On Monday 20 January, ESA’s comet-chasing spacecraft Rosetta will wake up from 31 months of deep space slumber. ESA will streaming live from ESOC, Darmstadt, Germany, with full coverage of the day’s historic events as they unfold, starting at 09:15 GMT (10:15 CET)

Rosetta’s computer is programmed to re-establish contact with Earth on 20 January, starting with an ‘alarm clock’ at 10:00 GMT. Immediately afterwards, the spacecraft’s startrackers will begin to warm up, taking around six hours. Rosetta will then send a signal to Earth to announce that it is awake. The first window of opportunity to receive a signal is between 17:30-18:30 GMT.
