Philae lander has fallen silent, Rosetta scientists say

Lander which became first to touch down on a comet is not responding to commands, raising fears it may have moved again

The Philae comet lander has fallen silent, European scientists have said, raising fears it has moved again on its new home millions of miles from Earth.

The fridge-sized robotic lab, which landed on comet 67P/Churyumov-Gerasimenko in November, last made contact on 9 July and efforts to reach it again have so far failed, experts working for the historic European Space Agency project said on Monday.
