Progress M-UM (Russian: Прогресс М-УМ), is a specially modified Progress M 11F615A55, Russian production No.303,[5] developed by Roscosmos to deliver the Prichal module to the Russian Orbital Segment (ROS) of the International Space Station (ISS). It was launched on 24 November 2021 at 13:06:35 UTC, along with a Progress M propulsion compartment and has the pressurised cargo module removed to accommodate Prichal. This is the 171st flight of a Progress spacecraft.[2][6] It is the final flight of a Progress M and the first launch of a Progress spacecraft on a Soyuz 2.1b.[7]

Development[edit]

On 15 January 2011, RKK Energia announced that its Scientific and Technical Council (NTS) had reviewed and approved the preliminary design of the Node Module and associated hardware, including a special version of the Progress cargo ship designated the Progress M-UM spacecraft-module, intended for the delivery of the Node Module to the station. The space payload section for the Progress M-UM was dubbed KGCh. The Soyuz-2 launch vehicle was adapted for the launch of the Progress M-UM spacecraft-module, originally envisioned to take place in 2012, then 2019.[8] It was eventually signed for as completed in 2014 and kept in storage until processing and attachment with Prichal was started for launch in 2021. It is attached to the Prichal module by means of a newly developed transition compartment.

The Prichal module is the second addition to the ROS in 2021. Earlier modules were delivered and added in a similar manner. Progress M-UM is similar in design to Progress DC-1 that delivered Pirs in 2001 and Progress M-MIM2 that delivered Poisk in 2009, but with navigational systems and avionics hardware taken from the Progress MS variant.

Launch[edit]

A Soyuz-2.1b launched Progress M-UM to the International Space Station from Baikonur Site 31/6 on 24 November 2021, at 13:06:40 UTC for delivery of the Prichal module.[1][2][4] Due to the larger diameter of the Prichal module, the Progress M-UM was launched in a 4.1 m (13 ft) wide ST-type fairing.

Docking[edit]

Two days after launch, Progress M-UM automatically docked Prichal to the re-configured nadir (or Earth-facing) port of the Nauka module after removal of the module's nadir docking adapter by Progress MS-17. Progress M-UM will then remain in orbit for 30 days.

Expansion of Russian Orbital Segment[edit]

The ISS flight manifest drafted by Roscosmos at the end of summer 2020 set the launch of the Prichal module for 6 September 2021, with the docking to Nauka's nadir port two days later.[2] However, on 1 December 2020, the launch of Prichal slipped to three and four months after the Nauka. The planned launch date was on 24 November 2021.[1]

One port on Prichal is equipped with an active hybrid docking port, which enables docking with the Nauka module. The remaining five ports are passive hybrids, enabling docking of Soyuz and Progress vehicles, as well as heavier modules and future spacecraft with modified docking systems.[1]

A spacewalk is planned after Prichal's arrival at the station, with a second spacewalk planned for early fourth quarter of 2021. Six additional spacewalks will follow through 2022 to complete the integration of the Nauka and Prichal modules into the Russian Orbital Segment.[1]

Undocking[edit]

The Progress M-UM propulsion section is planned to remain docked at the station for 26 days. The propulsion section will then undock, revealing Prichal's nadir docking port for future Russian spacecraft.

Atmospheric entry[edit]

The propulsion section will re-enter in the atmosphere of Earth for destruction over the South Pacific Ocean.[6]

Notes[edit]

  1. ^ Prichal, the second module after Rassvet to use a port initially used by Soyuz or Progress spacecrafts, is not able to dock to SSVP ports like the Rassvet module. The port had the temporary docking adapter built to the SSVP-M or "Hybrid" standard, which comprises the traditional SSVP probe‑and‑drogue soft-dock mechanism and an APAS-95 hard-dock collar before Prichal's arrival.
  2. ^ The temporary docking adapter is the grey ring surrounding the docking probe of Progress MS-17.
