The loss of a multi-million pound weather mapping satellite was due to programming errors, the Russian deputy prime minister has said.
Dmitry Rogozin said Meteor-M had been programmed for take-off from a different space station.
Speaking to Russian state TV, he blamed "human error". "The rocket was programmed as if it was taking off from Baikonur," he told the Rossyia 24 TV channel. In fact the rocket was actually taking off from new base Vostochny, in the east of the country.
