PROGRESS-MS 34

Russian Cargo Spacecraft (ISS Resupply & Reboost) · Roscosmos / RKTs Progress

Progress MS-34 launched April 25, 2026 — the second Progress mission to fly from Baikonur's Site 31/6 since it was repaired following the Soyuz MS-28 launch accident that wrecked the pad the previous November. Unlike its sibling Progress MS-33, which docked to the less favorably positioned Poisk module, MS-34 docked to Zvezda's aft port, where it can actually fire its engines to reboost the ISS's orbit and keep the station from gradually sinking back toward the atmosphere — a job the other docked Progress simply isn't positioned to do. It's scheduled to remain docked for roughly seven months before being filled with the station's trash and sent to burn up over the ocean.
