NASA astronaut Jessica Meir and European Space Agency astronaut Sophie Adenot finished a six-hour, 49-minute spacewalk outside the International Space Station on Sept. 1, installing a new navigational aid on the Harmony module and swapping out a camera on the station’s truss. It was the fourth spacewalk outside the station in a month, NASA said, and the last currently on Expedition 75’s schedule.
Earlier in the week, President Donald Trump called the crew from Mission Control at NASA’s Johnson Space Center on Aug. 28, after awarding the Artemis II crew the Congressional Space Medal of Honor and signing an executive order creating a U.S. Space Academy, NASA said. The station crew was in the middle of spacewalk preparations at the time.
Watch: Sept. 1 spacewalk replay
NASA broadcast “U.S. Spacewalk 99,” the designation NASA uses to track spacewalks conducted in U.S. spacesuits since station assembly began, on Sept. 1. The replay below carries NASA’s full live coverage of Meir and Adenot’s excursion, recapped above.
Canadian connection
The Canadian Space Agency confirmed Sept. 2 that Joshua Kutryk’s Crew-13 flight is now targeting no earlier than late September. Kutryk is due to join NASA astronauts Jessica Watkins and Luke Delaney and Roscosmos cosmonaut Sergey Teteryatnikov for a roughly six-month stay aboard the station.
Canadarm2 also had a hand in the Sept. 1 spacewalk: NASA flight engineer Anil Menon operated the Canadian-built arm to position Meir at her worksites, while Adenot moved by tethering herself directly to the station’s exterior, NASA said in its preview of the spacewalk.
SpaceQ looked this week at what comes after the space station itself: with the ISS due for retirement by 2030, the Canadian Space Agency is weighing which of four commercial successors — Vast, Axiom Station, Starlab or Blue Origin’s Orbital Reef — might carry Canadian research forward, and Canadian robotics builder MDA Space is involved in two of them.
Science and technology experiments
Aside from the spacewalk, the crew kept up a full slate of research. Adenot logged a session on a stationary bike fitted with sensors tracking her vital signs, part of ongoing work on how long stays in microgravity affect the cardiovascular system, while Menon and Hathaway relocated science hardware around the station as part of routine maintenance.
The spacewalk itself carried a research task: Adenot and Meir began preparing the Alpha Magnetic Spectrometer, a particle detector mounted outside the station that studies cosmic rays, for a future upgrade, and the pair also swabbed the station’s exterior to sample microorganisms, NASA said. Roscosmos cosmonauts Andrey Fedyaev, Pyotr Dubrov and Anna Kikina carried out their own round of research and system checks through the week, though NASA’s recaps did not detail specific experiments.
Looking ahead
NASA and SpaceX have not set a new launch date for Crew-13, saying only that they are targeting no earlier than late September while engineers finish testing and any rework tied to the propulsion leak. Both agencies said a specific date will be announced once one is confirmed.

Executive Summary
Astronauts Jessica Meir and Sophie Adenot recently completed a nearly seven-hour spacewalk to perform critical maintenance on the International Space Station, including the installation of a navigational aid and camera replacement. This operation was part of a dense schedule of activity, marking the fourth such excursion in a single month. Parallel to these technical tasks, the crew continued scientific research on cardiovascular health in microgravity and cosmic ray detection via the Alpha Magnetic Spectrometer.
The broader operational landscape is characterized by a transition toward commercialization and upcoming crew rotations. While the International Space Station faces retirement by 2030, the Canadian Space Agency is currently evaluating several commercial successors to maintain its research presence. Meanwhile, the launch of Crew-13 remains delayed until at least late September as NASA and SpaceX address a propulsion leak. This period of activity is underscored by high-level political engagement, including the establishment of a U.S. Space Academy and honors bestowed upon the Artemis II crew.
Full Take
The strongest version of this narrative depicts a high-functioning, international partnership maintaining a legacy asset (the ISS) while simultaneously building the infrastructure for a commercial future. It highlights the seamless integration of robotic assistance, political support, and scientific rigor.
The narrative operates on a paradigm of "inevitable progression"—the transition from government-led exploration to commercial habitation. An unstated assumption is that the shift to commercial successors like Vast or Orbital Reef will maintain the same scientific and collaborative standards as the ISS. This echoes the historical pattern of privatization seen in telecommunications and aviation, where state-funded pioneers establish the frontier before handing the keys to corporate entities.
The implications suggest a shift in agency: the "who" of space research is moving from national astronauts to corporate employees or clients. While this may increase the frequency of access, it risks tethering scientific inquiry to profit margins. The primary beneficiaries are the private firms positioning themselves as the next landlords of Low Earth Orbit.
Patterns detected: none
The root cause is the looming 2030 retirement deadline, which transforms routine maintenance into a race for succession. The mention of a "propulsion leak" and "rework" for Crew-13 serves as a reminder that despite the polished narrative of progress, the physical risks of spaceflight remain the primary bottleneck.
Bridge Questions:
1. How does the transition to commercial stations change the criteria for who gets to conduct research in space?
2. If the 2030 retirement date is hard, how does the current delay in Crew-13 affect the long-term timeline for decommissioning?
3. What happens to international cooperation if commercial successors are primarily U.S.-based corporations?
Counterstrike Scan: If this were a coordinated influence campaign, the playbook would involve "sanewashing" corporate privatization by embedding commercial vendor names within reports of heroic, government-led spacewalks to create a subconscious association between state prestige and private profit. The actual content is a standard news summary and does not match this pattern.
