Progress MS-28 (Russian:Прогресс МC-28), Russian production No. 458, identified byNASA asProgress 89, was aProgress spaceflight launched byRoscosmos to resupply theInternational Space Station (ISS). It is the 181st flight of a Progress spacecraft.
Launched fromSite 31/6 at theBaikonur Cosmodrome inKazakhstan atop aSoyuz-2.1a on Thursday, 15 August 2024, at 03:20:17UTC (08:20:17AQTT, local time at the launch site). Progress MS-28 will deliver approximately 2,621 kg (5,778 lb) of food, water, clothing, fuel, and equipment to the ISS for theExpedition 71 and to prepare the station for theExpedition 72 crew.
The spacecraft autonomously docked with the ISS on 17 August 2024, at 05:55:07 UTC UTC. It attached to the aft port of theZvezda module, replacing theProgress MS-26 spacecraft that was previously at the location.
After six months docked to the ISS, in preparation for the launch of theProgress MS-30 cargo mission, Progress MS-28 undocked on 25 February 2025 at 20:17:33 UTC. The braking maneuver started at 23:21 UTC and the spacecraft began to reenter Earth's atmosphere over the Southern Pacific Ocean around two minutes later. Its surviving debris were estimated to impact the ocean surface at around 01:05 UTC on 26 February.[4]
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.[5]
For this mission, Progress MS-28 was loaded with a total of 2,621 kg (5,778 lb) of cargo and supplies prior to launch. The cargo manifest includes the following:[4]
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.[4]
27 August 2024, 21:46 UTC: A 1,075.42-second burn increased velocity by 1.95 m/s (6.4 ft/s), raising the ISS's altitude by 3.4 km (2.1 mi) to 419.41 km (260.61 mi), preparing for Soyuz MS-25's departure and Soyuz MS-26's launch.
5 September 2024, 19:45 UTC: A 781.98-second burn increased velocity by 1.42 m/s (4.7 ft/s), raising the altitude by 2.48 km (1.54 mi) to 420.7 km (261.4 mi), finalizing adjustments for Soyuz MS-25's departure and Soyuz MS-26's launch.
4 October 2024, 08:44 UTC: A 1,207.62-second burn increased velocity by 1.66 m/s (5.4 ft/s), raising the altitude by 2.9 km (1.8 mi) to 419 km (260 mi).
13 November 2024, 16:47 UTC: A 1,894.4-second burn increased velocity by 2.82 m/s (9.3 ft/s), raising the altitude by 4.9 km (3.0 mi) to 417.23 km (259.25 mi), preparing for Progress MS-29's arrival.
19 November 2024, 20:09 UTC: A 330.90-second burn for collision avoidance delivered a 0.5 m/s (1.6 ft/s) velocity change, raising altitude by 800 m (2,600 ft) to reach a 430.86 km × 416.20 km (267.72 mi × 258.61 mi) orbit.
25 November 2024, 09:49 UTC: Another collision avoidance maneuver lasting 211.96 seconds, delivering a 0.3 m/s (0.98 ft/s) velocity change, raising altitude by 500 m (1,600 ft) to a 430.40 km × 417.81 km (267.44 mi × 259.62 mi) orbit.
22 December 2024, 01:10 UTC: A 811.3-second burn increased velocity by 1.3 m/s (4.3 ft/s), raising the ISS's altitude by 2.3 km (1.4 mi) to 416.43 km (258.76 mi), preparing for Soyuz MS-26's departure and Soyuz MS-27's launch.
11 January 2025, 17:45 UTC: A 1,155-second burn increased velocity by 1.8 m/s (5.9 ft/s), raising the ISS's altitude by 3.2 km (2.0 mi) to 416.71 km (258.93 mi), preparing for Soyuz MS-26's departure and Soyuz MS-27's launch.
1 February 2025, 08:58 UTC: A 1,227.2-second burn increased velocity by 1.82 m/s (6.0 ft/s), raising the ISS's altitude by 3.2 km (2.0 mi) to 417.44 km (259.39 mi), preparing for Soyuz MS-26's departure and Soyuz MS-27's launch.
20 February 2025, 01:30 UTC: A 1,341.2-second burn increased velocity by 1.95 m/s (6.4 ft/s), raising the ISS's altitude by 3.4 km (2.1 mi) to 419 km (260 mi), preparing for Soyuz MS-26's departure and Soyuz MS-27's launch.
