Russia has launched its third and final demonstration flight of the Angara A5 rocket on Monday, December 27. Angara is being developed and built by the Khrunichev State Research and Production Space Center and is intended to replace several existing launch vehicles.
Angara attempted to place its 2,400 kg mass simulator in a near geostationary orbit (GEO) using a new Persei upper stage. After a few hours, the Persei upper stage was to perform two burns to place the payload in a graveyard orbit, a few hundred kilometers above GEO. Russian reports, however, suggest that Persei only reached an initial low Earth parking orbit before suffering an engine failure.
