Each Progress mission delivers pressurized and unpressurized cargo to the station. The pressurized section carries consumables such as food, water, and air, along with equipment for maintenance and scientific research. The unpressurized section contains tanks of fuel, water, and gases, which are transferred to the station through automated systems.[3]
