A Busy August Opening on the Space Station

Expedition 75 astronauts aboard the International Space Station opened August with spacewalk preparations and a round of health research, while NASA introduced the next crew scheduled to fly to the orbital outpost. The spacewalk is planned to begin at 8:35 a.m. EDT on Thursday, with live coverage starting at 7 a.m. on NASA+ and other platforms.

NASA commander Jessica Meir and flight engineer Anil Menon reviewed the procedures and configured tools and supplies needed to build a platform for a roll-out solar array planned for installation later this year. They were joined by flight engineers Jack Hathaway of NASA and Sophie Adenot of ESA, who also practiced installing emergency jetpacks, known as SAFER, on spacesuits. These jetpacks allow a spacewalker to maneuver back to the station if they become untethered.

Hathaway spent part of his shift in the Kibo module removing hardware from two technology studies on advanced computing and imaging, then tested the new European Enhanced Exploration Exercise Device in the Columbus module. Adenot tried the EasyMotion-2 suit, which uses electrical impulses to stimulate muscles during exercise, and worked on resistive exercise equipment. Russian cosmonauts Pyotr Dubrov and Anna Kikina wore arm, wrist and finger cuffs to track blood pressure changes in weightlessness and took a computerized hearing test. Andrey Fedyaev checked communications hardware and tested artificial intelligence tools intended to boost crew efficiency.

Separately, the four members of NASA's SpaceX Crew-13 appeared at a news conference from Johnson Space Center in Houston. Commander Jessica Watkins will lead pilot Luke Delaney of NASA and mission specialists Joshua Kutryk of CSA and Sergey Teteryatnikov of Roscosmos on a Dragon spacecraft mission targeted to launch no earlier than September 12.

What the Station Calendar and Crew Rotation Signal

Routine Science and Maintenance Keep the Mission Moving

The station's schedule this week reflects the standard mix of priorities for an Expedition crew: prepare critical hardware for an external maintenance task, keep the crew physically conditioned, and collect data on how long-duration weightlessness affects the human body. The exercise device evaluations and blood-pressure monitoring are part of ongoing efforts to understand health risks for future exploration missions beyond low Earth orbit.

Crew-13 Marks a Familiar Command Profile

Jessica Watkins returning to the station on a second Dragon flight points to NASA rotating experienced commanders into crew rotations. The rest of Crew-13 are first-time space fliers, which is typical for recent commercial crew missions. The arrival of the new crew in September will begin a handover period with Expedition 75, though the exact overlap depends on the final launch date.

International Participation Remains Central

Crew-13's lineup again shows the station's multinational character, with crew members from NASA, CSA and Roscosmos, while ESA's Sophie Adenot serves on the current expedition. The continued integration of partner agencies keeps the ISS program operating as a cooperative endeavor even as individual agencies plan their own future destinations.
