MOSCOW, July 5 (Itar-Tass) - The Proton-M rocket blasted off from the launch pad 0.4 seconds earlier than planned, Roscosmos head Vladimir Popovkin told reporters.
It can be said definitely for the present that the rocket blasted off earlier than planned. When asked how earlier, he answered "0.4 seconds."
The Proton started taking off when the engines did not begin to work as planned, and combustion chamber pressure was 90 atm instead of 150 atm. First, the sequence diagram to start the rocket began working. As the rocket did not work as planned, the regular sequence diagram began working, and at the moment, something happened, he said.
