and the orders of the Second World War were put on board the Soyuz. In order to prevent the Progress MS-14 coronavirus from entering the station, it underwent additional disinfection before launch before being sent. First of all, disinfection of the internal surfaces and equipment, as well as the external surfaces of the goods delivered was carried out with the selection of control samples. After refueling the vessel and upgrading the equipment, additional disinfection was carried out to prevent the virus from entering the ISS.


Launch

in Europe. The number has a double significance because the cargo mission is the 75th Progress resupply flight to the International Space Station since 2000. Progress MS-14 was launched at 01:51:41 UTC from Baikonur Site 31/6 on a fast-track trajectory. Following a nominal launch, Progress MS-14 docked with ''Zvezda'' on the ISS at 05:11:56 UTC.


Docking

3 hours and 20 minutes after launch, Progress MS-14 successfully docked automatically to the rear port of ''Zvezda'' at 05:11:56 UTC on 25 April 2020, where it remained until 27 April 2021.


Cargo

The Progress MS-14 spacecraft delivered 2528 kg of cargo, with 1358 kg of this being dry cargo. The following is a breakdown of cargo bound for the ISS: * Dry cargo: 1358 kg * Fuel: 700 kg * Oxygen: 50 kg * Water: 420 kg


Undocking and decay

After its mission was completed, Progress MS-14 undocked from the station on 27 April 2021 filled with disposable trash. It re-entered the
