Roscosmos PAO: "RSC-Energia Completed Investigation of the Progress M-08M Docking Failure".

RSC-Energia has completed investigation of the Progress M-08M docking failure which occurred on Oct. 30, when the cargo vehicle was approaching the International Space Station, RSC-Energia PAO reported.
The Investigation Commission detected that disturbances in the Kurs RF docking support system had been caused by non-compliance of the Kurs rendezvous control antennae connection on the Pirs module with high-frequency link standards. The non-compliance was first detected in the 4-port configuration of the ISS RS.
The Commission, together with the ISS crew, has proposed recommendations for further automatic docking sequences of Soyuzes and Progresses, including MCC-M ops operations and upgrades of the Zvezda harness in order to maintain proper switching of the Kurs antennae wrt a relevant docking port.
The Kurs equipment installed on the ISS is accepted for further operations.

The Technical Committee established for the analysis of the situation occurred on 30.10.2010 during the automatic rendezvous and berthing of the Progress М-08М vehicle to the Pirs Module of the International Space Station (ISS) Russian segment (RS) completed its work at S.P. Korolev Rocket & Space Corporation Energia.

Representatives of the Prime Contractor for the Kurs rendezvous and berthing radio system, Mission Control Center (MCC-M) and also organizations authorized by Roscosmos for supervision and control of activities related to the ISS RS took part in its work.

It was found that the cause of the interference occurrence in the Kurs system radio channel was nonconformance of the antenna connection for this system berthing, located on the Pirs Module to the required state of high-frequency channels. For the first time this nonconformance occurred in conditions of the system operation with the availability of four docking ports of the ISS RS.

The Committee together with the ISS crew elaborated recommendations for the automatic rendezvous and berthing for future vehicles Soyuz and Progress including ones to update the operating procedures performed by MCC-M and the ISS crew, as well as recommendations for the structural elements modification of the Zvezda Module onboard cable network for the assured antenna switching of the Kurs system, as applied to the docking port involved.

The Kurs system equipment installed onboard the ISS RS is approved for its further operation.

For reference:
  1. Currently four docking ports available on Modules Zvezda, Pirs, Poisk, Rassvet are used on the ISS RS for docking with Russian vehicles Progress M and Soyuz TMA respectively.
  2. Prior to docking at MCC-M commands onboard the Zvezda Module the Kurs equipment check activation was provided, which verified its low-frequency channel operability. The system high-frequency channel operability can be checked with the availability of the vehicle docked to the corresponding port.

Progress M-08M Departed from the ISS
:: 24.01.2011

Today, on Jan. 24, cargo vehicle Progress M-08M departed from the International Space Station.

At 03:40 a.m. MSK, a departure command for the automatic cargo vehicle was issued from the ISS. Three minutes later the Progress separated from the docking port on the Pirs module. The vehicle had been attached to this port since Oct. 30, 2010.

Unburnt parts of Progress M-08M fell down in remote area of the Pacific at about 09.7 MSK.

In parallel, preps for Progress M-09M launch continue at Baikonur. The cargo vehicle with about 2.5t of cargo for the ISS is slated for launch on Jan. 28.
