Progress MS-16 (Russian:Прогресс МC-16), Russian production No. 445, identified byNASA asProgress 77P, was aProgress spaceflight operated byRoscosmos to resupply theInternational Space Station (ISS). This was the 168th flight of a Progress spacecraft.
TheProgress-MS is an uncrewed freighter based on theProgress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It has the following improvements:[2][3][4][5]
ASoyuz-2.1a launched Progress MS-16 to the International Space Station fromBaikonur Cosmodrome Site 31 on 15 February 2021 following a two-day, 34-orbit rendezvous profile.[1][6][7] Progress MS-16 was docked on 17 February 2021, 06:26:47 UTC, using manual docking system operated byExpedition 64 commanderSergey Ryzhikov to thePirs module of theISS, where it remained until 26 July 2021, 10:55 UTC.[8]
On 4 February 2021, Roscosmos said that Progress MS-16 had been installed back into its processing stand inside the assembly building at Site 254 for final pre-launch operations and loading of fresh food items in its cargo bay. The ship's cargo included 600 kg of propellant for refueling, 420 kg of drinking water in the Rodnik system, 40.5 kg of pressurized gases with extra nitrogen supplies and 1,400 kg of various equipment and supplies, including the repair kit with reinforced glue patches for temporary sealing of the Transfer Chamber, PrK, in theZvezda Service Module (SM).[9]
The Progress MS-16 spacecraft was loaded with 2,460.5 kg (5,424 lb) of cargo, with 1,400 kg (3,100 lb) of this being dry cargo.[1]
The Progress MS-16 was expected to remain docked at the station until 23 July 2021, 12:45 UTC, when it would depart with thePirs module docked to it for destructive reentry four hours later over theSouth Pacific Ocean, which would also mark the first module to be decommissioned from use aboard the International Space Station. TheNauka module, which would replacePirs after its fiery reentry and subsequent destruction, was launched on 21 July 2021 at 14:58:25 UTC, for docking on 29 July 2021, at 13:25 UTC. However, due to post-launch telemetry and propulsion issues withNauka, the undocking of Progress MS-16 was delayed to 26 July 2021, at 10:55 UTC. The spacecraft, together with thePirs module, was successfully deorbited on the same day at 14:51 UTC.[8]
