Historic Spacewalk Completed

NASA astronaut Jessica Meir and European Space Agency (ESA) astronaut Sophie Adenot completed the sixth all-female spacewalk on September 1, 2026, stepping outside the International Space Station (ISS) for six hours and 49 minutes. The two astronauts replaced a spacecraft docking aid and an HD camera, as well as carrying out maintenance and scientific tasks, according to reports from Space and The Times of India.

The spacewalk began from the S. Quest airlock at 8:40 m. EDT (1240 GMT). Meir and Adenot first replaced the planar deflector on the forward port of the station's Harmony Node 2 module. This retroreflector supports navigation during rendezvous and docking operations by visiting spacecraft. The older reflector had become coated in thruster residue from earlier spacecraft arrivals and departures.

They then replaced the Camera Port 3 (CP3) high-definition camera mounted on the station's truss. "And it's off!" Meir reported after freeing the spent camera assembly, a comment met by applause in Mission Control at NASA's Johnson Space Center in Houston.

Maintenance and Science Tasks

Following the camera replacement, Adenot continued an ongoing scientific study by swabbing areas on the exterior of the airlock and her gloves for possible microorganisms. Meir rode one end of the Canadarm2 robotic arm to a site near the Alpha Magnetic Spectrometer (AMS), torquing 46 bolts in preparation for future maintenance of the particle physics detector. She also relocated power and thermal jumper cables and an articulating portable foot restraint for use on a later spacewalk.

The AMS is a $2 billion particle physics experiment mounted to the exterior of the ISS that studies cosmic rays and hunts for dark matter, among other tasks, as noted by Space in its pre-spacewalk coverage.

Spacesuit Mobility Issue

Toward the end of the EVA, Adenot reported losing mobility in her left shoulder joint. Erring on the side of caution, Mission Control asked her to remain where she was until Meir could reach her. Once inside the airlock, Meir inspected Adenot's spacesuit and freed what appeared to be a cable caught near the shoulder joint. Meir explained: "I think it was where the cable got caught in between the shoulder MLI and the rotation [joint]. I don't think it was held up by anything but some friction."

The two astronauts completed the spacewalk at 4:29 m. EDT (2029 GMT).

Career Milestones

Tuesday's spacewalk was Meir's seventh, placing her third among female NASA astronauts for total number of spacewalks, with 49 hours and 22 minutes of spacewalking time, trailing only Peggy Whitson (10 spacewalks) and Suni Williams (nine), according to NASA statistics cited by Space and The Times of India. Adenot's third spacewalk brought her total to 19 hours and 42 minutes in the vacuum of space, as reported by Space.

Adenot two weeks earlier became the first French woman to perform an extravehicular activity, Space reported. Her path to space included aerospace engineering studies at ISAE-SUPAERO in Toulouse, a master's degree in human factors engineering from MIT, and service as a helicopter test pilot in the French Air Force, according to ESA information carried by The Times of India.

Meir's background, as detailed in NASA's official astronaut biography, included a doctorate in Marine Biology from the Scripps Institution of Oceanography, research on emperor penguins in Antarctica, and selection as an astronaut in 2013. She first flew to the ISS in 2019 and was part of the first all-female spacewalk alongside Christina Koch, The Times of India reported.
