MOSCOW (Roscosmos PR) — Today, December 14, 2020, at 05:50 UTC, the Angara-A5 heavy-class carrier rocket was successfully launched from Russia’s Ministry of Defence State Test Space Center (Plesetsk cosmodrome) as part of flight design tests of the Angara rocket space complex. The launch vehicle was acquired by ground means of the VKS Titov Main Test Space Center.

Prelaunch preparation and launch of the carrier rocket were conducted by combat crews of the Space Forces of the Aerospace Forces and enterprises of Roscosmos. At the estimated time, 12 minutes 28 seconds after the liftoff, the Angara-A5.2L space rocket orbital block including the Briz-M upper stage and a spacecraft weight mockup separated from the third stage of the launch vehicle. Further injection of the orbital block into the target orbit is carried out with the help of the Briz-M propulsion system.

Universal rocket modules URM-1 and URM-2 serve as the basis for the Angara family carrier rocket development. Various class Angara launch vehicles are built using several universal rocket modules. One URM-1 is used as part of the Angara-1.2 light-class launch vehicles. The maximum number of URM-1 can be a three-stage heavy-class Angara-A5 launch vehicle.

Angara rockets do not use aggressive and toxic propellants significantly increasing environmental safety both in the areas adjacent to the launch complex and in the drop zones. Russia’s Ministry of Defense and Roscosmos are the government customers of the Angara space rocket complex, with Khrunichev Center being the lead developer and manufacturer.
