BAIKONUR COSMODROME, Kazakhstan, 24 September 2019 – The launch of a Proton launch vehicle with the EUTELSAT 5 West B / Mission Extension Vehicle-1 satellites scheduled for 30 September was postponed today due to an issue encountered during electrical testing of the Integrated Launch Vehicle. The issue is currently under investigation by Khrunichev State Research and Production Space Center (Khrunichev).Khrunichev and International Launch Services (ILS) will reestablish a new launch date once the issue has been resolved. The vehicle and satellite remain in a safe configuration.For updates, please check the ILS website, www.ilslaunch.com .
25 Sep, 03:45Proton-M launch postponed because US satellite was attached incorrectly — sourceThe source added that "the Briz-M control system for the upper stage is operating in the routine mode"MOSCOW, September 25. /TASS/. The launch of the Proton-M carrier rocket with European satellite Eutelsat-5WB and US spacecraft MEV-1 was postponed because the US satellite was attached incorrectly, a source in the space rocket industry told TASS on Wednesday."Specialists from Roscosmos [Russia's space corporation] and MOKB Mars [manufacturer of Briz-M control systems] have established the reason of malfunction. The problem emerged because the US spacecraft was not attached correctly to the upper stage," the source said.The source added that "the Briz-M control system for the upper stage is operating in the routine mode."He added that "it may take several days to fix fix the problem with the MEV-1 satellite."Another source in the space rocket industry told TASS that malfunction revealed during pre-launch checks "manifests in electromagnetic interference in the Briz-M control system."TASS does not have an official confirmation of the information provided by the sources.The press service of Roscosmos told TASS on Tuesday that the launch of the Proton-M carrier rocket initially planned for September 30, was postponed because of additional checks of the upper stage.

..."The specialists of Roscosmos and the Mars Design Bureau [designer and manufacturer of the Briz-M control system] have identified the cause of the failures: the problem arose because the American spacecraft was connected in the wrong circuit to the upper stage," the agency’s interlocutor noted. He added that "the control system of the Briz-M overclocking unit is working normally."According to the agency’s source, "it may take several days to fix problems connecting the MEV-1 satellite." ...
Can't see any mention of an adapter between the two satellites. Does that mean that the MEV docking system holds the Eutelsat during launch?
