Russia’s Soyuz-2.1a rocket lifted off from Site 31/6 at the Baikonur Cosmodrome on 3 July, carrying the uncrewed Progress MS-31 cargo ship on a resupply flight to the International Space Station. The launch at 22:32 Moscow time marked the second Russian logistics mission to the outpost this year and the 92nd Progress flight overall. Roscosmos said the spacecraft is loaded with roughly 2.6 metric tons of supplies, including about 1.2 tons of dry cargo for the Expedition 73 crew, 950 kg of propellant, 420 kg of drinking water and 50 kg of compressed nitrogen. Scientific hardware for experiments such as Impuls, Biopolymer and Separatsiya is also aboard. Progress MS-31 will follow a two-day, 34-orbit rendezvous profile before an automated docking with the station’s Poisk module at 00:27 Moscow time on 6 July. The mission follows the controlled de-orbit of Progress MS-29 on 2 July and is scheduled to remain attached to the complex for about six months.
