“Resurs-P” No. 2 and Astra 2G Launched into Orbit


Last weekend the aerospace industry of Russia pleased with two successful launches.

On December 26, the carrier rocket “Soyuz-2.1b” successfully launched promising Russian spacecraft of remote sensing of the Earth “Resurs-P” No.2. And on December 28, 2014 from the launch pad 200 of Baikonur Cosmodrome it was started the launch vehicle (LV) “Proton-M” with the upper stage (RB) “Briz-M” and telecommunications spacecraft (SC ) Astra 2G.

Both the launches took place in the normal mode. The spacecrafts were successfully placed on the target orbit.

The carrier rocket “Soyuz-2.1b” was created in FSUE “TsSKB-Progress” (Samara) and is a modification of “Soyuz-2″. In comparison with the option “1a” it has an engine with increased power characteristics at 3th stage. “Soyuz-2.1b” in relation to the previous version has more accurate removal, stability and control, increased payload mass.

Russia’s Soyuz-ST-B Places Four Communications Satellites into Orbit


The Russian Soyuz-ST-B carrier rocket with the Fregat upper stage took off from the Kourou spaceport in French Guiana to put O3b communications satellites into orbit. This was stated by a spokesman for the Russian Federal Space Agency (Roscosmos).

“The Fregat upper stage and four communications satellites have detached from the third stage of the Soyuz-ST-B carrier rocket. The subsequent injection of the satellites into final orbit will be achieved via several activations of the Fregat service propulsion system. This is the tenth launch from the spaceport in French Guiana,” the spokesperson reported.

It should be noted that four O3b communications satellites on board the Soyuz carrier rocket have been designed and built by Thales Alenia Space to become a part of the medium orbit satellite constellation providing broadband internet access in different parts of the world (Asia, Africa, Latin America and the Middle East).

Russia’s Proton Places Telecommunications Satellite into Orbit


The Briz-M upper stage and Yamal-401 telecommunications satellite separated from the Proton-M carrier rocket, which was launched from the Baikonur Cosmodrome. This information was presented by the press service of the Russian Space Agency.

“The spacecraft was put into orbit at 12:17 Moscow time,” the press center of the Federal Space Agency reported.

It should be noted that the Yamal-401 satellite designed and built by ISS Reshetnev Company for the Russian operator Gazprom Space Systems is capable of relaying continuously signals in Europe and Asia. The satellite is fitted with 53 transponders and six antennas in C/Ku-bands. The Yamal-401 is the third spacecraft created on the basis of the heavy-class Express-2000 platform. The weight of the satellite is 2,976 kilograms, the power used to carry a payload is 11 kW, and the life span is 15 years.
