Progress MS-27 (Russian: Прогресс МC-27), Russian production No. 457, identified by NASA as Progress 88, is a Progress spaceflight launched by Roscosmos to resupply the International Space Station (ISS). It is the 180th flight of a Progress spacecraft.
The spacecraft, Progress MS-27 No. 457 arrived at the Baikonur Cosmodrome on 14 September 2023 after being shipped from Energia manufacturing facility in Russia by rail. The spacecraft underwent several months of pre-launch preparations including inspections, testing, fueling, and integration with the Soyuz-2.1a launch vehicle. After several schedule adjustments, the spacecraft was launched on 30 May 2024 at 09:42:59 UTC (14:42:59 AQTT, local time at the launch site). After a nominal two-day free flight, it docked with the zenith (space facing) port of the ISS's Poisk module on 1 June at 11:46:11 UTC.[4]
After a nearly six-month stay at the ISS supporting Expedition 71, Progress MS-27 undocking on 19 November 2024, at 12:53 UTC, to make way for a new cargo vehicle. After a free flight of about three and a half hours, the spacecraft initiated a deorbit burn at 16:11 UTC. It reentered Earth's atmosphere and disintegrated over the Pacific Ocean, with debris projected to impact the ocean at 16:51 UTC.[4]
