Comet lander Philae wakes from hibernation

The comet landing of Philae enthralled the entire mankind in November last but soon it went into hibernation and the European space Agency thought it was lost forever on the Comet 67P/Churyumov-Gerasimenko.

The latest bulletin offered by the ESA offers that contact was made at its European Space Operations Center in Darmstadt, Germany at 22:28 CEST on June 13. “The lander is ready for operations“.

“We have also received historical data – so far, however, the lander had not been able to contact United States earlier”, say the researchers.

Ulamec and his team have so far had access to 300 data packets, but another 8,000 are in Philae’s memory.

The picture released by the European Space Agency ESA on Wednesday, November 12, 2014 was taken by Rosetta’s lander Philae shortly after its separation with the lander’s CIVA-P imaging system and captures one of Rosetta’s 14 metre-long solar wings.

“Rosetta has been beaming commands every couple of weeks to Philae, in the hope that it will signal back, and now it has”.

Leo Enright spoke to Newstalk Breakfast about the news that comet lander Philae has “woken up”.

Comet “67P” is now 215 million kilometres (134 million miles) from the Sunday and 305 million km from Earth, racing at a speed of 31.24km a second.

Scientists also hope that Philae’s restart will allow them to pinpoint where on the 2.5-mile (4-kilometer)-wide comet the washing machine-size probe landed.

The mission of Rosetta and its Philae robot, which took more than twenty years of work, seeks to unravel the evolution of the solar system since birth, comets are considered remnants of primitive matter.

It worked for 60 hours before going to sleep when its solar-powered battery ran flat but the comet has now sparked into life, transmitting signals for two minutes, as well as 40 seconds worth of data.

“We were surprised, yes, because we didn’t expect it at all last night, on a weekend – it’s really exciting”, Martin said.

Perihelion, the closest point to the Sunday in the comet’s orbit, will be on August 13, after which “67P” will veer off again into the deeper reaches of space.

The ESA said on Thursday that it may have found the exact location of the comet from images and other data from the mothership, which was previously unknown.
