Progress MS-11 (Russian: Прогресс МC-11), identified by NASA as Progress 72P, was a Progress spaceflight operated by Roscosmos to resupply the International Space Station (ISS). This was the 163rd flight of a Progress spacecraft.

History

The Progress-MS is an uncrewed freighter based on the Progress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It has the following improvements:[2][3][4]

  • New external compartment that enables it to deploy satellites. Each compartment can hold up to four launch containers. First time installed on Progress MS-03.
  • Enhanced redundancy thanks to the addition of a backup system of electrical motors for the docking and sealing mechanism.
  • Improved Micrometeoroid (MMOD) protection with additional panels in the cargo compartment.
  • Luch Russian relay satellites link capabilities enable telemetry and control even when not in direct view of ground radio stations.
  • GNSS autonomous navigation enables real time determination of the status vector and orbital parameters dispensing with the need of ground station orbit determination.
  • Real time relative navigation thanks to direct radio data exchange capabilities with the space station.
  • New digital radio that enables enhanced TV camera view for the docking operations.
  • The Ukraine Chezara Kvant-V on board radio system and antenna/feeder system has been replaced with a Unified Command Telemetry System (UCTS).
  • Replacement of the Kurs A with Kurs NA digital system.

Pre-launch

In 2014, the launch was scheduled for 16 April 2018. In November 2018, delays with the launch of the EgyptSat-A spacecraft and required the launch to 28 March 2019, the Kommersant newspaper reported. In January 2019, RIA Novosti reported that the launch had been pushed to 4 April 2019.[5]

Launch

Progress MS-11 launched on 4 April 2019, at 11:01:34 UTC [1] from the Baikonur Cosmodrome in Kazakhstan. It used a Soyuz-2.1a rocket.[6][7]

Docking

Progress MS-11 docked with the docking port of the Pirs module just 3 hours and 22 minutes after the launch, at 14:22:26 UTC.[8]

Cargo

The Progress MS-11 spacecraft delivered 3,400 kg of cargo, with 1,400 kg of this being dry cargo. The following is a breakdown of cargo bound for the ISS:[5]

  • Dry cargo: 1,400 kg
  • Fuel: 900 kg
  • Compressed Air: 47 kg
  • Water: 420 kg (Rodnik system)

Equipment for several life science experiments, including Bioplenka, Konstanta-2, Produtsent, Mikrovir, Struktura, Biodegradatsiya and Kristallizator. The spacecraft also carried the Faza vessel for growing water plants and the associated lighting system for the Ryaska educational experiment.[5]

Undocking and decay

It undocked at 10:43 UTC, on 29 July 2019. And decay in the atmosphere and its debris entered the Pacific Ocean, on the same day.
