Paris, Jun 14 (EFE).- The Rosetta mission’s Philae lander has sent signals that it has resumed operating after a seven-month hibernation period on the surface of Comet 67P/Churyumov-Gerasimenko, the European Space Agency, or ESA, said in a Twitter post.

“For 85 seconds, Philae ‘spoke’ with its team on ground, via Rosetta, in the first contact since going into hibernation in November,” the ESA said in a statement.

The Rosetta orbiter received a signal from Philae that indicated that the lander’s batteries had been reactivated and it was holding up well on the comet, the French National Space Research Center, or CNES, said.

The signal was received at the ESA European Space Operations Center in Darmstadt, Germany, on Saturday night.

The lander had shut down on Nov. 15, 2014, because its batteries could not get sunlight after the spacecraft ended up in a dark part of Comet 67P/Churyumov-Gerasimenko. EFE
