S.P. Korolev RSC Energia,
Baikonur launch site - Baikonur cosmodrome
The launch of Proton-M launch vehicle (LV) with Upper Stage 11С861-03 and three spacecraft (SC) GLONASS-M was performed from
the Baikonur cosmodrome at 13:25 Moscow time.
The objective of the launch is the generation completion of the Russian constellation of Global Navigation Satellite System GLONASS.
As a result of the Proton LV off-nominal operation the Ascent Unit consisting of three satellites GLONASS-M and Upper Stage 11С861-03 was injected into off-design flight trajectory and submerged in the Pacific ocean 1500 km to the north-west of Honolulu, administrative center of Hawaii.
The Commission to reveal the trouble causes and establish a procedure for further actions is appointed at Federal Space Agency (Roscosmos).
- US DM developed and manufactured by S.P. Korolev RSC Energia are designed for SC delivery from low-earth orbits to high-energy orbits including geostationary orbit and also to translunar and solar system planets trajectories. They operate using ecologically safe propellant components (LOX and kerosine). These blocks have long-standing operation statistics confirming their high technical and operating characteristics. Currently their modern modifications are used.
