like to be wrong about that. The case for being wrong is Sophie Adenot: she came through a pipeline that has more women in it than the pipeline that produced the 2019 crew. If that trend continues, the accidental architecture eventually becomes structural. The question is whether anyone is counting the pipeline, not just the walks.
