Progress MS-29 (Russian: Прогресс МC-29), Russian production No. 459, identified by NASA as Progress 90, was a Progress spaceflight launched by Roscosmos to resupply the International Space Station (ISS). It is the 182nd flight of a Progress spacecraft.
Progress MS-29, launched on 21 November 2024 at 12:22:23 UTC (17:22:23 AQTT, local time at the launch site)[2] from Site 31/6 at the Baikonur Cosmodrome in Kazakhstan atop a Soyuz-2.1a rocket. After a nominal two-day free flight, it docked with the zenith (space facing) port of the ISS's Poisk module on 23 November at 14:31:16 UTC.[3]
Upon opening the hatch, the crew detected a toxic smell and possible contamination in the form of droplets. They immediately closed the hatch, and ISS systems were activated to scrub the atmosphere of potential contaminants.[4] The hatch was reopened on 25 November and unloading of the cargo ship proceeded as planned. NASA said that outgassing from materials inside the pressurized cargo section was the likely source of the odor.[5] However, some within the Russian space industry believe that the smell and droplets are likely related to the departure of the previous Progress MS-27 cargo ship on 19 November 2024. They believe that ground control failed to purge the lines to transfer propellant from the spacecraft to the station's tanks before undocking. As a result, highly toxic hypergolic propellants could have remained in the lines and spilled onto the docking mechanism as Progress MS-27 undocked. When Progress MS-29 arrived, the remaining propellant on the docking mechanism was trapped inside the hatch, allowing it to enter the station when it was opened.[6]
