NASA astronauts Jack Hathaway, Jessica Meir, and Anil Menon will observe Labor Day on September 7 while aboard the International Space Station (ISS), according to a NASA report from September 4. European Space Agency astronaut Sophie Adenot, who recently made history as the first French woman to perform a spacewalk, will also be off duty on the same day. In contrast, the three Russian cosmonauts aboard the ISS—Pyotr Dubrov, Andrey Fedyaev, and Anna Kikina—will remain on duty, continuing their work in space. The Russian cosmonauts will be responsible for monitoring the undocking of the Progress 94 resupply spacecraft from the Poisk module on Monday. This spacecraft will carry trash and outdated equipment back to Earth. It will be replaced by the Progress 96 resupply spacecraft, which is set to launch from Kazakhstan's Baikonur Cosmodrome on September 9. The Progress 96 will then automatically dock with the Poisk module two days later, ensuring the ISS continues to receive necessary supplies. NASA astronauts Hathaway, Meir, Adenot, and Fedyaev arrived at the ISS in mid-February as part of SpaceX's Crew-12 mission. Dubrov, Kikina, and Menon are newer crew members who reached the station aboard a Russian Soyuz spacecraft on July 14. The ISS crew typically includes astronauts and cosmonauts from multiple countries, each with their own schedules and traditions. Astronauts on long-duration missions to the ISS usually have weekends and major holidays off, as this downtime is essential for their well-being and productivity. However, their celebrations differ from those on Earth. For instance, open flames are prohibited on the ISS, so astronauts will not be grilling food on Labor Day. Despite these differences, international crew members often try to celebrate major holidays like Christmas together. This shared tradition helps build camaraderie and offers emotional support for being far from home.
