Manifest

Each Progress mission delivers over a thousand kilograms of supplies in its pressurized section, accessible to crewmembers. These supplies include consumables such as food, water, and air, along with equipment for maintenance and scientific research. In its unpressurized section, the spacecraft carries tanks of water, fuel, and gases to replenish the station’s resources and sustain its onboard atmosphere. These resources are transferred to the station through an automated process. For this mission, Progress MS-30 was loaded with a total of of cargo and supplies prior to launch. The cargo manifest includes the following: * Pressurized supplies: * Fuel: * Water: * Nitrogen gas: Among the supplies loaded into the pressurized compartment was a new Orlan-MKS spacesuit.
