Expedition 75 was preparing the International Space Station for the planned arrival of NASA's SpaceX Crew-13 mission, scheduled to launch and dock on Thursday, Oct. 1, according to a NASA space station report published Sept. 30, 2026. The report said commander Jessica Watkins and pilot Luke Delaney, both NASA astronauts, along with mission specialists Joshua Kutryk of the Canadian Space Agency and Sergey Teteryatnikov of Roscosmos, were set to launch atop a Falcon 9 from Cape Canaveral Space Force Station's Launch Pad 40 in Florida, with docking planned at the Harmony module's forward port.

On Wednesday, Sept. 30, the report said, station commander Jessica Meir reorganized cargo in Harmony's pressurized mating adapter-2 to make room for the arriving crew, and flight engineers Anil Menon and Jack Hathaway staged supplies in Harmony for use after the four enter the station.

The report also described research that day: ESA flight engineer Sophie Adenot exercised on the European Enhanced Exploration Exercise Device and practiced simulated lunar landing techniques on a computer, Roscosmos flight engineer Andrey Fedyaev continued testing a lower body negative pressure suit, and cosmonauts Anna Kikina and Pyotr Dubrov took turns using arm, wrist and finger cuffs to measure blood pressure. Kikina later unloaded cargo from the Progress 96 spacecraft while Dubrov worked on life support and computer maintenance.
