Sophie Adenot will make spaceflight history today (Aug. 18).
The European Space Agency (ESA) astronaut will become the first French woman ever to conduct a spacewalk, an activity she’ll undertake with NASA astronaut Anil Menon.
The duo are scheduled to step outside the International Space Station (ISS) for a 6.5-hour excursion today at around 8:35 a.m. EDT (1235 GMT). You can watch it live here at Space.com, courtesy of NASA. Coverage starts at 7 a.m. EDT (1100 GMT).
Adenot and Menon will “replace a space-to-ground antenna on the orbital complex,” NASA officials wrote in a spacewalk preview.
“The antenna is a critical communications link NASA uses to transmit data, enabling high-speed communications between the Mission Control Center in Houston and the space station,” they added.
This will be the second spacewalk for Menon; his first one, conducted with fellow NASA astronaut Jessica Meir, occurred on Aug. 6. During that extravehicular activity (EVA), a carbon dioxide sensor on Menon’s spacesuit gave “an unexpected data reading,” NASA officials wrote in an Aug. 7 update.
The sensor returned to normal after Menon doffed the suit, but NASA took some extra time to make sure there was no serious issue. As a result, the agency pushed his second spacewalk back a few days — from the originally planned Aug. 13 to today.
Today’s spacewalk will be the 282nd overall in the long history of the ISS. Menon, who reached orbit on a Russian Soyuz spacecraft on July 14, will be “crewmember 1” on the EVA. Adenot — a member of SpaceX’s Crew-12 mission, which reached the orbiting lab in February — will be “crewmember 2.”
Adenot won’t be the first French person overall to conduct an EVA. That distinction goes to Jean-Loup Chrétien, who performed a spacewalk outside the then-Soviet Union’s Mir space station in 1988.
Other male French astronauts, including Philippe Perrin and Thomas Pesquet, later spacewalked outside the ISS. Pesquet also became the first French person to command an ISS mission, taking the reins in October 2021.
