There was unbridled joy at the European Space Agency’s Operations Centre in Darmstadt, Germany. News which had just travelled 800 million kilometres through space. The comet probe Rosetta was awake and ready to get back to work.
Rosetta had powered up again after it was deliberately shut down three years ago in readiness for this mission.
So there were no Monday morning blues as it began an unprecedented journey to orbit and land on the comet Churyumov – Gerasimenko.
Rosetta’s on-board alarm clock had gone off at ten in the morning but it was a groggy start. It took just over seven hours before the spacecraft’s tracking navigation gear was warmed up and a message sent back to earth – ready to go.
