Russian orbital launch vehicle. The Angara 5A was a proposed variant of the modular launch vehicle that would use four universal rocket modules (URM's) as boosters surrounding one URM in the core, with a LOx/LH2 upper stage. It could put 5.0 metric tons into geosynchronous orbit, or 8.0 metric tons into geosynchronous transfer orbit.

2014 December 23 - . 05:57 GMT - . Launch Site: Plesetsk. Launch Complex: Plesetsk. LV Family: Angara. Launch Vehicle: Angara 5A.
  • IPM - . Nation: Russia. Class: Technology. Type: Re-entry test vehicle. USAF Sat Cat: 40355 . COSPAR: 2014-085A. Apogee: 39,083 km (24,285 mi). Perigee: 36,163 km (22,470 mi). Inclination: 0.9100 deg. Period: 1,530.92 min.

    First launch of the Angara-A5 booster, composed of five standard URM-1 modules and a Briz-M upper stage. Four URM-1's, clustered around a URM-1 in the core, formed the first stage. The core URM-1 was the second stage. The four first stage URM-1's separated at 06:01 GMT at an altitude of 82 km; the core URM-1 shut down and separated at 06:03 GMT at an altitude of 148 km, reentering downrange near Tomsk. The nose fairing was jettisoned 10 seconds later. The third stage was a URM-2, powered by the RD-0124A engine; it reached a marginally suborbital trajectory and, after separating from the upper composite section, reentered in the Philippine Sea at a range of 2320 km from the launch site. Meanwhile, the fourth stage, a standard Briz-M (S/N 88801) propelled the stack into a 250 km, 63 deg parking orbit with a burn starting at 06:11 GMT. After coasting to the equator, two perigee burns at 07:03 and 09:26 GMT boosted the apogee to 5,000 km and then 35,800 km, while reducing inclination to 60.6 deg. The Briz-M's additional propellant tank (DTB), now empty, was jettisoned into a 433 km x 35,808 km x 60.6 deg orbit. The payload on this flight was a dummy satellite called the IPM. The stack coasted to apogee and at 14:44 GMT, began the fourth burn to enter circular geosynchronous orbit. At 14:57 GMT the Briz sent a simulated separation command, but the payload remained attached to the stage as intended. After a few more hours, two burns of the Briz stage's SOZ auxiliary engines moved the stack to a graveyard orbit a few hundred kilometers above GEO. This was the first GEO mission ever launched from Plesetsk.
