Progress MS-28, Russian production No. 458, identified by NASA as Progress 89, is a Progress spaceflight launched by Roscosmos to resupply the International Space Station (ISS). It is the 181st flight of a Progress spacecraft.
Launched from Site 31/6 at the Baikonur Cosmodrome in Kazakhstan atop a Soyuz-2.1a on Thursday, 15 August 2024, at 03:20:17 UTC (08:20:17 AQTT, local time at the launch site). Progress MS-28 will deliver approximately of food, water, clothing, fuel, and equipment to the ISS for the Expedition 71 and to prepare the station for the Expedition 72 crew.
The spacecraft is set to autonomously rendezvous and dock with the ISS on Saturday, 17 August 2024, at 05:56 UTC. It will attach to the aft port of the Zvezda service module, replacing the Progress MS-26 spacecraft that was previously at this location.
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.[4]
For this mission, Progress MS-28 was loaded with a total of of cargo and supplies prior to launch. The cargo manifest includes the following:[5]
Progress MS-28 cargo spacecraft performed a series of orbital maneuvers to maintain and adjust the International Space Station's (ISS) trajectory. These come in the form of periodic "reboosts" to counteract atmospheric drag on the station or collision avoidance maneuvers, moving the station to dodge a piece of debris flying through space.
