The launch of the carrier rocket heavy class “proton-M” which should put into orbit the American communication satellite Echostar-21, can be moved to the beginning of June. About it reports “Interfax” citing a source at the cosmodrome Baikonur.

“It is clear that due to unresolved technical problems launches to resume in late may fail, and the launch of “Proton” with the satellite EchoStar 21 is shifted at least at the beginning of June,” — said the Agency interlocutor.
