The carrier rocket "proton-M" with telecommunication satellite "Express-80" and "Express-103" was launched from the Baikonur cosmodrome, the broadcast was carried out on the Internet representation of " Roscosmos ".

"Contact lifting ", - declared the speaker during the broadcast. He later said about the successful separation of the satellites from the launch vehicle.

The launch took place in the reserve day. Wednesday, Roskosmos, said about the postponement of the launch of "Proton" from 30 to 31 July For additional inspections of components and assemblies. Later the source of the Last news in the aerospace industry explained that the reason for the transfer was the observation during the inspections of the control system upper stage " breeze-M ".

As before said, " Roscosmos ", the unit For acceleration of "Briz-M" with the satellite "Express" will separate from the third stage rocket "proton-M" to 0. 35 GMT. Further removal of spacecraft into the target orbit with the lowest altitude 16, 6 thousand kilometers and the highest 54, 9 thousand kilometers will be conducted at the expense of five engine burns " Breeze ".

"Express-80" must be separated from the upper stage at 18. 24 GMT, "Express-103" - in 18. 41 GMT. So, this will be the longest flight in history "Proton" - around 18 hours and 16 minutes.

As missile capabilities do not allow to deliver Satellites "Express" to the geostationary orbit (circular orbit with altitude of 35 786 km), then after separation of the "Breeze", "Express-80" will go to her 152 days using its own electric propulsion, and "Express-103" - 160 days.

according to the enterprise satellite communications, Satellites are Expected to enter into use in January-February 2021.

For the rocket "proton" this will be the 1st and only in 2020 start. It will also be the ninth space start-up Russia In the current year.

Send "parlay Bets" into orbit was planned for the end of March, but the missile had to return to the Russian capital For the replacement of defective components, which are found at the spaceport. According to the newspaper " Vedomosti ", was said about the faulty bolts used For fastening pipelines second stage of the rocket. The General Director of "Rosatom" Dmitry Rogozin told that the marriage was admitted in 2015-2016 in the manufacture of individual components at the Ust-Katavsky car-building plant in Chelyabinsk region.

The space device "Express-80" and "Express-103" manufactured by "Information satellite systems named after Reshetnev" in the interests of the enterprise "Space communications" at the site-based satellite platform " Express-1000H ". It is planned that they will work for fifteen years in geostationary orbit in the setups 80 and 96 degrees, 5 degrees East longitude, respectively. The satellites are designed To provide fixed and mobile communications, digital broadcasting, high-speed web access and data transfer in C-, Ku - and L-bands on the territory of the Russian Federation and in the CIS States.
