Summary

  • Progress MS-35 lifted off from Baikonur on Sept. 16 after a technical problem delayed the Russian cargo mission by a week from its original Sept. 9 launch date.
  • More than 2,400 kilograms of cargo is headed to Expedition 75, including 275 kilograms of food, 842 kilograms of propellant, 420 kilograms of water and 50 kilograms of oxygen.
  • The spacecraft entered orbit about 554 seconds after liftoff and is following a three-day, 45-orbit rendezvous for automated docking at the Poisk module on Sept. 19.
  • The mission also marks a switch in Russian cargo launches from the Soyuz-2-1a to the Soyuz-2-1b rocket variant, part of a broader Soyuz fleet consolidation.
  • If the mission proceeds as planned, Progress MS-35 will remain at the station until February 2027 before undocking for destructive reentry.
