Progress MS-13 will deliver close to 2,480 kilograms of supplies to the ISS, including around 420 kilograms of water in the containers of the Rodnik system, around 50 kilograms of pressurized oxygen in tanks, around 650 kilograms of propellant for refueling and around 1,350 kilograms of dry cargo, such as food rations, hardware for life-support and flight control systems, hygiene and medical supplies. In addition, the crew was also scheduled to receive a new tread for the treadmill.
