The ILS Failure Review Oversight Board (FROB) concluded its review on August 13, concurring with the conclusions of the Russian State Inter-agency Commission on the root cause and the associated corrective action plan of the July 2, 2013 Proton M/Block DM mission failure with three GLONASS navigational satellites for the Russian Federal Government.
The members of the FROB agreed with the findings of the Russian investigation that the root cause of the failure was due to the improper installation of the three yaw angular rate sensors located on the Proton launch vehicle, which caused the vehicle to deviate from its flight path shortly after lift-off.
“We very much appreciate the time, effort and participation of our customers, the insurance underwriters and technical experts in the FROB process. They worked tirelessly with us to ensure that the review was conducted thoroughly. As we work towards the return to flight of the Proton vehicle, we thank all of our customers for their continued support,” said ILS Vice President of Programs and Operations, John Palmé.
The ILS Proton return to flight mission will be the Astra 2E satellite for SES on September 15, 2013. The scheduling of the remainder of the ILS Proton near term manifest for 2013 is currently being determined.
