  • Expedition 75 is Go for Tuesday Spacewalk to Install High-Speed Antenna

    ESA astronaut Sophie Adenot is pictured inside the International Space Station's Quest airlock with her helmet visor down as she nears the end of a six‑hour, 23‑minute spacewalk on Aug. 18. 2026.

    Two astronauts will exit the International Space Station on Tuesday and conduct a spacewalk to finish installing a high-speed space-to-ground antenna. The duo completed final spacewalk preparations on Monday with two of their Expedition 75 crewmates while the rest of the orbital residents studied the human respiratory system, activated Earth observation gear, and packed a cargo spacecraft prior to its departure.

  • Week Ends With Spacewalk Preps and Space Exercise Research

    ESA astronaut Sophie Adenot tries on a spacesuit to verify its comfort, mobility, and functionality inside the International Space Station's Quest.

    The Expedition 75 crew wrapped up the work week getting ready for a spacewalk to finish installing a high-speed antenna on the International Space Station. The orbital residents also explored new space exercise techniques, studied the human respiratory system, and completed an Earth observation session. On Friday, flight engineers Anil Menon of NASA and Sophie […]

  • Expedition 75 Cleans Up After Spacewalk, Keeps Up Microgravity Research

    From left, Expedition 75 flight engineers Anil Menon of NASA (partially obscured and wearing the spacesuit with a red stripe on the legs) and Sophie Adenot of ESA (European Space Agency) work together during a six‑hour and 23‑minute spacewalk outside the International Space Station. The duo disconnected a failed high‑speed antenna and secured it with a long‑duration tie‑down on the orbital outpost’s Z1 truss segment. A spare antenna will be installed on the Z1 truss during a future spacewalk.

    The Expedition 75 crew members cleaned up on Wednesday after a spacewalk that saw two astronauts uninstall an antenna outside the International Space Station. The lab residents also continued their microgravity research exploring the circulatory system, studying artificial intelligence, and photographing the Earth. Flight engineers Anil Menon of NASA and Sophie Adenot of ESA (European […]

  • NASA, ESA Astronauts Ready for Tuesday’s Antenna Swap Spacewalk

    The Expedition 75 crew has completed preparations and mission managers are go for a spacewalk to swap out a high-speed antenna outside the International Space Station on Tuesday. Meanwhile, there was still time on Monday’s research schedule for cardiac research, artificial intelligence tests, and Earth observations.

  • Week Ends Aboard Station With Robotics, Spacewalk Reviews, and Science

    Expedition 74 flight engineers Sophie Adenot of ESA (European Space Agency) and Jessica Meir of NASA work together inside the International Space Station’s Quest airlock. Adenot is wearing a spacesuit in a powered and pressurized configuration to test its mobility, comfort, and optimal fit. Meir also assisted Adenot in conducting suit leak and pressure checks while verifying the suit’s communications hardware and life‑support systems.

    Expedition 75 ended the week studying Canadarm2 robotic arm maneuvers and reviewing procedures for a spacewalk to support the removal and replacement of a space-to-ground antenna on Tuesday, Aug. 18. Science remained on Friday’s schedule as the International Space Station residents studied space exercise techniques, explored aerodynamic drag forces, and more.

  • Thursday Packed with More Spacewalk Preps and Advanced Tech Research

    Expedition 75 flight engineer Jack Hathaway assists Expedition 75 flight engineer Anil Menon, both NASA astronauts, inside the Quest airlock as he tried on a spacesuit to verify its comfort, mobility, and functionality. Menon was conducting an on-orbit fit verification of the suit before conducting his first spacewalk outside of the International Space Station.

    The Expedition 75 crew continued studying procedures and checking out spacesuits on Thursday for a spacewalk to replace a high-speed antenna on the outside of the International Space Station next week. High-tech science rounded out the schedule as the lab residents wore virtual reality goggles and tested artificial intelligence tools to benefit future space crews.
