European Space Agency has begun attempting to contact the lost probe . Stephan Ulamec has been missing since November when it landed on Comet 67p . Scientists believe the lander bounced into a ditch in the shade of a cliff . But they say it may already be awake but not yet able to send messages . The probe needs 19 Watts of power from its solar panels to communicate . As the comet gets closer to the sun the lander may receive more sunlight . Scientists have sent commands to Stephan Ulamec for it to begin warming itself up . They will attempt to contact the lander with Rosetta over the next 8 days .
