Ground controllers said Friday they would stop sending commands to comet probe Philae, announcing it was "time to say goodbye" to the robot lab resting after a captivating science mission. "There is indeed little hope to still get a signal from the lander," said Philae project manager Stephan Ulamec of the German Aerospace Center DLR. The DLR, host of the Philae control centre, said the probe was "probably" covered with comet dust, and shaded from the Sun's battery-replenishing rays on the surface of its alien home.
Britain said Friday a Hong Kong bookseller believed detained by China was "involuntarily removed to the mainland", in its strongest comments yet on a case that has rocked the city amid fears its promised freedoms are being eroded. The disappearance of Lee Bo, who holds a British passport and published books critical of Chinese politics, was a "serious breach" of an agreement signed with Beijing before the city was handed back to China in 1997, said foreign secretary Philip Hammond in a new report. There are still question marks over what has happened to Lee, 65, the only publisher to have disappeared from Hong Kong.
