Specialists are currently reviewing five versions of the output to the non-target orbit two European navigation satellites “Galileo» (Galileo Sat-Sat-5 and 6), the source said in an emergency commission to investigate the causes of abnormal situation.
«Among the possible causes of the incident, we consider the external impact on the parent unit exceed the capabilities of a thruster (RDMT), one of the barrier nozzles ligaments engine debris, unintended disclosure of the solar cell of one of the spacecraft during launch head unit “- said the source RIA” Novosti ».
In addition, the Russian experts among the possible reasons cited entry errors flight mission and unintended operation of the gyro platform. “But these versions have not yet been confirmed by the analysis of telemetry,” – said the agency interlocutor.
Earlier Thursday, it was reported, according to which the failure of the upper stage “Fregat-MT”, because of which the spacecraft were an unplanned orbit, occurred due to incorrect operation of the control system, manufactured by the Moscow Federal State Unitary Enterprise “Scientific-Production Center of Automatics and Instrument Academician Pilyugina” (NPTSAP).
However, the head of service information policy of the Joint Rocket and Space Corporation ( ACCD) Igor Burenkov said that closure of the commission to investigate the state of emergency to draw conclusions about the causes of abnormal excretion of satellites “Galileo” prematurely.
In addition, it was found out that you were in orbit nonisobaric European satellites were not insured, so If found lost the European Space Agency will have to book them again for as long as the budget is not enough.
The total cost of the navigation project “Galileo” is about 7 billion euros. Each satellite system will cost about 40 million euros. Running the Russian “Soyuz – ST” with komodroma Kourou in French Guiana costs 65-70 million euros.
Recall, August 22 Launch vehicle “Soyuz-ST-B” with the European spacecraft navigation system ” Galileo FOC »launched from Kourou in Guiana Space Center in French Guiana.
The launch was nonstandard, and aids were an unplanned orbit, where they can not use the title. Starting full operation of services as a result of Galileo will be rescheduled at a later date, the details of the failed launch from ESA has requested the European Commission.
The new satellites sent into orbit by the EU program “Galileo”, became the first of a new series of spacecraft , entirely made in Europe. Satellites called “Dores” and “Milena” names two winners of the drawing contest for European schoolchildren.
