While the previous Russian government Proton M launch of the Express AM-6 communications spacecraft did not go entirely to plan with a “slightly short “achieved orbit resulting in a longer than planned final positioning phase for the spacecraft, the follow-on commercial Proton M flight of Astra 2G marketed by ILS has had its own Breeze M upper stage issues – this time pre-launch. A gyroscope fault was found on the upper stage, and, as a result, the gyroscope component has had to be changed. This necessitated the Breeze M stage being dismounted from the rocket and procedure has delayed this launch well into December. The delay is also likely to have a knock-on effect on the rest of the Proton launch schedule.
