Scheduled for March 5 launch from Baikonur launch vehicle "Proton" American spacecraft "Sirius FM-6" will be postponed to a later date, reported to "Interfax" Space Center "South." "The launch of the U.S. unit has been postponed. It is possible that the unit itself will have to be transported on a manufacturing company in the United States," - said the agency interlocutor. To this end, the spacecraft will return to the factory in the American Corporation Space Systems Loral (SSL).
source at the cosmodrome "Baikonur" explained "Interfax" that the stop occurred at the request of the customer's start-up, which is necessary to conduct additional satellite testing at the factory. According to preliminary data, the immediate cause that caused the cancellation of start-up, have a problem with the disclosure of solar panels on the spacecraft, SES-4, launched from Baikonur on the night of Feb. 15. "Normally," one of the batteries was not revealed to the disclosure had to "shake" satellite - to shake his maneuvering engines. As a result, the problem was fixed. Sirius FM-6 is based on the SL-1300 platform, the same as that of the satellite SES-4. The system of disclosure of solar panels in both satellites is similar. The manufacturer must ensure that the problem with disclosing the identity was refine or satellite, "- said a source. According to him, depending on what will be the amount of rework, shift start may be from one to six months.

It was to replace the Sirius FM-1 and FM-2 satellites, which would have reduced the HIEO-constellation from three to two satellites, but it was later decided, that FM-6 would also be placed into the geostationary orbit at 116.15° west.
