Roscosmos launched the Progress MS-35 cargo spacecraft from Baikonur Cosmodrome in Kazakhstan on Wednesday, sending it into orbit on a Soyuz-2.1b rocket for a planned automated docking with the International Space Station’s Poisk module on Saturday. The mission is carrying more than 2.4 tonnes of supplies, including propellant, water, oxygen, food, medicines and maintenance equipment.
The spacecraft separated normally from the rocket’s third stage after lift-off and continued on its way to the station. The launch had been delayed after a technical issue with the booster’s third stage, but the flight proceeded successfully once the problem was resolved.
Alongside routine logistics, the shipment also includes equipment for several experiments, among them Teledroid, Biopolymer, Virtual, Vampir, Uragan and Separation. The cargo run restores the ISS resupply flow after the postponement and extends Russia’s role in delivering consumables and reboost propellant to the orbital outpost.
