EU satellites fired into wrong orbit by 'software bug' 

Two satellites commissioned by the European Union were accidentally sent into the wrong orbit at launch because of a simple software bug - potentially rendering the multi-million pound devices less capable than intended, or even entirely useless

An anonymous source from Russian space Agency Roscosmos told Osho3mtech that: “The nonstandard operation of the integrated management system was likely caused by an error in the embedded software. As a result, the upper stage received an incorrect flight assignment, and, operating in full accordance with the embedded software, it has delivered the units to the wrong destination.”

Also  Russian newspaper Izvestia reports that a software error in the upper stage, which was developed by a Russian government-owned corporation, was the likely cause.
