Seven months after contact with Philae is lost, the comet lander from the Rosetta spacecraft of the European Space Agency (ESA) has finally communicated back to planet Earth on Saturday. The agency confirmed Sunday that the probe was able to send a signal back to the living planet in just over a minute.

The Rosetta spacecraft deployed its Philae lander on the surface of Comet 67P/Churyumov-Gerasimenko in November. The daring mission, which has traveled 6 billion kilometers for more than a decade, was a momentous breakthrough in the expedition of making a comet landing by a spacecraft.
Following its first comet touchdown in space history, the Philae lander was able to send pictures and other data back to Earth. Unfortunately, Fox News has learned that the batteries of the comet lander ran out, forcing its systems to shut down after almost 60 hours of establishing communication with Earth.
And after Philae's seven-month hibernation, the European Space Operations Center in Darmstadt, Germany finally reestablished signals at 10:28 p.m. (4:28 p.m. ET) on Saturday. According to USA Today, the comet lander has managed to send signals back to Earth after approaching the sun, which awakened its depleted batteries after its solar panels have absorbed enough light.
"I'm not really surprised it happened, but if you wait for several months and then suddenly in the middle of the night you get a call saying 'we have a signal from Philae,' it's exciting," German Aerospace Center project manager Stephan Ulamec said. "We're very happy."
Ulamec added that the Philae lander have been awake for several days before sending signals back to Earth. For 85 seconds, hundreds of historical data packages have been sent back home for analysis. However, scientists are still waiting for more information since there are still over 8,000 data packets in the lander's mass memory, as stated on a written post on the Rosetta blog.
Before reestablishing communication this weekend, Rosetta has been listening out for the Philae since March 12, Telegraph revealed. The next opportunity to communicate with the comet lander should come on Sunday night.
Meanwhile, comets almost positively hold significant pieces of evidence about the original resources that went into building the solar system over 4.5 billion years ago. And the pictures and the data from Philae's successful comet touchdown and exploration showed an immense opportunity to directly illustrate a cosmic wonder by showing some obscurities surrounding the icy relics from the formation of the solar system.
