Robot lab Philae `silent`, says worried ground control

Paris: Europe`s robot lab Philae has fallen "silent" on the surface of a comet zipping towards the Sun, said ground controllers Monday who fear it may have shifted out of radio reach.

"The lander could have moved," the German Aerospace Center (DLR) said in a statement, adding: "even a slight change in its position could mean that its antennas are now obstructed".
